One of the greatest obstacles is developing algorithms that remain robust and reliable despite these varying environmental factors.\u201d\u003C\/p\u003E\u003Cp\u003EThe team\u2019s algorithms will empower vehicles to independently assess their surroundings, identify safe paths, and select scientifically intriguing targets, all on their own. They also will allow the rovers to work together to explore or achieve other objectives.\u003C\/p\u003E\u003Cp\u003E\u0022Developing effective algorithms requires more than simply studying a standard vehicle and attempting to adapt autonomy solutions from there. That approach limits performance, particularly when driving at high speeds,\u201d Nakka said. \u201cTo achieve truly dynamic and responsive autonomous control, our algorithms must understand how the vehicle interacts with the terrain, control for uncertainty, and incorporate that surface to wheel contact information in real time.\u201d\u003C\/p\u003E\u003C\/div\u003E\u003C\/div\u003E\u003Cdiv\u003E\u003Cdiv\u003E\u003Ch3\u003E\u003Cstrong\u003ENext-Gen Robots for the Moon\u2019s Hidden Extremes\u003C\/strong\u003E\u003C\/h3\u003E\u003C\/div\u003E\u003C\/div\u003E\u003Cdiv\u003E\u003Cdiv\u003E\u003Cp\u003EAlongside control algorithms, Nakka and his team are crafting new robots capable of exploring harsh moon terrain and accessing challenging environments, such as lunar vents and caves.

Professor Carr taking a lead on that from a science perspective is important,\u201d says Seager, who will oversee two subsequent \u003Ca href=\u0022https:\/\/www.morningstarmissions.space\/\u0022\u003EMorning Star Missions to Venus\u003C\/a\u003E that the team envisions will culminate in an atmosphere sample return.\u003C\/p\u003E\u003Cp\u003EThe 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.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u201cIt was cool to see our instrument in action,\u201d says Snigdha Nellutla, a research engineer and data modeler, who recently finished her master\u2019s in aerospace engineering. She simulates the AFN\u2019s output in different environmental conditions, both during the Hawaii field tests and on the actual mission to Venus.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EIn Search of a Carbon Cycle\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u201cWe\u2019re seeking evidence of a carbon cycle in the Venus atmosphere,\u201d she said. \u201cLife 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?\u201d\u003C\/p\u003E\u003Cp\u003EBillions of years ago, Venus may have had as much water as Earth \u2014 but at some point in its evolution, carbon dioxide in the planet\u0027s atmosphere triggered an intense runaway greenhouse effect. This sent temperatures soaring, causing the planet\u0027s water to evaporate, and the hydrogen part of the water (H2O) was lost to space.\u003C\/p\u003E\u003Cp\u003EIn 2020, astronomers detected phosphine in Venus\u2019 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.\u003C\/p\u003E\u003Cp\u003EWhile Venus\u2019 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.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EThe Smoking Gun of Organics\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EThe mission to Venus will also measure fluorescence, considered \u201ca smoking gun\u201d for possible organic materials, says Carr.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EOn Venus\u2019 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.\u003C\/p\u003E\u003Cp\u003E\u201cThe differences with Venus\u2019s atmosphere compared with Earth have forced our whole team to look at how we approach astrobiology completely differently,\u201d he explains. \u201cWhen we think of finding signs of life, we follow the water, but Venus has no water; it\u2019s sulfuric acid.\u201d\u003C\/p\u003E\u003Cp\u003ETo Carr, the importance of the mission is to better understand Venus\u2019 chemistry, given that sulfuric acid and water have different properties, which can contribute to or limit the kind of chemistry that can occur.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u201cBy 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,\u201d 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.\u003C\/p\u003E\u003Cp\u003EVENUSIAN has enabled Georgia Tech aerospace engineering students to get a rare opportunity to test and model hardware that will fly in space.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EStudents Celebrate Teamwork, Space Aspirations \u0026nbsp;\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u201cAs a first-year, I\u2019ve had a variety of tasks, and that\u2019s been fun for me as someone who is just starting to explore my career possibilities,\u201d says Violet Oliver, who oversees the ground sampling tests. \u201cThis has been a really good introduction \u2014 getting my feet wet in what future space missions might look like and, more broadly, what the engineering test cycle looks like.\u201d\u003C\/p\u003E\u003Cp\u003E\u201cThe biggest thing we learned was how to work together as a team,\u201d adds Cassius Tunis, a senior in aerospace engineering.

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.\u003C\/p\u003E\u003Cp\u003EThe study found that the ejecta from the impact site on Dimorphos highly depends on the asteroid\u2019s 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\u2019s surface. The cloud of ejecta thus looks like a waffle cone. However, if the concrete wall\u2019s 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.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u201cThis changes the asteroid push dramatically. Dimorphos has a squashed round shape, like an M\u0026amp;M,\u201d Hirabayashi explained, \u201cIf 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.\u201d\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EFor the DART impact on Dimorphos, the study identified the impact scale and the asteroid\u2019s 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\u2019s rounded shape, and the net asteroid push by multiple impacts can be more efficient than the single impactor.\u003C\/p\u003E\u003Cdiv\u003E\u003Cp\u003E\u201cSending multiple smaller impactors not only results in a higher asteroid push but also potentially saves operational cost and \u0026nbsp;increases tactical flexibility for deflection,\u0022 Hirabayashi said.\u003C\/p\u003E\u003C\/div\u003E\u003Cp\u003EFerrari\u2019s study offered crucial information for Hirabayashi\u2019s conclusions. \u201cWe used Hubble Space Telescope\u2019s images and numerical simulations to quantify a viable mechanism of the ejecta evolution and successfully estimated ejected particles\u2019 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,\u201d Ferrari said. \u201cDocumenting how ejecta looks over time offers crucial insights into how the DART impact acted on ejecta, giving tight constraints on the target asteroid\u2019s properties.\u201d\u003C\/p\u003E\u003Cp\u003ENASA\u2019s DART mission was a success, and Hirabayashi\u2019s 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\u2019s 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.

Therefore, anything that grows on the slides will be identified as antibiotic-resistant to that particular antibiotic. Astronauts will then use a pipet to carefully extract DNA from a bacterial colony and sequence it using the Oxford Nanopore Technologies MinION, nanopore sequencing device, which will identify the microbe that is present, as well as sequence its entire genome in real-time.\u0026nbsp;\u201cIf we found a new organism that we\u2019ve never seen before, we\u2019d be able to detect it, sequence its entire genome, and determine how it might be resistant to different types of antibiotics,\u201d said Carr.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cdiv\u003E\r\n\u003Cdiv\u003E\r\n\u003Cp\u003EThis new technology will allow humans to travel further - and longer - into space without having to send data back to Earth for processing. \u201cFor the purposes of this study and to maximize the science yield, these bacteria will travel back to Earth,\u201d said \u003Cstrong\u003EJordan McKaig\u003C\/strong\u003E, PXL researcher and Ph.D. candidate in the EAS. \u201cThen we can study them more extensively to better reveal their genomic features, how they are adapting to the built environment, and understand the risks \u2013 if any -- they may pose to astronauts.\u201d\u003C\/p\u003E\r\n\u003C\/div\u003E\r\n\u003C\/div\u003E\r\n\r\n\u003Cdiv\u003E\r\n\u003Cdiv\u003E\r\n\u003Cp\u003EScientists and researchers at NASA Johnson will use this information to figure out what may make astronauts sick in space, how to optimize their health, and make plans for potential counter measures and treatments.

Additionally, there are questions about acoustic effects and how uneven heating will spread across a vehicle and potentially damage its structure.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;The airflow across a hypersonic vehicle can be both turbulent and laminar, different on different parts of the vehicle,\u0026rdquo; said Ahuja. \u0026ldquo;These wide variations of the flow properties can produce large variations in temperatures over the vehicle surface, which is highly undesirable with respect to the vehicle\u0026rsquo;s structural integrity. As such, we need to understand what is happening to the material as a result of temperature changes over time. This thermal loading cannot be studied in conventional wind tunnels, which normally offer fractions of seconds of run time at hypersonic conditions, because it takes a while for those conditions to become steady.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EAcoustic loading can also dramatically affect the structural integrity of a hypersonic vehicle, and that likewise requires time to evaluate. \u0026ldquo;Acoustic loading of the kind that could generate a crack in a structure that develops over time,\u0026rdquo; he said. \u0026ldquo;We could create and study these conditions with our flying testbed.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EFunding from GTRI\u0026rsquo;s Independent Research and Development (IRAD) program has supported the initiative so far, and by gathering enough data from the initial studies, Ahuja hopes to attract collaborators to help implement the new test approach.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;There is so much enthusiasm for this that I believe our chances of success are high,\u0026rdquo; he said. \u0026ldquo;By launching from another space system, we won\u0026rsquo;t have to worry about the initial launch propulsion.

Having a propulsion system will enable controllers to adjust the spacecraft\u0026rsquo;s distance from the lunar surface, allowing it to eventually get within 12 kilometers of the surface.

Infrasound, which cannot be heard by humans, is produced by tornados, earthquakes, explosions, wind turbines, the motion of large vehicles, aircraft and many other natural and human-created sources.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EInfrasound waves can travel long distances \u0026ndash; hundreds of miles \u0026ndash; and are largely unaffected by obstacles in their way. Generally defined as frequencies below 20 Hertz, infrasound has until now been detected and measured using arrays up to an acre in size that use hollow pipes or elements similar to garden soaker hoses to separate the sounds of interest from noise created by the wind.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EGTRI researchers have developed a novel infrasound analysis technique based on wavelet technology, a mathematical approach that represents a signal at different scales, using unique features at each scale. This technique, when applied to infrasound recordings, separates the wind noise from other signals of interest.

The most common way to achieve this has been to use long pipe arrays or large arrays of soaker hoses to gather the sound. The arrays allow pressure variations to be averaged over the length of the structure, thereby reducing the impact of the turbulent wind field. Other approaches to reduce wind noise use large tents covering the infrasound sensors, which also limits where they can be used.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe technique developed at GTRI uses smaller windscreens \u0026ndash; or no windscreens at all \u0026ndash; along with a wavelet denoising technique that breaks down the signal mathematically and then partitions out what is wind noise before reconstructing the remaining infrasound for analysis, explained Alessio Medda, a GTRI senior research engineer.

Karsai and Shrivastava collaborated with Yasemin Ozkan-Aydin, a postdoctoral research fellow in Goldman\u0026rsquo;s lab, to study the rover motion in the SCATTER test facility.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;By creating a small robot with capabilities similar to the RP15 rover, we could test the principles of locomoting with various gaits in a controlled laboratory environment,\u0026rdquo; Karsai said. \u0026ldquo;In our tests, we primarily varied the gait, the locomotion medium, and the slope the robot had to climb. We quickly iterated over many gait strategies and terrain conditions to examine the phenomena that emerged.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EIn the paper, the authors describe a gait that allowed the rover to climb a steep slope with the front wheels stirring up the granular material \u0026ndash; poppy seeds for the lab testing \u0026ndash; and pushing them back toward the rear wheels. The rear wheels wiggled from side-to-side, lifting and spinning to create a motion that resembles paddling in water. The material pushed to the back wheels effectively changed the slope the rear wheels had to climb, allowing the rover to make steady progress up a hill that might have stopped a simple wheeled robot.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe experiments provided a variation on earlier robophysics work in Goldman\u0026rsquo;s group that involved moving with legs or flippers, which had emphasized disturbing the granular surfaces as little as possible to avoid getting the robot stuck.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;In our previous studies of pure legged robots, modeled on animals, we had kind of figured out that the secret was to not make a mess,\u0026rdquo; said Goldman. \u0026ldquo;If you end up making too much of a mess with most robots, you end up just paddling and digging into the granular material. If you want fast locomotion, we found that you should try to keep the material as solid as possible by tweaking the parameters of motion.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EBut simple motions had proved problematic for Mars rovers, which got stuck in granular materials. Goldman says the gait discovered by Shrivastava, Karsai and Ozkan-Aydin might be able to help future rovers avoid that fate.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;This combination of lifting and wheeling and paddling, if used properly, provides the ability to maintain some forward progress even if it is slow,\u0026rdquo; Goldman said. \u0026ldquo;Through our laboratory experiments, we have shown principles that could lead to improved robustness in planetary exploration \u0026ndash; and even in challenging surfaces on our own planet.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe researchers hope next to scale up the unusual gaits to larger robots, and to explore the idea of studying robots and their localized environments together. \u0026ldquo;We\u0026rsquo;d like to think about the locomotor and its environment as a single entity,\u0026rdquo; Goldman said. \u0026ldquo;There are certainly some interesting granular and soft matter physics issues to explore.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThough the Mini Rover was designed to study lunar and planetary exploration, the lessons learned could also be applicable to terrestrial locomotion \u0026ndash; an area of interest to the Army Research Laboratory, one of the project\u0026rsquo;s sponsors.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026quot;This basic research is revealing exciting new approaches for locomotion in complex terrain,\u0026quot; said Dr. Samuel Stanton, program manager, Army Research Office, an element of the U.S. Army Combat Capabilities Development Command\u0026#39;s Army Research Laboratory. \u0026quot;This could lead to platforms capable of intelligently transitioning between wheeled and legged modes of movement to maintain high operational tempo.\u0026quot;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EBeyond those already mentioned, the researchers worked with Robert Ambrose and William Bluethmann at NASA, and traveled to NASA JSC to study the full-size NASA RP15 rover.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cem\u003EThis work was supported by the Army Research Office (W911NF-18-1-0120) and the NASA National Robotics Initiative (NNX15AR21G).

