Who's Who at NASA

Dr. Jim Green, Director, Planetary Science Division, NASA Headquarters, Washington, DC

Dr. Jim Green began his NASA career in 1980 at Marshall Space Flight Center’s Magnetospheric Physics Branch where he developed and managed the Space Physics Analysis Network (SPAN), NASA’s precursor to the Internet. From 1985 to 1992 he served as Head of the National Space Science Data Center at the Goddard Space Flight Center, followed by a 13-year stint as Chief of the Space Science Data Operations Office. In 2005 he was named Chief of the Science Proposal Support Office, where he served until August 2006 when he was appointed Director of NASA’s Planetary Science Division.

Dr. Robert Youngquist, Lead Scientist, Applied Physics Laboratory, Kennedy Space Center, FL

After a brief career teaching at University College London in the U.K., Dr. Robert Youngquist returned to the U.S. and went to work as a contractor at the Kennedy Space Center (KSC) in 1988. He established KSC’s Optical Instrumentation Laboratory, which developed ground support equipment for the space shuttle program. In 1999 he accepted a full-time position with NASA and established KSC’s Applied Physics Laboratory, which he still leads today. In 2009 Dr. Youngquist received KSC’s inaugural Engineer/Scientist of the Year Award for his scientific innovations, leadership, and mentoring of students who are pursuing advanced degrees.

Terry Hill, Engineering Project Manager, Constellation Spacesuit System, Johnson Space Center, Houston, TX

While pursuing a master’s degree in aerospace guidance, navigation, and control theory at UT Austin, Terry Hill got an opportunity to work at NASA JSC as a primary investigator on a project his educational advisor was conducting. This led to him being accepted into the Aeroscience and Flight Mechanics division as a graduate co-op in 1998, and an offer of full-time employment in 1999. Since then, Hill has worked on a variety of projects including the Orbital Space Plane, the STS-114 Return to Flight mission, the navigation software for space station assembly missions, and the X-38 Crew Return Vehicle. He is currently developing NASA’s next-generation spacesuit as the Engineering Project Manager for the Constellation Spacesuit System.

Michael Ewert, Deputy Project Manager, Exploration Life Support (ELS) Project, Johnson Space Center, Houston, TX

In 2001, NASA engineer Michael Ewert developed and patented a unique solar-powered vapor-compression refrigeration system that operates without batteries or external power of any kind. The system, which is powered by a photovoltaic panel and custom-designed electronic controls, could be used not only for long-duration space missions but also to build more environmentally friendly refrigeration systems here on Earth. Currently, Ewert is the Deputy Project Manager for NASA’s Exploration Life Support Project, which is developing new technologies needed to sustain human life on long-duration space exploration missions.

Dr. William Ko, Aerospace Engineer, Engineering Directorate, Aerostructures Branch, Dryden Flight Research Center

Dr. William Ko joined NASA’s Dryden Flight Research Center in 1977 after receiving a PhD in aeronautics from California Institute of Technology and conducting research at Southwest Research Institute in San Antonio, Texas. An accomplished scientist and inventor, he is credited with developing a number of mathematical theories critical to advancing the state-of-the-art in aerospace structural mechanics including the Blatz-Ko Constitutive Law for hyper-elastic materials, the Ko Flight Structure Aging Theory for fatigue life predictions, and the Ko Displacement Theory for structural shape predictions. The Ko Displacement Theory is currently being used at NASA Dryden to develop sophisticated fiber optic shape sensing technology that could one day give aircraft wings the ability to alter their shape in flight.
