Now, in a project led by the Georgia Tech Research Institute (GTRI) in collaboration with the Georgia Institute of Technology (Georgia Tech) researchers are closing the gap between Earth-based simulations and the true space environment by sending experimental materials to the International Space Station (ISS) for several months of in-orbit exposure. In a rare chance for space research, where most hardware is either left in orbit or burns up on reentry, they are getting those samples back for detailed analysis on Earth.

The materials are set to launch to the ISS in the near future as part of the Materials International Space Station Experiment 22 (MISSE-22), a testbed attached to the outside of the station. Mounted on the forward-facing side of the ISS to ensure predominant exposure to highly corrosive atomic oxygen, the test samples will spend several months enduring the extreme temperatures, radiation, and reactive environment of low Earth orbit. The team is testing a selection of lightweight, research-grade polymers designed to survive these harsh conditions. Once the samples return to Earth, engineers will examine how they held up and use that data to enhance the strategic of future satellite constellations.

This project represents a collaboration across government, academia, and industry, bringing together GTRI, Georgia Tech, the Air Force Research Laboratory (AFRL), the University of Texas at El Paso (UTEP), a California-based R&D firm Hedgefog Research Inc., and DuPont de Nemours, Inc. The research is also supported by Aegis Aerospace, which owns and operates the MISSE Flight Facility platform aboard the ISS.

Why Space is So Hard on Satellites 

Harsh conditions in low Earth orbit — the region of space extending from approximately 100 miles to over 1,000 miles above Earth, where many satellites and the ISS travel — can darken, roughen, and weaken spacecraft surfaces over time. That damage shortens satellite lifetimes and requires engineers to add extra layers of protection, increasing overall logistical burden and mission costs. 

Optimizing material durability is a strategic necessity, explained Elena Plis, a GTRI senior research engineer and principal investigator for the project, because every additional unit of shielding increases the cost of getting to orbit. To design lighter, more resilient materials, researchers need to examine how they degrade in a true space environment. However, most hardware is built for a one-way trip — designed to operate in orbit and then burn up on reentry, taking that valuable material data with it.

“The beauty of this type of experiment is that the materials return to Earth,” said Plis, who is also an affiliate of the Georgia Tech Space Research Institute. “For many missions, stuff is sent up and never seen again. Being able to test returned samples from real space conditions is unique, and I can’t stress enough how exciting that is for us.”
 

A New Generation of Polymers Head for Space

Instead of relying on familiar spacecraft materials like DuPont’s Kapton — a tough, heat-resistant polyimide plastic film that has coated spacecraft exteriors since the Apollo era — the team is sending up a set of new, lightweight, research-grade polymers. These materials are designed to improve the survivability of assets against space’s unforgiving elements.

Plis and her collaborators started with dozens of candidate materials they developed. To earn a spot on the MISSE-22, a sample has to be transparent or translucent, so light can pass through it, and researchers can examine how its optical properties change in orbit. The materials also have to be tough enough to withstand intense atomic oxygen exposure without fragmenting, which would create debris near the ISS. In the end, only a select number of the team’s materials made the cut.

The MISSE-22 testbed holds multiple experimental polymers. Instead of standard illumination, the team constructed a custom on-orbit polariscope: LEDs beneath each sample shine polarized light up through the material. A small camera system then slides over the top to capture these highly specific optical changes on a set schedule over the course of several months in space.

Using Light to Reveal Space Strain

Using polarized light and machine learning to rapidly analyze color patterns in the images they receive from orbit, the researchers can track how stress inside each sample changes over time. Periodically, the system will cycle through the materials, and the images will be downlinked to Earth.

When the extended mission ends and the samples return, the team will compare those in-orbit measurements with detailed lab tests on the actual pieces that flew. Without returned materials, they would only have images and sensor data to work from. By testing the same samples in the lab, they can check how accurate the remote measurements really are and refine their methods.

If the materials perform as expected, the results could help engineers design satellites that last longer in orbit without carrying so much protective weight —providing a significant technological advantage in space domain awareness and asset longevity.

Learn more at space.gatech.edu.

As during previous editions, this year’s conference featured more than two dozen scientists, engineers, policy experts, and thought leaders from Georgia Tech and beyond, illustrating how collaboration across fields – from science and engineering to public policy and international affairs – helps to advance strategic research priorities. 

“Frontiers is about discovery and connections across disciplines and generations,” says Susan Lozier, dean of the College of Sciences and Betsy Middleton and John Clark Sutherland Chair. “This edition provided an inspiring glimpse into the future of space exploration and the many ways Georgia Tech is contributing to research and missions seeking answers to what lies beyond our planet.” 

Commitment to Space

Space research is a key institutional priority at Georgia Tech, which is home to numerous academic and research programs in planetary sciences, robotics, mission design, space policy, and other areas. 

The recently established Space Research Institute (SRI) serves as the central hub connecting the broad range of space-related research across campus. Led by Jud Ready, who also serves as principal research engineer at the Georgia Tech Research Institute, SRI has expanded support for space research and commercialization through initiatives such as the CreationsVC Space Fellows Program and Centers, Programs, and Initiatives seed grant program.

SRI’s efforts are in line with Georgia Tech’s long-standing contribution to space exploration. Hundreds of Yellow Jacket alumni work in the space sector, including several graduates who are playing key roles in the Artemis program. To date, more than a dozen Georgia Tech alumni have traveled to space.

Exploring the Final Frontier

The conference featured a series of panels and discussions led by faculty and researchers from the Colleges of Sciences and Engineering as well as the Ivan Allen College of Liberal Arts. 

Sessions explored how researchers are studying the processes and conditions that support planetary habitability, seeking to answer one of humanity’s greatest questions: Does life exist beyond Earth? Speakers also examined how analog fieldwork in Earth’s extreme environments can inform space exploration, and how space research, in turn, can deepen our understanding of our own world.

Additional conversations centered on building better space missions through improved understanding of team and individual resilience, data collection, navigation, and the development of advanced technologies like the robots developed through the NASA LASSIE Project. 

Frontiers also highlighted Georgia Tech’s commitment to preparing the next generation of space scientists, engineers, and leaders. Student training and engagement were recurring themes throughout the day, with speakers emphasizing opportunities for student-led and student-run missions and research. A panel of Georgia Tech alumni shared their own STEM career journeys, challenging the idea of “one right path” to success — and acknowledging the resources and opportunities available at the Institute. 

A highlight of the conference was a fireside chat with Atlanta-native, retired U.S. Army Colonel and NASA Astronaut R. Shane Kimbrough (M.S. Operations Research 1998). Kimbrough, who spent a total of 388 days in space and performed nine spacewalks across three missions, reflected on his career and the evolution of spaceflight. He emphasized the expanding role of public-private and international partnerships in advancing ambitious goals, such as creating a permanent human outpost on the Moon. 

Policy and Public

The conference also explored how policy influences space discovery and innovation, with discussions touching on such issues as space security, access, governance, sustainability — and the influence of technology and science fiction on public perception and policy. 

Panelists described current policy frameworks governing outer space as struggling to keep pace with rapidly advancing technologies and expanding activities. According to these experts, increasing tensions among commercial, research, and recreational uses of space call for greater coordination among private and government entities to balance competing priorities while maximizing opportunities for innovation and exploration. 

The conference was punctuated by a networking lunch connecting attendees with Atlanta’s public astronomy community – including partners at several universities and the Georgia Tech Astronomy Club, which set up telescopes for attendees to safely observe the sun. Later that evening, the Georgia Tech Observatory hosted its Public Night, welcoming the broader Atlanta community to campus for telescope views of Jupiter, the Orion Nebula, and other celestial bodies. 

The Observatory Night was a fitting conclusion to a full day focused on Georgia Tech’s commitment and contributions to inspiring future generations of space explorers through research, education, and outreach.

Published today in the journal Nature Communications, the paper “Trivalent Titanium in High-Titanium Lunar Ilmenite” confirms titanium in a reduced, trivalent state in a black, metal-rich lunar mineral called ilmenite. It’s a state only possible in low-oxygen environments, conditions researchers refer to as “reducing.”

“Models have suggested that these reducing conditions may have varied at different locations and times across the surface of the Moon,” says lead author Advik Vira, a graduate student in the School of Physics who recently earned his doctoral degree. “We hope our microscopy technique can be a valuable step in mapping and understanding the Moon’s 4.5-billion-year history.”

The team anticipates that their technique could be used on many of the lunar samples collected more than 50 years ago by the Apollo missions in addition to the Apollo Next Generation Samples — a group of lunar samples that have been stored under pristine conditions — and new samples from the planned Artemis missions, with Artemis II slated for launch this spring. The technique might also be applicable to samples collected from the far side of the Moon and returned in 2024 by the Chang’e-6 mission.

“The Moon holds clues not only to its own past, but also to the earliest eras of Earth’s evolution — history that has long since been erased from our planet,” Vira says. “This study is a step toward understanding the history of both and a reminder that there is still so much left to learn from the lunar rocks we’ve brought back to Earth.”

The School of Physics research team included corresponding authors Vira and Professor Phillip First; in addition to graduate student Roshan Trivedi; undergraduate students Gabriella Dotson, Keyes Eames, Dean Kim, and Emma Livernois; and Professor Zhigang Jiang, along with Institute for Matter and Systems Materials Characterization Facility Senior Research Scientist Mengkun Tian; School of Chemistry and Biochemistry Senior Research Scientist Brant Jones and Thom Orlando, Regents' Professor in the School of Chemistry and Biochemistry with a joint appointment in the School of Physics. 

The Georgia Tech team was joined by Addis Energy Senior Geochemist Katherine Burgess; Macalester College Assistant Professor of Geology Emily First; along with Lawrence Berkeley National Laboratory Research Scientist Harrison Lisabeth, Senior Scientist Nobumichi Tamura, and Postdoctoral Fellow Tyler Farr, who recently earned a Ph.D. from Georgia Tech’s George W. Woodruff School of Mechanical Engineering.

CLEVER research

The investigation began with a dark gray rock called a lunar basalt. Formed when ancient magma erupted on the Moon’s surface, minerals crystallized as it cooled — preserving key information in their structures. Billions of years later, the rock was brought to Earth by the 1972 Apollo 17 mission, where a small piece is now stored at Georgia Tech’s Center for Lunar Environment and Volatile Exploration Research (CLEVER), a NASA Solar System Exploration Research Virtual Institute (SSERVI) center led by Orlando.

As a NASA virtual institute, CLEVER supports researchers exploring lunar conditions and developing tools for the upcoming crewed Artemis missions, and provided the lunar samples for this research. The SSERVI also plays a critical role in training the next generation of planetary researchers: both Vira and Farr earned their Ph.D.s while on the CLEVER team.

“At CLEVER, we are very interested in understanding the impacts of space weathering,” Vira says. “We implemented modern sample preparation and advanced microscopy techniques to image samples at the atomic level, and were curious to apply it more broadly to the collection of Apollo rocks in the Orlando Lab. This sample caught our attention.”

“When we imaged an ilmenite crystal from the lunar basalt, what struck us first was how uniform and perfect the crystal structure was,” he recalls. “We found no defects from space weathering and instead saw an undamaged, pristine crystal — undisturbed for 3.8 billion years.”

To investigate further, the team analyzed small chips of the rock with Burgess, a member of the RISE2 SSERVI team and then a geologist at the U.S. Naval Research Laboratory. Using state-of-the-art electron microscopy and spectroscopy techniques, Vira determined the oxidation state of the elements in the ilmenite present. 

In spectroscopy measurements, each element leaves a distinct ‘signature,’ Vira explains. “When we brought our results back to Georgia Tech’s Materials Characterization Facility, Mengkun (Tian) noticed something unusual: the signature showed titanium might be present in the trivalent state.”

The presence of trivalent titanium had long been suspected in this lunar mineral. The team was intrigued. 

A new window into old rocks

With funding from Georgia Tech’s Center for Space Technology and Research (CSTAR), Vira returned to the U.S. Naval Research Laboratory to analyze additional samples. The results confirmed that more titanium was present than the mineral’s formula (FeTiO₃) predicts — indicating a portion of the titanium present was trivalent.

“That led me to place our measurements in terms of the broader geological context,” Vira shares. Working with First, Vira explored how ilmenite with trivalent titanium could help reconstruct the nature of ancient magmas from the Moon, especially the chemical availability of oxygen.

“Because its location on the Moon was noted during the Apollo mission, we know exactly where this rock is from, and we can determine how old the rock is,” he explains. “When coupled with our trivalent titanium measurements, we can use that information to estimate the reducing conditions for this specific region at the specific time our rock formed.”

If the upcoming Artemis missions return samples suitable for the team’s technique, these rocks could provide a new window into ancient lunar geology. The research also highlights that many lunar samples already on Earth could be reexamined to look for trivalent titanium.

“There is still so much to learn from the lunar samples we have already brought to Earth,” Vira says. “It’s a testament to the long-term value of each sample return mission. As technology continues to advance, this type of work will continue to give us critical insights into our planet and our place in the universe for years to come.”

So, what do you do if you want to design robots and their controlling algorithms for future moon visits? If you’re Yashwanth Nakka, you bring the moon to you.

Nakka has recreated the moon in a research lab at Georgia Tech, hauling in seven tons of basalt rock to mimic the look and feel of the lunar surface. With dark black walls and a bright light that simulates the sun’s glare, the Aerospace Robotics Lab (ARL) is the only one of its kind in a university setting.

This lab will help Nakka’s team of researchers understand how robotic rovers interact with the environment on the moon — how they perceive the terrain in different sunlight conditions, for example, and how they navigate across a surface that can easily swallow a rover wheel. 

“From a research perspective, many of today’s space mobility solutions still build upon algorithms developed two decades ago. This new lab positions us to pioneer the next generation of autonomous mobility technologies that can overcome unstructured terrain, environmental, and operational challenges. Advancing autonomous systems is critical to enabling deep-space exploration, supporting resource utilization, and empowering scientists to investigate new frontiers such as icy moons that may harbor subsurface oceans,” said Nakka, assistant professor in the Daniel Guggenheim School of Aerospace Engineering.

Unlike the Moon’s ultra-fine, clingy regolith that can coat equipment and cause severe wear and damage, Nakka’s lab uses carefully selected, gem-sized basalt rocks. This material allows researchers to realistically study how robots interact with granular terrain while avoiding the need for extensive protective equipment, making experimentation safer, more efficient, and easier to conduct. When robots are driving on the surface, they experience the same shifts and movements they would in the moondust.

The SRI builds upon Georgia Tech’s long and distinguished history in space research and exploration. By uniting experts across disciplines — from aerospace engineering to planetary science, astrophysics, robotics, policy, the arts, and origin of life explorations — the SRI aims to create a resilient ecosystem for space research that can adapt and thrive, even in an era of fiscal uncertainty. It is composed of faculty, staff, and students whose collaborative research spans a broad spectrum of space-related topics, all deeply connected to advancing our understanding of space and its impact on the human experience.

“The launch of the SRI comes at a pivotal moment for the scientific community,” said Vice President of Interdisciplinary Research Julia Kubanek. “As the federal government proposes major cuts to funding agencies, our interdisciplinary research institutes are striving to support faculty and make them more competitive across disciplinary boundaries. This institute will publicly showcase impactful research led by Georgia Tech faculty, attract new collaborators, and pursue alternative funding strategies via philanthropic and industry partners.”

The Space Research Institute will consist of an interdisciplinary community of faculty across Georgia Tech’s schools, colleges, and the Georgia Tech Research Institute (GTRI). 

“It is an honor to be appointed executive director of the Space Research Institute,” said Ready. “My plan is to provide internal and external space researchers with access to Georgia Tech’s world class facilities and turbocharge the space activities already underway. We’re committed to empowering our existing community while forging new partnerships that will expand our reach and impact across the global space ecosystem.”

Ready, a principal research engineer in GTRI’s Electro-Optical Systems Laboratory, is the first GTRI faculty member to serve in a long-term capacity as an IRI executive director. Prior to his appointment, he served as associate director of external engagement for the Georgia Tech Institute for Matter and Systems and director of the Georgia Tech Center for Space Technology and Research (CSTAR). He is also an adjunct professor in the School of Materials Science and Engineering at Georgia Tech.

Before joining the Georgia Tech faculty, Ready worked for General Dynamics and MicroCoating Technologies. Throughout his career, he has served as PI or co-PI for grants totaling more than $25M awarded by the Army, Navy, Air Force, DARPA, NASA, NSF, NIST, DOE, other federal sponsors, industry, charitable foundations, private citizens, and the States of Georgia and Florida. His current research focuses primarily on energy capture, storage, and delivery enabled by nanomaterial design. His research has been included on three missions to the International Space Station, two others to low earth orbit, and one perpetually in heliocentric orbit (Lunar Flashlight). His future space missions include MISSE-21 to the International Space Station and SSTEF-1 to the Lunar surface. A half dozen solar cells from his past missions to the International Space Station will be included in the permanent At Home in Space exhibit opening on the Smithsonian National Air and Space Museum's 50th Anniversary.

Ready has received numerous awards and honors for his work. His most recent awards include the Class of 1934 Outstanding Innovative Use of Education Technology award in 2025 and the Outstanding Achievement in Research Program Development award in 2023, both from Georgia Tech. He also received the One GTRI Collaboration Award in 2022, which he was awarded during GTRI’s annual Distinguished Performance Awards celebration.

Founder, Georgia Tech Center for Distributed Energy 

Deepakraj “Deepak” Divan is a globally recognized innovator in power electronics and grid transformation. He was awarded the IEEE Medal in Power Engineering in 2024.

He holds over 85 U.S. and international patents and has authored 400 refereed publications. His pioneering work on soft‑switching converters—integral for efficient energy storage, EV charging, and industrial controls—has spurred a global $70 billion power electronics industry.  

Divan laid the groundwork for grid‑forming inverter control, enabling high-renewables integration. He is the co-author of Energy 2040: Aligning Innovation, Economics and Decarbonization, named by Forbes as one of the “10 Essential Books and Podcasts Every Leader Needs in 2025”. 

“Being named an NAI Fellow is a tremendous honor,” said Divan. “It reflects years of effort to rethink how electricity is delivered and managed to solve real problems and to drive practical innovations that matter.” 

 As the founder of Georgia Tech’s Center for Distributed Energy, he led research that transforms electricity delivery through analytics, monitoring, and optimization.  

An entrepreneur, Divan co-founded Varentec (backed by Bill Gates and Khosla Ventures) and seeded ventures including GridBlock, Soft Switching Technologies, Innovolt, and Smart Wires—raising over $500 million. A National Academy of Engineering member and IEEE Fellow, he champions scalable energy-access solutions worldwide.

Inspired by SpaceX’s Super Heavy booster, a team led by Georgia Tech’s Spencer Bryngelson and New York University’s Florian Schäfer modeled the turbulent interactions of a 33-engine rocket. Their experiment set new records, running the largest ever fluid dynamics simulation by a factor of 20 and the fastest by over a factor of four.

The team ran its custom software on the world’s two fastest supercomputers, as well as the eighth fastest, to construct such a massive model.