Early rapid growth of these halos prevented the formation of stars that would have competed with black holes for gaseous matter flowing into the area.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;In this study, we have uncovered a totally new mechanism that sparks the formation of massive black holes in particular dark matter halos,\u0026rdquo; Wise said. \u0026ldquo;Instead of just considering radiation, we need to look at how quickly the halos grow. We don\u0026rsquo;t need that much physics to understand it \u0026ndash; just how the dark matter is distributed and how gravity will affect that. Forming a massive black hole requires being in a rare region with an intense convergence of matter.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EWhen the research team found these black hole formation sites in the simulation they were at first stumped, said John Regan, research fellow in the Centre for Astrophysics and Relativity in Dublin City University. The previously accepted paradigm was that massive black holes could only form when exposed to high levels of nearby radiation.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;Previous theories suggested this should only happen when the sites were exposed to high levels of star-formation killing radiation,\u0026rdquo; he said. \u0026ldquo;As we delved deeper, we saw that these sites were undergoing a period of extremely rapid growth. That was the key. The violent and turbulent nature of the rapid assembly, the violent crashing together of the galaxy\u0026rsquo;s foundations during the galaxy\u0026rsquo;s birth prevented normal star formation and led to perfect conditions for black hole formation instead. This research shifts the previous paradigm and opens up a whole new area of research.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe earlier theory relied on intense ultraviolet radiation from a nearby galaxy to inhibit the formation of stars in the black hole-forming halo, said Michael Norman, director of the San Diego Supercomputer Center at UC San Diego and one of the work\u0026rsquo;s authors. \u0026ldquo;While UV radiation is still a factor, our work has shown that it is not the dominant factor, at least in our simulations,\u0026rdquo; he explained.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe research was based on the Renaissance Simulation suite, a 70-terabyte data set created on the Blue Waters supercomputer between 2011 and 2014 to help scientists understand how the universe evolved during its early years. To learn more about specific regions where massive black holes were likely to develop, the researchers examined the simulation data and found ten specific dark matter halos that should have formed stars given their masses but only contained a dense gas cloud. Using the Stampede2 supercomputer, they then re-simulated two of those halos \u0026ndash; each about 2,400 light-years across \u0026ndash; at much higher resolution to understand details of what was happening in them 270 million years after the Big Bang.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;It was only in these overly-dense regions of the universe that we saw these black holes forming,\u0026rdquo; Wise said. \u0026ldquo;The dark matter creates most of the gravity, and then the gas falls into that gravitational potential, where it can form stars or a massive black hole.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe Renaissance Simulations are the most comprehensive simulations of the earliest stages of the gravitational assembly of the pristine gas composed of hydrogen and helium and cold dark matter leading to the formation of the first stars and galaxies. They use a technique known as adaptive mesh refinement to zoom in on dense clumps forming stars or black holes. In addition, they cover a large enough region of the early universe to form thousands of objects\u0026mdash;a requirement if one is interested in rare objects, as is the case here. \u0026ldquo;The high resolution, rich physics and large sample of collapsing halos were all needed to achieve this result,\u0026rdquo; said Norman.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe improved resolution of the simulation done for two candidate regions allowed the scientists to see turbulence and the inflow of gas and clumps of matter forming as the black hole precursors began to condense and spin. Their growth rate was dramatic.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;Astronomers observe supermassive black holes that have grown to a billion solar masses in 800 million years,\u0026rdquo; Wise said. \u0026ldquo;Doing that required an intense convergence of mass in that region. You would expect that in regions where galaxies were forming at very early times.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EAnother aspect of the research is that the halos that give birth to black holes may be more common than previously believed.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;An exciting component of this work is the discovery that these types of halos, though rare, may be common enough,\u0026rdquo; said Brian O\u0026rsquo;Shea, a professor at Michigan State University.\u0026nbsp; \u0026ldquo;We predict that this scenario would happen enough to be the origin of the most massive black holes that are observed, both early in the universe and in galaxies at the present day.\u0026rdquo;\u0026nbsp; \u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EFuture work with these simulations will look at the lifecycle of these massive black hole formation galaxies, studying the formation, growth and evolution of the first massive black holes across time. \u0026ldquo;Our next goal is to probe the further evolution of these exotic objects. Where are these black holes today? Can we detect evidence of them in the local Universe or with gravitational waves?\u0026rdquo; Regan asked.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EFor these new answers, the research team \u0026ndash; and others \u0026ndash; may return to the simulations.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;The Renaissance Simulations are sufficiently rich that other discoveries can be made using data already computed,\u0026rdquo; said Norman. \u0026ldquo;For this reason we have created a public archive at SDSC containing called the Renaissance Simulations Laboratory where others can pursue questions of their own.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cem\u003EThis research was supported by the National Science Foundation through grants PHY-1430152, AST-1514700, AST-161433 and OAC-1835213, by NASA grants NNX12AC98G, 147 NNX15AP39G, and NNX17AG23G, and by Hubble theory grants HST-AR-13261.01, HST-AR-14315.001, and HST-AR-14326.

Earth.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe observations, made by the IceCube Neutrino Observatory at the Amundsen\u0026ndash;Scott South Pole Station and in coordination with telescopes around the globe and in Earth\u0026rsquo;s orbit, help resolve a more than a century-old riddle about what sends subatomic particles such as neutrinos and cosmic rays speeding through the universe.\u003C\/p\u003E\r\n\r\n\u003Cp\u003ESince they were first detected over one hundred years ago, cosmic rays\u0026mdash;highly energetic particles that continuously rain down on Earth from space\u0026mdash;have posed an enduring mystery: What creates and launches these particles across such vast distances? Where do they come from?\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EBecause cosmic rays are charged particles, their paths cannot be traced directly back to their sources due to the magnetic fields that fill space and warp their trajectories. But the powerful cosmic accelerators that produce them will also produce neutrinos. Neutrinos are uncharged particles, unaffected by even the most powerful magnetic field. Because they rarely interact with matter and have almost no mass\u0026mdash;hence their sobriquet \u0026ldquo;ghost particle\u0026rdquo;\u0026mdash;neutrinos travel nearly undisturbed from their accelerators, giving scientists an almost direct pointer to their source.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003ETwo papers published July 13 in the journal \u003Cem\u003EScience\u003C\/em\u003E have for the first time provided evidence for a known blazar as a source of high-energy neutrinos detected by the National Science Foundation-supported IceCube observatory. This blazar, designated by astronomers as TXS 0506+056, was first singled out following a neutrino alert sent by IceCube on September 22, 2017.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;The evidence for the observation of the first known source of high-energy neutrinos and cosmic rays is compelling,\u0026rdquo; said Francis Halzen, a University of Wisconsin\u0026ndash;Madison professor of physics and principal investigator for the IceCube Neutrino Observatory.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;The era of multi-messenger astrophysics is here.

A signature feature of blazars is that twin jets of light and elementary particles, one of which is pointing to Earth, are emitted from the poles along the axis of the black hole\u0026rsquo;s rotation.

Determine Routes of Respiratory Infectious Disease Transmission on Aircraft ","body":[{"value":"\u003Cp\u003EA recent study conducted by researchers from Emory University and the Georgia Institute of Technology found that an infectious passenger with influenza or other droplet-transmitted respiratory infection will most likely not transmit infection to passengers seated farther away than two seats laterally and one row in front or back on an aircraft. The study was designed to assess rates and routes of possible infectious disease transmission during flights.\u003Cbr \/\u003E\r\n\u0026nbsp;\u003Cbr \/\u003E\r\nCo-researchers Vicki Hertzberg, Ph.D., professor at Emory University\u0026#39;s\u0026nbsp;Nell Hodgson Woodruff School of Nursing and Howard Weiss, Ph.D., professor in the School of Mathematics at the Georgia Institute of Technology, led tracking efforts in their FlyHealthy(TM)\u0026nbsp;study, developing a model that combines estimated infectivity and patterns of contact among aircraft passengers and crew members to determine likelihood of infection.\u0026nbsp;\u0026nbsp;\u003Cbr \/\u003E\r\n\u0026nbsp;\u003Cbr \/\u003E\r\nFlyHealthyTM team members were assigned to monitor specific areas of the passenger cabin, and made five round trips from the East to West Coast recording movements of passengers and crew. In addition, they collected air samples and obtained surface samples from areas most likely to harbor microbes. They leveraged the movement data to create thousands of simulated flight scenarios and possibilities for direct exposure to droplet-transmitted respiratory diseases.\u0026nbsp;\u003Cbr \/\u003E\r\n\u0026nbsp;\u003Cbr \/\u003E\r\n\u0026ldquo;Respiratory diseases are often spread within populations through close contact,\u0026rdquo; explained\u0026nbsp;Hertzberg. \u0026ldquo;We wanted to determine the number and duration of social contacts between passengers and crew, but we could not use our regular tracking technology on an aircraft. With our trained observers, we were able to observe where and when contacts occurred on flights. This allows us to model how direct transmission might occur.\u0026rdquo;\u003Cbr \/\u003E\r\n\u0026nbsp;\u003Cbr \/\u003E\r\n\u0026ldquo;We now know a lot about how passengers move around on flights. For instance, around 40 percent of passengers never leave their seats, another 40 percent get up once during the flight, and 20 percent get up two or more times. Proximity to the aisle was also associated with movement. About 80 percent of passengers in aisle seats got up during flights, in comparison to 60 percent of passengers in middle seats and 40 percent in window seats. Passengers who leave their seats are up for an average of five minutes.\u0026rdquo;\u003Cbr \/\u003E\r\n\u0026nbsp;\u003Cbr \/\u003E\r\nResearchers also noted fomite transmission \u0026ndash; exposure to viruses that remain on certain surfaces such as tray tables, seat belts and lavatory handles \u0026ndash; as additional likely contributors to disease transmission. They provide public health recommendations to help prevent the spread of infectious disease.\u003Cbr \/\u003E\r\n\u0026nbsp;\u003Cbr \/\u003E\r\n\u0026ldquo;We found that direct disease transmission outside of the one-meter area of an infected passenger is unlikely,\u0026rdquo; explained\u0026nbsp;Weiss. Respiratory infections can also be transmitted indirectly through contact with an infected surface. This could happen if a sick passenger coughs into their hand, and later touches a lavatory surface or overhead bin handle. \u0026ldquo;Passengers and flight crews can eliminate this risk of indirect transmission by exercising hand hygiene and keeping their hands away from their nose and eyes.\u0026rdquo;\u003Cbr \/\u003E\r\n\u0026nbsp;\u003Cbr \/\u003E\r\nThe study, which was funded in partnership with aerospace leader Boeing, evaluated only the potential spread of infectious agents on an aircraft.

