Dr. Robert F. Pfaff, Jr. is a Space Scientist in the Space Weather Laboratory in the Heliophysics Division of the NASA/Goddard Space Flight Center. Since his arrival at NASA in 1985, he has been the leader of the Electric Field Investigation Team at Goddard, providing state-of-the-art in situ experiments for use on both satellites and sounding rockets. Dr. Pfaff’s electric field team is the sole such laboratory in all of NASA.
Dr. Pfaff is the Principal Investigator of the Vector Electric Field Investigation (VEFI) on the Air Force C/NOFS satellite that is providing the most accurate, vector DC electric field measurements ever gathered in the Earth’s ionosphere.
Within NASA’s sounding rocket program, Dr. Pfaff has provided electric field, magnetic field, and plasma density measurements for 47 rocket missions to date. All of the hardware has been delivered on time and on budget and all experiments have performed at high levels of accuracy and sensitivity.
Dr. Pfaff has served as Project Scientist for the FAST satellite since 1990, Project Scientist for the Sounding Rocket program since 1994, and Project Scientist for the NASA-funded CINDI “Mission of Opportunity” since 2003. In every case, his efforts have significantly advanced these projects and have helped ensure their scientific success.
Dr. Pfaff has been a frequent invited speaker at international scientific symposia, and has co-convened an AGU Chapman Conference on “Space Plasma Measurement Techniques”. He has published over 150 papers in the refereed literature with over 3000 citations and an H-index of 29. He has written a book chapter on in situ measurement techniques (1996) as well as a major review article on the ionosphere for Space Science Reviews (2012).
Dr. Pfaff has received the following awards and medals since coming to NASA:
-- Robert H. Goddard Award for Exceptional Achievement in Science in 2008.
-- NASA Exceptional Service Medal in 2007.
-- NASA Exceptional Achievement Medal in 1996.