Applications from the simulation reach beyond rocket science. The same computing methods can model fluid mechanics in aerospace, medicine, energy, and other fields. At the same time, the work advances understanding of the current limits and future potential of computing. 

The team finished as runners-up for the 2025 Gordon Bell Prize for its impactful, multi-domain research. Referred to as the Nobel Prize of supercomputing, the award was presented at the world’s top conference for high-performance computing (HPC) research.

“Fluid dynamics problems of this style, with shocks, turbulence, different interacting fluids, and so on, are a scientific mainstay that marshals our largest supercomputers,” said Bryngelson, an assistant professor with the School of Computational Science and Engineering (CSE).

“Larger and faster simulations that enable solutions to long-standing scientific problems, like the rocket propulsion problem, are always needed. With our work, perhaps we took a big dent out of that issue.”

The Super Heavy booster reflects the space industry’s move toward reusable multi-engine first-stage rockets that are easier to transport and more economical overall. 

However, this shift creates research and testing challenges for new designs.

Each of Super Heavy’s 33 thrusters expels propellant at ten times the speed of sound. As individual engines reach extreme temperatures, pressures, and densities, their combined interactions with the airframe make such violent physics even more unpredictable.

Frequent physical experiments would be expensive and risky, so scientists rely on computer models to supplement the engineering process. 

Bryngelson’s flagship Multicomponent Flow Code (MFC) software anchored the experiment. MFC is an open-source computer program that simulates fluid dynamic models. Bryngelson’s lab has been modifying MFC since 2022 to run on more powerful computers and solve larger problems. 

In computing terms, this MFC-enhanced model simulated fluid flow resolution at 200 trillion grid points and one quadrillion degrees of freedom. These metrics exceeded previous record-setting benchmarks that tallied 10 trillion and 30 trillion grid points.

This means MFC simulations provide greater detail and capture smaller-scale features than previous approaches. The rocket simulation also ran four times faster and achieved 5.7 times the energy efficiency of comparable methods.   

Integrating information geometric regularization (IGR) into MFC played a key role in attaining these results. This new approach improved the simulation’s computational efficiency and overcame the challenge of shock dynamics.

In fluid mechanics, shock waves occur when objects move faster than the speed of sound. Along with hampering the performance of airframes and propulsion systems, shocks have historically been difficult to simulate.

Computational scientists have used empirical models based on artificial viscosity to account for shocks. Although these approaches mimic the physical effects of shock waves at the microscopic scale, they struggle to effectively capture the large-scale features of the flow. 

Information geometry uses curved spaces to study concepts of statistics and information. IGR uses these tools to modify the underlying geometry in fluid dynamics equations. When traveling in the modified geometry, fluid in the model preserves the shocks in a more natural way. 

“When regularizing shocks to much larger scales relevant in these numerical simulations, conventional methods smear out important fine-scale details,” said Schäfer, an assistant professor at NYU’s Courant Institute of Mathematical Sciences.

“IGR introduces ideas from abstract math to CFD that allow creating modified paths that approach the singularity without ever reaching it. In the resulting fluid flow, shocks never become too spiky in simulations, but the fine-scale details do not smear out either.” 

Simulating a model this large required the Georgia Tech researchers to run MFC on El Capitan and Frontier, the world's two fastest supercomputers. 

The systems are two of four exascale machines in existence. This means they can solve at least one quintillion (“1” followed by 18 zeros) calculations per second. If a person completed a simple math calculation every second, it would take that person about 30 billion years to reach one quintillion operations.

Frontier is housed at Oak Ridge National Laboratory and debuted as the world’s first exascale supercomputer in 2022. El Capitan surpassed Frontier when Lawrence Livermore National Laboratory launched it in 2024.

To prepare MFC for performance on these machines, Bryngelson’s lab followed a methodical approach spanning years of hardware acquisition and software engineering. 

In 2022, Bryngelson attained an AMD MI210 GPU accelerator. Optimizing MFC on the component played a critical step toward preparing the software for exascale machines.

AMD hardware underpins both El Capitan and Frontier. The MI300A GPU powers El Capitan while Frontier uses the MI250X GPU. 

After configuring MFC on the MI210 GPU, Bryngelson’s lab ran the software on Frontier for the first time during a 2023 hackathon. This confirmed the code was ready for full-scale deployment on exascale supercomputers based on AMD hardware. 

In addition to El Capitan and Frontier, the simulation ran on Alps, the world’s eight-fastest supercomputer based at the Swiss National Supercomputing Centre. It is the largest available system that features the NVIDIA GH200 Grace Hopper Superchip.

Like with AMD GPUs, Bryngelson acquired four GH200s in 2024 and began configuring MFC to the latest hardware innovation powering New Age supercomputers. Later that year, the Jülich Research Centre accepted Bryngelson’s group into an early access program to test JUPITER, a developing supercomputer based on the NVIDIA superchip.

The group earned a certificate for scaling efficiency and node performance on the way toward validating that their code worked on the GH200. The early access project proved successful for JUPITER, which launched in 2025 as Europe’s fastest supercomputer and fourth fastest in the world.

“Getting the level of hands-on experience with world-leading supercomputers and computing resources at Georgia Tech through this project has been a fantastic opportunity for a grad student,” said CSE Ph.D. student Ben Wilfong.

“To leverage these machines, I learned more advanced programming techniques that I’m glad to have in my tool belt for future projects. I also enjoyed the opportunity to work closely with and learn from industry experts from NVIDIA, AMD, and HPE/Cray.”

El Capitan, Frontier, JUPITER, and Alps maintained their rankings at the 2025 International Conference for High Performance Computing Networking, Storage and Analysis (SC25). Of note, the TOP500 announced at SC25 that JUPITER surpassed the exaflop threshold. 

The SC Conference Series is one of two venues where the TOP500 announces updated supercomputer rankings every June and November. The TOP500 ranks and details the 500 most powerful supercomputers in the world. 

The SC Conference Series serves as the venue where the Association for Computing Machinery (ACM) presents the Gordon Bell Prize. The annual award recognizes achievement in HPC research and application. The Tech-led team was among eight finalists for this year’s award.

Along with Bryngelson, Georgia Tech members included Ph.D. students Anand Radhakrishnan and Wilfong, postdoctoral researcher Daniel Vickers, alumnus Henry Le Berre (CS 2025), and undergraduate student Tanush Prathi.

Schäfer’s partnership with the group stems from his previous role as an assistant professor at Georgia Tech from 2021 to 2025. 

Collaborators on the project included Nikolaos Tselepidis and Benedikt Dorschner from NVIDIA, Reuben Budiardja from ORNL, Brian Cornille from AMD, and Stephen Abbot from HPE. All were co-authors of the paper and named finalists for the Gordon Bell Prize. 

“I’m elated that we have been nominated for such a prestigious award. It wouldn't have been possible without the combined and diligent efforts of our team,” Radhakrishnan said. 

“I’m looking forward to presenting our work at SC25 and connecting with other researchers and fellow finalists while showcasing seminal work in the field of computing.”

Following a nationwide search, Georgia Tech President Ángel Cabrera has named Timothy Lieuwen the Executive Vice President for Research (EVPR). Lieuwen has served as interim EVPR since September 10, 2024. 

Modern warfare and the technology behind it are evolving. Around the world, the skies are increasingly filled with small, agile, and intelligent systems — drones, missiles, and interceptors that demand lightweight, affordable, and highly efficient propulsion. The future of defense is fast, adaptable, and precise — and Georgia is positioning itself at the center of that transformation. 

Tech College of Engineering alumni Chad Pozarycki, Ph.D., CHBE, 2022, and José Andrade, AE, 2025, are on a mission to make biochemical monitoring more accessible — with a focus on preventing disease. Today, their startup Deleon, using NASA’s technology (originally designed to search for life on Mars) and metabolomics, provides a system that uses daily urine sampling to track metabolites related to overtraining, stress, and recovery. Future applications will be aimed at early disease detection.

“Something that frustrated me about metabolomics was its lack of focus on preventive care,” said Andrade. “We created Deleon by combining these ideas and tracking the human metabolome to optimize for healthy lifestyles.”

The Deleon founders began the company shortly after Pozarycki completed his graduate studies at Georgia Tech, with Andrade moonlighting and Pozarycki working a part-time job at Georgia Tech’s bike shop to keep the project afloat. In the beginning, funding was a major challenge. 

“I finished my Ph.D., was working on Deleon, and didn’t have any income. CREATE-X gave us $5,000 in funding, which motivated us to keep going on this project,” said Pozarycki.

CREATE-X, Georgia Tech’s campus-wide initiative to instill entrepreneurial confidence and help students launch startups, provided more than funding. Through the program, Deleon received guidance on finding potential customers. 

“The one-on-one advice from expert CREATE-X entrepreneurs and organizers like Rahul [CREATE-X director] and Margaret [LAUNCH associate director] was super valuable and helped us focus on launching our minimum viable product and getting our first customers,” said Andrade.

The program’s culminating event, Demo Day, gave Deleon a platform to present to investors and the public. Among dozens of student-led startups, Deleon’s data-driven approach attracted strong interest. The exposure led to an eventual $850,000 investment, partially funded by Georgia Tech's early-stage fund, GTF Ventures. This investment allowed the founders to work full-time on the company, hire a team, and build a lab space.

“I would recommend the CREATE-X program to anyone,” Pozarycki said. “Even if you don’t think you want to start a company, there’s a lot you can learn about commercialization in this program that may change your mind and give you more control over your own fate.”

Deleon’s path from concept to launch highlights the growing role of Georgia Tech’s entrepreneurial ecosystem in supporting student innovation. Programs like CREATE-X not only help students build companies but also contribute to regional economic growth by keeping talent and investment in the Southeast.

“CREATE-X is the best environment on campus to learn by doing,” Pozarycki said. “You are encouraged to build something real, not just talk about it. You’ll leave knowing how to talk to customers, how to pitch, and how to think like a founder.”

Opportunities for Entrepreneurs

Students, faculty, researchers, and alumni interested in developing their own startups are encouraged to apply to CREATE-X’s Startup Launch. The early admission deadline to apply for Startup Launch is Nov. 17. Spots are limited. Apply now for a higher chance of acceptance and early feedback.

Simon’s research team has been awarded $1.4 million through NASA’s Precursor Science Investigations for Europa (PSI-E) program. Their project is one of seven selected to provide essential insights that, according to the program announcement, “will maximize the science return during the radiation-limited lifetime of the Europa Clipper.” 

Simon also serves as the institutional lead co-investigator of a second $1.4 million project, led by researchers at the University of California, Berkeley, which seeks to decipher how Europa's atmosphere and ionosphere contribute to the magnetic field near the moon. This project was selected during the same call for proposals.

“The research award is a fantastic opportunity to contribute to a mission centered on Europa’s complex plasma and electromagnetic environment,” says Simon, referencing the Georgia-Tech led proposal. “Our project combines foundational plasma physics from our School of Physics and geophysical knowledge from our School of Earth and Atmospheric Sciences to understand how the magnetic field near Europa is affected by the plasma populating Jupiter’s environment.”

The research team includes Earth and Atmospheric Sciences Ph.D. students Ariel Tello Fallau and Charles Michael Haynes. Neil Baker, a Ph.D. student in the School of Physics, is contributing to the Berkeley-led PSI-E project that also includes Georgia Tech alumnus Lucas Liuzzo (Ph.D. EAS 2018), now an assistant research scientist at the University of California, Berkeley’s Space Sciences Laboratory. 

Groundwork for discovery

With a radius of only 1,560 kilometers, Europa is one of Jupiter’s four largest moons, known as the Galilean moons, discovered by Italian astronomer Galileo Galilei in the 1600s.

More than two decades ago, data from NASA’s Galileo mission — specifically magnetic field measurements collected far above Europa’s surface — pointed to the existence of a global subsurface ocean. This ocean, which may contain more liquid water than all of the Earth’s oceans combined, has made Europa a prime candidate in the search for life beyond Planet Earth.

“Finding evidence of a saltwater ocean lurking beneath Europa’s surface was a serendipitous discovery during the Galileo mission,” Simon explains. “NASA’s Europa Clipper mission picks up where the Galileo mission left off.” 

Launched in October 2024, the Europa Clipper space probe is expected to reach Jupiter’s orbit in 2030. That gives Simon and his team only a few years to complete their analysis. 

“Our research is doing the preparatory work to determine what and where we can measure further magnetic evidence of the ocean beneath Europa’s surface,” says Simon. “When the spacecraft arrives, we will find out whether our predictions are correct.”

Using advanced computer simulations, the team aims to better understand the magnetic fields near Europa. Part of these fields is generated by electric currents in the moon’s saltwater ocean; the other part is created by fast-moving flows of plasma — ionized matter that fills much of space — as it interacts with Europa’s atmosphere and surface.  

“Our project focuses on how the magnetic fields from plasma flow patterns compete with the magnetic signal from Europa’s ocean,” says Simon. “We want to determine which part of the magnetic field near Europa originates from the ocean and which part is a disruptive effect from the plasma.”

Deciphering these magnetic signals will provide essential context for interpreting Europa Clipper’s measurements, helping to not only confirm the ocean’s existence but also reveal details about its structure.

“Paul Sell is a wonderful addition to our College of Sciences community,” says Susan Lozier, dean of the College of Sciences, Betsy Middleton and John Clark Sutherland Chair, and professor in the School of Earth and Atmospheric Sciences. “His leadership brings renewed energy to the Georgia Tech Observatory, and I look forward to seeing how he expands its impact across campus and in the broader community.”

Observing the cosmos from campus

The Georgia Tech Observatory was established nearly two decades ago at a time when the Institute’s astronomy and astrophysics research and teaching ecosystem was in its infancy. 

School of Physics Principal Academic Professional Emeritus Jim Sowell created the facility on the roof of the Howey Physics Building in 2007 and served as its director until his retirement in 2024. 

“The Observatory — and its numerous variety of telescopes — makes it possible for Georgia Tech students and Atlanta-area visitors to see with their own eyes some of the best, awe-inspiring celestial delights, including craters on the Moon, Jupiter’s Red Spot, Saturn’s rings, and many other objects,” says Sowell.

The Observatory’s primary instrument is a 20-inch diameter telescope by Officina Stellare. Known as the Georgia Tech’s Space Object Research Telescope (GT-SORT), this Raven-class space surveillance telescope is used by researchers in the Daniel Guggenheim School of Aerospace Engineering to monitor man-made spacecraft.

“What’s unique about the Georgia Tech Observatory is that it’s right on campus, offering a meaningful, hands-on experience to everyone,” explains Sell. “It can be readily integrated into experiential learning projects on campus all year round.”

Sell’s upper-level astronomy lab, which combines lectures with experiences at the Observatory, highlights the facility’s academic importance.

Yet, the Observatory’s impact extends beyond the classroom, thanks to free community events like “Public Nights at the Observatory,” which offer attendees the opportunity to explore the night sky. 

Held most months, weather permitting, this event features telescopes stationed outside the Howey Physics Building, allowing astronomy enthusiasts from Georgia Tech and beyond to view the Moon, Jupiter, Saturn, and other cosmic wonders. These gatherings typically draw more than 100 stargazers.

Specialized groups are also hosted at the Observatory. For example, the Georgia Tech Astronomy Club uses the facility during its weekly meetings.

“The Observatory is a haven where students can step outside for a moment and get lost in the stars,” says AJ Chadha, club president and fourth-year computer science major. “With one of the largest telescopes in Georgia, the on-campus 20-inch GT-SORT, we weave astronomy directly into student life.”

Under Sell’s leadership, the Observatory will continue to strengthen partnerships with student organizations, campus units, and community groups.

“I'm excited to explore additional ways we can use this resource for outreach and academic purposes that benefit both Georgia Tech and the Atlanta community,” Sell adds.

A passion for astronomy

Before joining Georgia Tech, Sell served as senior lecturer, astronomy undergraduate coordinator, and interim director of the teaching observatory at the University of Florida. 

His passion for astronomy began at an early age, sparked by a gift from his parents: an Orion refracting lens telescope.

“I remember taking out that telescope, even in freezing cold Ohio winters, simply because the observing conditions were better,” he recalls.

Sell nurtured his interest in astronomy through his university studies and extracurricular activities, which included working in planetaria as an undergraduate at the University of Toledo. He later obtained a Ph.D. in Astronomy from the University of Wisconsin-Madison.

“I am grateful for the opportunity to share my passion for astronomy, not only with our physics students but with the larger Georgia Tech community — through classroom lectures, student advising, and Observatory outreach,” Sell says.

On September 5, more than 130 space researchers gathered for the Space Research Institute’s (SRI) inaugural meeting, held in the Marcus Nanotechnology Building. The event drew a standing-room-only crowd, with attendees from across all of Georgia Tech’s colleges. This marked the SRI’s first major convening since its launch on July 1, offering a platform to discuss its vision and bring Georgia Tech’s space research efforts into closer conversation.

Georgia Tech’s Office of Commercialization’s new Quadrant-i unit focuses on the commercialization of Georgia Tech intellectual property. In combination with Georgia Tech’s consistently top-ranked Daniel Guggenheim School of Aerospace Engineering and its newly formed interdisciplinary Space Research Institute (SRI), Quadrant-i is positioned to dramatically boost the output of space-related spin-offs into a burgeoning Atlanta startup ecosystem. A strategic gift from CreationsVC will support these efforts by creating a pilot program that provides funding for the startup projects of five CreationsVC Fellows per year for three years.

CreationsVC is a venture capital firm that specializes in investing in space tech, AI, and related technologies. CreationsVC sponsors Creation-Space, an Israeli-based global innovation hub that is fostering innovation to enable humanity’s expansion beyond Earth. Steve Braverman, who heads CreationsVC, said the gift is focused on "identifying innovative technologies that support research on life in space, combined with a focus on climate efficiency. This will help improve both expansion of space-centric industry as well as efforts that address challenges on Earth.” 

Braverman said he was attracted to Georgia Tech’s focus on entrepreneurship and its track record in aerospace innovation. “I am impressed with the depth and breadth of technical expertise and energized by the passionate commitment of faculty and students to see their innovations have real-world impact. This gift is intended to supercharge efforts over the next three years to launch several startups that can grow quickly and have impact in Atlanta and Israel.”

Quadrant-i has worked closely with the SRI in its formation and made space commercialization an important and embedded pillar of the new activity. “We are thrilled to work with Steve and the CreationsVC team in identifying and accelerating nascent technologies that will have dual-use value propositions in space, climate, and AI applications,” said Quadrant-i’s director Jonathan Goldman. “We have a fantastic well of innovation from our faculty and graduate students and an amazing fountain of entrepreneurial talent from our CREATE-X program for our undergrads. We are excited to see this relationship blossom.” 

“This facility demonstrates Georgia Tech’s long-term commitment to pioneering the technologies that will shape the future of aviation,” said Ángel Cabrera, president of Georgia Tech. “Aerospace products are Georgia’s No. 1 export, and the Institute’s top-ranked Guggenheim School produces some of the nation’s top aerospace engineering talent. With this advanced laboratory, we’re making strategic investments that will grow our state’s and our Institute’s national leadership in aerospace innovation and advanced manufacturing.” 