The first initiative with the Navy is to identify technology that will help integrate unmanned aerial vehicles into air control systems by providing miniaturized identification friend or foe (IFF) systems. IFF systems are already used in piloted aircraft, but the much smaller unmanned aircraft lack the space or power for conventional systems.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;Traditionally the Department of Defense (DoD) has been limited in the means and speed at which it could bring new technologies to the warfighter,\u0026rdquo; said Rob \u0026ldquo;Radar\u0026rdquo; Winston, a GTRI principal research engineer who directs the IMPAX program near Pax River Naval Air Station in Maryland. \u0026ldquo;Our adversaries aren\u0026rsquo;t constrained by cumbersome procurement rules and regulations.

These can include small- and medium-sized businesses, companies that don\u0026rsquo;t traditionally work with the military or bid on billion-dollar DoD procurements. Winston and his team work on the Navy\u0026rsquo;s behalf, matching warfighter needs with technology that may already exist \u0026ndash; or that can be developed to meet the needs.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe relationship between GTRI and NAVAIR\u0026rsquo;s Naval Air Warfare Center Aircraft Division (NAWCAD) is known as a partnership intermediary agreement (PIA).

We are going to be able to talk with these people to assess what they can contribute to the warfighter and do it all outside the gate and without the customary barriers.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EDoD agencies have their own research laboratories to help develop new technology, of course, but Winston\u0026rsquo;s group will tap other sources of innovation.

Members of GTRI\u0026rsquo;s UAV team visited each of the academies twice to work with the cadets and midshipmen.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;It was exciting and very rewarding to be able to work with the students on this project,\u0026rdquo; said Day. \u0026ldquo;They have a lot of demands on their time from their studies, so it was really hands-on and ambitious.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EIn addition to building and testing the aircraft and working with the students, GTRI also built seven NPS-designed launchers for the Zephyrs, which have a 54-inch wingspan. The launchers get the aircraft up to flight speed, accelerating the launch process \u0026mdash; which was part of the overall competition.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;To get them all into the air, you can\u0026rsquo;t spend more than about 30 seconds with each aircraft,\u0026rdquo; noted Day, who was part of the GTRI group that supported the competition on the ground at Camp Roberts.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;When you have 30 aircraft in the sky, it\u0026rsquo;s very different from when you only have five or 10,\u0026rdquo; he said. \u0026ldquo;There\u0026rsquo;s a higher level of stress because there are a lot more tasks to manage. We had a lot of lessons from our flight operations that we were able to share with the students.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EEarlier, Lee\u0026rsquo;s team built 65 Skywalker aircraft for the Low-Cost UAV Swarming Technology (LOCUST) program supported by the Office of Naval Research (ONR).\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EFlying in Simulation\u003C\/strong\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003EIn developing swarm tactics, GTRI relies heavily on simulation to prepare for actual flight tests. Computer time to run simulations is much less expensive than flying time, and allows for hundreds or thousands of test runs in the time that would be required for a single flight test.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;We can do testing in our laboratory using a variety of simulation tools and have the ability to run thousands of different scenarios, look at the results of different types of engagements, and then use machine learning techniques to hone in on new swarm-versus-swarm tactics,\u0026rdquo; said Don Davis, division chief of GTRI\u0026rsquo;s Robotics and Autonomous Systems Division. \u0026ldquo;In many cases, the simulation leads us to ideas we wouldn\u0026rsquo;t have thought of if we had been bound by human experience in this area.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EAmong the tools used by the service academy teams was SCRIMMAGE (Simulating Collaborative Robots in a Massive Multi-Agent Game Environment), developed by GTRI researchers led by senior research engineer Kevin DeMarco. SCRIMMAGE allows the interactions of tens, hundreds, or even thousands of air vehicles to be studied simultaneously. The system\u0026rsquo;s interface was designed to be familiar to anyone who has played video games.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;We can run the simulations faster than real time, so we can apply modern techniques that require much more data,\u0026rdquo; said DeMarco. \u0026ldquo;We developed SCRIMMAGE to allow users to see exactly how a new algorithm is affecting an aircraft\u0026rsquo;s flight maneuvers. We can run it on high-performance computing clusters to conduct millions of simulations and then have our machine-learning algorithms process that data to improve the algorithms.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe simulator doesn\u0026rsquo;t run on the real aircraft, but does use the aircraft control software as part of its testing.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EOne of the combat tactics developed on SCRIMMAGE and used by the Service Academies Swarm Challenge aircraft is called \u0026ldquo;Greedy Shooter.\u0026rdquo; Each UAV equipped with the software can locate the nearest enemy and go after it. The algorithm doesn\u0026rsquo;t rely on collaboration among air vehicles, so multiple aircraft might attack the same enemy.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;In SCRIMMAGE, we have shown that you get a 50 percent success rate with this,\u0026rdquo; said DeMarco.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EBut another algorithm developed by senior research scientist Charles Pippin allows the air vehicles to allocate tasks, much as a human team may divide up the work that needs to be done on a project. \u0026ldquo;The vehicles can negotiate among themselves and decide who will be assigned to each target. There is no specific leader, but in a decentralized way, the aircraft make those decisions,\u0026rdquo; DeMarco explained.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EIn the Swarm Challenge, each of the vehicles had information about all of the other vehicles, but in real combat situations, that wouldn\u0026rsquo;t be the case. SCRIMMAGE is helping GTRI researchers determine how much information is needed to gain improvements from the task allocation model.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EGTRI researchers are also comparing the swarm strategies against a legacy system \u0026mdash; the old-fashioned \u0026ldquo;wingman\u0026rdquo; approach in which two aircraft work as a team. That simple approach has advantages over more complicated algorithms even when computers are tracking all the air vehicles.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;Lots of agents running simple algorithms can make swarms look more intelligent than they actually are,\u0026rdquo; DeMarco said. \u0026ldquo;Our hypothesis is that by being able to solve the two-versus-two challenge, we may be able to extend what we learn to a swarm.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EThe Competition and Outcome\u003C\/strong\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003EAt the three-day competition, service academy teams faced off against each other inside a \u0026ldquo;Battle Cube,\u0026rdquo; a three-dimensional airspace 500 meters on a side and 78 meters above the ground. Each team was given 20 fixed-wing UAVs and 20 quadcopters and, under the Challenge rules, could select a mix of 25 vehicles (with five in reserve, for a total of 30) for each of two 30-minute battle rounds.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EEach team had to defend its flag \u0026mdash; a large, inflatable ground target \u0026mdash; while trying to score the most points. Points could be awarded in three ways: physically landing a UAV on the opponent\u0026rsquo;s flag, simulated firing on an opponent\u0026rsquo;s UAV, and launching as many aircraft as possible.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe U.S. Naval Academy was declared the winner of the competition. (Full information about the event is available at \u003Ca href=\u0022http:\/\/www.darpa.mil\/news-events\/2017-05-11\u0022\u003Ewww.darpa.mil\/news-events\/2017-05-11\u003C\/a\u003E).\u003C\/p\u003E\r\n\r\n\u003Cp\u003EIn addition to helping advance swarm tactics, the competition also helped the next generation of Air Force, Army, and Navy leaders get a head start on future swarm technology.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;This competition wasn\u0026rsquo;t as much about who won and who lost as it was about offering hands-on insights about this quickly evolving and increasingly important technology,\u0026rdquo; said Davis. \u0026ldquo;GTRI is pleased to help train and equip the next generation of warfighters. Together, we showed that it is possible to get swarms of vehicles in the air and into mock combat against each other.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EAmong the lessons learned was the importance of rapidly launching the aircraft. Davis said the team able to get into the air first had an advantage over others. The competition also stretched the wireless networks used to communicate among the aircraft, and that will need improvement in the future.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;The biggest surprise to me was how well everything worked and how well the swarms operated,\u0026rdquo; Davis said. \u0026ldquo;This is another step in developing the knowledge and experience required to use UAV swarms in the field. There\u0026rsquo;s a lot more that needs to be done, but we\u0026rsquo;re making progress.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EIn the future, highly autonomous vehicles could ultimately find uses throughout the military.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;UAVs will be extending the capabilities of the warfighter,\u0026rdquo; Davis said. \u0026ldquo;I don\u0026rsquo;t think we should expect swarms of UAVs to primarily just replace people.

For the project with CNN, GTRI provides pilots to fly the drones in approved areas, plans the flight tests with CNN\u2019s participation, collects data, and prepares reports with recommendations.\u003C\/p\u003E\u003Cp\u003EOne of CNN\u2019s takeaways from the flight tests: Drone journalism is no one-person show. \u201cIn most cases, especially for live video, you need three people,\u201d Agvent said. This includes a pilot to guide the actions of the UAV and an operator for the camera, which is usually suspended under the drone and sits on gimbals for stabilization.\u003C\/p\u003E\u003Cp\u003E\u201cThe third person, a spotter, is particularly important in urban areas,\u201d Agvent continued. \u201cThe spotter focuses solely on situational awareness and communicates to the pilot about people and other aircraft that may be in the area. In some cases, you could get by with a two- person team \u2014 a pilot\/cameraman and a spotter \u2014 but a trio is best to ensure both high quality and safety.\u201d\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EAdvancing to Operational Protocols\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u201cWe\u2019ve hit a lot of milestones in the past year,\u201d Agvent said. \u201cNow, we begin to work on the finer points of flight operations and coordinating with air traffic control.\u201d\u003C\/p\u003E\u003Cp\u003EOne of the FAA\u2019s chief concerns with drones is getting the word out to manned aircraft about a UAV\u2019s presence in the area. The current practice is to file a \u201cnotice to airmen\u201d two or three days in advance.\u003C\/p\u003E\u003Cp\u003EA new technology known as automatic dependent surveillance-broadcast (ADS-B) could provide a just-in-time alternative to the notice to airmen. Developed by the FAA, this technology enables aircraft to broadcast their GPS coordinates to anyone in the local air space that has ADS-B, and vice-versa, so the drone operator would be able to see other aircraft.\u003C\/p\u003E\u003Cp\u003E\u201cIt\u2019s like having an air traffic radar map inside your cockpit,\u201d Heiges said. \u201cEven better, unlike conventional radar, ADS-B works all the way to the ground.\u201d That\u2019s important, because, in some situations, journalists may need to cooperate with police helicopters or medical aircraft flying at low altitudes to pick up patients.\u003C\/p\u003E\u003Cp\u003EGeo-fencing technologies, which prevent UAVs from entering airport and other restricted areas, could add another layer of safety, Heiges added.\u003C\/p\u003E\u003Cp\u003EBecause FAA rules prohibit drones from flying over people, crowd-control issues must also be resolved. For example, are journalists responsible for blocking off the area where they wish to fly drones \u2014 or do they communicate with on-scene commanders to find out where they can operate?\u003C\/p\u003E\u003Cp\u003EOver the next few months, GTRI and CNN will meet with regional emergency responders and other stakeholders to address these questions and develop an operational framework. Then GTRI will work with law enforcement agencies to test the procedures at remote locations. \u201cWe\u2019ll hold mock trials and simulate circumstances that would happen in a breaking news situation,\u201d Heiges explained.\u003C\/p\u003E\u003Cp\u003ECreating appropriate regulations for various types of UAV flights is important, as the flight landscape has changed dramatically in recent years.\u003C\/p\u003E\u003Cp\u003E\u201cWhen people built radio-controlled airplanes out of balsa wood, they learned the rules for flying and flew aircraft at sanctioned sites,\u201d Heiges said. \u201cYet in the past few years, we now have multi-rotors and quad-rotors with automatic stabilization that don\u2019t require the same skills. People are flying them out of the box without knowing the rules. That can be dangerous if flown beyond visual range. Any significant accident will set back the industry, punishing those who do follow the rules.\u201d\u003C\/p\u003E\u003Cp\u003EEven small drones could cause a helicopter or aircraft to go down if it gets caught in a propeller or pulled into an engine. Indeed, drones have been in the news this past summer for interfering with firefighting efforts in California, including a San Bernadino wildfire where drones operated by curious hobbyists caused fire pilots to pull out of the fray for 30 minutes, allowing the fire to spread.\u003C\/p\u003E\u003Cp\u003E\u201cThe one thing that doesn\u2019t get talked about enough is the differentiation between hobbyists and commercial drone users \u2014 and that most of the problems are caused by laymen,\u201d said Agvent. \u201cOur goal is to create a framework that allows for safe integration of commercial drones for newsgathering. It\u2019s about having trusted vendors, trusted aircraft, and trusted procedures in place to act in a safe manner.\u201d\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EResearch News\u003C\/strong\u003E\u003Cbr \/\u003E\u003Cstrong\u003EGeorgia Institute of Technology\u003C\/strong\u003E\u003Cbr \/\u003E\u003Cstrong\u003E177 North Avenue\u003C\/strong\u003E\u003Cbr \/\u003E\u003Cstrong\u003EAtlanta, Georgia 30332-0181 USA\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EMedia Relations Contact\u003C\/strong\u003E: John Toon (404-894-6986) (\u003Ca href=\u0022mailto:jtoon@gatech.edu\u0022\u003Ejtoon@gatech.edu\u003C\/a\u003E)\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EWriter\u003C\/strong\u003E: T.J.

