What is it about?
Surface charging at geosynchronous altitude refers to the accumulation of electric charge on the surface of satellites and spacecraft when they orbit at the geosynchronous altitude around Earth. This phenomenon poses a significant concern for space missions because extreme surface charging events can lead to malfunctions and anomalies in spacecraft systems. During substorms, the plasma environment around Earth's geosynchronous orbit exhibits complex behavior, which is better modeled as two-temperature non-Maxwellian plasma. To understand and mitigate the effects of surface charging, researchers employ advanced techniques such as the two-temperature q-non-extensive distribution function.