The 10,000-square-foot facility, located in Georgia Tech’s North Avenue Research Area, has been purpose-built to accelerate innovation in electric and hybrid-electric aircraft propulsion as well as autonomous flight systems. Designed as a hands-on research and teaching environment, the Aircraft Prototyping Laboratory includes a suite of specialized laboratories: an electric powertrain lab, a propulsion system test cell, an avionics lab, a composites fabrication area, and a high-bay integration space capable of housing prototype aircraft with wingspans up to 20 feet.  

One of the facility’s first major projects is RAVEN (Research Aircraft for eVTOL Enabling techNologies), a collaboration with NASA to design, build, and fly an electric vertical takeoff and landing (eVTOL) research aircraft in the 1,000-pound weight class. The aircraft will serve as a research platform for electric propulsion reliability, flight controls, noise reduction, and autonomy. Systems integration and test activities for RAVEN will take place within the new lab, underscoring the facility’s central role in shaping the national agenda for advanced air mobility. 

“The Aircraft Prototyping Laboratory is the centerpiece of an ecosystem of flight research that we are building at Georgia Tech, focused on eVTOLs, drones, and other advanced air vehicles,” said Brian German, professor of aerospace engineering at Georgia Tech. “We greatly appreciate the long-term partnership we’ve had with NASA in the development of RAVEN, and we’ve designed the facility specifically to support RAVEN and aircraft of a similar scale.”  

Other projects underway in the Aircraft Prototyping Laboratory include a solar-electric aircraft demonstrator and SETTER, a subscale eVTOL testbed focused on developing software for safety-critical applications. These projects support Georgia Tech’s expanding ecosystem for flight testing and research, including collaborations with regional test facilities in the metro Atlanta area. 

“These projects exemplify our commitment to advancing the technologies that will define the future of flight. Powered by the ingenuity of our faculty and students, the Aircraft Prototyping Laboratory ensures that Georgia Tech and the state of Georgia remain leaders in aerospace innovation and economic development,” said Mitchell Walker, William R.T. Oakes Professor and chair of the Daniel Guggenheim School of Aerospace Engineering.

Through the Aircraft Prototyping Laboratory, Georgia Tech continues to develop research in electric and autonomous aircraft, supporting both the Institute’s and Georgia’s role in the aerospace industry. The school educates more than 2,000 aerospace students and is ranked No. 1 among public universities for aerospace engineering. 

Since 1989, Georgia Tech has successfully managed GSGC, a statewide network of higher education institutions, nonprofits, strategic industry allies, and partners who develop and administer STEM programs. Established in 1988 by Congress and implemented by NASA, GSGC has grown into a powerful source for STEM innovation and opportunity. 

Each year, GSGC receives federal funding to support a wide range of programs, including fellowships and scholarships for college students, research initiatives, internships, hands-on STEM activities for K-12 students, professional development for educators, and workforce development programs. 

Initially, there were only four affiliate institutions: Clark Atlanta University, Georgia State University, Tuskegee University, and Kennesaw State University. Today, that number has grown to more than 21 affiliate institutions and an additional six partner organizations. Affiliates are elected to membership and actively advance the program’s mission through the financial support of GSGC.

Wang, who is a Ph.D. student in the School of Mathematics and a master’s student in the Daniel Guggenheim School of Aerospace Engineering, will focus on developing mathematically-backed landing solutions for spacecraft. 

“I first became interested in powered descent problems during my Fall 2024 internship with NASA’s Human Landing System at Marshall Space Flight Center,” he says. “With my mathematical background in optimization and topology, and my passion for space exploration, I saw this research topic as a perfect fit when my co-advisor Dr. Panagiotis Tsiotras suggested it.”

Wang is co-advised by School of Mathematics Professor and Hubbard Research Fellow John Etnyre alongside Panagiotis Tsiotras, who holds the David and Andrew Lewis Endowed Chair in the Daniel Guggenheim School of Aerospace Engineering and is also associate director at the Institute for Robotics and Intelligent Machines.

In addition to his Georgia Tech advisors, Wang will collaborate with a NASA Subject Matter Expert, who will connect him with the larger technical community. He will perform part of the research as a visiting technologist at multiple NASA centers, giving him the opportunity to work with leading engineers and scientists and share his research results directly with the NASA community.

From abstractions to space exploration

“NASA’s upcoming missions to the Moon, Mars, and beyond need technology that allows spacecraft to land precisely at their intended sites,” says Wang. “My research will focus on the last stage of landing, called powered descent. This stage powers up engines, which guide the spacecraft into a safe landing using a pre-designed trajectory that autopilot follows.”

This means that researchers need to figure out the correct thrust, direction, and timing to reach a landing spot — all while navigating a landing that uses as little fuel as possible.

“A common approach is to treat this as an optimization problem: minimizing fuel consumption with rigid-body physics as constraints to determine the best thrust profile,” Wang explains. “This can work well, but it has drawbacks. It assumes that there is no uncertainty in the system (for example, that the thrust of the engines is applied perfectly) and it simplifies the motion of the spacecraft by treating it as though it’s traveling through flat space instead of on a true curved geometry. Both shortcuts introduce errors  — our research aims to address these gaps.”

To improve landing precision, Wang will develop a curved-space geometric mathematical model, which takes into account the curved-space geometry of spacecraft motion rather than assuming flat space. To find a fuel-efficient landing trajectory, Wang will develop the model around optimal covariance steering, a stochastic control problem that both minimizes fuel costs while keeping the uncertainty of the spacecraft's exact landing spot within a safe amount.

It’s a problem that leverages his experience in theoretical math and his background in aerospace engineering. “I’m incredibly honored that NASA finds this research exciting and is supporting my pursuit of it,” he says. “There are so many fascinating engineering problems that could benefit from deeper theoretical scrutiny, especially using abstract machineries not typically covered in an engineering curriculum. I hope this inspires more theoretical researchers and graduate students to explore bridging these gaps.”

Astrobio in Focus

The Minor in Astrobiology will provide a broad, interdisciplinary introduction to the field of astrobiology while encouraging exploration beyond students’ primary fields of study. 

The program will foster the development of well-rounded scientists and engineers who will graduate with confidence in their knowledge and ability to engage in cutting-edge endeavors across the astrobiology discipline. 

"One of the most exciting aspects of the GT astrobiology minor is that it is truly interdisciplinary, enabling students to see how the arts and sciences operate synergistically," said Regents' Professor Lisa Yaszek, who teaches some of the classes. "This is particularly true of science fiction, which is often called 'the premier art form of modernity' because it emerged in tandem with the scientific and industrial revolutions and enables artists to communicate their experiences with science and technology and their hopes and fears about the future across centuries, continents, and cultures."

The Minor in Astrobiology is open to all undergraduates at Georgia Tech. Students who enroll now and meet program requirements may graduate with the minor designation as early as the end of Fall 2025 term.

Mariel Borowitz, who teaches space policy in the Sam Nunn School of International Affairs, said it's crucial for scientists and engineers to understand the implications of technology.

"Including space policy ensures that students understand how policy decisions and institutions affect the path and priorities for research. This gives them the tools to understand — and potentially engage in — policy development in this area, preparing them to be leaders in the field," said Borowitz.

Enrolled students will learn about the physical and chemical conditions for development of a habitable planet; deeply understand Earth, space, and planetary science as well as the origin and evolution of life on Earth; and critically evaluate scientific issues related to astrobiology in media and popular culture.

Habitable Planet

The foundation of the new minor is the popular School of Earth and Atmospheric Sciences (EAS) course EAS 1601: Habitable Planet. Led by EAS Assistant Professor Frances Rivera-Hernández, the course enrolls up to 300 students a semester and expands options for study and career horizons. 

"Students from a lot of different majors enjoy 1601 where they get a true sense for the broadness of astrobio — stars, galaxies, biology, life beyond Earth, and how we create technology and science to explore those places,” Rivera-Hernández explains.

Like the new minor, EAS 1601 is also open to all majors. The class is offered in person across fall and spring semesters, and also available online during the summer term.

“We’re purposely very flexible with that course and the overall minor,” adds EAS Jean “Chris” Purvis Professor Jennifer Glass. “Students use EAS 1601 as a launchpoint to pick their interests for their wider field of study and to hone career interests — whether that’s space, biology, and autonomous rovers; hunting for chemical signs of life beyond our planet; or becoming an entrepreneur.” 

Over the past five years, students in the class frequently asked for formal degree offerings in astrobiology. Glass and fellow faculty partnered with then-graduate fellow Tyler Roche to explore the idea of a minor, leveraging Sutherland Dean's Chair funding in 2021 to officially launch the Georgia Tech Astrobiology Program in tandem with the Astrobiology Graduate Certificate Program, Astrobiology Fellows, and ExplOrigins young researcher group. 

Astrobio and Beyond

The Astrobiology Program is now supported by the new Georgia Tech Space Research Initiative and co-directed by Rivera-Hernández and EAS Assistant Professor Christopher E. Carr, who holds a primary appointment in the Daniel Guggenheim School of Aerospace Engineering. 

Glass and Rivera-Hernández co-direct the Astrobiology Graduate Certificate Program, and co-direct the Astrobiology Minor with Nicholas Hud, Regents' Professor and Julius Brown Professor in the School of Chemistry and Biochemistry.

The team’s collaborative approach to interdisciplinary leadership mirrors unique opportunities ahead for students who are interested in exciting careers across the field of astrobiology and beyond. 

“The minor is designed across three broad divisions of study,” Glass adds. “Whether you’re curious about ‘Foundations of Life,’ want to dive deep into ‘Earth, Space, and Other Worlds,’ or are exploring career ideas for ‘Astrobiology in a Wider World,’ we’ve built a solid home for you in Astrobio at Tech.”

The Minor in Astrobiology will be listed in the 2025-26 Catalog beginning May 12.

According to The Planetary Society, more than 30 missions are slated to launch to the moon between 2024 and 2030, backed by the U.S., China, Japan, India, and various private corporations. That compares to over 40 missions to the moon between 1959 and 1979 and a scant three missions between 1980 and 2000.

A multidisciplinary team at Georgia Tech has found that while collision probabilities in orbits around the moon are very low compared to Earth orbit, spacecraft in lunar orbit will likely need to conduct multiple costly collision avoidance maneuvers each year. The Journal of Spacecraft and Rockets published the Georgia Tech collision-avoidance study in March.

“The number of close approaches in lunar orbit is higher than some might expect, given that there are only tens of satellites, rather than the thousands in low Earth orbit,” says paper co-author Mariel Borowitz, associate professor in the Sam Nunn School of International Affairs in the Ivan Allen College of Liberal Arts.

Borowitz and other researchers attribute these risky approaches in part to spacecraft often choosing a limited number of favorable orbits and the difficulty of monitoring the exact location of spacecraft that are more than 200,000 miles away.

“There is significant uncertainty about the exact location of objects around the moon. This, combined with the high cost associated with lunar missions, means that operators often undertake maneuvers even when the probability is very low — up to one in 10 million,” Borowitz explains. 

The Georgia Tech research is the first published study showing short- and long-term collision risks in cislunar orbits. Using a series of Monte Carlo simulations, the researchers modeled the probability of various outcomes in a process that cannot be easily predicted because of random variables. 

“Our analysis suggests that satellite operators must perform up to four maneuvers annually for each satellite for a fleet of 50 satellites in low lunar orbit (LLO),” said one of the study’s authors, Brian Gunter, associate professor in the Daniel Guggenheim School of Aerospace Engineering. 

He noted that with only 10 satellites in LLO, a satellite might still need a yearly maneuver. This is supported by what current cislunar operators have reported. 

Favored Orbits

Most close encounters are expected to occur near the moon’s equator, an intersection point between the orbit planes of commonly used “frozen” and low lunar orbits, which are preferred by many operators. Other possible regions of congestion can occur at the Lagrangian points, or regions where the gravitational forces of Earth and the moon balance out. Stable orbits in these regions have names such as Halo and Lyapunov orbits. 

“Lagrangian points are an interesting place to put a satellite because it can maintain its orbit for long periods with very little maneuvering and thrusting. Frozen orbits, too. Anywhere outside these special areas, you have to spend a lot of fuel to maintain an orbit,” he said.

Gunter and other researchers worry that if operators aren’t coordinated about how they plan lunar missions, opportunities for collision will increase in these popular orbits.

“The close approaches were much more common than I would have intuitively anticipated,” says lead study author Stef Crum.

The 2024 graduate of Georgia Tech’s aerospace engineering doctoral program notes that, considering the small number of satellites in lunar orbit, the need for multiple maneuvers was “really surprising.”

Crum, who is also co-founder of Reditus Space, a startup he founded in 2024 to provide reusable orbital re-entry services, adds that the cislunar environment is so challenging because “it’s incredibly vast.”

His research also examines ways to improve object monitoring in cislunar space. Maintaining continuous custody of these objects is difficult because a target’s position must be monitored over the entire duration of its trajectory. 

“That wasn’t feasible for translunar orbits, given the vast volume of cislunar orbit, which stretches multiple millions of kilometers in three dimensions,” he says.

By estimating a satellite’s orbit using observed data and constraining the presumed location and direction of the satellite, rather than continuous tracking (a process known as continuous custody), Crum greatly simplified the process. 

“You no longer need thousands of satellites or a set of enormous satellites to cover all potential trajectories,” he explains. “Instead, one or a few satellites are required, and operators can lose custody for a time as long as the connection is reacquired later.”

Since the team started their study, there has been a lot of interest in the moon and cislunar activity — both NASA and China’s National Space Administration are planning to send humans to the moon. In the last two years, India, Japan, the U.S., China, Russia, and four private companies have attempted missions to the moon. 

Why the Moon

Spacefaring nations’ intense interest in exploring the lunar surface comes as no surprise given that the moon offers a variety of resources, including solar power, water, oxygen, and metals like iron, titanium, and uranium. It also contains Helium-3, a potential fuel for nuclear fusion, and rare earth metals vital for modern technology. With the recent discovery of water ice, it could be a plentiful source for rocket fuel that can be created from liquifying oxygen and hydrogen needed to launch deep space missions to destinations like Mars. In February, Georgia Tech announced that researchers have developed new algorithms to help Intuitive Machines’ lunar lander find water ice on the moon.

Commercial space companies like Axiom Space and Redwire Space, as well as space agencies, are actively building lunar infrastructure, from satellite constellations to orbital platforms to support communication, navigation, scientific research, and eventually space tourism. 

A key project involves the Lunar Gateway, a joint venture of NASA and international space agencies like ESA, JAXA, and CSA, as well as commercial partners. Humanity’s first space station around the moon will serve as a central hub for human exploration of the moon and is considered a stepping stone for future deep space missions.

Getting Ahead of a Gold Rush to the Moon

All this activity underscores the urgency to get out in front of potential crowding issues — something that hasn’t occurred in LEO, where near-miss collisions, or conjunctions, are frequent. LEO, which is 100 to 1,200 miles above the Earth’s surface, is host to more than 14,000  satellites and 120 million pieces of debris from launches, collisions, and wear and tear, reports Reuters.

“Using the near-Earth environment as an example, the space object population has gone from approximately 6,000 active satellites in the early 2020s to an anticipated 60,000 satellites in the coming decade if the projected number of large satellite constellations currently in the works gets deployed. That poses many challenges in terms of how we can manage that sustainably,” observed Gunter. “If something similar happens in the lunar environment, say if Artemis (NASA’s program to establish the first long-term presence on the moon) is successful and a lunar base is established, and there is discovery of volatiles or water deposits, it could initiate a kind of gold rush effect that might accelerate the number of actors in cislunar space.”

For this reason, Borowitz argues for the need to begin working on coordination, either in the planning of the orbits for future missions or by sharing information about the location of objects operating in lunar orbit. She pointed out that spacecraft outfitted for moon missions are expensive, making a collision highly costly. Also, debris from such a scenario would spread in an unpredictable way, which could be problematic for other objects.

Gunter agreed, noting, “If we’re not careful, we could be putting a lot of things in this same path. We must ensure we build out the cislunar orbital environment in a smart way, where we’re not intentionally putting spacecraft in the same orbital spaces. If we do that, everyone should be able to get what they want and not be in each other’s way.”

Borowitz says some coordination efforts are underway with the UN Committee on the Peaceful Uses of Outer Space and the creation of an action team on lunar activities; however, international diplomacy is a time-consuming process, and it can be a challenge to keep pace with advancements in technology.

She contends that the Georgia Tech study could provide baseline data that “could be helpful for international coordination efforts, helping to ensure that countries better understand potential future risks.”

Gunter and Borowitz say that follow-on research for the team could involve looking into the Lunar Gateway orbit and other special orbits to see how crowded that space will likely get, and then do an end-to-end simulation of these orbits to determine the most effective way to build them out to avoid collision risks. Ultimately, they intend to develop guidelines to help ensure that future space actors headed to the moon can operate safely.

SRI will become the center of all things space-related at the Institute. It will work in partnership with academics, business partners, philanthropists, students, and governments.

Ready says the role of SRI is “to amplify the space-based research environment that we have had for decades at Georgia Tech by providing dedicated facility, communications, collaboration, and financial resources, as well as assistance on large-scale proposals.”

The existence of SRI is directly tied to one of Georgia Tech’s “Big Bets,” outlined in the Institute’s current Strategic Plan: “Double the Scale and Amplify the Impact of Our Research Enterprise.”

GTRI to Play a Prominent Role With SRI

“GTRI has an unfair advantage in so many areas: we've got great capabilities, great people, great equipment, great connections across the United States as well as the globe,” said Ready. “To be able to take curiosity-driven fundamental research and turn it into a widget, whether that widget is a radar or a spacecraft or whatever it may be, GTRI is good at that.”

“We're not a commercial entity, so we're not trying to make thousands, hundreds, or even dozens of a device or a system. We're very good at one-off prototypes, and that's what space research is. We're not trying to build a constellation of 1,000s of ‘Starlink’ satellites. We are trying to create sensors, systems, spacecraft, constellations -- whatever it takes – to solve problems, whether they're national security problems, scientific problems, economic problems, communication problems -- there are many uses for spacecraft.”

Ready’s vision for SRI emphasizes leveraging and enhancing the robust infrastructure already in place at GT and GTRI, including C-SHAFT (Center for Space Hardware Assembly, Fabrication and Testing). As he articulated during his vision presentation, before being named to the executive director role, he views GTRI facilities such as thermal vacuum chambers and ground station networks as strategic assets that provide Georgia Tech with a significant competitive edge in space research and exploration.

Ready’s leadership will emphasize bridging the robust academic and research elements within Georgia Tech to include all Colleges and GTRI. By strengthening the collaborative relationship among all arms of the Institute, Ready seeks to enhance Georgia Tech’s institutional capacity for securing competitive federal, industry and philanthropic funding. He plans to strategically use GTRI’s contract vehicles, such as its University Affiliated Research Center (UARC) agreements, to streamline funding processes, thereby advancing GTRI’s and Georgia Tech’s collective research enterprise.