Tensile strength expresses how much force is required to actually break the material.\u003C\/p\u003E\u003Cp\u003EIn gel spinning, the solution is first converted to a gel; this technique binds polymer chains together and produces robust inter-chain forces that increase tensile strength. Gel spinning also increases directional orientation of fibers, which also augments strength. By contrast, in conventional solution spinning, a process developed more than 60 years ago, PAN co-polymer solution is directly converted to a solid fiber without the intermediate gel state and produces less-robust material.\u003C\/p\u003E\u003Cp\u003EThe gel-spun carbon fiber produced by Kumar\u2019s team was tested at 5.5 to 5.8 gigapascals (GPa) \u2013 a measure of ultimate tensile strength \u2013 and had a tensile modulus in the 354-375 GPa range.

The Atlanta-area students work in teams, advised by Georgia Tech research scientists and graduate students who serve as mentors.\u003C\/p\u003E\u003Cp\u003E\u201cInterest in the program has been strong all spring, and applications have come in at a pretty high rate,\u201d said Kelly Griendling, a Georgia Tech research engineer who designed and directed the STEP program. \u201cI\u0027ve gotten a lot of emails that basically say, \u2018I heard from my friend that this was a great program, and I\u0027d like to do it.\u2019 \u201d\u003C\/p\u003E\u003Cp\u003ELast summer\u2019s two-month program, she explained, dropped a wide range of knotty aerospace and vehicle related problems into the laps of student teams. The teams worked on portions of these real-world projects, and what the students achieved went to advance those projects. The students could ask for help from their mentors when necessary, but most of the time they worked on their own.\u003C\/p\u003E\u003Cp\u003EKelly Ingle, a teacher at Kennesaw Mountain High School who is familiar with STEP, believes that the students who participated in last summer\u2019s program experienced \u201creal life,\u201d gaining independence, improving problem-solving abilities, and learning to be team players in actual research.\u003C\/p\u003E\u003Cp\u003E\u201cI have two students in my current classes who attended STEP last summer,\u201d Ingle said. \u201cWatching their approach to research this semester, it\u2019s evident to me that the STEP experience was beneficial.\u201d\u003C\/p\u003E\u003Cp\u003EThe atmosphere in the STEP research laboratories last summer seemed both highly enthusiastic and very serious.

The team has also completed a design for a deployable mid-size bathymetric device that is less than half the size and weight of current systems and needs half the electric power.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EMeasuring Laser Light\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003ETo simulate the movement of an actual aircraft, the prototype must be \u0022flown\u0022 over a laboratory pool. To do this, the researchers install the lidar onto a gantry above a large water tank in Georgia Tech\u2019s Woodruff School of Mechanical Engineering and then operate it in a manner that simulates flight.\u003C\/p\u003E\u003Cp\u003EThe lidar utilizes a high-power green laser that can penetrate water to considerable depths. Firing a laser beam every 10,000th of a second, the proxy aircraft allows the team to study the best methods for producing accurate images of objects on the floor of the pool.\u003C\/p\u003E\u003Cp\u003EThe ultimate goal is to obtain accurate reflectance from the sea floor, but the presence of water makes that difficult. To capture good images, the GTRI lightweight lidar must make a series of adjustments that let it measure reflected laser beams as if there were no water present.\u003C\/p\u003E\u003Cp\u003EOne challenge is that when a tightly focused light beam such as a laser hits water, it loses speed and bends, a familiar underwater effect called refraction. Due to changes in the water\u0027s surface, the angle of refraction varies constantly, and these changes in the refracted angle must be accounted for when computing the path of the light.\u003C\/p\u003E\u003Cp\u003EAnother challenge is that the photons in the laser beam scatter in the water, like light from a car headlight hitting fog. The amount of this scattering depends on the water\u2019s turbidity, which refers to the number of particles suspended in it. In addition, the water absorbs some of the light.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EBecause of these two effects, a lidar system receives back only a tiny signal when its laser beam bounces off an underwater surface such as the sea floor. The signal-conditioning and sensor-processing capabilities of the lightweight lidar must be sophisticated enough to detect that small returning signal in an overall sea and air environment that is very noisy \u2013 meaning that it\u0027s filled with extraneous signals that interfere with the desired data.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EImproving Critical Techniques\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EThe ultimate product of a bathymetric lidar is a three-dimensional point cloud that describes the seafloor at high spatial resolution. Users of these data need to know the accuracy of each point.\u003C\/p\u003E\u003Cp\u003EGTRI\u2019s researchers have devised a new approach for accuracy assessment called total propagated uncertainty (TPU). Using statistics, calculus, and linear algebra, the TPU technique propagates errors from the individual measurements \u2013 navigation, distance, and refraction angle \u2013 to estimate the accuracy of sea-floor measurements.\u003C\/p\u003E\u003Cp\u003EIn a major milestone, the GTRI team was the first to demonstrate bathymetric lidar coordinate computation and TPU estimates in real time. To achieve the necessary processing speed, the team employs a mixed-mode computing environment composed of field programmable gate arrays (FPGAs), along with central-processing and graphics-processing units.\u003C\/p\u003E\u003Cp\u003EEach time a laser is fired, Tuell explained, it takes only a few nanoseconds for the beam to reach the bottom of the pool and bounce back. Once the beam returns, the lidar\u0027s high-speed computer digitizes the returned beam and computes ranges, coordinates, and TPU before the next shot of the laser.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0022In our laboratory tests, we\u0027re computing about 37 million points per second \u2013 which is exceptionally fast for a lidar system and gives us a great deal of information about the sea floor in a very short period of time,\u0022 Tuell said. \u0022The key is we\u0027re using FPGAs to do the necessary signal conditioning and signal processing, and we\u0027re doing it at exactly the time that we convert from an analog signal to a digital signal.\u0022\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EA Deployable Design\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EIn addition to developing the proof-of-concept lidar prototype, the GTRI team has produced a CAD design for a deployable bathymetric device that is half the size and weight of current devices and has lower power needs. The immediate goal is to field such a mid-size device on a larger UAV such as an autonomous helicopter.\u003C\/p\u003E\u003Cp\u003EThe longer-term aim is to use AEO-ISR technology to develop bathymetric lidars that could fly on small UAVs with payloads of 30 pounds or less. To help these lidars deliver maritime surveillance and mapping data in real time, most of the necessary signal processing would be done on the aircraft and only essential data would be transmitted to ground stations.\u003C\/p\u003E\u003Cp\u003E\u0022We\u0027ve provided a prototype that demonstrates the key technology, and we\u0027ve completed a design for a mid-size design,\u0022 Tuell said. \u0022In the future, we believe small bathymetric lidars will perform military tasks, and also civilian tasks such as county-level mapping, with increased convenience and at greatly reduced cost.\u0022\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EResearch News\u003C\/strong\u003E\u003Cbr \/\u003E\u003Cstrong\u003EGeorgia Institute of Technology\u003C\/strong\u003E\u003Cbr \/\u003E\u003Cstrong\u003E177 North Avenue\u003C\/strong\u003E\u003Cbr \/\u003E\u003Cstrong\u003EAtlanta, Georgia\u0026nbsp; 30332-0181\u0026nbsp; USA\u003C\/strong\u003E\u003Cbr \/\u003E\u003Cbr \/\u003E\u003Cstrong\u003EMedia Relations Contacts\u003C\/strong\u003E: Lance Wallace (404-407-7280) (\u003Ca href=\u0022mailto:lance.wallace@gtri.gatech.edu\u0022\u003Elance.wallace@gtri.gatech.edu\u003C\/a\u003E) or John Toon (404-894-6986) (\u003Ca href=\u0022mailto:jtoon@gatech.edu\u0022\u003Ejtoon@gatech.edu\u003C\/a\u003E).\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EWriter\u003C\/strong\u003E: Rick Robinson\u003Cbr \/\u003E\u003Cbr \/\u003E\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EA team at the Georgia Tech Research Institute (GTRI) has designed a new approach that could lead to underwater imaging lidars that are much smaller and more efficient than the current full-size systems.

study of thermonuclear X-ray bursts on neutron stars reveals that, on very rare occasions, shells can be expelled at relativistic speeds - up to 30 percent of the speed of light. These velocities are the highest ever measured for a cosmic thermonuclear event, including novae and thermonuclear supernovae. This phenomenon, discovered in only 0.1 second worth of data in 40 years of space-based X-ray astronomy, sheds new light on how nuclear flames spread over surfaces of neutron stars. The study was published by authors at the Georgia Institute of Technnology, SRON Netherlands Institute for Space Research and Anton Pannekoek Institute of the University of Amsterdam.\u003C\/p\u003E\u003Cp\u003EIn our galaxy, there are about 100 neutron stars that regularly burst in X-rays. When another star happens to be in the neighborhood of the neutron star, it may lose some of its hydrogen\/helium\u0026nbsp; atmosphere to it. This material on the surface of the neutron star subsequently ignites a thermonuclear runaway reaction resulting in a minutes-long X-ray burst. The bursts are so luminous that they are easily visible from anywhere in the galaxy, provided an X-ray detector is used in space because X-rays cannot penetrate the Earth\u2019s atmosphere.\u003C\/p\u003E\u003Cp\u003EX-ray bursts do not usually result in explosions. Gravity is so strong on the neutron star that any debris is firmly held tight to the surface. Only when a burst is powerful enough (in 20 percent of all cases), the pressure exerted by the radiation may be able to compensate for gravity. In such a case, the atmosphere is briefly lifted off the star and then pulled back again. The new study has now identified two bursts, out of more than 10,000 thus far detected, that are so powerful that a shell, visible for only a few tens of milliseconds, is flung loose from the star at 10 percent to 30 percent the speed of light..\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EGeorgia Tech physics postdoctoral researcher Laurens Keek is a secondary author on the paper. He says the two explosions were powered by helium fusion.\u003C\/p\u003E\u003Cp\u003E\u201cHelium burning produces a tiny amount of hydrogen,\u201d he added. \u201cThis acts as a catalyst, and our computer simulations show that nuclear burning speeds up more than 100 thousand times. It takes detailed knowledge of nuclear reactions to explain how these X-ray bursts could set the speed record.\u0022\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ERecord\u003C\/strong\u003E\u003Cbr \/\u003E \u0022The found bulk velocities are a record for nuclear-powered phenomena,\u0022 says SRON researcher, a primary author, Jean in \u0027t Zand. \u0022They are faster than the maxima measured in other stellar nuclear explosions (novae and type Ia supernovae). Presumably X-ray bursts provide us a window to the initial phase of thermonuclear runaways which is not available for (super)novae, since those are always discovered after that phase is over.\u0022\u003C\/p\u003E\u003Cp\u003EThe exceptional outflows seen in these two bursts go hand in hand with very fast ignitions of the complete neutron star surface \u2013 within less than 1 millisecond. In \u0027t Zand:\u0026nbsp; \u201cThis is very quick. It means that the nuclear flame spreads across the neutron star at velocities close to 0.1 times the speed of light. This puts interesting constraints on the theory of ignition and how the nuclear reaction chain works. Normal flame propagation mechanisms may not be viable in this regime. Instead, the neutron star atmosphere may be ignited in a so-called auto-ignition regime. In any case, this observational result is expected to stimulate new theoretical work.\u0022\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ENeutron stars\u003C\/strong\u003E\u003Cem\u003E\u003Cbr \/\u003E \u003C\/em\u003EOne can imagine a neutron star as a failed black hole. Both are remnants of stars at least a few times heavier than the sun, collapsed during a supernova after exhaustion of the nuclear fuel that kept them shining. Neutron stars are lighter than black holes, which makes them capable of making a full stop of the collapse just short of vanishing behind the event horizon, at a diameter of merely a few tens of kilometers. This implies that they have visible surfaces with unparalleled strong gravity, some 10,000 billion times stronger than on Earth. Throwing matter at it has a dramatic effect. That matter quickly piles up in a 1 m thick layer with such high pressures that a stellar sized H-bomb, powered by thermonuclear fusion, is ignited. The fusion lasts a fraction of a second and heats up the atmosphere to tens of millions of degrees. The subsequent cooling is visible as a minutes-long X-ray burst. The X-ray burst phenomenon was first discovered at SRON in 1975, with the first satellite built in the Netherlands (ANS).

