COMMENTS:

Dr. Garrett has a wide variety of experience and over 150 publications in the space environment and its effects with specific emphasis in the areas of atmospheric physics, low earth ionosphere, radiation, micrometeoroids, space plasma environments, and effects on materials and systems in space.  While on active duty in the Air Force (1974-1980), he served as Project Scientist for the highly successful SCATHA program which characterized the geosynchronous spacecraft charging environment.  For his work on this program in developing a predictive space environment model of the geosynchronous plasma, he was awarded the Harold Brown Award (top AF scientist), AF Systems Command Officer of the Year, and the AF R&D Award.  At JPL, he was responsible for defining the space environment and its effects on reliability for many NASA missions ranging from Galileo and Cassini to Juno and Europa Orbiter.  He has published four textbooks on the space environment and its impact on spacecraft design and reliability and served as an Associate Editor of the Journal of Spacecraft and Rockets. In 1992, he was selected by the DoD and JPL for a temporary assignment at the Pentagon as part of the Ballistic Missile Defense Organization where he acted as the Deputy Program Manager for the DoD/NASA Clementine Lunar Mission and Program Manager for the Clementine InterStage Adapter Satellite (ISAS).  For contributions to this mission in measuring the Earth and trans-Lunar space environments and their effects on the reliability of advanced space systems, he was awarded NASA’s Medal for Exceptional Engineering Achievement.  He returned to JPL in 1994 where he served as the Chief Technologist for the Office of Safety and Mission Success until 2011.  Dr. Garrett is an international consultant on the terrestrial and interplanetary space environments and spacecraft reliability having worked for INTELSAT, L’Garde, Loral, NASDA, CNES, and other organizations.  Until 2002, he also served as a Colonel in the USAF Reserves, assigned as the Senior Reserve Officer for the AF Space and Missile Center for which he received the AF’s Legion of Merit Medal in 2002.  In 2006, Dr. Garrett received NASA’s Exceptional Service Medal for “his achievements in advancing the understanding of space environments and effects.”  Dr. Garrett co-authored the primary NASA standard on spacecraft surface and internal charging for Earth missions and hosted the International Spacecraft Charging Technology Conference in Pasadena, CA in 2014.  Dr. Garrett edited the conference proceedings which appeared as a special issue of the IEEE Journal Transactions on Plasma Science.  He has developed models of the Saturnian, Uranian, Neptunian, and Jovian radiation belts and the plasma/charging environment at Jupiter (the latter two for the Europa mission) and consulting on other JPL missions.  In 2019 he was selected as a Fellow for the American Institute of Aeronautics and Astronautics.  Recently he received the AIAA Van Allen Space Environments Award.