Under Ready’s direction, educational and outreach initiatives will also expand significantly. Ready says he intends to draw on previous Georgia Tech successes, such as the Symposium on Space Innovations and championing “K through gray” educational programs. He intends to integrate educational activities that involve both academic and research personnel from across Georgia Tech and GTRI. These efforts aim to support the existing cadre of space engineering professionals, as well as cultivate a new generation of engineers and scientists equipped with the skills and experiences necessary for leadership in space technology.

Q&A with Jud Ready, SRI Executive Director

Q: What are your initial, big priorities for SRI?

Ready: We're looking for partnerships internally at Georgia Tech, within GTRI, in Georgia, and externally. Whether governmental, philanthropic, or industrial sponsorships, that's what we're seeking. We want SRI to help faculty, students, small businesses, major corporations, and the USA in general succeed in space.

Q: How soon and how aggressively will you pursue funding and sponsorships?

Ready: "Immediately. We've already got proposals pending. We'll continue pursuing federal funding, corporate funding, and philanthropic efforts. Space access has become much cheaper, opening new funding avenues."

Q: Will SRI take over existing projects such as Lunar Flashlight (a CubeSat integrated and tested by GTRI and operated by Georgia Tech) or MISSE (a NASA mission series in which GTRI is heavily involved)?

Ready: "No, SRI won’t take over someone's research projects. SRI will not be a principal investigator. It enables individual principal investigators, providing necessary resources, whether they're at GTRI, GT, or industry."

Q: Does SRI have a physical space, lab space, cleanrooms, etc.?

Ready: "The administrative offices are in the Coda building. But the resources we have at Georgia Tech and GTRI aren't moving. We have cleanrooms and testing facilities at Baker and Cobb County, antennas for communication, and eventually, we'll have a new building near Coca-Cola Tower.”

Q: Given the long-term nature of space research, do you have a short-term plan for SRI?

Ready: "I've certainly got a 90-day plan. We'll have something going on every month this fall. We’ll release an RFP for our CPI (centers, programs, initiatives) process around Labor Day. The LSIC fall meeting is at Georgia Tech on November 5-6. We're also organizing a networking event and a star-watching party for homecoming in October."

Q: Will you maintain your existing appointments at Georgia Tech and GTRI?

Ready: "Yes, I'm still 50/50. Technically, 49% SRI and 51% GTRI, so I didn't have to reorganize my reporting chain. I’ve dialed back my teaching a notch and only plan to teach my Material Science and Engineering of Sports class (MSE3300) next spring, but I will also be teaching my Vertically Integrated Project (VIP) class in the fall. And, of course, advising several graduate students along the way."

Q: Is there more to Jud Ready than just space research?

Ready: "I haven’t stopped thinking about space since Skylab. But yes, I like things more than space. I'm also a scout leader. I enjoy camping, fishing, sailing, and sports, especially, even though, historically, I’ve been exceptionally mediocre at them."

Georgia Tech’s 11 IRIs support collaboration between researchers and students across the Institute’s seven colleges, the Georgia Tech Research Institute (GTRI), national laboratories, and corporate entities to tackle critical topics of strategic significance for the Institute as well as for local, state, national, and international communities.

The structures they created greatly reduced the variability of mechanical properties typically found in recycled plastic. Their product also maintained the performance of the original plastic materials.

The researchers said their bio-inspired design could help cut manufacturing costs of virgin packaging materials by nearly 50% and offer potential savings of hundreds of millions of dollars. And, because less than 10% of the 350 million tons of plastics produced each year is effectively recycled, the Georgia Tech approach could keep more plastic out of landfills.

Aerospace engineering assistant professor Christos Athanasiou led the study, which was published in the journal Proceedings of the National Academy of Sciences (PNAS).

Before merging, both black holes were spinning exceptionally fast, and their masses fell into a range that should be very rare — or impossible. 

“Most models don't predict black holes this big can be made by supernovas, and our data indicates that they were spinning at a rate close to the limit of what’s theoretically possible,” says Margaret Millhouse, a research scientist in the School of Physics who played a key role in the research. “Where could they have come from? It raises interesting questions.”

A binary black hole merger absorbs characteristics from both of the contributors, she adds. “As a result, this is not only the most massive binary black hole ever seen but also the fastest-spinning binary black hole confidently detected with gravitational waves.”

“GW231123 is a record-breaking event,” says School of Physics Professor Laura Cadonati, who has been a member of the LIGO Scientific Collaboration since 2002. “LIGO has been observing the cosmos for 10 years now. This discovery underscores that there is still so much that this instrument can help us learn.”

A Cosmic View

The findings challenge current theories on how smaller black holes form, says School of Physics Assistant Professor and LIGO collaborator Surabhi Sachdev. Smaller black holes are the result of supernovae: dying and collapsing stars. During that collapse, explosions can tear apart or eject part of the star’s mass — limiting the size of the black hole that forms.

“Black holes from supernovae can weigh up to about 60 times the mass of our Sun,” she says. “The black holes in this merger were likely the mass of hundreds of suns.”

Because of its size, GW231123 also allowed the team to study the merger in unprecedented detail. “LIGO has observed scores of black hole mergers,” says Cadonati. “Of these, GW231123 has provided us with the clearest view of the ‘grand finale’ of a merger thus far. This adds a new clue to solve the puzzle that are black holes, including their origins and properties.”

“While we saw that our expectations matched the data, the extreme nature of this event pushed our models to their limits,” Millhouse adds. “A massive, highly spinning system like this will be of interest to researchers who study how binary black holes form.”

Decoding a Split-Second Signal

Millhouse and School of Physics Postdoctoral Fellow Prathamesh Joshi used Einstein’s equations for general relativity to confirm LIGO’s detections.

To find black holes, LIGO measures distortions in spacetime — ripples that are created when two black holes collide. These patterns in gravitational waves can be used to find the signature signal of black hole collisions. 

“In this case, the signal lasted for just one-tenth of a second, but it was very clear,” says Joshi. "Previously, we designed a special study to detect these interesting signals, which accounted for all the unusual properties of such massive systems — and it paid off!”

“To ensure it wasn’t noise, the Georgia Tech team first reconstructed the signal in a model-agnostic way,” Millhouse adds. “We then compared those reconstructions to a model that uses Einstein's equations of general relativity, and both reconstructions looked very similar, which helped confirm that this highly unusual phenomenon was a genuine detection.”

Sachdev says that seeing the signal at both LIGO Observatories — placed in Hanford, Washington and Livingston, Louisiana — was also critical. “These short signals are very hard to detect, and this signal is so unlike any of the other binary black holes that we've seen before,” she says. “Without both detectors, we would have missed it.”

A Decade of Discovery

While the team has yet to determine how the original black holes formed, one theory is that they may have resulted from mergers themselves. “This could have been a chain of mergers,” Sachdev explains. “This tells us that they could have existed in a very dense environment like a nuclear star cluster or an active galactic nucleus.” Their spins provide another clue as spinning is a characteristic usually seen in black holes resulting from a merge.

The team adds that GW231123 could provide clues on how larger black holes are formed — including the mysterious supermassive black holes at the center of galaxies.

“Gravitational wave science is almost a decade old, and we're still making fundamental discoveries,” says Millhouse. “It’s exciting that LIGO is continuing to detect new phenomena,  and this is at the edge of what we've seen thus far. There's still so much we can learn.”

The team expects to update their catalogue of black holes in August 2025, which will provide another window into how this exceptionally heavy black hole might fit into the universe, and what we can continue to learn from it.

In November 2024, JSC granted Assistant Professor Spencer Bryngelson exclusive access to the system through the JUPITER Research and Early Access Program (JUREAP).

By preparing Europe’s fastest supercomputer for launch, the joint project yielded valuable simulation data on the effects of shock waves in medicine and transportation.

“The shock-droplet problem has been a hallmark test problem in fluid dynamics for some decades now. It is sufficiently challenging to study that it keeps me scientifically interested, though the results are manifestly important,” Bryngelson said. 

“Understanding the droplet behavior in some extreme regimes remains an open scientific problem of high engineering value.”

Through JUREAP, JSC engineers tested Bryngelson’s Multi-Component Flow Code (MFC) on their computers. The project simulated how liquid droplets behave when struck by a large, high-velocity shock wave moving much faster than the speed of sound.

Tests produced visualizations of droplets deforming into pancake shapes before ejecting vortex rings as they broke apart from the shock wave. The experiments measured the swirls of air flow formed behind the droplets, known as vorticity.

Vorticity is one variable aerospace engineers consider when building aircraft designed to fly at supersonic and hypersonic speeds. Small droplets and vortices pose significant hazards for high-Mach vessels.

These computer models reduce the risk and cost associated with physical test runs. By simulating extreme scenarios, the JUREAP project demonstrated a safer and more efficient way to evaluate aerospace systems.

The human body is another fluid space where fast, high-energy flows can occur.

Simulations help medical researchers create less invasive shock wave treatments. This technology can be further applied for uses ranging from breaking up kidney stones to treating inflammation. 

MFC’s versatility for large- and small-scale applications made it suitable for testing JUPITER in its early stages. The project’s success even earned it a JUREAP certificate for scaling efficiency and node performance.

“The use of application codes to test supercomputers is common. We’ve participated in similar programs for OLCF Frontier and LLNL El Capitan,” said Bryngelson, a faculty member with Georgia Tech’s School of Computational Science and Engineering.

“Engineers at supercomputer sites usually find and sort most problems on their own. But deploying workloads characteristic of what the JUPITER will run in practice stresses it in new ways. In these instances, we usually end up identifying some failure modes.”

The JSC and Georgia Tech researchers named their joint project Exascale Multiphysics Flows (ExaMFlow).

ExaMFlow helps keep JUPITER on pace to become Europe’s first exascale supercomputer. This designation refers to any machine capable of computing one exaflop, or one quintillion (“1” followed by 18 zeros) calculations per second. 

All three systems that rank ahead of JUPITER are exascale supercomputers. They are El Capitan at Lawrence Livermore National Laboratory, Frontier at Oak Ridge National Laboratory, and Aurora at Argonne National Laboratory. 

JUPITER calculates more than 60 billion operations per watt. This makes the supercomputer the most energy-efficient system among the top five. 

ExaMFlow ran Bryngelson’s software on JSC’s JUWELS Booster and JUPITER Exascale Transition Instrument (JETI). The two modules form the backbone of JUPITER’s full design.

ExaMFlow’s report showed that MFC performed with near-ideal scaling behavior on JUWELS and JETI compared to similar systems based on NVIDIA A100 GPUs.

Access to NVIDIA hardware at Georgia Tech played a key role in ExaMFlow’s success.

The Institute hosts the Phoenix Research Computing Cluster, which includes A100 GPUs among its arsenal of components. Bryngelson’s lab owns NVIDIA A100 GPUs and four GH200 Grace Hopper Superchips. 

Since JUPITER is equipped with around 24,000 Grace Hopper Superchips, Bryngelson’s work with the hardware proved especially insightful for the ExaMFlow project.   

“The Grace Hopper chip is interesting. It’s not challenging to use like a regular GPU device when one is familiar with running NVIDIA hardware. The more fun part is using its tightly coupled CPU to GPU interconnect to make use of the CPU as well,” Bryngelson said. 

“It’s not immediately obvious how to best do this, though we used a few tricks to tune its use to our application. They appear to work nicely.”

JSC researchers Luis Cifuentes, Rakesh Sarma, Seong Koh, and Sohel Herff played important roles in running Bryngelson’s MFC software on early JUPITER modules. 

The ExaMFlow team included NVIDIA scientists Nikolaos Tselepidis and Benedikt Dorschner. 

The pair observed their company’s hardware used in the field. They return to NVIDIA with notes that help the corporation build the next devices tailored to the need of scientific computing researchers. 

“We try to be prepared for the latest, biggest computers. Being able to take immediate advantage of the largest systems is a valuable capability,” Bryngelson said. 

“When the early access systems arrive, it’s a great opportunity for the teams involved to test the machines, demonstrate and tune scientific software, and meet very capable new collaborators.”

More than half a century after the United States won the race to the moon, the White House is setting its sights on a new frontier: Mars. In a move reminiscent of the Apollo era, the administration has proposed landing Americans on the red planet by the end of 2026 — a bold initiative that has reignited national ambition and drawn comparisons to the space race of the 20th century. 

Karen Feigh and the 13-person committee found that the FAA hired only about two-thirds of the controllers it projected from 2013 to 2023. Due to attrition during that time — and because hiring didn’t accelerate until 2024 — 19 of the FAA’s largest facilities have 15% fewer people managing airspace than they need. 

For example, the report shows the tower at Hartsfield-Jackson Atlanta International Airport, the world’s busiest, is 17% below full staff. 

The National Academies of Sciences, Engineering, and Medicine report provides guidance to the FAA about establishing appropriate staffing levels. It also suggests specific improvements in hiring, training, scheduling, and fatigue management for the FAA’s 313 facilities.

"Our innovation for end-of-service wind turbine blades is both simple and elegant – at its core, our technology captures all the embodied energy in the composite materials in the blade," said Gentry, professor in the School of Architecture.

"The Re-Wind Network has pioneered structural recycling, the only of a number of competing technologies that upcycles the material of the blade and preserves the embodied energy from manufacturing," Gentry said.

"Little additional energy is used to remanufacture the blade and the life of the blade, typically 20 years, is extended at least 50 years. This is a win-win solution from an environmental and economic perspective."

Other methods for dealing with decommissioned wind blades involve mechanical grinding and landfilling of subsequent waste, an expensive and energy-intensive process, he said.

Team members include Gentry, Sakshi Kakkad, Cayleigh Nicholson, Mehmet Bermek, and Larry Bank, from the School of Architecture; Gabriel Ackall, Yulizza Henao, and Aeva Silverman, from the School of Civil and Environmental Engineering;  and Eric Johansen, a business consultant from Fiberglass Trusses Inc.

The team is part of the Re-Wind Network, a multinational research and development network which develops large-scale infrastructure projects from decommissioned wind turbine blades. 

Re-Wind's pedestrian bridges, known as BladeBridges, have already captured media attention. Two more BladeBridges are expected in Atlanta in 2024, Gentry said. Re-Wind has also developed, prototyped, and tested transmission poles made from blade segments. The team's other proposals include culverts, barriers, and floats.

The study, “Evidence for a composite volcano on the rim of Jezero crater on Mars,” was published this May in the Nature-family journal Communications Earth & Environment, and underscores how much we have left to learn about one of the most well-studied regions of Mars.

Lead author Sara C. Cuevas-Quiñones completed the research as an undergraduate during a summer program at Georgia Tech; she is now a graduate student at Brown University. The team also included corresponding author Professor James J. Wray (School of Earth and Atmospheric Sciences), Assistant Professor Frances Rivera-Hernández (School of Earth and Atmospheric Sciences), and Jacob Adler, then a postdoctoral fellow at Georgia Tech and now an assistant research professor at Arizona State University. 

“Volcanism on Mars is intriguing for a number of reasons — from the implications it has on habitability, to better constraining the geologic history,” Wray says. “Jezero Crater is one of the best studied sites on Mars. If we are just now identifying a volcano here, imagine how many more could be on Mars. Volcanoes may be even more widespread across Mars than we thought.”

A mountain in the margins

Wray first noticed the mountain in 2007, while considering Jezero Crater as a graduate student. 

“I was looking at low-resolution photos of the area and noticed a mountain on the crater’s rim,” he recalls. “To me, it looked like a volcano, but it was difficult to get additional images.” At the time, Jezero Crater was newly discovered, and imaging focused almost entirely on its intriguing water history, which is on the opposite side of the 28-mile-wide crater.

Then, Jezero Crater, due to these lake-like sedimentary deposits, was selected as the landing spot for the 2020 Perseverance Rover — an ongoing NASA mission seeking signs of ancient Martian life and collecting rock samples for possible return to Earth.

However, after landing, some of the first rocks Perseverance encountered were not the sedimentary deposits one might expect from a previously-flooded area — they were volcanic. Wray suspected he might know the origin of these rocks, but to make a case for it, he would need to show that the mountain on the edge of Jezero Crater could indeed be a volcano.

A new researcher — and old data

The opportunity presented itself several months after Perseverance landed when Cuevas-Quiñones applied to a Summer Research Experience for Undergraduates (REU) program hosted by the School of Earth and Atmospheric Sciences to work with Wray. 

“A previous study led by Briony Horgan (professor of planetary science at Purdue University) had also suggested that Jezero Mons could be volcanic,” Cuevas-Quiñones says. “I began wondering if there was a way to home in on these suspicions.”

The team partnered with study coauthor Rivera-Hernández, who specializes in characterizing the surface of planets and their habitability. They decided to use datasets gathered from spacecraft orbiting Mars to compare the properties of Jezero Mons to other, known, volcanoes. “We can’t visit Mars and definitively prove that Jezero Mons is a volcano, but we can show that it shares the same properties with existing volcanoes — both here on Earth and Mars,” Wray explains.

“We used data from the Mars Odyssey Orbiter, Mars Reconnaissance Orbiter, ExoMars Trace Gas Orbiter, and Perseverance Rover, all in combination to puzzle this out,” he adds. “I think this shows that these older spacecraft can be extremely valuable long after their initial missions end — these old spacecraft can still make important discoveries and help us answer tricky questions.”

For Cuevas-Quiñones, it also underscores the importance of REU programs and opportunities for undergraduates. “I was an undergraduate student at the time, and this was my first time conducting research,” she says. “It was fascinating to learn how different data sets could be used to decode the origin of a landscape. After Jezero Mons, it became clear to me that I would continue to study Mars and other planetary bodies.”

The search for life — and determining Mars’ age

The discovery makes the crater even more intriguing in the search for past life on Mars. A volcano so close to watery Jezero Crater could add a critical source of heat on an otherwise cold planet, including the potential for hydrothermal activity — energy that life could use to thrive. 

This type of system also holds interest for Mars as a whole. “The coalescence of these two types of systems makes Jezero more interesting than ever,” shares Wray. “We have samples of incredible sedimentary rocks that could be from a habitable region alongside igneous rocks with important scientific value.” If returned to Earth, igneous rocks can be radioisotope dated to know their age very precisely. Dating the Jezero Crater samples could be used to calibrate age estimates, providing an unprecedented window into the geologic history of the planet.

The take home message? “Mars is the best place we have to look in our solar system for signs of life, and thanks to the Perseverance Rover collecting samples in Jezero, the United States has samples from the best rocks in the best place on Mars,” Wray says. “If these samples are returned to Earth, we can do incredible, groundbreaking science with them.”

Wray was supported by NASA funding for Co-Investigators on HiRISE and CaSSIS. CaSSIS is a project of the University of Bern and funded through the Swiss Space Office via ESA’s PRODEX program. The instrument hardware development was also supported by the Italian Space Agency (ASI) (ASI-INAF agreement 2020-17-HH.0), INAF/Astronomical Observatory of Padova, and the Space Research Center (CBK) in Warsaw.