The latest prototypes have been able to provide gain to 6 GHz, opening more communication options to the end user. For the flight test, GTRI collaborated with SR Technologies, Inc.

Because of its low power consumption, the A3 requires no cooling system.\u003C\/p\u003E\u003Cp\u003EThe Agile Aperture Antenna has also been tested on a Wave Glider autonomous ocean vehicle. Together with previous testing on a moving ground vehicle, the new evaluations demonstrate the operational flexibility of the antenna, Habib said.

It is assumed that UV light from nearby galaxies was too strong and suppressed these tiny neighbors.\u003C\/p\u003E\u003Cp\u003E\u201cIt turns out they did form stars, usually in one burst, around 500 million years after the Big Bang,\u201d said John Wise, a Georgia Tech assistant professor in the School of Physics who led the study. \u201cThe galaxies were small, but so plentiful that they contributed a significant fraction of UV light in the reionization process.\u201d\u003C\/p\u003E\u003Cp\u003EThe team\u2019s simulations modeled the flow of UV stellar light through the gas within galaxies as they formed. They found that the fraction of ionizing photons escaping into intergalactic space was 50 percent in small (more than 10 million solar masses) halos. It was only 5 percent in larger halos (300 million solar masses). \u0026nbsp;This elevated fraction, combined with their high abundance, is exactly the reason why the faintest galaxies play an integral role during reionization.\u003C\/p\u003E\u003Cp\u003E\u201cIt\u2019s very hard for UV light to escape galaxies because of the dense gas that fills them,\u201d said Wise. \u201cIn small galaxies, there\u2019s less gas between stars, making it easier for UV light to escape because it isn\u2019t absorbed as quickly.

The universe was fully ionized at 860 million years after its creation.\u003C\/p\u003E\u003Cp\u003E\u201cThat such small galaxies could contribute so much to reionization is a real surprise,\u201d said Michael Norman, distinguished professor of physics at UC San Diego and one of the co-authors of the paper. \u201cOnce again, the supercomputer is teaching us something new and unexpected; something that will need to be factored into future studies of reionization.\u201d\u003C\/p\u003E\u003Cp\u003EThe term reionized is used because the universe was ionized immediately after the fiery Big Bang. During that time, ordinary matter consisted of hydrogen atoms with positively charged protons stripped of their negatively charged electrons. Eventually, the universe cooled enough for electrons and protons to combine and form neutral hydrogen. They didn\u2019t give off any optical or UV light. Without the light, astrophysicists aren\u2019t able to see traces of how the cosmos evolved during these Dark Ages using conventional telescopes. The light returned when reionization began, allowing experts like Wise to pinpoint the youngest galaxies and study their features.\u003C\/p\u003E\u003Cp\u003EThe research team expects to learn more about these faint galaxies when the next generation of telescopes is operational.

For non-reusable portions of the missile like the motor and warhead, the use of simulation models makes it possible to run thousands of test cycles without leaving the laboratory, and for less than the cost of one live test.\u201d\u003C\/p\u003E\u003Cp\u003EWith current testing models, thermal signature databases must be computed offline prior to the test, and can take up to three days for a mere fifteen minutes of simulation time. Any alteration to the parameters\u2014altitude, weather, terrain, or even the position of the sun\u2014requires a total re-coding of the database. Testing a missile launch from Hawaii, for example, to intercept a target at a certain distance, altitude and speed takes a long time to calculate all of the missile hardware inputs that are used in the test.\u003C\/p\u003E\u003Cp\u003EWhat GTRI is working on, according to Parker, will enable the simulated components to be \u201clooped in\u201d for real-time calculation, eliminating the need for database computation ahead of time. Using off-the-shelf NVIDIA graphics cards, the group will work to provide the seeker with simulated thermally emissive ballistic targets heated by atmospheric effects in real time. The team will be using CUDA, NVIDIA\u2019s parallel computing architecture.\u003C\/p\u003E\u003Cp\u003E\u201cOur goal is to calculate and provide inputs at up to 200 Hz, which means simulated measurements are sent to the seeker unit 200 times each second,\u201d Parker said. \u201cThis will allow us to run dozens of tests in the amount of time we used to spend calculating data for a single run. Test parameters can be changed on the fly\u2014MDA will be able to run many more \u2018what if\u2019 scenarios before fielding a defense system.\u201d\u003C\/p\u003E\u003Cp\u003EAEgis Technologies in Huntsville is the prime contractor of the project. They will operate the Army-owned, hardware-in-the-loop test bed and generate scenarios for use in simulations.\u003C\/p\u003E\u003Cp\u003EGTRI provides the expertise in real-time computing. Prior to this, AEgis had worked indirectly with GTRI\u2019s Electro-Optical Systems Laboratory (EOSL) on the same program, which supported ultraviolet sensor testing.\u003C\/p\u003E\u003Cp\u003E\u201cWe selected GTRI based on what I knew of EOSL\u2019s capabilities, and their expertise in GPU technology,\u201d said AEgis Program Manager Dennis Bunfield. \u201cGTRI\u2019s CUDA expertise is a great value, and their expertise in verification and validation is invaluable.\u201d\u003C\/p\u003E\u003Cp\u003EThe system will be scalable, and the plan is to take what they learn from this project and use it elsewhere in the defense industry. The thermal solver aspect of the project, for example, will be useful for any simulation requiring a real-time solution for thermal image simulation.\u003C\/p\u003E\u003Cp\u003E\u201cI think with some enhancements to the code framework, the capabilities can be extended to generate signatures in other regions, such as UV, the visible spectrum and for LADAR,\u201d Bunfield said. \u201cAside from military applications, it could be possible to use the thermal solver to commercial and manufacturing applications, such as thermal analysis simulation.\u201d\u003C\/p\u003E\u003Cp\u003E\u201cWe\u2019re working with AEgis Technologies to best model and simulate firing and the performance of these missiles by providing scenario inputs at the true hardware rate,\u201d Parker said. \u201cOur main goal\u2014writing a massively parallel NVIDIA CUDA thermal differential equation solver\u2014will enable faster and more effective testing of high-cost components at hardware-in-the-loop testing centers.\u201d\u003Cbr \/\u003E\u003Cbr \/\u003E\u003Cstrong\u003EResearch News\u003C\/strong\u003E\u003Cbr \/\u003E\u003Cstrong\u003EGeorgia Institute of Technology\u003C\/strong\u003E\u003Cbr \/\u003E\u003Cstrong\u003E177 North Avenue\u003C\/strong\u003E\u003Cbr \/\u003E\u003Cstrong\u003EAtlanta, Georgia\u0026nbsp; 30332-0181\u003C\/strong\u003E\u003Cbr \/\u003E\u003Cbr \/\u003E\u003Cstrong\u003EMedia Relations Contacts\u003C\/strong\u003E: Lance Wallace (\u003Ca href=\u0022mailto:lance.wallace@gtri.gatech.edu\u0022\u003Elance.wallace@gtri.gatech.edu\u003C\/a\u003E) (404-407-7280) or John Toon (\u003Ca href=\u0022mailto:jtoon@gatech.edu\u0022\u003Ejtoon@gatech.edu\u003C\/a\u003E) (404-894-6986).\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EWriter\u003C\/strong\u003E: Robert Nesmith\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EGeorgia Tech Research Institute (GTRI) researchers are working with a Huntsville, Ala., company and the U.S. Missile Defense Agency (MDA) to test high-altitude missiles without ever firing a shot.\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Georgia Tech researchers are working with a Huntsville company to test high-altitude missiles."}],"uid":"27303","created_gmt":"2014-06-11 15:23:47","changed_gmt":"2016-10-08 03:16:33","author":"John Toon","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2014-06-11T00:00:00-04:00","iso_date":"2014-06-11T00:00:00-04:00","tz":"America\/New_York"},"extras":[],"hg_media":{"302681":{"id":"302681","type":"image","title":"Modeling and Simulation Testing","body":null,"created":"1449244592","gmt_created":"2015-12-04 15:56:32","changed":"1475895007","gmt_changed":"2016-10-08 02:50:07","alt":"Modeling and Simulation Testing","file":{"fid":"199590","name":"hwilcarco.jpg","image_path":"\/sites\/default\/files\/images\/hwilcarco_0.jpg","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/images\/hwilcarco_0.jpg","mime":"image\/jpeg","size":731941,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/hwilcarco_0.jpg?itok=qORJPxgL"}}},"media_ids":["302681"],"groups":[{"id":"1188","name":"Research Horizons"}],"categories":[{"id":"136","name":"Aerospace"},{"id":"147","name":"Military Technology"},{"id":"135","name":"Research"},{"id":"150","name":"Physics and Physical Sciences"}],"keywords":[{"id":"416","name":"GTRI"},{"id":"1834","name":"missile"},{"id":"95151","name":"Missile Defense Agency"},{"id":"95141","name":"missile technology"},{"id":"579","name":"modeling and simulation"},{"id":"167045","name":"simulation"}],"core_research_areas":[{"id":"39431","name":"Data Engineering and Science"},{"id":"39481","name":"National Security"}],"news_room_topics":[{"id":"71881","name":"Science and Technology"}],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EJohn Toon\u003C\/p\u003E\u003Cp\u003EResearch News\u003C\/p\u003E\u003Cp\u003E\u003Ca href=\u0022mailto:jtoon@gatech.edu\u0022\u003Ejtoon@gatech.edu\u003C\/a\u003E\u003C\/p\u003E\u003Cp\u003E(404) 894-6986\u003C\/p\u003E","format":"limited_html"}],"email":["jtoon@gatech.edu"],"slides":[],"orientation":[],"userdata":""}},"303411":{"#nid":"303411","#data":{"type":"news","title":"Solar photons drive water off the moon","body":[{"value":"\u003Cp\u003EWater is thought to be embedded in the moon\u2019s rocks or, if cold enough, \u201cstuck\u201d on their surfaces.

The simulations reconstruct the chain of events by which a stellar core, similar to the remnant of a tidally disrupted red giant star, might evolve under the gravitational tides of a massive black hole.\u003C\/p\u003E\u003Cp\u003E\u0022Calculating the messy interplay between hydrodynamics and gravity is feasible on a human timescale only with a supercomputer,\u0022 Cheng said. \u0022Because we have control over this virtual experiment and can repeat it, fast forward, or rewind as needed, we can examine the tidal disruption process from many perspectives. This in turn allows us to determine and quantify the most important physical processes at play.\u0022\u003C\/p\u003E\u003Cp\u003EThe research shows how supercomputer simulations complement and constrain theory and observation.\u003C\/p\u003E\u003Cp\u003E\u0022There are many situations in astrophysics where we cannot get insight into a sequence of events that played out without simulations.

This is contrary to our perception, based on earlier epochs of observation, that they are a relatively uniform class of events. We have yet to understand what causes these differences in observational appearance, and computer simulations are guaranteed to be an important part of this journey.\u0022\u003C\/p\u003E\u003Cp\u003E\u003Cem\u003E-- Written by Aaron Dubrow of the National Science Foundation.\u003C\/em\u003E\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003ESomewhere out in the cosmos an ordinary galaxy spins, seemingly at slumber.

The effort focuses on modifying the design of avionics software, especially the ways in which it interfaces with an aircraft\u0027s hardware and other software.\u003C\/p\u003E\u003Cp\u003EThe work is part of the U.S. Navy\u0027s Future Airborne Capability Environment (FACE\u2122) project. The Navy\u2019s FACE team is working with the FACE consortium, a government, industry and academia consortium managed by The Open Group\u00ae, to develop a new technical standard that governs how avionics software communicates with other avionics software and hardware components \u2013 to control aircraft sensors, effectors and other mission critical systems to deliver warfighting capability.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EGeorgia Tech\u2019s support of the FACE project is funded by the Naval Air Systems Command (NAVAIR) Air Combat Electronics Program Office (PMA-209) and the U.S. Army Aviation and Missile Research Development and Engineering Center (AMRDEC).

