About the talk

Located 1.5 million kilometers from Earth and operating over temperatures ranging from 360 Kelvin down to 7 Kelvin, the James Webb Space Telescope presents unique engineering challenges as it seeks to expand our understanding of the origins of the universe and search for habitable exo-planets.  Focusing on the JWST Mid-Infrared Imager Cryocooler as a case study in the trades necessary amongst engineering disciplines while taking into account larger mission and programmatic considerations, this talk will show how the design and evolution of one small bracket can tell the story of the most complex space telescope ever built.

About the Speaker

An employee of Northrop Grumman Aerospace Systems since 2005, Kelley Ristau is currently a Senior Mechanical Test Engineer supporting the James Webb Space Telescope (JWST).  Prior to her assignment on JWST, Kelley has worked in a range of roles at NGAS, including Manufacturing Engineering, Business Development, Mechanical Design, and Materials Engineering and Research.  Kelley holds a B.S. Aerospace Engineering from the University of California, San Diego, and an M.S. Engineering from the University of California, Los Angeles, where her work focused on the utility of additive manufacturing in the fabrication of lightweight mirror segments for future space telescopes.