The instrument, the autofluorescence nephelometer (AFN) built by Droplet Measurement Technologies, will fire a laser beam out a window and use light scattering from individual particles to measure the size and composition of the planet’s aerosols, the tiny particles that make up the clouds. The AFN will only have about five minutes to collect data as the small probe falls through the clouds, and another 15 minutes to send data back to Earth before things get too extreme. The probe is not expected to reach the surface, where it is hot enough to melt lead, and the pressure is 90 times that of Earth’s surface.

Georgia Tech oversees all of the instrument’s field tests and modeling. The project, called VENUSIAN, is led by Christopher E. Carr, assistant professor in the Daniel Guggenheim School of Aerospace Engineering, with funding from NASA’s PSTAR program. Carr holds a joint appointment in the School of Earth and Atmospheric Sciences.

NASA also built a heat shield for Rocket Lab’s spacecraft and will provide navigation and communications support through the Deep Space Network.

“Is there life in the clouds of Venus? I don’t think so, but if it’s there, I want to find it,” says Carr, who admits that the more he studies Venus, the more interesting it becomes.

In March, his team tested the AFN in the field, flying it on a drone through Hawaii’s volcanic fog, a haze that forms because of volcanic emissions. The droplets are rich with sulfuric acid, similar to Venus’ atmosphere. 

“We got some valuable data,” says Carr. “This was the first time for our whole team from different institutions to be together in one place.” 

Collaborators from the Massachusetts Institute of Technology (MIT), the University of Colorado-Boulder, which managed and flew the drones, and Droplet Measurement Technologies joined the Georgia Tech contingent in Hawaii.

Sara Seager, professor of physics, professor of aeronautics and astronautics, and Class of 1941 Professor of Planetary Science at MIT, who serves as the science principal investigator for the Rocket Lab mission, emphasized the critical testing role Georgia Tech is playing ahead of the mission to Venus.

“Building the instrument is important, but what is also important is knowing how you’re going to interpret data when you get back. To understand that you need to use the instrument over and over again here on Earth. Professor Carr taking a lead on that from a science perspective is important,” says Seager, who will oversee two subsequent Morning Star Missions to Venus that the team envisions will culminate in an atmosphere sample return.

The Kilauea volcano, located in Hawaii Volcanoes National Park on the Big Island, began erupting as soon as the team started their first drone flight. The eruption grew more intense on the second day, giving the researchers a chance to run the AFN through its paces. While the flight test results are still preliminary, the team indicated that the instrument did detect volcanic ash and volcanic smog, which bodes well for the Venus mission. 

“It was cool to see our instrument in action,” says Snigdha Nellutla, a research engineer and data modeler, who recently finished her master’s in aerospace engineering. She simulates the AFN’s output in different environmental conditions, both during the Hawaii field tests and on the actual mission to Venus.

In Search of a Carbon Cycle

“We’re seeking evidence of a carbon cycle in the Venus atmosphere,” she said. “Life as we know it on Earth is carbon-based. Carbon compounds are delivered to Venus from meteorites. Are they rapidly degraded or do they persist in some form?”

Billions of years ago, Venus may have had as much water as Earth — but at some point in its evolution, carbon dioxide in the planet's atmosphere triggered an intense runaway greenhouse effect. This sent temperatures soaring, causing the planet's water to evaporate, and the hydrogen part of the water (H2O) was lost to space.

In 2020, astronomers detected phosphine in Venus’ atmosphere. This gas, often associated with biological activity on Earth, could signal signs of life. While the presence of phosphine is now debated, a rash of recent discoveries suggests that organic chemistry in the clouds could be much more complex than previously considered.

While Venus’ extreme surface temperatures are well documented, the one exception is found in the middle cloud layers, which have habitable temperatures. By looking at individual particles within the Venus atmosphere, researchers hope to learn about other compounds that could exist, including organic molecules that could influence a carbon cycle. The Hawaii measurements will serve as an important baseline to compare against what will be gathered on Venus. 

The Smoking Gun of Organics

The mission to Venus will also measure fluorescence, considered “a smoking gun” for possible organic materials, says Carr. 

On Venus’ super-rotating atmosphere, clouds take four Earth days to travel around the planet, while the planet spins in the same direction approximately 50 times slower.

“The differences with Venus’s atmosphere compared with Earth have forced our whole team to look at how we approach astrobiology completely differently,” he explains. “When we think of finding signs of life, we follow the water, but Venus has no water; it’s sulfuric acid.”

To Carr, the importance of the mission is to better understand Venus’ chemistry, given that sulfuric acid and water have different properties, which can contribute to or limit the kind of chemistry that can occur. 

“By understanding what might be possible, we can learn if different types of life might be possible. It also helps us know what to look for when we look for life,” he says. Even if there is no life in the clouds of Venus, there is likely to be interesting chemistry, based on extensive testing by members of the science team. This chemistry could be detected by the AFN as fluorescent aerosol particles.

VENUSIAN has enabled Georgia Tech aerospace engineering students to get a rare opportunity to test and model hardware that will fly in space. 

Students Celebrate Teamwork, Space Aspirations  

“As a first-year, I’ve had a variety of tasks, and that’s been fun for me as someone who is just starting to explore my career possibilities,” says Violet Oliver, who oversees the ground sampling tests. “This has been a really good introduction — getting my feet wet in what future space missions might look like and, more broadly, what the engineering test cycle looks like.”

“The biggest thing we learned was how to work together as a team,” adds Cassius Tunis, a senior in aerospace engineering. He managed the logistics, designed hardware to integrate the AFN and the drone, and served as the field study’s test engineer during the flights, where he communicated with the pilots and tracked their flight pattern.

“It’s been a goal of mine to work in the space industry since high school,” he said, crediting VENUSIAN with helping him pinpoint his career direction. “I see myself as the resident test engineer. Test engineering is a very operational, multidisciplinary field within aerospace. You get to wear a lot of different hats and interact with people of all different backgrounds.”

Carr indicated that the team will return to Hawaii later this year for final AFN field testing before the Venus mission. 

Looking to the 2026 launch, Seager says, “I’m looking forward to a safe launch and getting exciting data back. It’s Venus’ moment to shine,” she added, calling Venus the “quiet, overlooked gem” to Mars and Earth.

Carr expressed admiration for Rocket Lab’s founder and CEO, Peter Beck, whose passion for the Venus mission is well documented. 

“He exudes the true curiosity of a scientist and explorer. In Rocket Lab, we have a partner that is excited by discovery.”

1. What about space fascinates you? 
It all goes back to my dad being interested in space. In first grade, we went to a how-to-use-the-library class, and I came across a book about the Mercury and Apollo astronauts. I checked it out and renewed it over and over again. I eventually finished it in second grade. So, I’ve had a lifelong commitment since then to space.

2. What drew you to engineering? 
I grew up in Chapel Hill. In that same first grade class, we went to the University of North Carolina chemistry department. My mom is really into roses, and they froze a rose in liquid nitrogen then smashed it on the table. It broke into a million bits, and I was like, “What?!” The ability of science to solve the unknown grabbed me. And I had a series of very good science teachers — Mr. Parker in fifth grade, in particular. Then I took a soldering class in high school. We built a multimeter that I still have and still use, and various other things. And I suddenly discovered and started exploring engineering. Plus, I just like making things.

3. How did your career change from hoping to be an astronaut to being an accomplished materials engineer? 
When I started looking at colleges, that was my primary interest: What school would help me become an astronaut the quickest. I applied to Georgia Tech as an aerospace engineer, but was admitted as an undecided engineering candidate instead. It was the best thing that could have happened. Later, I got hired as an undergrad by a professor who was doing space-grown gallium arsenide on the Space Shuttle. Ultimately, they offered me a graduate position. I accepted, because I knew you needed an advanced degree to be an astronaut — and for a civilian, a Ph.D. in a relevant career such as materials science.

I applied so many times to be an astronaut — every time they opened a call from 1999 until just a few years ago. Never got in. But I was successful at writing proposals and teaching. So I started doing space vicariously through my students, writing research proposals on energy capture, such as solar cells; energy storage, such as super capacitors; and energy delivery like electron emission. They’re all enabled by engineered materials.

4. What makes Georgia Tech and GTRI a key contributor to the future of humans and science in space? 
Georgia Tech offers us so many unfair advantages over our competition. The equipment we’ve got. The students. You’ve got the curiosity-driven basic research coupled with the GTRI applied research model. We’ve had VentureLab and CREATE-X. Now we’ve got Quadrant-i to foster spinout companies from research.  

5. One of your solar cell technologies is headed to the Smithsonian National Air & Space Museum. What is it? 
Early in my career, we developed a way to texture thin film photovoltaics to allow for light trapping. Inverted pyramids are etched into silicon wafer-type solar cells so a photon of light has a chance to hit different surfaces and get absorbed. But thin film solar cells typically don’t etch well. I thought we could use carbon nanotubes to form a scaffolding, a structure like rebar. It’s mechanically reinforcing, but also electrically conductive. We coat the thin film solar cell material over the carbon nanotube arrays. You’ve got these towers, and you get this photon pinballing effect. Most solar cells perform best when perpendicular to the sun, but with mine, off angles are preferred. That’s great for orbital uses, because the faces and solar panels of spacecraft are frequently off-angle to the sun. And then you don’t have the complexity of mechanical systems adjusting the solar arrays. So, we got funding to demonstrate these solar cells on the International Space Station three times, and those are some of the cells we provided to the Smithsonian.

“When I was 14, I dreamed about being in space one day,” recalls Chen, 22, a native of Hong Kong and a Ph.D. student in aerospace engineering. “I think the industry has been making space more accessible to everyone. Commercialization is a big part of enabling this.”

Gantt, an engineer and former U.S. Army veteran graduating with an MBA from the Scheller College of Business this spring, remembered seeing the space shuttle retire and companies begin privatizing space as he entered young adulthood. 

“I’ve always been interested in space, and a lot of it comes from the challenge of going to space,” he observes. “Seeing how hard it is to get to space and seeing it become achievable — that to me was the most attractive thing about it.”

For Gantt, the feeling always brings to mind John F. Kennedy’s famous line that spelled out America’s space ambitions: “We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard.”

Recognizing Georgia Tech’s aerospace strengths, Gantt didn’t waste time building bridges within Scheller and in other parts of Georgia Tech. He founded the Scheller MBA Space Club, a first at the College, to track the industry as it grows and develops. 

“I came from a military background, so I had my eye on the defense industry going into the MBA program. Georgia Tech, being the No. 2 aerospace engineering undergraduate school in the nation, I knew they already had strong industry connections. Making connections was a big goal coming into this program.”

Assessing Early-Stage Space Tech 

He took part in the Entrepreneurship Assistants Program (EAP), which pairs a Scheller MBA student with a faculty or student inventor to evaluate early-stage technology for potential commercialization. He evaluated two space-related technologies, one with Chen’s support. 

“The EAs conduct technology commercialization assessments and develop a business model canvas. By applying an entrepreneurial strategy compass, they predict potential go-to-market strategies for new technology,” says Paul Joseph, principal in the Office of Commercialization’s Quadrant-i unit, who created the EAP.

 (See sidebar to read more about the EAP and the specific technologies assessed.)

Tapping Into a Nearly $2T Industry

According to McKinsey & Co., the space technology market, fueled by advancements in satellite technology, commercial space travel, and 5G networks, is projected to reach $1.8 trillion by 2035.

“We're seeing an industry shifting from a multibillion-dollar market cap to a multitrillion-dollar market cap in less than a decade. If you look at this from a business perspective, this is a massive addressable market for entrepreneurs," says Gantt.

From its Center for Space Technology and Research to the new Center for Space Policy and International Relations and labs like the Space Systems Design Lab, which focuses on areas such as CubeSat propulsion, lunar research, and hypersonic flight, Georgia Tech excels in space research across disciplines. In July, Georgia Tech will launch the Space Research Institute (SRI), one of its newest Interdisciplinary Research Institutes (IRI), to foster additional collaboration in this growing field.

“At Georgia Tech, there are competencies across every single College that will help to augment our understanding of space,” says Alex Oettl, professor of strategy and innovation in Scheller College, whose interest in the new space economy spans the last 20 years. “When you look at the technologies coming from Georgia Tech, they can impact this future trillion-dollar industry.”

 An economist by training, Oettl led Georgia Tech’s involvement in the Creative Destruction Lab-Atlanta, a multi-university program that helped commercialize early-stage scientific technologies.

Leveraging Affordable Launch

The emergence of affordable launch, spurred by SpaceX’s introduction of the Falcon 9 rocket using reusable rocket technology, has made space much more accessible, from biomedical companies to academic institutions.

“Because there has been a drop in the cost of accessing space, it allows experimentation to flourish,” says Oettl. 

He recalls Mark Costello, former chair of the Daniel Guggenheim School of Aerospace Engineering, explaining how he could launch a CubeSat into Low Earth Orbit out of his research budget, whereas before it would have been cost-prohibitive.

Today, Georgia Tech students and researchers are poised to capitalize on the new space economy stack — from new launch capabilities to new development in propellants and in-space operations and maintenance to more powerful sensors on Earth-observation satellites.

“I’ve seen firsthand the traction occurring on the commercial side. There are a lot of social scientists waking up to the opportunity that exists and thinking about business dynamics that will emerge as a result of this great opportunity,” he says.

Georgia Tech, an interdisciplinary, tech-focused university, brings significant capabilities across its Colleges to drive new and emerging technologies that have implications for space. 

“Space hits on all the strengths that exist at the various Colleges,” Oettl explains. “Faculty at Georgia Tech are pushing the boundary and showing our students innovations that will emerge in the space economy that are not immediately obvious — such as in adjacent industries.”

Oettl calls these first-order and spillover impacts of new technology. By first-order impacts, he means businesses can take advantage of these opportunities and create new products on top of the original innovation. By spillovers, he cites as an example an Earth-observation satellite enabling other industries to take advantage of data from the ground. For instance, insurance companies are one of the largest users of space technology by way of satellite imagery.

Bringing Capabilities Together Through New Space IRI

The SRI will bring together the best in engineering, computer science, policy, and business research across Georgia Tech. Along the way, it could help engineers and computer scientists think with a more business-minded approach to pitch their innovations to the commercial space sector. 

“You don’t see a lot of engineers having that inherent ability,” notes Gantt. “The Space IRI can shine by fostering collaboration between business students and engineers, enabling them to develop innovative go-to-market strategies and clearly define the unique value propositions these technologies offer to end users. You can bring these people together and create some forward momentum in the space industry.”

The day began with opening remarks from Georgia Tech’s Executive Vice President of Research Tim Lieuwen, Vice President of Interdisciplinary Research Julia Kubanek, and the SRI executive committee, comprised of Professor Glenn Lightsey and Associate Professors Mariel Borowitz and Jennifer Glass. They provided an update on the SRI's latest achievements and its elevation to the Space Research Institute, one of Georgia Tech’s Interdisciplinary Research Institutes, on July 1.

“Space research is much broader than building spacecraft…it includes science, policy, business, and culture. We are here to celebrate all aspects of space research at Georgia Tech,” said Lightsey.

Borowitz lead a panel discussion on the implications of current space policies and the role of academic institutions in shaping the future of space exploration. It highlighted the importance of policy decisions in advancing space research and ensuring sustainable development. Jonathan Goldman, director of Quadrant-i at Georgia Tech, and his panel of entrepreneurs then discussed the commercialization of space technologies and the opportunities arising. They shared how collaboration between academia and industry can drive innovation and bring these new technologies to market.

The Georgia Tech Research Institute (GTRI) organized a space poster session during the lunch break to provide insight into the various space research projects happening there. This networking opportunity highlighted the breadth of work at GTRI and enabled researchers and students to present their projects to attendees. 

The Keynote speaker, Georgia Tech Alumnus Griff Russell, M.S. ME 1999, president of Gryphon Effect, LLC, and former SpaceX F9 vehicle manager, shared his personal journey to inspire future researchers. His talk, “From a letter to an astronaut to the trenches of Falcon 9 and beyond: Setting the foundation for accelerated Moon to Mars exploration” followed Russell’s path to the space industry, chronicling a letter he wrote to an astronaut early in his career to his current role as an entrepreneur. Russell shared his thoughts on the future of space exploration and encouraged students in the room to move fast and develop innovative new space technologies. “The time is now for you to make a difference,” he said. 

Professor Thom Orlando then led a panel of experts from other Georgia universities on the Human Space Initiative in the State of Georgia. Orlando and the panelists discussed the state's contributions to human spaceflight and the potential for future missions. This was followed by a panel on Earth analog field studies led by Assistant Professor Frances Rivera-Hernandez. Panelists including students explained how studying Earth analogs, like lava tubes and deserts, can help researchers better understand other planetary environments. Georgia Tech graduate students gave brief presentations chronicling recent fieldtrips and the data they gather in the field. The final session of the day led by Professor Lightsey showcased Georgia Tech’s space-related student organizations and the importance of engaging the next generation of scientists and engineers in space exploration.

As the Space Research Initiative transitions into the Space Research Institute, Georgia Tech is prepared to lead groundbreaking research, and Yuri’s Day gave attendees a preview of things to come. For more information about the SRI and the research at Georgia Tech, visit our website.

Coleman, a recognized augmented reality expert at Georgia Tech, has been working with the PartWorks’ engineering team to solve aircraft maintenance challenges, leading to measurable improvements in labor costs, training, repair quality, turnaround time, and maintenance process validation. This research partnership has led to the development of several patented and patent-pending solutions related to aircraft maintenance.

“I could not have hired anybody with the diverse skill sets that both Maribeth and the Georgia Tech team brought to bear,” said Scott Geller, CEO of PartWorks. “We’ve utilized different and complicated skill sets, sometimes in small quantities, that have made our project work very cost-effective. We’ve used an iterative research and development process that hasn’t had a shocking cost or huge surprises. And the Georgia Tech team has been both easy and fun to work with, too.”

This collaboration has led to PartWorks launching a new aircraft maintenance, repair, and overhaul (MRO) augmented reality solution called RepĀR™. Designed for both military and commercial aviation, RepĀR’s augmented reality overlay transforms structural repairs by ensuring accuracy, reducing labor costs, minimizing human error, and accelerating return-to-service timelines. 

RepĀR rapidly captures structural repair data, embedding spatial awareness and real-time validation into maintenance workflows. Novice technicians can achieve results beyond their operational experience, while seasoned technicians experience measurable productivity gains.

“RepĀR exemplifies how targeted computer vision applications can deliver immediate value in aerospace manufacturing and maintenance,” said Shelley Peterson, CEO of Wizard Wells. “By precisely identifying fastener locations and validating tool placement, it reduces rework, minimizes human error, and ensures tasks are performed right the first time.”

PartWorks demonstrated RepĀR at the Aviation Week Network’s MRO Americas, which took place April 8 – 10 at the Georgia World Congress Center in Atlanta.

“This collaborative research with industry demonstrates why Georgia Tech has interdisciplinary research institutes such as IPaT, and why you have research faculty,” said Coleman. “You’re probably not going to be able to get some Ph.D. students to do this work. The focus here with PartWorks is on translation. It’s cross-disciplinary collaboration and translation built on augmented reality work we’ve been doing for 25 years and implementing cutting-edge technology crafted to the right context to support aircraft maintenance.”