The FACE architecture specifies that designers use application programming interfaces (APIs) that are essentially a standardized software layer that translates between the application on one level and the other software applications, the operating system and hardware at other levels. The result is that designers can readily modify application software, integrate it back into the system, and expect it to work.\u0026nbsp;\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0022As long as you adhere to the standard software interfaces specified in the FACE Technical Standard, then changing the embedded application software to add capability to the system becomes straightforward,\u0022 Woods said. \u0022Any competent software engineer should be able to write an application that can talk to those interfaces, and that makes it possible to add in new capabilities quickly and easily.\u0022\u003C\/p\u003E\u003Cp\u003EGeorgia Tech expects to be involved in tests that will demonstrate to the Navy the portability of capabilities using the FACE Technical Standard, he added.\u003C\/p\u003E\u003Cp\u003EThe FACE Technical Standard takes advantage of the Portable Operating System Interface (POSIX), a group of open software standards aimed at making applications compatible with various operating systems.

But electronics in deep space are typically exposed to far greater temperature ranges, as well as to damaging radiation. The Moon\u0027s surface cycles between plus-120 Celsius during the lunar day to minus-180 Celsius at night. \u003C\/p\u003E\u003Cp\u003EThe silicon-germanium electronics developed by the extreme environments team has been shown to function reliably throughout that entire plus-120 to minus-180 Celsius range.

Designers must place most electronics in a protected, temperature controlled central location and then connect them via long and heavy cables to sensors or other external devices. \u003C\/p\u003E\u003Cp\u003EBy eliminating the need for most shielding and special cables, silicon-germanium technology helps reduce the single biggest problem in space launches -- weight. Moreover, robust SiGe circuits can be placed wherever designers want, which helps eliminate data errors caused by impedance variations in lengthy wiring schemes. \u003C\/p\u003E\u003Cp\u003E\u0022For instance, the Mars Exploration Rovers, which are no bigger than a golf cart, use several kilometers of cable that lead into a warm box,\u0022 Keys said. \u0022If we can move most of those electronics out to where the sensors are on the robot\u0027s extremities, that will reduce cabling, weight, complexity and energy use significantly.\u0022 \u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EA Collaborative Effort\u003C\/strong\u003E \u003C\/p\u003E\u003Cp\u003ENASA currently rates the new SiGe electronics at a technology readiness level of six, which means the circuits have been integrated into a subsystem and tested in a relevant environment.

The resulting SiGe device weighs about 200 grams and requires no temperature or radiation shielding. Large numbers of these robust, lightweight REU units could be mounted on spacecraft or data-gathering devices close to sensors, reducing size, weight, power and reliability issues. \u003C\/p\u003E\u003Cp\u003EBerger said that BAE Systems is interested in manufacturing a sensor interface device based on the extreme environment team\u0027s discoveries. \u003C\/p\u003E\u003Cp\u003EOther space-oriented companies are also pursuing the new silicon-germanium technology, Cressler said.

It also offers important reduced-noise benefits. \u003C\/p\u003E\u003Cp\u003EBased on this engine placement, the team\u0027s powered-lift design maximizes performance using several interrelated elements: \u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ENovel Blown-Wing Design\u003C\/strong\u003E \u003C\/p\u003E\u003Cp\u003EIn most fixed-wing aircraft, Englar explains, the upper surface of the wing is curved. That curvature forces air to flow faster over the top of the wing, which reduces pressure on the upper surface of the wing, increasing wing lift. Mechanical flaps increase aft curvature, enlarging the wing during take-off and landing, and augmenting lift by deflecting the ambient wind stream flowing over the wing. \u003C\/p\u003E\u003Cp\u003EBut the lift generated by conventional wings isn\u0027t sufficient for the low flight speeds and steep ascents and descents required by CESTOL aircraft. The essential element in such extreme lift is circulation control \/ blown-wing technology. This approach can far exceed mechanical flaps in achieving high lift coefficient (a lift coefficient is a number that relates an aircraft\u0027s total lift to its wing area and flight speed). \u003C\/p\u003E\u003Cp\u003EThe GTRI team has designed a blown wing that is relatively simple mechanically. Unlike a conventional wing, which uses multiple flap elements, GTRI\u0027s design uses only one small, relatively simple flap. \u003C\/p\u003E\u003Cp\u003EHowever, that single wing flap is used in tandem with a novel element based on circulation-control technology. A narrow slot, capable of pneumatically blowing out air, runs along the entire trailing edge of each wing, just above the flap. This system is powered by its own compressed air source located inside the wing. \u003C\/p\u003E\u003Cp\u003EThe wing flap, which forms a sharp trailing edge during level flight to reduce drag, rotates downward on take-off and landing. When thus rotated, it forms a highly curved aft surface; then air from the slot can be blown over that curved surface to generate high lift. \u003C\/p\u003E\u003Cp\u003EThis procedure, called flap-blowing, performs two functions: it increases air velocity over the top of the wing, and it deflects the ambient wind stream downward so that it curls under the wing. The combined forces generate a lift coefficient that can be two to four times higher than a conventional mechanical flap. \u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EEntraining Jet Exhaust\u003C\/strong\u003E \u003C\/p\u003E\u003Cp\u003ETo achieve even higher lift than flap-blowing alone, the GTRI design takes advantage of an additional phenomenon -- the interaction between the air coming from the wing slot and the exhaust of the plane\u0027s over-the-wing jet engines. \u003C\/p\u003E\u003Cp\u003EDuring take-off and landing, air flow from the slot interacts with the engine exhaust and pulls this powerful exhaust blast down onto the wing. This process, called entraining the exhaust, greatly increases the velocity of the air passing over the wing and results in highly augmented upward suction and lift. \u003C\/p\u003E\u003Cp\u003E\u0022This strategy allows an aircraft to be flying at a very low speed, while the wing is seeing much higher relative wind speeds on its curved upper surface due to this blowing and thrust-entraining combination,\u0022 Englar said. \u0022We have measured lift coefficients between 8.0 and 10.0 on these pneumatic powered-lift wings at a level flight condition during testing. The normal lift coefficient on a conventional wing at a similar flight condition is less than 1.0.\u0022 \u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EReduced Noise\u003C\/strong\u003E \u003C\/p\u003E\u003Cp\u003EThe benefit of an above-the-wing engine configuration is not limited to providing good short takeoff and landing (STOL) performance. It also provides two potential sources of noise reduction: engine-noise shielding and reduced noise footprint in the community. \u003C\/p\u003E\u003Cp\u003EGaeta explains the noise-shielding issue by noting that today\u0027s commercial jets have their engines under the wings. During take-off and approach, a great deal of noise from these jets propagates downward unimpeded, while engine sound that does travel upward bounces off the wing and then reflects downward. \u003C\/p\u003E\u003Cp\u003E\u0022By putting the noise source above the wing, there is the potential to shield the ground from engine noise, at least partially,\u0022 Gaeta said. \u003C\/p\u003E\u003Cp\u003EThe critical design choice in noise shielding involves where to place the engine relative to the wing, he explained. Closer to the wing helps take-off and landing performance, but it increases noise due to viscous rubbing of the jet exhaust stream acting along the wing upper surface. Further away from the wing is better from a noise perspective, but not as effective for take-off and landing performance. \u003C\/p\u003E\u003Cp\u003EFinally, to the extent that placing the engine above the wing can shield exhaust noise, the engine needs to be placed as far forward as possible because maximum jet noise occurs at the exhaust exit, Gaeta said. Moreover, all of these design choices must not detract from the crucial issue of cruise performance. \u003C\/p\u003E\u003Cp\u003EThe very nature of a STOL flight trajectory -- steep takeoff and approach angles -- offers another potential noise benefit. This trajectory keeps much of the offending noise closer to the airport environs. \u003C\/p\u003E\u003Cp\u003EExplained Gaeta: \u0022By virtue of steeper takeoff and approach angles, the STOL aircraft can potentially keep its most offending noise within the airport boundary because it is farther from the ground when it passes over communities.\u0022 \u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EResearch News \u0026amp;

CUSTD\u0027s current capabilities are based on extensive research and testing, including more than 50 test flights conducted at Fort Benning and other locations throughout the past year. \u003C\/p\u003E\u003Cp\u003EA demonstration opportunity such as the Robotics Rodeo, Pippin said, allows researchers to dramatize how well multiple autonomous robots can now collaborate. \u003C\/p\u003E\u003Cp\u003E\u0022It\u0027s hard to illustrate the effectiveness of collaborative interoperability and autonomy algorithms in a simulation,\u0022 he said. \u0022When onlookers see the technology demonstrated on hardware platforms, then it becomes very real.\u0022 \u003C\/p\u003E\u003Cp\u003EIn a typical CUSTD scenario, the two aircraft search for an existing target over a wide area. When one plane spots the target, it radios its location using GPS coordinates to the unmanned ground vehicle, which then finds its way around buildings and along roads to the target. \u003C\/p\u003E\u003Cp\u003EAt the same time, the unmanned air vehicle over the target can ask the second aircraft to fly to the target and use its sensors to further analyze the situation. Such flexibility can be important, Pippin said, because UAVs are often outfitted with different sensors due to weight and cost considerations. \u003C\/p\u003E\u003Cp\u003EOne technique that is still under development at GTRI -- and is proving valuable for vehicle collaboration -- is called market-based auctions, Pippin said. This approach uses an \u0022auction\u0022 type of algorithm that lets robotic vehicles \u0022bid\u0022 on a given task. Using this method, unmanned vehicles can autonomously divide up work on the spot in the most efficient way. \u003C\/p\u003E\u003Cp\u003EIn an auction-technology scenario, an unmanned air vehicle over a target might send out a bid to other nearby UAVs, asking which among those airplanes that are outfitted with a particular sensor is closest to the target. The UAV that best complies with both requirements \u2013 equipment and proximity -- wins the bid. \u003C\/p\u003E\u003Cp\u003EIn a GTRI experiment, unmanned air vehicles using a market-based approach reduced the travel required to complete a task by nearly 50 percent. The result was a substantial saving in both time and fuel. \u003C\/p\u003E\u003Cp\u003EWeiss explained that GTRI\u0027s CUSTD system is standards compliant, an important consideration in current defense-technology development. All GTRI autonomous-system designs now comply with the Standard Interface of the Unmanned Control System for NATO UAV interoperability (STANAG 4586) and with the Joint Architecture for Unmanned Systems (JAUS) scripting language. \u003C\/p\u003E\u003Cp\u003E\u0022By developing these systems to be STANAG and JAUS compliant, we\u0027re building in future interoperability with other unmanned systems produced by different vendors,\u0022 Weiss said. \u0022If upcoming systems are going to be able to communicate, as well as operate with the control-system designs now being developed, they\u2019ll need to be standards compliant.\u0022 \u003C\/p\u003E\u003Cp\u003EThe CUSTD system also makes use of FalconView\u2122, a Windows-based mapping application developed by GTRI for the Department of Defense. FalconView supports many map types, such as aeronautical charts, satellite images and elevation maps. FalconView can be used by a ground-based station to monitor and control the system. \u003C\/p\u003E\u003Cp\u003EIn the past several years, GTRI has been bringing autonomous vehicle research under one umbrella that includes all aspects of systems-payload, sensor, autonomy logic and collaborative operations. Research now also includes unmanned underwater vehicles and space vehicles. \u003C\/p\u003E\u003Cp\u003EThe Robotics Rodeo will consist of two separate events. The Extravaganza is open to the public. The Robotic Technology Observation, Demonstration and Discussion (RTOD2), closed to the public, allows research teams to demonstrate their technologies to government observers and contractors. \u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EResearch News \u0026amp;

