About
Dr. G. Courtney is a pioneering experimental space physicist whose research focuses on spacecraft–plasma interactions, particularly the complex electrical phenomena occurring in plasma wakes in low Earth orbit. Her most significant contribution is the Charging Hazards and Wake Studies (CHAWS) flight experiments, conducted aboard Space Shuttle missions STS-60 and STS-69. These groundbreaking experiments directly measured high-voltage (0–5 kV) interactions between a negatively biased probe and the plasma wake behind a spacecraft, providing the first definitive data on how spacecraft charging and arcing hazards arise in such environments. Her 1997 paper summarizing these results has garnered 29 citations, serving as a foundational reference for spacecraft charging models and hazard mitigation strategies. Dr. Courtney’s work is notable for its direct relevance to the design and safety of high-voltage power systems on satellites and space stations, influencing both NASA’s operational guidelines and subsequent experimental missions. Her research remains essential reading for engineers and scientists developing next-generation spacecraft that must operate reliably in the dynamic, charged-particle environment of space.
