Aerospace Physics Consultant 



Born February 15, 1948, in San Francisco, California, Henry Garrett grew up in Roswell, New Mexico.  He subsequently attended undergraduate and graduate school at Rice University, Houston, Texas, where he obtained his undergraduate degree in physics (magna cum laude, Phi Beta Kappa, Woodrow Wilson Fellow, NSF Fellow) in 1970 and his doctorate in Space Physics and Astronomy in 1973.  His thesis dealt with modeling of the Earth’s magnetospheric plasma and its interactions with the Solar Wind.  After serving briefly on the Rice faculty, Dr. Garrett was commissioned into the United States Air Force and assigned to the Air Force Geophysics Laboratory (originally the Air Force Cambridge Research Laboratories), Bedford, Massachusetts, in atmospheric physics.  In 1976, Capt. Garrett was appointed as the AFGL Project Scientist for the Air Force/NASA SCATHA (Spacecraft Charging at High Altitudes) satellite program.  His work on this program led to his selection for Air Force Systems Command Officer of the Year, Air Force Outstanding Scientist (the Harold Brown Award), and the Air Force R&D Award.  Dr. Garrett was a full Colonel in the Air Force Reserves.  In 1997 he completed an assignment as the Senior Reservist for the Air Force Research Laboratory’s Edwards AFB operating location (AF Rocket Propulsion Laboratory).  From 1999 to 2002, he served as the Senior Reserve Officer for the Air Force Space and Missile Center (SMC) and the Space Based InfraRed Sensor (SBIRS) Program Office where he was the senior technical advisor and commanded the SMC Reserve unit.  Upon his retirement in October of 2002, he received the AF’s Legion of Merit Medal.

On completion of active duty in June 1980, Dr. Garrett joined the California Institute of Technology’s Jet Propulsion Laboratory where he was Lead Technologist for the Office of Engineering and Review from 1984 to 1992.  In this capacity, he served as the chief technical representative for over 500 people in the fields of space environments, spacecraft reliability, and software reliability.  Dr. Garrett was responsible for creation of the joint Air Force/NASA Interactions Measurements Payload for Shuttle (IMPS) project and served for 5 years as the project scientist coordinating the activities of approximately 20 research teams that were developing instruments for the mission.  He has been the Group Supervisor of the Radiation and Space Environments Group (directing over 1 million dollars a year in resources) and served as a consultant for numerous NASA missions.  He was responsible for determining the effects of meteoroid, radiation, and spacecraft charging environments on the Galileo mission as part of the Galileo Earth Avoidance Study for Nuclear Safety.  He has been used as an environmental interactions consultant on such diverse missions as TDRSS, Voyager, Magellan, GOES, and AXAF.  He has served for approximately 10 years as a private consultant for INTELSAT.  For 4 years, he supported the NASA Space Station as a task manager of a study on the environmental effects of the Space Station and its systems.  He also was the Reliability and Quality Assurance focal point for the optical design of the HARP (Hubble Space Telescope Aberration Recovery Project) and reported directly to the NASA Associate Administrator for Quality Assurance.  He supported the CRAF/CASSINI project by modeling comet dust effects on spacecraft surfaces, meteoroid impacts, and spacecraft charging.  He is currently the chief consultant on the radiation environment for JPL missions to Jupiter.

Between 1992-94, Dr. Garrett was an IPA (detailee) with the Department of Defense’s Ballistic Missile Defense Organization (formerly the Strategic Defense Initiative Organization).  In that capacity, he served as special assistant to the Innovative Science and Technology Office (Dr. D. Duston, director) where he worked for Col. P. Rustan on the Clementine, POAM, and SPEAR programs. On the Clementine Program, Dr. Garrett served initially as the Program Chief Scientist.  As the program evolved he was assigned responsibilities as the Program Manager for the Clementine ISAS (a sub-satellite left behind in Earth orbit to test Clementine technologies in the harsh Earth environment and to monitor space debris and meteoroids) and as head of the Clementine Engineering Working Group (charged with analyzing the engineering findings of the Clementine Program).  Following the outstanding success of the mission, he was awarded NASA’s Medal for Exceptional Engineering Achievement by Dr. Goldin, NASA Administrator.  Dr. Garrett returned to JPL in 1994 and is currently the Office of Safety and Mission Success’ Lead Technologist.  He has served as the Mission Assurance Lead for the X2000 Program and the Pre-Phase A JIMO mission design and is developing new models of the jovian and saturnian radiation environments, interplanetary meteoroids, and the interstellar environment for missions ranging from the Interstellar Probe and Solar Sail to Europa and Juno.  In 2006, Dr. Garrett received NASA’s Exceptional Service Medal.

Dr. Garrett is an internationally recognized expert and frequent lecturer on radiation effects, spacecraft environments, and interactions.  His book on the subject, entitled Space Systems and Their Interactions with Earth’s Space Environment, appeared as Volume 71 in the AIAA Aeronautics and Astronautics series.  With Prof. D. Hastings of MIT, he completed his second, Spacecraft-Environment Interactions, for Cambridge Press in October 1996.  In 1999, he prepared the official AIAA guideline on the Earth’s radiation environment: “Guide to Modeling Earth’s Trapped Radiation Environment”.  His reviews of the spacecraft charging, the near-earth space plasma and radiation environment, and spacecraft glow, have frequently appeared in the Reviews of Geophysics and Space Physics and the Journal of Spacecraft and Rockets.  In 1986, Dr. Garrett was invited by the French space agency to teach courses at Toulouse on space plasmas and spacecraft charging.  In 1987, he was invited by NATO to again serve as a consultant to the French space agency (ONERA), presenting a week long series of lectures to ONERA and ESA on spacecraft design in Paris.  During the same period, he delivered an invited lecture on space plasma environments at the International Union of Radio Science’s annual meeting in Tel Aviv, flown there at the Union’s expense.  Twice he has been flown by NASDA (the Japanese space agency) and other international organizations to Japan to present invited talks on space radiation environments for international conferences on space interactions with microelectronics.  He is a lecturer/teacher for Launchspace, Inc. and JPL on spacecraft interactions.  To date, Dr. Garrett has published over 100 referred scientific articles, in numerous professional journals on a wide range of space physics topics.  Dr. Garrett has been an Associate Editor of the AIAA Journal of Spacecraft and Rockets.  He is an Associate Fellow of the AIAA and a member of the American Geophysical Union, the Astronomical Society of America, the American Institute of Physics, and the International Association of Geomagnetism and Aeronomy.  He was an officer of the latter organization for over 8 years during which he organized and chaired sessions at 4 international conferences.  Dr. Garrett has been active in the community as a leader/founder of a Boy Scout Explorer Post and as an officer of his church.