“This Georgia Tech collaboration and augmented reality MRO research and development are in conjunction with a multiyear contract we’re working on with the Air Force Research Lab (AFRL) in Dayton, Ohio,” said Geller. “We’re appreciative of their partnership and excited to be getting commercial interest in RepĀR from both military and commercial aviation OEMs and MROs as well as space industry companies.”

The four-year $6.7 million Safety Aware Learning Assured Autonomy for Aviation project will be headed up by Hever Moncayo from Embry-Riddle Aeronautical University, and include collaborations with Georgia Tech, the University of Texas, Arlington, the University of Southern California, and Collins Aerospace. 

“I’m thrilled to join forces and combine our multifaceted expertise to enhance the safety of Advanced Air Mobility vehicles. Our research is paving the way to make them a reality,” Vamvoudakis stated. “This ULI will bring together experts from academia and industry to speed up progress in aviation safety, improve the reliability and autonomy of future air mobility, and facilitate the integration of autonomous safety systems into commercial and regulatory standards.”

The project will investigate the significant knowledge gaps that have slowed down the national airspace’s use of AAM vehicles such as drones and air taxis. Vamvoudakis and his team will create smart safety system software that can learn independently. This system will help monitor, manage, and control these vehicles safely and reliably. It will also produce national safety guidelines to ensure the vehicles follow safe flight paths and make harmless decisions based on their own learning. Additionally, they will allow vehicles to autonomously adjust their own actions to ensure safety within specific operational limits. The idea is that future AAM vehicles will use smart, non-traditional components to stay safe and perform well, even in unexpected situations and emergencies. Establishing an intelligent system that can diagnose and predict issues independently will be crucial. This system will help ensure these vehicles meet their mission goals safely, despite challenges like unpredictable environments.

This ULI research effort will support the Aeronautics Research Mission Directorate’s (ARMD) outcome for 2020-2035: Initial safe and efficient integration of highly automated vehicles into the National Airspace System (NAS) by introducing aviation systems with bounded autonomy, capable of carrying out function-level goals.

This is Vamvoudakis’ second ULI. He is a part of the Safe and Secure Autonomy Project that is still active.

Co-Pis: K. Merve Dogan, Maj Mirmirani, and Victor Fraticelli (Embry Riddle Aeronautical University), Kyriakos G. Vamvoudakis (Georgia Institute of Technology), Nicholas Gans and Yijing Xie (University of Texas, Arlington), Petros Ioannou (University of Southern California), and Kevin Kronfeld (Collins Aerospace) will play a crucial role in this collaborative effort.
 

New NASA-funded research by Georgia Tech offers fresh insights into the phenomenon of space weathering. Examining Apollo lunar samples at the nanoscale, Tech researchers have revealed risks to human space missions and the possible role of space weathering in forming some of the water on the moon. 

Most previous studies of the moon involved instruments mapping it from orbit. In contrast, this study allowed researchers to spatially map a nanoscale sample while simultaneously analyzing optical signatures of Apollo lunar samples from different regions of the lunar surface — and to extract information about the chemical composition of the lunar surface and radiation history. 

The researchers recently published their findings in Scientific Reports. 

“The presence of water on the moon is critical for the Artemis program. It’s necessary for sustaining any human presence and it’s a particularly important source for oxygen and hydrogen, the molecules derived from splitting water,” said Thomas Orlando, Regents’ Professor in the School of Chemistry and Biochemistry, co-founder and former director of the Georgia Tech Center for Space Technology and Research, and principal investigator of Georgia Tech’s Center for Lunar Environment and Volatile Exploration Research (CLEVER).

Building on a Decade of Lunar Science Research 

As a NASA SSERVI (Solar System Exploration Research Virtual Institute), CLEVER is an approved NASA laboratory for analysis of lunar samples and includes investigators from multiple institutes and universities across the U.S. and Europe. Research areas include how solar wind and micrometeorites produce volatiles, such as water, molecular oxygen, methane, and hydrogen, which are all crucial to supporting human activity on the moon. 

Georgia Tech has built a large portfolio in human exploration and lunar science over the last decade with two NASA Solar System Exploration Research Virtual Institutes: CLEVER and its predecessor, REVEALS (Radiation Effects on Volatiles and Exploration of Asteroids and Lunar Surfaces). 

Studying Moon Samples at the Nanoscale Level 

Georgia Tech’s labs are world-renowned, particularly for analyzing surfaces and semiconductor materials. For this work, the Georgia Tech team also tapped the University of Georgia (UGA) Nano-Optics Laboratory run by Professor Yohannes Abate in the Department of Physics and Astronomy. While UGA is a member of CLEVER, its nano-FTIR spectroscopy and nanoscale imaging equipment was historically used for semiconductor physics, not space science. 

“This is the first time these tools have been applied to space-weathered lunar samples, and it’s the first we’ve been able to see good signatures of space weathering at the nanoscale,” says Orlando. 

Normal spectrometers are at a much larger scale, with the ability to see more bulk properties of the soil, explains Phillip Stancil, professor and head of the UGA physics department. 

The UGA equipment enabled the study of samples “in tens of nanometers.” To illustrate how small nanoscale is, Stancil says a hydrogen atom is .05 nanometers, so 1 nm is the size of 20 atoms if placed side by side. The spectrometers provide high-resolution details of the lunar grains down to hundreds of atoms. 

“We can look at an almost atomistic level to understand how this rock was formed, its history, and how it was processed in space,” Stancil says. 

“You can learn a lot about how the atom positions change and how they are disrupted due to radiation by looking at the tiny sample at an atomistic level,” says Orlando, noting that a lot of damage is done at the nanoscale level. They can determine if the culprit is space weathering or from a process left over during the rock’s formation and crystallization. 

Finding Radioactive Damage, Evidence of Water 

The researchers found damage on the rock samples, including changes in the optical signatures. That insight helped them understand how the lunar surface formed and evolved but also provided “a really good idea of the rocks’ chemical composition and how they changed when irradiated,” says Orlando. 

Some of the optical signatures also showed trapped electron states, which are typically missing atoms and vacancies in the atomic lattice. When the grains are irradiated, some atoms are removed, and the electrons get trapped. The types of traps and how deep they are, in terms of energy, can help determine the radiation history of the moon. The trapped electrons can also lead to charging, which can generate an electrostatic spark. On the moon, this could be a problem for astronauts, exploration vehicles, and equipment. 

“There is also a difference in the chemical signatures. Certain areas had more neodymium (a chemical element also found in the Earth’s crust) or chromium (an essential trace mineral), which are made by radioactive decay,” Orlando says. The relative amounts and locations of these atoms imply an external source like micrometeorites. 

Translating Research to Human Risks on the Moon 

Radiation and its effects on the dust and lunar surface pose dangers to people, and the main protection is the spacesuit. 

Orlando sees three key risks. First, the dust could interfere with spacesuits’ seals. Second, micrometeorites could puncture a spacesuit. These high-velocity particles form after breaking off from larger chunks of debris. Like solar storms, they are hard to predict, and they’re dangerous because they come in at high-impact velocities of 5 kilometers per second or higher. “Those are bullets, so they will penetrate the spacesuits,” Orlando says. Third, astronauts could breathe in dust left on the suits, causing respiratory issues. NASA is studying many approaches for dust removal and mitigation. 

Mapping the Moon: Going from Nanoscale to Macroscale 

The next research phase will involve combining the UGA analysis tools with a new tool from Georgia Tech that will be used to analyze Apollo lunar samples that have been in storage for over 50 years. 

“We will combine two very sophisticated analysis tools to look at these samples in a level of detail that I don’t think has been done before,” Orlando says. 

The goal is to build models that can feed into orbital maps of the moon. To get there, the Georgia Tech and UGA team will need to go from nanoscale to the full macro scale to show what’s happening on the lunar surface and the location of water and other key resources, including methane, needed to support humanity’s moon and deep-space exploration goals.

Georgia Tech’s Space Exploration and Analysis Laboratory (SEAL) has developed new algorithms that are headed to the Moon, as part of the Intuitive Machine’s IM-2 mission. The mission is sending a Nova-C class lunar lander named Athena to the Moon’s south pole region to test technologies and collect data that aim to enable future exploration. The mission is part of NASA’s Commercial Lunar Payload Services (CLPS) initiative.

NASA’s Double Asteroid Redirection Test (DART), led by Johns Hopkins University’s Applied Physics Laboratory, was the first full-scale kinetic deflection mission to test how kinetic deflection could effectively push an asteroid measuring 150 meters in diameter. The 580-kg spacecraft (impactor) collided with the target asteroid, Dimorphos, at a speed of 6.1 km/second on September 26, 2022, making the target’s speed 2.7 mm/s. This speed change could gradually make the course deviate from the original one. The more time that elapses after impact, the further it moves away from the Earth. Even though Dimorphos was not a threat before the impact, it was chosen as a test target for DART’s kinetic deflection test.

Georgia Tech Professor Masatoshi Hirabayashi’s critical contribution to DART was recently published in Nature Communications. The study, “Elliptical ejecta of asteroid Dimorphos is due to its surface curvature” analyzed the behavior of fragments coming out by the high-speed DART impact and their push of the asteroid. This work was in collaboration with Professor Fabio Ferrari from Politecnico di Milano, who jointly published the study, “Morphology of ejecta features from the impact on asteroid Dimorphos.”  

Imagine a cannonball flying through the air and hitting a concrete wall. The wall shutters and fragmented pieces disperse at high speeds. Those smaller fragments, called ejecta, are known to be a key factor in controlling the asteroid push.

The study found that the ejecta from the impact site on Dimorphos highly depends on the asteroid’s shape. As a rule of thumb, a cannonball hitting a flat concrete wall creates ejecta departing from the wall at an angle of about 45 degrees from the wall’s surface. The cloud of ejecta thus looks like a waffle cone. However, if the concrete wall’s surface is tilted against the impact direction, the fragment ejection changes, making the ejecta structure differ even if the impactor has the same mass and speed. 

“This changes the asteroid push dramatically. Dimorphos has a squashed round shape, like an M&M,” Hirabayashi explained, “If the impact is large, more ejecta fly out of the surface but are more affected by surface tilts. This process makes the ejecta deviate from the ideal direction, reducing the asteroid push.” 

For the DART impact on Dimorphos, the study identified the impact scale and the asteroid’s rounded surface lowered the asteroid push by 56% compared to when Dimorphos was tested as an entirely flat wall. Thus, sending a large impactor does not mean a big push, and considering how to send impactors strategically is necessary. One way to keep the asteroid push effective is to send multiple small impactors rather than a single large impactor. This way, each small impactor may avoid the target’s rounded shape, and the net asteroid push by multiple impacts can be more efficient than the single impactor.

Ferrari’s study offered crucial information for Hirabayashi’s conclusions. “We used Hubble Space Telescope’s images and numerical simulations to quantify a viable mechanism of the ejecta evolution and successfully estimated ejected particles’ mass, velocity, and size. We also found complex interactions of such particles with the asteroid system and solar radiation pressure, i.e., sunlight pushing ejecta particles,” Ferrari said. “Documenting how ejecta looks over time offers crucial insights into how the DART impact acted on ejecta, giving tight constraints on the target asteroid’s properties.”

NASA’s DART mission was a success, and Hirabayashi’s study discovered an innovative approach to kinetic deflection, offering new potential for its future demonstration in space. He is building a new capability of characterizing a target’s properties beneficial for planetary defense, such as mass, size, composition, etc., at limited observational conditions. This is aligned with the fast reconnaissance concept, a new community effort that develops planetary defense strategies to identify these properties within a limited time and resources. This work continues to evolve Georgia Tech into a key player in planetary defense, connecting international communities. 
 

It's a $10 million joint mission led by the University of Michigan called STARI — STarlight Acquisition and Reflection toward Interferometry. Georgia Tech’s engineers will build the propulsion systems for a pair of briefcase-sized CubeSats that will fly in orbit a few hundred yards away from one another, bouncing starlight back and forth. 

The technology could be used someday to better understand if any known exoplanets are capable of supporting life as we know it.

Interferometry is already used to study stars, gas clouds, and galaxies. Instead of using one large telescope, several smaller telescopes work as a team. The machines swap starlight to create higher resolution images than are possible from a single telescope. 

Scientists and engineers have recently proposed using interferometry to locate exoplanets. 

STARI will determine if the same type of coordination and light transmission can be done using less expensive CubeSats.

According to David Ballantyne, associate chair for Academic Programs and professor in the School of Physics, the new major is unique because it focuses on the future of astronomy and astrophysics, especially in the era of discoveries made by the James Webb Space Telescope and the Laser Interferometer Gravitational-Wave Observatory (LIGO).

“We made a concerted effort when crafting this degree to make it modern and forward-facing,” says Ballantyne. “It is very much focused on the next decade of astronomy and astrophysics, providing a strong emphasis on computational skills, data analysis, and big data.”

The new degree includes coursework on the fundamental physical processes and laws that govern planetary systems, stars, galaxies, and the Universe as a whole. These core topics are complemented by training in computational and data analysis techniques that can be applied to a variety of disciplines. 

For Ballantyne, the degree program should appeal to students who are interested in pursuing careers in space science research as well as those interested in non-research career paths. 

“This program prepares students to solve complex problems in a very quantitative, rigorous way. Such problem solving and computational skills are highly marketable for a range of career paths,” he adds.

The evolution of astrophysics at Tech 

While astronomy coursework and outreach have long existed at the Institute, astrophysics officially began in 2008, when the School of Physics launched the Center for Relativistic Astrophysics (CRA). Today, the Center boasts more than a dozen faculty and research scientists, with expertise spanning high-energy astrophysics, extrasolar planets, gravitational-wave astronomy, and astroparticle physics.

As the CRA’s faculty roster grew, the School expanded its offering of astrophysics courses. A concentration in astrophysics for physics majors was launched during the 2013-14 academic year. A short time later, the School introduced an astrophysics certificate for non-majors. The new astrophysics major and minor — which will replace the concentration and certificate, respectively — reflects a new chapter in the history of astrophysics education and research at Georgia Tech.  

“Most of our peer institutions have an astronomy or astrophysics degree so the creation of this program at Georgia Tech was a natural fit,” says Ballantyne. “Our program fills a critical need considering that there are few options in the U.S. Southeast for students to obtain this type of training at an institution of Georgia Tech’s caliber.”

Declaring the astrophysics major and minor

Current students

Current students can declare the astrophysics major starting next semester, following the standard major change process for undergraduates. The astrophysics minor will be available to all Georgia Tech undergraduates starting summer 2025.  

Incoming students

Astrophysics will be added to the list of majors beginning with the admissions application for Summer 2025 (transfer students) and the 2026-27 academic year (first-year students). 

In the interim, transfer students enrolling for the Spring 2025 semester should follow the standard major change process for undergraduates. Students applying to Georgia Tech for the 2025-26 academic year should select “physics” as their major during the application process and choose “astrophysics” once admitted, during the major confirmation process. 

A recent study by Daniel Guggenheim School of Aerospace Engineering Associate Professor Kai James, Lee Alacoque, and Richard Bulliet analyzes the wheels’ invention and its evolution. Their analysis supports a new theory that copper miners from the Carpathian Mountains in southeastern Europe may have invented the wheel. However, the study also recognizes that the wheel’s evolution occurred incrementally over time — and likely through considerable trial and error. The findings suggest that the original developers of the wheel benefited from uniquely favorable environmental conditions that augmented their human ingenuity. The study, published in the journal Royal Society Open Science, has gained the worldwide attention of experts and more than 58 media outlets, including  Popular Mechanics, Interesting Engineering, and National Geographic en Español. 

“The way technology evolves is very complex. It's never as simple as somebody having an epiphany, going to their lab, drawing up a perfect prototype, and manufacturing it — and then end of story,” said James. “The evidence, even before our theory, suggests that the wheel evolved over centuries, across a very broad geographical range, with contributions from many different people, and that's true of all engineering systems. Understanding this complexity and seeing the process as a journey, rather than a moment in time, is one of the main outcomes of our study.” 

Necessity Is the Mother of Invention

In 3900 B.C., the Neolithic copper miners from the Carpathian Mountains lacked written language, and they were not advanced mathematically or scientifically. However, they discovered the wheel as a means to an end.

Recently, archeologists uncovered a series of small drinking mugs that rolled on wheels. There were features on the mugs, like wickerwork patterns, indicative of woven basketry used by miners around 3900 B.C. These replicas represent the earliest known depictions of wheeled transport.

Tools of Engagement

James and his team use computational analysis and design as a forensic tool to learn about the past, studying engineered systems designed by prehistoric people. Computational analysis offers a deeper understanding of how these systems were created. 

“We have to interpret clues from ancient societies without a writing system — artifacts like bows and arrows, flutes, or boats — but we need to use additional tools to do this,” James explained. “Carbon dating tells us when, but it doesn't tell us how or why. Using solid mechanics and computational modeling to recreate these environments and scenarios that gave rise to these technologies is a potential game-changer.”

Their theory suggests that the wheel evolved from simple rollers, which took the form of a series of untethered cylinders, poles, or tree trunks. These rollers were arranged side-by-side in a row on the ground, and the workers would transport their cargo on top of the rollers to avoid the friction caused by dragging. 
“Over time, the shape of these rollers evolved such that the central portion of the cylinder grew progressively narrower, eventually leaving only a slender axle capped on either end by round discs, which we now refer to as wheels,” James explained.

The researchers derived a series of mathematical equations that describe the physics of the rollers. They then created a computer algorithm that simulates the progression from roller to wheel-and-axle by repeatedly solving these equations.  

“Our investigation also indicates that environmental conditions played a key role in this evolutionary process,” he said. “Previous studies have shown that rollers are only effective under very specific circumstances.  They require flat, firm, and level terrain, as well as a straight path.  Neolithic mines, with their human-made tunnels and covered terrain would have offered an environment highly conducive to roller-based transport.”

The research was funded by National Science Foundation grant # 2311078.

Other Research on the Horizon

James’ research group is currently working to create algorithms to design aircraft structures for crashworthiness, focusing on helicopters. He uses these algorithms to design vehicles that can withstand impact with minimal structural damage and minimal passenger injury.

He is also designing 3D-printed morphing mechanisms.  These mechanisms contain active materials that change shape in response to heating.  By systematically combining active and passive materials in a precise spatial arrangement, James’ group is able to encode specific motions into the material layout. In this way, they create specialized mechanisms that transform into pre-programmed shapes upon being submerged in a heated water bath.

Compartmentalization is how all living systems are organized today — from proteins and small molecules sharing space in separate phases to dividing labor and specialized functions within and among cells.

Now, with $6 million in support from NASA, a team of researchers led by Georgia Tech’s Frank Rosenzweig will study the organizing principles of compartmentalization in a five-year project called Engine of Innovation: How Compartmentalization Drives Evolution of Novelty and Efficiency Across Scales.

It's one of seven new projects selected recently by NASA as part of its Interdisciplinary Consortia for Astrobiology Research (ICAR) program. ICAR is embedded among NASA’s five Astrobiology Research Coordination Networks (RCNs). Rosenzweig is co-lead for the RCN launched in 2022, LIFE: Early Cells to Multicellularity.

