Spacecraft Charging - Hazard Causes, Hazard Effects, Hazard Controls
Explore spacecraft charging hazards, their causes, effects, and control measures in this comprehensive seminar presented by Steven Koontz, ISS System Manager for Space Environments. Delve into the interdisciplinary nature of spacecraft charging analysis, combining electrostatics, plasma physics, ionizing radiation, and materials science. Examine how interactions with space plasmas, energetic charged particles, solar UV photons, and spacecraft systems lead to charge accumulation. Learn about the specific charging environments encountered by the International Space Station (ISS) in low Earth orbit and compare ISS charging measurements with numerical modeling. Investigate the unique challenges of spacecraft charging in Earth's magnetosphere and cis-Lunar space, and assess the applicability of ISS charging management techniques to future human spaceflight missions beyond LEO. Gain insights into various spacecraft charging environments, including the LEO ionosphere, magnetosphere, and geosynchronous orbit, as well as internal charging processes. Read more