GTRI researchers Michael J. Willis and Michael L. McGuire, working with Air Force scientist Charlie W. Clark, have patented a way to use digital circuitry to perform many functions formerly allotted to more-problematic analog chips. \n\u003C\/p\u003E\n\u003Cp\u003ESpecifically, the researchers have moved a critical operation -- the logarithmic transfer function -- from the analog to the digital domain. The logarithmic transfer function coordinates the input and output of a radar warning receiver\u0027s signal-processing system. \n\u003C\/p\u003E\n\u003Cp\u003E\u0022Electronic analog technologies have a number of error sources and limitations when subjected to the extended temperature range that our military requires,\u0022 said Willis, a principal research engineer with GTRI\u0027s Electronic Systems Laboratory (ELSYS).  \u0022By moving the logarithmic transfer function into the digital signal-processing domain, we\u0027ve improved the stability of the circuit.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EAnalog circuits, traditionally used to detect real-world phenomena such as sound or temperature, hold a multitude of continuous values across any given range.  By contrast, digital circuits process information in discrete steps governed by the binary code that computers use.  \n\u003C\/p\u003E\n\u003Cp\u003EIn radar warning receivers, Willis explains, the continuous-scale analog implementation has been difficult to calibrate and maintain. By contrast, the digital domain needs no calibration and is more robust.\n\u003C\/p\u003E\n\u003Cp\u003EThe digital version is also far less expensive to manufacture.  \n\u003C\/p\u003E\n\u003Cp\u003E\u0022Moving the logarithmic transfer function from analog to digital probably reduces production costs of a radar warning receiver by a factor of between five and 10,\u0022 he said. \u0022The cost of the digital video portion could become nearly insignificant in comparison to the cost of the remainder of the RWR system.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EThe new digital crystal video receiver is comprised of an analog-to-digital converter and a programmable logic component.  Together, they\u0027re able to transfer most received analog signals to the more-reliable digital domain. \n\u003C\/p\u003E\n\u003Cp\u003EEarlier crystal video receiver architectures, Willis explains, detected radio-frequency (RF) signals immediately, without intermediate processing.  Such analog \u0022direct-conversion\u0022 receivers often needed multiple receivers to detect radar signals over a range of frequencies.\n\u003C\/p\u003E\n\u003Cp\u003EBy contrast, the DCVR\u0027s improvements include a capacity to readily detect RF signals through a wide range of frequencies using up-to-date broadband receiver techniques.  \n\u003C\/p\u003E\n\u003Cp\u003EScientists use the word \u0022video\u0022 to describe this technology because the receiver demodulates received radar signals into video waveforms.  The new digital crystal video receiver approach subjects those video waveforms to digital signal processing, producing a digital equivalent with a logarithmic function applied to it to make processing easier.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022Adding the word \u0022digital\u0022 to the older term \u0022crystal video receiver\u0022 emphasizes that technology advances have allowed us to overcome many limitations of the older-generation, crystal-based, direct-conversion receivers,\u0022 Willis said. \n\u003C\/p\u003E\n\u003Cp\u003EThe initial sponsored research involved a radar warning receiver used on a number of U.S. military aircraft, Willis said.  The discovery may have other military applications as well.\n\u003C\/p\u003E\n\u003Cp\u003ECommercial applications are also possible, he said. The discovery could be applied not only to radar warning receivers but to any receiver that requires a logarithmic transfer function.

It can also make aircraft interiors excessively loud.\n\u003C\/p\u003E\n\u003Cp\u003ETo address this situation, engineers at the Georgia Tech Research Institute (GTRI) are turning to innovative materials that make possible a new approach to the physics of noise reduction.  They have found that honeycomb-like structures composed of many tiny tubes or channels can reduce sound more effectively than conventional methods.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022This approach dissipates acoustic waves by essentially wearing them out,\u0022 said Jason Nadler, a GTRI research engineer.  \u0022It\u0027s a phenomenological shift, fundamentally different from traditional techniques that absorb sound using a more frequency-dependent resonance.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EThe two-year project is sponsored by EADS North America, the U.S. operating entity of EADS.\n\u003C\/p\u003E\n\u003Cp\u003EMost sound-deadening materials - such as foams or other cellular materials comprising many small cavities - exploit the fact that acoustic waves resonate through the air on various frequencies, Nadler explains.  \n\u003C\/p\u003E\n\u003Cp\u003EJust as air blowing into a bottle produces resonance at a particular tone, an acoustic wave hitting a cellular surface will resonate in certain-size cavities, thereby dissipating its energy. An automobile muffler, for example, uses a resonance-dependent technique to reduce exhaust noise.\n\u003C\/p\u003E\n\u003Cp\u003EThe drawback with these traditional noise-reduction approaches is that they only work with some frequencies - those that can find cavities or other structures in which to resonate. \n\u003C\/p\u003E\n\u003Cp\u003ENadler\u0027s research involves broadband acoustic absorption, a method of reducing sound that doesn\u0027t depend on frequencies or resonance.  In this approach, tiny parallel tubes in porous media such as metal or ceramics create a honeycomb-like structure that traps sound regardless of frequency.  Instead of resonating, sound waves plunge into the channels and dissipate through a process called viscous shear. \n\u003C\/p\u003E\n\u003Cp\u003EViscous shear involves the interaction of a solid with a gas or other fluid.   In this case, a gas - sound waves composed of compressed air - contacts a solid, the porous medium, and is weakened by the resulting friction.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022It\u0027s the equivalent of propelling a little metal sphere down a rubber hose when the sphere is just a hair bigger than the rubber hose,\u0022 Nadler explained.  \u0022Eventually the friction and the compressive stresses of contact with the tube would stop the sphere.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EThis technique, Nadler adds, is derived from classical mechanical principles governing how porous media interact with gases - such as the air through which sound waves move.  Noise abatement using micro-scale honeycomb structures represents a new application of these principles.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022You need to have the hole big enough to let the sound waves in, but you also need enough surface area inside to shear against the wave,\u0022 he said.   \u0022The result is acoustic waves don\u0027t resonate; they just dissipate.\u0022 \n\u003C\/p\u003E\n\u003Cp\u003EIn researching this approach, Nadler constructed an early prototype from off-the-shelf capillary tubes, which readily formed a low-density, honeycomb-like structure.  Further research showed that the ideal material for broadband acoustic absorption would require micron-scale diameter tubes and a much lower structural density. \n\u003C\/p\u003E\n\u003Cp\u003ECreating such low-density structures presents an interesting challenge, Nadler says.  It requires a material that\u0027s light, strong enough to enable the walls between the tubes to be very thin, and yet robust enough to function reliably amid the high-temperature, aggressive environments inside aircraft engines.  \n\u003C\/p\u003E\n\u003Cp\u003EAmong the likely candidates are superalloys, materials that employ unusual blends of metals to achieve desired qualities such as extreme strength, tolerance of high temperatures and corrosion resistance.\n\u003C\/p\u003E\n\u003Cp\u003ENadler has developed what could be the world\u0027s first superalloy micro honeycomb using a nickel-base superalloy. At around 30 percent density, the material is very light - a clear advantage for airborne applications - and also very strong and heat resistant.\n\u003C\/p\u003E\n\u003Cp\u003EHe estimates this new approach could attenuate aircraft engine noise by up to 30 percent.  Micro-honeycomb material could also provide another means to protect the aircraft in critical areas prone to impact from birds or other foreign objects by dissipating the energy of the collision.\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EResearch News \u0026amp; Publications Office\u003Cbr \/\u003E\nGeorgia Institute of Technology\u003Cbr \/\u003E\n75 Fifth Street, N.W., Suite 100\u003Cbr \/\u003E\nAtlanta, Georgia  30308  USA\u003C\/strong\u003E\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EMedia Relations Contacts\u003C\/strong\u003E: John Toon (404-894-6986); E-mail: (\u003Ca href=\u0022mailto:jtoon@gatech.edu\u0022\u003Ejtoon@gatech.edu\u003C\/a\u003E); Kirk Englehardt (404-407-7280); E-mail: (\u003Ca href=\u0022mailto:kirk.englehardt@gtri.gatech.edu\u0022\u003Ekirk.englehardt@gtri.gatech.edu\u003C\/a\u003E) or Abby Vogel (404-385-3364); E-mail: (\u003Ca href=\u0022mailto:avogel@gatech.edu\u0022\u003Eavogel@gatech.edu\u003C\/a\u003E).\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003ETechnical Contact\u003C\/strong\u003E: Jason Nadler (404-407-6104); E-mail (\u003Ca href=\u0022mailto:jason.nadler@gtri.gatech.edu\u0022\u003Ejason.nadler@gtri.gatech.edu\u003C\/a\u003E).\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EWriter\u003C\/strong\u003E: Rick Robinson\n\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":[{"value":"Innovation could help quiet military and commercial aircraft"}],"field_summary":[{"value":"Researchers at the Georgia Tech Research Institute (GTRI) are developing innovative honeycomb structures that could make possible a new approach to noise reduction in aircraft.","format":"limited_html"}],"field_summary_sentence":[{"value":"A new approach to sound control could help quiet jet aircraft"}],"uid":"27303","created_gmt":"2008-09-29 00:00:00","changed_gmt":"2016-10-08 03:03:19","author":"John Toon","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2008-09-29T00:00:00-04:00","iso_date":"2008-09-29T00:00:00-04:00","tz":"America\/New_York"},"extras":[],"hg_media":{"70932":{"id":"70932","type":"image","title":"Jason Nadler","body":null,"created":"1449177328","gmt_created":"2015-12-03 21:15:28","changed":"1475894625","gmt_changed":"2016-10-08 02:43:45"},"70933":{"id":"70933","type":"image","title":"Jason Nadler","body":null,"created":"1449177328","gmt_created":"2015-12-03 21:15:28","changed":"1475894625","gmt_changed":"2016-10-08 02:43:45"},"70934":{"id":"70934","type":"image","title":"Noise reduction material","body":null,"created":"1449177328","gmt_created":"2015-12-03 21:15:28","changed":"1475894625","gmt_changed":"2016-10-08 02:43:45"}},"media_ids":["70932","70933","70934"],"related_links":[{"url":"http:\/\/www.gtri.gatech.edu\/","title":"Georgia Tech Research Institute"}],"groups":[{"id":"1188","name":"Research Horizons"}],"categories":[{"id":"136","name":"Aerospace"},{"id":"145","name":"Engineering"},{"id":"147","name":"Military Technology"},{"id":"135","name":"Research"}],"keywords":[{"id":"1833","name":"aircraft"},{"id":"7185","name":"honeycomb"},{"id":"1692","name":"materials"},{"id":"1522","name":"noise"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EJohn Toon\u003C\/strong\u003E\u003Cbr \/\u003EResearch News \u0026amp; Publications Office\u003Cbr \/\u003E\u003Ca href=\u0022http:\/\/www.gatech.edu\/contact\/index.html?id=jt7\u0022\u003EContact John Toon\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-6986\u003C\/strong\u003E","format":"limited_html"}],"email":["jtoon@gatech.edu"],"slides":[],"orientation":[],"userdata":""}},"71098":{"#nid":"71098","#data":{"type":"news","title":"GTRI Wins Contract to Support Test \u0026 Evaluation of Unmanned Systems","body":[{"value":"\u003Cp\u003EThe Georgia Tech Research Institute (GTRI) has won a contract to support development of a roadmap designed to improve the testing and evaluation of unmanned and autonomous systems for the U.S. Office of the Secretary of Defense (OSD).\n\u003C\/p\u003E\n\u003Cp\u003E\u0022The field of unmanned and autonomous systems is evolving rapidly, and new techniques are needed to effectively test and evaluate the capabilities that are being inserted into these systems.