“We’re excited by the prospect of exploring this fundamental question through the interplay of theory and experiment,” said Rosenzweig, professor in the School of Biological Sciences, whose team of co-Investigators includes biochemists, geologists, cell biologists, and theoreticians from leading NASA research centers: Jeff Cameron, Shelley Copley, Alexis Templeton, and Boswell Wing from the University of Colorado Boulder; Josh Goldford and Victoria Orphan from California Institute of Technology; and John McCutcheon from Arizona State University. Collaborating with them is Chris Kempes, professor at the Santa Fe Institute.

Rosenzweig is also eager to eventually collaborate with existing ICAR teams, such as MUSE, led by the University of Wisconsin’s Betül Kaçar, a former Georgia Tech postdoctoral researcher, and newly selected teams, such as Retention of Habitable Atmospheres in Planetary Systems, led by Dave Brain at University of Colorado Boulder.

Meanwhile, he plans to build upon Georgia Tech’s outstanding reputation in astrobiology, where a cluster of researchers, such as Jen Glass, Nick Hud, Thom Orlando, Amanda Stockton, and Loren Williams, among others, is engaged in a diverse range of work supported by NASA.

“This is just the latest chapter in a long history of excellence in NASA research at Georgia Tech, one written by my colleagues across the Institute,” Rosenzweig said.

Vamvoudakis received $400,000 from the National Science Foundation for his proposal, “Improving Safety by Synthesizing Interacting Model-based and Model-free Learning Approaches.” This is the first grant on Safe Learning-enabled Systems (SLES) awarded to Georgia Tech from NSF. He and his team will establish a framework that leads to the design and implementation of SLES in which safety is ensured with high confidence levels. The framework will leverage tools from control theory, multi-agent autonomy, and formal methods for rigorously probabilistic reasoning to create safe learning-enabled systems. Before anyone releases an autonomous machine, the public expects it to be safe for those around it. For example, sensors in drones and other machines are sensitive to infiltration, malfunction, and the environment. If the wind is strong, the drone would need to be able to adjust to the environment, stay on course, and perhaps change altitude. If the drone encounters a telephone pole or even a person in its path, it would be able to adjust accordingly without waiting for human control. 

His research approach will take elements from various theories and combine them to improve the safety of these LES within the machine.

“Our approach algorithmically combines model-based and model-free reinforcement learning for enhancing safety by using the learned model to predict how well a safe policy will behave and then update the resulting actions,” Vamvoudakis explained. “As a result, our approach does not rely on improving the model and does not require an infinite amount of time for convergence. Instead, our plan optimally enhances safety and combines the predefined time-convergent actions generated to achieve high performance in the specified task.”

The fundamental knowledge created in his research could inform how future-assured autonomous systems with embodied intelligence can be built. Their results could inform the design of key enablers of the global economy, including smart and connected cities, networked actions of smart and autonomous systems by enabling system flexibility, efficiency, and capacity, and automated financial trading, such as creating automated news digests around finance.

Gaming Strategies Inform Military LES Frameworks

Autonomous machines are changing the way that the military operates. Uncrewed battles between autonomous systems require the systems to learn and adapt to unknown environments and to distinguish allies from enemies. Learning-enabled systems are trained to take the circumstances at hand and give recommendations for the desired response.

When humans have control over these machines, this is considered humans in the loop. When humans move further into the background and give the machines decision-making autonomy, it is called humans on the loop. Humans would still have oversight, but the machine could ultimately decide without human approval.

Through his newly awarded $480,000 project “Embodied and Secure Physical Intelligence with Possible Humans-on-the Loop in Complex Adaptive Systems” with the Army Research Office (ARO), Vamvoudakis and his team are developing decision-making algorithms to assist during conflict in adversarial environments. This is needed because military maneuvers can be unpredictable, and autonomous machines need to be able to adapt accordingly. He will use game-theoretic strategies to inform his work.

Vamvoudakis’ team has created algorithms in the context of games, where a “defender” wants to regulate a cyber-physical system around a trimming point, but an “attacker” intends to disrupt this regulation as much as possible.

They also employed level-k thinking to capture the behavior of the attacker. Particularly, instead of assuming that the attacker can reason perfectly about the behavior of the defender, the employed level-k thinking model imposed that the attacker can only make finitely-many (though arbitrarily many) steps of reasoning about what the defender might do, how the attacker can best respond to that, how the defender can then best respond. 

The project is a continuation of his ARO YIP award that developed a way to understand different types of attackers in a unified framework. Attackers who think a little ahead are called low-level, while those who think more strategically, like those near a Nash equilibrium, are called high-level. This understanding helps create better defense strategies without assuming that attackers always act perfectly. 

To demonstrate how this model works in real military situations, he and his students looked at it through the lens of a pursuit-evasion game. They found that using level-k thinking to understand and respond to attackers is more effective than assuming attackers always optimize their strategies perfectly.

MathWorks Gift to Enhance Learning for Artificial Intelligence

Current methods for protecting closed-loop reinforcement learning systems (artificial intelligence where the system continuously learns and adapts based on feedback from the environment) don't work well against potential threats. These existing methods often rely on guesswork, need a deep understanding of the system, and require a lot of training time. They also fail to guarantee safety when facing adversaries. 

Vamvoudakis’ MathWorks gift, “Adversarial Reinforcement Learning” aims to create a new generation of smart, flexible, autonomous systems that can learn and adapt. This is the first-ever gift from MathWorks made to Georgia Tech. 

“We will develop the next generation of agile, highly adaptive autonomous systems that use mechanisms from cognition and learning to process information from distributed sensors. In particular, looking to autonomous systems appearing in nature for inspiration,” he said. Specifically, behavioral scientists have validated the need for intermittent data sharing in learning tasks. They have shown that the central nervous system in human beings minimizes effort and sorts through impulses and stimuli by maintaining intermittent signaling. Specifically, the spinal cord transmits a channel of information and effectively exploits its neural resources via intermittent strategies to produce a sequence of muscle-bone interactions that induce movement.”

By looking to such ideas, they will develop safe and strong reinforcement learning methods to handle teamwork, assign tasks, and manage resources effectively. They will also collaborate with MathWorks to create useful toolboxes and provide internship opportunities.

Georgia Tech Ph.D. student Austin P. Wright is first author of a paper that introduces Nested Fusion. The new algorithm improves scientists’ ability to search for past signs of life on the Martian surface. 

In addition to supporting NASA’s Mars 2020 mission, scientists from other fields working with large, overlapping datasets can use Nested Fusion’s methods toward their studies.

Wright presented Nested Fusion at the 2024 International Conference on Knowledge Discovery and Data Mining (KDD 2024) where it was a runner-up for the best paper award. KDD is widely considered the world's most prestigious conference for knowledge discovery and data mining research.

“Nested Fusion is really useful for researchers in many different domains, not just NASA scientists,” said Wright. “The method visualizes complex datasets that can be difficult to get an overall view of during the initial exploratory stages of analysis.”

Nested Fusion combines datasets with different resolutions to produce a single, high-resolution visual distribution. Using this method, NASA scientists can more easily analyze multiple datasets from various sources at the same time. This can lead to faster studies of Mars’ surface composition to find clues of previous life.

The algorithm demonstrates how data science impacts traditional scientific fields like chemistry, biology, and geology.

Even further, Wright is developing Nested Fusion applications to model shifting climate patterns, plant and animal life, and other concepts in the earth sciences. The same method can combine overlapping datasets from satellite imagery, biomarkers, and climate data.

“Users have extended Nested Fusion and similar algorithms toward earth science contexts, which we have received very positive feedback,” said Wright, who studies machine learning (ML) at Georgia Tech.

“Cross-correlational analysis takes a long time to do and is not done in the initial stages of research when patterns appear and form new hypotheses. Nested Fusion enables people to discover these patterns much earlier.”

Wright is the data science and ML lead for PIXLISE, the software that NASA JPL scientists use to study data from the Mars Perseverance Rover.

Perseverance uses its Planetary Instrument for X-ray Lithochemistry (PIXL) to collect data on mineral composition of Mars’ surface. PIXL’s two main tools that accomplish this are its X-ray Fluorescence (XRF) Spectrometer and Multi-Context Camera (MCC).

When PIXL scans a target area, it creates two co-aligned datasets from the components. XRF collects a sample's fine-scale elemental composition. MCC produces images of a sample to gather visual and physical details like size and shape. 

A single XRF spectrum corresponds to approximately 100 MCC imaging pixels for every scan point. Each tool’s unique resolution makes mapping between overlapping data layers challenging. However, Wright and his collaborators designed Nested Fusion to overcome this hurdle.

In addition to progressing data science, Nested Fusion improves NASA scientists' workflow. Using the method, a single scientist can form an initial estimate of a sample’s mineral composition in a matter of hours. Before Nested Fusion, the same task required days of collaboration between teams of experts on each different instrument.

“I think one of the biggest lessons I have taken from this work is that it is valuable to always ground my ML and data science problems in actual, concrete use cases of our collaborators,” Wright said. 

“I learn from collaborators what parts of data analysis are important to them and the challenges they face. By understanding these issues, we can discover new ways of formalizing and framing problems in data science.”

Wright presented Nested Fusion at KDD 2024, held Aug. 25-29 in Barcelona, Spain. KDD is an official special interest group of the Association for Computing Machinery. The conference is one of the world’s leading forums for knowledge discovery and data mining research.

Nested Fusion won runner-up for the best paper in the applied data science track, which comprised of over 150 papers. Hundreds of other papers were presented at the conference’s research track, workshops, and tutorials. 

Wright’s mentors, Scott Davidoff and Polo Chau, co-authored the Nested Fusion paper. Davidoff is a principal research scientist at the NASA Jet Propulsion Laboratory. Chau is a professor at the Georgia Tech School of Computational Science and Engineering (CSE).

“I was extremely happy that this work was recognized with the best paper runner-up award,” Wright said. “This kind of applied work can sometimes be hard to find the right academic home, so finding communities that appreciate this work is very encouraging.”

At its most basic, turbulence comprises disorderly fluctuations over a wide range of scales in both time and three-dimensional space. These complexities mean that many fundamental aspects are still not understood. Computers can help unravel the mystery, but direct numerical simulations based on exact physical laws have always been very resource-intensive. Their challenges are greatest when investigating rare, very large fluctuations.

Now, Frontier, the world's first — and still fastest — Exascale computer, capable of a quintillion operations per second, is helping researchers to better understand turbulence.

“Turbulence is very complex, theories are incomplete, and laboratory measurements are arduous,” said P.K. Yeung, a professor in the Daniel Guggenheim School of Aerospace Engineering with a courtesy joint appointment in the George W. Woodruff School of Mechanical Engineering. “A world-leading resolution of over 35 trillion grid points on Frontier is expected to lead to new discoveries, which in turn can facilitate advances in modeling where both assumptions and predictions can be tested numerically."

Yeung and his team accessed Frontier, located at the Oak Ridge National Laboratory, when it first went online and also received large allocations of time on the machine from the prestigious INCITE program, which is run by the U.S. Department of Energy's Office of Science. The power of Frontier resides primarily in powerful graphical processing units (GPUs), which compute rapidly. Yeung's group published a journal article that describes a highly successful algorithm specifically designed to take maximum advantage of Frontier's features to make simulations at extremely high resolution feasible and efficient.

“In many scientific fields, people thought calculations of this magnitude were not possible, but now we are there, perhaps earlier than anticipated,” Yeung said. “Our work on turbulence simulations also demonstrates several principles of advanced GPU programming of interest in other fields, especially those where so-called pseudo-spectral methods are important. The science impacts of our extreme scale simulations are expected to be further enhanced by public data-sharing in partnership with the National Science Foundation-supported Johns Hopkins Turbulence Database project."

Meet 2024 IRIM Initiative Leads

Stephen Balakirsky; Regents' Researcher, Georgia Tech Research Institute & Panagiotis Tsiotras; David & Andrew Lewis Endowed Chair, Daniel Guggenheim School of Aerospace Engineering | Proximity Operations for Autonomous Servicing

Why It Matters: Proximity operations in space refer to the intricate and precise maneuvers and activities that spacecraft or satellites perform when they are in close proximity to each other, such as docking, rendezvous, or station-keeping. These operations are essential for a variety of space missions, including crewed spaceflights, satellite servicing, space exploration, and maintaining satellite constellations. While this is a very broad field, this initiative will concentrate on robotic servicing and associated challenges. In this context, robotic servicing is composed of proximity operations that are used for servicing and repairing satellites in space. In robotic servicing, robotic arms and tools perform maintenance tasks such as refueling, replacing components, or providing operation enhancements to extend a satellite's operational life or increase a satellite’s capabilities.

Our Approach: By forming an initiative in this important area, IRIM will open opportunities within the rapidly evolving space community. This will allow us to create proposals for organizations ranging from NASA and the Defense Advanced Research Projects Agency to the U.S. Air Force and U.S. Space Force. This will also position us to become national leaders in this area. While several universities have a robust robotics program and quite a few have a strong space engineering program, there are only a handful of academic units with the breadth of expertise to tackle this problem. Also, even fewer universities have the benefit of an experienced applied research partner, such as the Georgia Tech Research Institute (GTRI), to undertake large-scale demonstrations. Georgia Tech, having world-renowned programs in aerospace engineering and robotics, is uniquely positioned to be a leader in this field. In addition, creating a workshop in proximity operations for autonomous servicing will allow the GTRI and Georgia Tech space robotics communities to come together and better understand strengths and opportunities for improvement in our abilities.

Matthew Gombolay; Assistant Professor, Interactive Computing | Human-Robot Society in 2125: IRIM Leading the Way

Why It Matters: The coming robot “apocalypse” and foundation models captured the zeitgeist in 2023 with “ChatGPT” becoming a topic at the dinner table and the probability occurrence of various scenarios of AI driven technological doom being a hotly debated topic on social media. Futuristic visions of ubiquitous embodied Artificial Intelligence (AI) and robotics have become tangible. The proliferation and effectiveness of first-person view drones in the Russo-Ukrainian War, autonomous taxi services along with their failures, and inexpensive robots (e.g., Tesla’s Optimus and Unitree’s G1) have made it seem like children alive today may have robots embedded in their everyday lives. Yet, there is a lack of trust in the public leadership bringing us into this future to ensure that robots are developed and deployed with beneficence.

Our Approach: This proposal seeks to assemble a team of bright, savvy operators across academia, government, media, nonprofits, industry, and community stakeholders to develop a roadmap for how we can be the most trusted voice to guide the public in the next 100 years of innovation in robotics here at the IRIM. We propose to carry out specific activities that include conducting the activities necessary to develop a roadmap about Robots in 2125: Altruistic and Integrated Human-Robot Society. We also aim to build partnerships to promulgate these outcomes across Georgia Tech’s campus and internationally.

Gregory Sawicki; Joseph Anderer Faculty Fellow, School of Mechanical Engineering & Aaron Young; Associate Professor, Mechanical Engineering | Wearable Robotic Augmentation for Human Resilience 

Why It Matters: The field of robotics continues to evolve beyond rigid, precision-controlled machines for amplifying production on manufacturing assembly lines toward soft, wearable systems that can mediate the interface between human users and their natural and built environments. Recent advances in materials science have made it possible to construct flexible garments with embedded sensors and actuators (e.g., exosuits). In parallel, computers continue to get smaller and more powerful, and state-of-the art machine learning algorithms can extract useful information from more extensive volumes of input data in real time. Now is the time to embed lean, powerful, sensorimotor elements alongside high-speed and efficient data processing systems in a continuous wearable device.

Our Approach: The mission of the Wearable Robotic Augmentation for Human Resilience (WeRoAHR) initiative is to merge modern advances in sensing, actuation, and computing technology to imagine and create adaptive, wearable augmentation technology that can improve human resilience and longevity across the physiological spectrum — from behavioral to cellular scales. The near-term effort (~2-3 years) will draw on Georgia Tech’s existing ecosystem of basic scientists and engineers to develop WeRoAHR systems that will focus on key targets of opportunity to increase human resilience (e.g., improved balance, dexterity, and stamina). These initial efforts will establish seeds for growth intended to help launch larger-scale, center-level efforts (>5 years).

Panagiotis Tsiotras; David & Andrew Lewis Endowed Chair, Daniel Guggenheim School of Aerospace Engineering & Sam Coogan; Demetrius T. Paris Junior Professor, School of Electrical and Computer Engineering | Initiative on Reliable, Safe, and Secure Autonomous Robotics 

Why It Matters: The design and operation of reliable systems is primarily an integration issue that involves not only each component (software, hardware) being safe and reliable but also the whole system being reliable (including the human operator). The necessity for reliable autonomous systems (including AI agents) is more pronounced for “safety-critical” applications, where the result of a wrong decision can be catastrophic. This is quite a different landscape from many other autonomous decision systems (e.g., recommender systems) where a wrong or imprecise decision is inconsequential.

Our Approach: This new initiative will investigate the development of protocols, techniques, methodologies, theories, and practices for designing, building, and operating safe and reliable AI and autonomous engineering systems and contribute toward promoting a culture of safety and accountability grounded in rigorous objective metrics and methodologies for AI/autonomous and intelligent machines designers and operators, to allow the widespread adoption of such systems in safety-critical areas with confidence. The proposed new initiative aims to establish Tech as the leader in the design of autonomous, reliable engineering robotic systems and investigate the opportunity for a federally funded or industry-funded research center (National Science Foundation (NSF) Science and Technology Centers/Engineering Research Centers) in this area.

Colin Usher; Robotics Systems and Technology Branch Head, GTRI | Opportunities for Agricultural Robotics and New Collaborations

Why It Matters: The concepts for how robotics might be incorporated more broadly in agriculture vary widely, ranging from large-scale systems to teams of small systems operating in farms, enabling new possibilities. In addition, there are several application areas in agriculture, ranging from planting, weeding, crop scouting, and general growing through harvesting. Georgia Tech is not a land-grant university, making our ability to capture some of the opportunities in agricultural research more challenging. By partnering with a land-grant university such as the University of Georgia (UGA), we can leverage this relationship to go after these opportunities that, historically, were not available.

Our Approach: We plan to build collaborations first by leveraging relationships we have already formed within GTRI, Georgia Tech, and UGA. We will achieve this through a significant level of networking, supported by workshops and/or seminars with which to recruit faculty and form a roadmap for research within the respective universities. Our goal is to identify and pursue multiple opportunities for robotics-related research in both row-crop and animal-based agriculture. We believe that we have a strong opportunity, starting with formalizing a program with the partners we have worked with before, with the potential to improve and grow the research area by incorporating new faculty and staff with a unified vision of ubiquitous robotics systems in agriculture. We plan to achieve this through scheduled visits with interested faculty, attendance at relevant conferences, and ultimately hosting a workshop to formalize and define a research roadmap.

