High-Level Spacecraft Charging at Geosynchronous Altitudes: A Statistical Study.

The onset of spacecraft charging at geosynchronous altitudes occurs at a critical value of the space plasma electron temperature for a given spacecraft surface. We review the theoretical formulation and computational results and compare the results with the Los Alamos National Laboratory spacecraft charging observations. The observations show that the onset of charging occurs at a critical temperature in almost every charging event, no matter which satellite, which year, and which month. It is also observed that the critical temperature values remain the same no matter in eclipse or in sunlight.