McCrory, a GTRI senior research engineer.  Some 7,500 of these ground communications radios - known as AN\/GRT-21 and AN\/GRT-22 transmitters and AN\/GRR-23 and AN\/GRR-24 receivers - are still in service. When they break down, they often require parts that are no longer available.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022This system has been in the field almost 40 years now,\u0022 said McCrory, who is project director.  \u0022Many parts now unavailable were originally manufactured by hand, and would be very expensive to reproduce today just because of the manual labor involved.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EAmong other things, GTRI engineers must find ways to replace numerous semiconductor components, such as transistors and diodes that are no longer manufactured.  In some cases the original makers are no longer in business; in other cases the products are so old that no replacements are available.\n\u003C\/p\u003E\n\u003Cp\u003EInstead of trying to reproduce the original technology, GTRI engineers are designing replacement units that use only modern off-the-shelf parts.  The aim is to give the customer a replacement module that is plug-compatible with the original unit and does the same job.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022We throw away the original design, and we make a unit with the same size and the same function,\u0022 McCrory said. \u0022If the old unit had a certain meter reading to show a certain condition, the new one should work identically.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EThe current $4.05 million contract covers redesign of five major assemblies within the GRT\/GRR, a complex system of receivers and transmitters that operates in the VHF and UHF radio-frequency bands.  The five assemblies include a dual-band power amplifier unit, an intermediate-frequency (IF) amplifier, a mixer-multiplier, a power supply unit and a synthesizer.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022This work provides both a technical challenge and a demonstration of GTRI\u0027s commitment to deliver on fast-reaction contracts,\u0022 McCrory said. \u0022Within 12 months, GTRI will produce five complete new designs including all data necessary for the government to obtain competitive bids from manufacturers, engineer prototypes, obtain the initial devices from an outside vendor and update user and operator manuals.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EHe said that GTRI\u0027s changes to the dual-band power amplifier will retain that assembly\u0027s unusual capacity to broadcast a 10-watt radio signal in either the VHF or UHF bands.  \n\u003C\/p\u003E\n\u003Cp\u003EIn addition, the new design will re-engineer the mixer multiplier - a unit that converts received frequencies to a range that can be processed by the receiver - and also modify the IF (intermediate frequency) amplifier in the receiver, which amplifies the received radio signals. And a new power supply will increase reliability.\n\u003C\/p\u003E\n\u003Cp\u003EIn replacing the current radio\u0027s original analog components, GTRI engineers are crafting a system that is still all-analog but uses new off-the-shelf technology that is widely available. This approach allows the Air Force to ask for competitive bids from numerous manufacturers rather than relying on a sole source.\n\u003C\/p\u003E\n\u003Cp\u003EThe savings can be substantial, McCrory said. He cites a competing approach that would have cost the government about $500,000 for drawings of one obsolete transistor in the GRT system, and then another $500,000 for the first transistor reproduced from those drawings.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022Our approach will result in major savings for the military versus trying to remanufacture the original components,\u0022 he said.\n\u003C\/p\u003E\n\u003Cp\u003EGTRI\u0027s role in maintaining the GRT\/GRR radios has evolved over several years. In 1999 the Warner Robins Air Logistics Center at Georgia\u0027s Robins Air Force Base took over engineering responsibility for the radios, and in 2005 GTRI engineers were asked to produce GRT\/GRR technical documentation.\n\u003C\/p\u003E\n\u003Cp\u003ESubsequently, GTRI created a support roadmap for sustaining the units until they are retired, and the analysis showed that major radio components needed to be replaced to meet this goal. \n\u003C\/p\u003E\n\u003Cp\u003EMcCrory adds that his team has made extensive use of GTRI\u0027s SUSTAIN software in helping to identify modules requiring redesign and to justify funding requests. SUSTAIN is a multi-part management tool that helps guide maintenance\/sustainment decisions on older military systems. \n\u003C\/p\u003E\n\u003Cp\u003EEventually, McCrory explains, all Department of Defense radios are due to be replaced by a reprogrammable, software-based technology known as the Joint Tactical Radio System (JTRS).  Though the first JTRS systems could begin replacing high-priority radios as early as 2011, ground radios like the GRT\/GRR systems are scheduled for replacement much later - probably not until 2020 to 2025.  That means GRT\/GRR radios could require maintenance for another 18 years.  \n\u003C\/p\u003E\n\u003Cp\u003EGTRI expects its redesign to help ease the Air Force\u0027s parts inventory and logistics tasks for these radios.

Sponsored by the U.S. Defense Advanced Research Projects Agency Defense Sciences Office (DARPA-DSO), the 18-month project seeks to demonstrate the use of propellant-less cathodes with Hall effect thrusters.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022About 10 percent of the propellant carried into space on satellites that use an electric propulsion system is essentially wasted in the hollow cathode that is part of the system,\u0022 said Mitchell Walker, an assistant professor in Georgia Tech\u0027s School of Aerospace Engineering and the project\u0027s principal investigator.  \u0022Using field emission rather than a hollow cathode, we are able to pull electrons from cathode arrays made from carbon nanotubes without wasting propellant.  That will extend the life of the vehicle by more efficiently using the limited on-board propellant for its intended purpose of propulsion.\u0022\n\u003C\/p\u003E\n\u003Cp\u003ETo maintain their positions in space or to reorient themselves, satellites must use small thrusters that are either chemically or electrically powered.  Electrically-powered thrusters use electrons to ionize an inert gas such as xenon.  The resulting ions are then ejected from the device to generate thrust.\n\u003C\/p\u003E\n\u003Cp\u003EIn existing Hall effect thrusters, a single high-temperature cathode generates the electrons.  A portion of the propellant -- typically about 10 percent of the limited supply carried by the satellite -- is used as a working fluid in the traditional hollow cathode.  The DARPA-funded research would replace the hollow cathode with an array of field-effect cathodes fabricated from bundles of multi-walled carbon nanotubes.  Powered by on-board batteries and photovoltaic systems on the satellite, the arrays would operate at low power to produce electrons without consuming propellant.\n\u003C\/p\u003E\n\u003Cp\u003EWalker and collaborators at the Georgia Tech Research Institute (GTRI) have already demonstrated field-effect cathodes based on carbon nanotubes.  This work was presented at the 2009 AIAA Joint Propulsion Conference held in Denver, Colo.  The additional funding will support improvements in the devices, known as carbon nanotube cold cathodes, and lead to space testing as early as 2015.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022This work depends on our ability to grow aligned carbon nanotubes precisely where we want them to be and to exacting dimensions,\u0022 said Jud Ready, a GTRI senior research engineer and Walker\u0027s collaborator on the project.  \u0022This project leverages our ability to grow well-aligned arrays of nanotubes and to coat them to enhance their field emission performance.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EIn addition to reducing propellant consumption, use of carbon nanotube cathode arrays could improve reliability by replacing the single cathode now used in the thrusters. \n\u003C\/p\u003E\n\u003Cp\u003E\u0022Existing cathodes are sensitive to contamination, damaged by the ionized exhaust of the thruster, and have limited life due to their high-temperature operation,\u0022 Ready noted. \u0022The carbon nanotube cathode arrays would provide a distributed cathode around the Hall effect thruster so that if one of them is damaged, we will have redundancy.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EBefore the carbon nanotube cathodes developed by Georgia Tech can be used on satellites, however, their lifetime will have to be increased to match that of a satellite thruster, which is typically 2,000 hours or more.  The devices will also have to withstand the mechanical stresses of space launches, turn on and off rapidly, operate consistently and survive the aggressive space environment.\n\u003C\/p\u003E\n\u003Cp\u003EPart of the effort will focus on special coating materials used to protect the carbon nanotubes from the space environment.  For that part of the project, Walker and Ready are collaborating with Lisa Pfefferle in the Department of Chemical Engineering at Yale University.  \n\u003C\/p\u003E\n\u003Cp\u003EThe researchers are testing their cathodes with the same Busek Hall effect thruster that flew on the U.S. Air Force\u0027s TacSat-2 satellite.  In addition, the cathodes will be operated with Hall effect thrusters developed by Pratt \u0026amp; Whitney and donated to Georgia Tech.  The researchers are also collaborating with L-3 ETI on the electrical power system and with American Pacific In-Space Propulsion on flight qualification of the hardware.\n\u003C\/p\u003E\n\u003Cp\u003EThe ability to control individual cathodes on the array could provide a new capability to vector the thrust, potentially replacing the mechanical gimbals now used.\n\u003C\/p\u003E\n\u003Cp\u003EThe use of carbon nanotubes to generate electrons through the field-effect process was reported in 1995 by a research team headed by Walt de Heer, a professor in Georgia Tech\u0027s School of Physics.

Satellites using the Georgia Tech engine to blast off can carry more payload thanks to the mass freed up by the smaller amount of fuel needed for the trip into orbit. Or, if engineers wanted to use the reduced fuel load another way, the satellite could be launched more cheaply by using a smaller launch vehicle.\n\u003C\/p\u003E\n\u003Cp\u003EThe fuel-efficiency improvements could also give satellites expanded capabilities, such as more maneuverability once in orbit or the ability to serve as a refueling or towing vehicle.\n\u003C\/p\u003E\n\u003Cp\u003EThe Georgia Tech project, lead by Dr. Mitchell Walker, an assistant professor in the Daniel Guggenheim School of Aerospace Engineering, was funded by a grant from the U.S. Air Force.

A traditional chemical rocket engine (attached to a satellite ready for launch) runs at maximum exhaust velocity until it reaches orbit, i.e. first gear.\u003C\/p\u003E\n\u003Cp\u003EThe new Georgia Tech engine allows ground control units to adjust the engine\u0027s operating gear based on the immediate propulsive need of the satellite. The engine operates in first gear to maximize acceleration during orbit transfers and then shifts to fifth gear once in the desired orbit. This allows the engine to burn at full capacity only during key moments and conserve fuel.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022You can really tailor the exhaust velocity to what you need from the ground,\u0022 Walker said.\n\u003C\/p\u003E\n\u003Cp\u003EThe Georgia Tech engine operates with an efficient ion propulsion system. Xenon (a noble gas) atoms are injected into the discharge chamber. The atoms are ionized, (electrons are stripped from their outer shell), which forms xenon ions.

Ground control units can then exercise this control remotely to conserve fuel.\n\u003C\/p\u003E\n\u003Cp\u003EThe satellite engine is almost ready for military applications, but may be several years away from commercial use, Walker added.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":[{"value":"Engine lets satellites take more hardware into orbit, reposition more easily"}],"field_summary":[{"value":"Georgia Tech researchers have a created a new satellite technology that allows satellites to blast off with less fuel, opening the door for deep space missions, lower launch costs and more hardware on board.","format":"limited_html"}],"field_summary_sentence":[{"value":"Savings allow deep space missions, cheaper launch"}],"uid":"27281","created_gmt":"2007-02-22 01:00:00","changed_gmt":"2016-10-08 03:01:37","author":"Lisa Grovenstein","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2007-02-22T00:00:00-05:00","iso_date":"2007-02-22T00:00:00-05:00","tz":"America\/New_York"},"extras":[],"hg_media":{"72319":{"id":"72319","type":"image","title":"Georgia Tech engine","body":null,"created":"1449177454","gmt_created":"2015-12-03 21:17:34","changed":"1475894656","gmt_changed":"2016-10-08 02:44:16"},"72320":{"id":"72320","type":"image","title":"Mitchell Walker","body":null,"created":"1449177454","gmt_created":"2015-12-03 21:17:34","changed":"1475894656","gmt_changed":"2016-10-08 02:44:16"}},"media_ids":["72319","72320"],"related_links":[{"url":"http:\/\/www.ae.gatech.edu\/people\/mwalker\/","title":"Dr. Mitchell Walker"},{"url":"http:\/\/www.ae.gatech.edu\/","title":"Daniel Guggenheim School of Aerospace Engineering"}],"groups":[{"id":"1214","name":"News Room"}],"categories":[{"id":"136","name":"Aerospace"},{"id":"145","name":"Engineering"},{"id":"147","name":"Military Technology"},{"id":"135","name":"Research"}],"keywords":[{"id":"1325","name":"aerospace"},{"id":"2479","name":"deep space mission"},{"id":"516","name":"engineering"},{"id":"246","name":"Georgia Institute of Technology"},{"id":"2474","name":"Mitchell Walker"},{"id":"169609","name":"satellite"},{"id":"169608","name":"satellites"},{"id":"167589","name":"School of Aerospace Engineering"},{"id":"2478","name":"U.S. Air Force"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003ELisa Grovenstein\u003C\/strong\u003E\u003Cbr \/\u003ECommunications \u0026amp; Marketing\u003Cbr \/\u003E\u003Ca href=\u0022http:\/\/www.gatech.edu\/contact\/index.html?id=lgrovenste3\u0022\u003EContact Lisa Grovenstein\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-8835\u003C\/strong\u003E","format":"limited_html"}],"email":["lisa.grovenstein@comm.gatech.edu"],"slides":[],"orientation":[],"userdata":""}}}