Ye Zhao; Assistant Professor, School of Mechanical Engineering | Safe, Social, & Scalable Human-Robot Teaming: Interaction, Synergy, & Augmentation

Why It Matters: Collaborative robots in unstructured environments such as construction and warehouse sites show great promise in working with humans on repetitive and dangerous tasks to improve efficiency and productivity. However, pre-programmed and nonflexible interaction behaviors of existing robots lower the naturalness and flexibility of the collaboration process. Therefore, it is crucial to improve physical interaction behaviors of the collaborative human-robot teaming.

Our Approach: This proposal will advance the understanding of the bi-directional influence and interaction of human-robot teaming for complex physical activities in dynamic environments by developing new methods to predict worker intention via multi-modal wearable sensing, reasoning about complex human-robot-workspace interaction, and adaptively planning the robot’s motion considering both human teaming dynamics and physiological and cognitive states. More importantly, our team plans to prioritize efforts to (i) broaden the scope of IRIM’s autonomy research by incorporating psychology, cognitive, and manufacturing research not typically considered as technical robotics research areas; (ii) initiate new IRIM education, training, and outreach programs through collaboration with team members from various Georgia Tech educational and outreach programs (including Project ENGAGES, VIP, and CEISMC) as well as the AUCC (World’s largest consortia of African American private institutions of higher education) which comprises Clark Atlanta University, Morehouse College, & Spelman College; and (iii) aim for large governmental grants such as DOD MURI, NSF NRT, and NSF Future of Work programs.

The SRI is the hub of all things space-related at Georgia Tech. It connects research institutes, labs, facilities, Schools, and Colleges to foster the conversation about space across Georgia and beyond. As a budding Interdisciplinary Research Institute (IRI), the SRI currently encompasses three core centers that contribute distinct interdisciplinary perspectives to space exploration.

Center for Space Technology and Research

The Center for Space Technology and Research (CSTAR) is a hub dedicated to furthering the expansion of Georgia’s aerospace industry, which is already the state’s No. 1 economic driver. The center's team at Georgia Tech conducts cutting-edge research in fields such as astrophysics, Earth science, planetary science, robotics, space policy, space technology, materials science, and space systems engineering.

CSTAR boasts a collaborative network of more than 100 Georgia Tech faculty members and research staff, supported by annual funding exceeding $20 million. Its contribution to space research is highlighted by its active multiyear research grants totaling over $100 million. Each year, CSTAR also contributes to the academic community with around 100 peer-reviewed journal articles and provides mentorship to dozens of graduate and undergraduate students, shaping the next generation of space research.

Members of CSTAR have contributed to a variety of spaceflight projects, from observing the atmosphere of Jupiter, to creating carbon nanotube-based technology on CubeSats, to building an innovative, dual-use antenna that is simultaneously a critical life-saving handrail and a radio emitter inside an airlock on the International Space Station. Several examples of this research will soon be part of a new permanent display in the National Air and Space Museum in Washington, D.C. 

“The work done by the Georgia Tech research community in space is phenomenal,” said CSTAR Director Jud Ready. “We have worked on the International Space Station, launched numerous free-flying CubeSats in low Earth orbit, as well as our current crowning achievement, the Lunar Flashlight CubeSat, which is the world’s only heliocentric spacecraft currently owned and operated by an academic institution that recently demonstrated planetary optical navigation techniques for the first time, by any organization — including NASA.” Future missions include materials demonstrations on a lunar lander, as well as additional orbital activities of both the Earth and moon.

“The SRI will increase our reach and impact over and above these prior activities by at least an order of magnitude,” he said. “I am excited for what the future holds for Georgia Tech students, faculty, and research partners as a result of this new organization.”

Center for Relativistic Astrophysics

The Center for Relativistic Astrophysics (CRA) is housed within the College of Sciences’ School of Physics. The center’s mission is to provide students with education and training in the key research areas of astroparticle physics, theoretical astrophysics, and gravitational wave astrophysics. 

CRA researchers study the breadth of space, ranging from the early universe’s large-scale structure to particle interactions. They also study black holes and the merger of compact objects, the potential outcome of the evolution of stellar binary systems, and — closer to home — exoplanets and stars found in the Milky Way. Of particular strength are computational astrophysics and multi-messenger astrophysical studies with neutrinos, photons, and gravitational waves. 

In addition, CRA researchers actively participate in major international collaborations, such as the operations and development of existing and future detectors, including the IceCube Neutrino Observatory, the LIGO and LISA gravitational wave observatories, X-ray observatories NuSTAR and Athena, and gamma-ray detectors VERITAS and CTA.

“Bringing together all space research under a single umbrella will be a huge boon to the CRA’s research efforts and visibility,” said John Wise, CRA director. “I am excited about the opportunities the SRI will bring forth within such a collaborative environment, especially the prospect of Georgia Tech leading a space mission that can test the theoretical work performed within the CRA.”

Georgia Tech Astrobiology

Astrobiology research at Georgia Tech, which includes experts in biochemistry, physics, aerospace engineering, planetary science, and astronomy, as well as others, seeks to answer these age-old questions: What is the origin of life? Does life exist on other worlds?

Georgia Tech’s astrobiology community includes students, staff, and faculty across campus, the educational curriculum, the Exploring Origins student-run group, an astrobiology fellows program, and keystone events. 

Many globally recognized researchers in this field are at Georgia Tech, and their recent discoveries hint at the potential for life on Mars and ocean worlds like Europa. Astrobiology at Tech brings together these faculty with scholars in the humanities and social sciences to share their research with the public and give it a broader cultural context. 

The Georgia Tech Astrobiology Graduate Certificate Program, an interdisciplinary initiative across several Schools and Colleges, is designed to broaden student participation in astrobiology. An undergraduate minor is in development. The purpose of these programs is to expand opportunities for both undergraduate and graduate students in the interdisciplinary field of astrobiology.

“One of the main reasons I came to Georgia Tech in 2020 is its vibrant astrobiology program,” said Christopher E. Carr, co-director of Georgia Tech Astrobiology. “It’s a true pleasure to have such amazing colleagues.”

Each instrument can measure elemental variability in both dissolved aqueous samples as well as solids/minerals via laser ablation microsampling from a Teledyne Iridia laser ablation system. Together the system can measure isotopes at precision in elemental systems from Li and U.

Planned applications include: (1) high-resolution measurements of Ca, Sr, Ba, Mg, and B elemental and isotopic variability in seawater and marine and terrestrial carbonates for paleoclimate reconstructions, (2) (U-Th)/Pb dating and Hf isotope measurements to study the origin of critical mineral deposits, with a potential engineering application and the development of novel methods for increasing precision/accuracy and minimizing sample consumption during routine analyses of water quality and environmental contamination.

The MCF welcomes users interested in these and other potential applications of this new facility to their scientific and engineering research to contact David Tavakoli (atavakoli6@gatech.edu).

For the next 378 days, Brockwell, a 1999 civil engineering graduate, and three other crew members participated in the study designed to gain insights into the challenges of deep space exploration and its effects on human health and performance. The crew performed robotic operations, habitat maintenance, agricultural activities, and simulated surface walks in the "sandbox" with the assistance of virtual reality while enduring intentional resource limitations, isolation, and confinement. 

A structural engineer by day, he has always dreamed of space travel, and when a fellow Yellow Jacket alerted Brockwell to the application for the CHAPEA mission, he seized the opportunity.  

"Sometimes, you get chances in your lifetime, and if I don't get a chance to actually go to Mars, if I can take this chance to help us get there as a planet, I'm honored," he said. 

Once inside the 1,700-square-foot habitat, Brockwell's role as the CHAPEA mission's flight engineer focused on infrastructure, building design, and organizational leadership. As much as he learned from his tasks throughout the mission, like anticipating possible failure points and contingency planning, NASA learned even more through physical and cognitive monitoring.  

"There was a lot of science, but some of the science was focused on us as the participants — our physiology and our performance — to make the mission as realistic as possible," he said.  

Communication is a key element in space travel. Getting a message from Mars back to family and friends or mission control on Earth took 20 minutes on average for the crew inside the habitat, testing their ability to isolate. Without constant communication with the outside world, the crew fostered camaraderie through team activities and celebrated birthdays and holidays together. Brockwell's ingenuity wasn't limited to official tasks; he used a 3D printer to create a bracket for mounting a mini-basketball hoop.  

Meals inside the habitat mirrored the shelf-stable food system of the International Space Station. While cultivated crops like tomatoes supplemented their main supply, Brockwell says there is a common misconception about astronaut food.  

"I say with all sincerity, it was delicious." His favorite dish was a peanut chicken and wild rice mix, but the crew often got creative by mixing soups and proteins to create new dishes. 

Other than the food, the biggest surprise to Brockwell was how quickly the mission was completed.    

"I hoped and thought it would be that way, but we proved that a well-comprised crew can have a good time while doing this. There were a lot of clichéd expectations that there would be issues that we just didn't have. I think we demonstrated that a mission like this can be a huge success and an enjoyable, positive experience, not just something to be endured," he said.  

Brockwell says that his time at Georgia Tech allowed him to learn the fundamentals of engineering principles and taught him to keep an open mind when exploring how things work. After receiving a master's degree in aeronautics from the California Institute of Technology and completing the CHAPEA mission, he believes systems engineering can aid deep space exploration efforts for the next generation.  

"Thinking about the effect of every component on every other component and the emergent properties from complex systems is crucial. I think that systems thinking is going to become increasingly important. Ecology and ecological thinking need to be part of it, especially for aerospace. If you're thinking about deep space exploration, an understanding of ecological principles and closed-loop systems will be key," he said.  

At the end of the mission, Brockwell savored the sights and smells of Earth for the first time in over a year, saying that's what he missed the most. But if the opportunity arose to take the 152-million-mile flight to Mars, he'd be on the first ship out.   

Lieuwen is a Regents’ Professor, the David S. Lewis, Jr. Chair in the Daniel Guggenheim School of Aerospace Engineering, and executive director of the Strategic Energy Institute. His research interests range from clean energy and propulsion systems to energy policy, national security, and regional economic development. He works closely with industry and government to address fundamental problems and identify solutions in the development of clean energy systems and alternative fuels. 

A proud Georgia Tech alumnus, Lieuwen (M.S. ME 1997, Ph.D. ME 1999) has had a remarkable academic career. He is a member of the National Academy of Engineering and is a fellow of the American Society of Mechanical Engineers, the American Institute of Aeronautics and Astronautics, the American Physical Society, the Combustion Institute, and the Indian National Academy of Engineering (foreign fellow). He has received numerous awards, including the ASME George Westinghouse Gold Medal and the AIAA Pendray Award. He serves on governing or advisory boards of three Department of Energy national labs: Oak Ridge National Laboratory, Pacific Northwest National Laboratory, and the National Renewable Energy Laboratory and was appointed by the U.S. Secretary of Energy to the National Petroleum Council. 

Lieuwen has authored or edited four books on combustion and over 400 scientific publications. He also holds nine patents, several of which are licensed to industry, and is founder of an energy analytics company, Turbine Logic, where he acts as chief technology officer.

In Lieuwen’s appointment announcement, President Cabrera said, “Tim’s extensive experience and knowledge of Georgia Tech makes him uniquely suited to lead our research enterprise as we search for a permanent EVPR. I am grateful for his willingness to serve the Institute during this period of remarkable growth, and I look forward to working with him and the rest of the team.”

The DART mission targeted the binary asteroid system where Dimorphos (the smaller secondary) orbits Didymos (the larger primary), to intentionally cause a spacecraft crash on Dimorphos. The collision, which occurred on September 26, 2022, was the first to demonstrate asteroid deflection by changing the asteroid's motion in space through kinetic impact. Astronomers monitored this event using ground- and space-based telescopes like the Hubble Telescope (HST). A recent Nature article, “Ejecta, From the DART-Produced Active Asteroid Dimorphos,” on which Hirabayashi is a co-author, documented HST’s detailed observations of the intense dust ejection generated by the impact. 

The Hera mission, launching in October 2024, will analyze the post-DART impact conditions of Didymos and Dimorphos by performing remote sensing observations and employing two CubeSats from its parent spacecraft, Hera. Hera will arrive at the asteroid in 2026. The Planetary Science Journal article, “The ESA Hera Mission: Detailed Characterization of the DART Impact Outcome and the Binary Asteroid Didymos, highlights the project's developments. 

Planetary defense is the primary reason for studying near-Earth asteroids (NEAs), particularly potentially hazardous objects (PHOs). While Didymos does not threaten the Earth, scientists want to prepare for the possibility that PHOs could hit the planet. Hera mission researchers can learn valuable information about the system's impact behavior. 

Hirabayashi, a co-investigator for the DART mission, said, “I was thrilled to apply my experience in the DART mission, and I’m honored to now be part of the Hera mission.” 

Specifically, Hirabayashi will analyze the mutual motion of the two asteroids in the Didymos binary system and provide detailed forecasts of the asteroids’ locations and velocities. During this investigation, he will use Georgia Tech’s high-performance computing system, Partnership for an Advanced Computing Environment (PACE). His results will also be used to quantify the system's post-DART impact behavior and develop new knowledge about planetary defense. 

“Dinosaurs were completely wiped out by an asteroid about 66 million years ago. There are many possible threats, and we need the capability to defend the Earth properly,” Hirabayashi explained. “Such capability includes performing detailed potential risk assessment in a limited time span and, if necessary, deflecting and disrupting PHOs with proper measurements.” 

Hirabayashi joined Georgia Tech in August 2023. His research concentration is in space operations, celestial mechanics, planetary science, and design and navigation. He works across the campus to explore lunar science at Georgia Tech’s Center for Lunar Environment and Volatile Exploration, one of the NASA/SSERVI nodes led by Thom Orlando in the College of Science’s School of Chemistry and Biochemistry. 

For the third straight year, the RotorJackets — Georgia Tech's drone racing team — were on the podium after the Collegiate Drone Racing Championship (CDRC). The two-time defending champions finished third in the competition, which drew more than 60 pilots from 16 schools nationwide.  

A multidisciplinary initiative, the Space RI brings together faculty, researchers, and students from across campus who share a passion for space exploration. Their combined research explores a broad array of space-related topics, all considered from a human perspective.

“Launching Georgia Tech’s Space Research Initiative reinforces our commitment to advancing our understanding of space and our universe,” said Executive Vice President for Research Chaouki Abdallah. “It is also a testament to Georgia Tech's unwavering dedication to pushing the limits of what is possible and to fostering innovations that benefit humankind.”

The symposium was organized by Glenn Lightsey, interim executive director of the Space RI, and the Space RI steering committee, which consists of representatives from the Georgia Tech Research Institute (GTRI) and the Colleges of Engineering, Computing, and Sciences, the Ivan Allen College of Liberal Arts, and the Scheller College of Business. The day began with remarks from Research leadership and an overview of the Space RI and its mission. “This is an exciting time for space exploration at Georgia Tech and across the world,” Lightsey said. “Space research is a critical part of solving our world’s most challenging problems and improving life for everyone on Earth.”

Space research and exploration yield many societal benefits that improve life on Earth and even foster economic growth. These advances include rapidly evolving technologies, improvements in medicine, and the development of enhanced materials — such as self-healing materials and those designed for extreme environments. Additionally, space research provides essential tools, data, and insights for climate scientists.

Sessions and panels throughout the day covered space science, space media, NASA’s Moon to Mars program, GTRI’s space research program, commercial space initiatives, and space in popular culture. A.C. Charania, NASA’s chief technologist and a Georgia Tech alumnus, delivered the keynote address. He shared insights into his work at NASA and Moon to Mars.

Following the symposium, the Space RI hosted a “star party” at the Georgia Tech Observatory. People of all ages gathered at the event, where they could use the observatory’s telescope to observe the moon, Jupiter, and the Orion Nebula, an immense cloud of dust and gas from which new stars are born.

“It was a clear night, and we were able to view the lunar terminator — the boundary where the sun is setting on the moon — which accentuates craters and mountains,” said Lightsey. “It was exciting to officially launch our initiative on a day when the world celebrated space exploration and the star party was a fantastic way to end our event.”

In July 2025, the Space RI will transition into one of Georgia Tech’s Interdisciplinary Research Institutes. Learn more about the initiative at space.gatech.edu.

In May 2023, shortly after the start of the fourth LIGO-Virgo-KAGRA observing run, the LIGO Livingston detector observed a gravitational-wave signal from the collision of what is most likely a neutron star with a compact object that is 2.5 to 4.5 times the mass of our Sun. Neutron stars and black holes are both compact objects, the dense remnants of massive stellar explosions.

What makes this signal, called GW230529, intriguing is that the mass of the heavier object falls within a possible mass-gap between the heaviest known neutron stars and the lightest black holes. The gravitational-wave signal alone cannot reveal the nature of this object, and future detections of similar events, especially those accompanied by bursts of electromagnetic radiation, could hold the key to solving this cosmic mystery.

"Gravitational waves offer an unprecedented glimpse into the cosmos, allowing us to study black holes and neutron stars at vast intergalactic distances," says Surabhi Sachdev, an assistant professor in the School of Physics at Georgia Tech and co-chair of the compact binary coalescence working group for the LIGO Scientific Collaboration. 

"These cosmic messengers are unveiling a surprising population of compact objects with masses that defy our previous understanding based solely on electromagnetic observations," Sachdev explains. "The latest in this list is GW230529, a compact object with a mass that falls within the theorized 'mass gap' between neutron stars and black holes – a region once thought to be devoid of such objects. The ability to peer through this new window is reshaping our knowledge of the densest objects in the universe."

The mass gap between neutron stars and black holes

Before the detection of gravitational waves in 2015, the masses of stellar-mass black holes were primarily found using x-ray observations while the masses of neutron stars were found using radio observations. The resulting measurements fell into two distinct ranges with a gap between them from about 2 to 5 times the mass of our Sun. Over the years, a small number of measurements have encroached on the mass-gap, which remains highly debated among astrophysicists. 

Analysis of the signal GW230529 shows that it came from the merger of two compact objects, one with a mass between 1.2 to 2.0 times that of our Sun and the other slightly more than twice as massive. While the gravitational-wave signal does not provide enough information to determine with certainty whether these compact objects are neutron stars or black holes, it seems likely that the lighter object is a neutron star and the heavier object a black hole. Scientists in the LIGO-Virgo-KAGRA Collaboration are confident that the heavier object is within the mass gap.  

Gravitational-wave observations have now provided almost 200 measurements of compact-object masses. Of these, only one other merger may have involved a mass-gap compact object – the signal GW190814 came from the merger of a black hole with a compact object exceeding the mass of the heaviest known neutron stars and possibly within the mass gap. 

“With the observation of GW230529, comes excitement, not just for this observation, but future observations as well," says Megan Arogeti, a graduate student in the School of Physics at Georgia Tech working on post-merger signals from compact binary mergers. 

"With every observed gravitational wave signal with at least one neutron star progenitor, we have an opportunity to further our understanding of extremely dense nuclear matter," Arogeti says. "As our detector sensitivity increases, we can hope to observe more gravitational waves from the collision of neutron stars and black holes as well as the collision between two neutron stars, which could potentially feature a special postmerger signal allowing us to probe nuclear matter in a higher mass regime than we have been able to so far."
