Abstract:

The charging effects of a conducting and a conductingdielectric model spacecraft in the impact induced plasma environment are contrasted. The results of dynamic model calculations indicate larger charging times and higher positive spacecraft potentials for a conductingdielectric spacecraft. The potential and particle distributions around the spacecraft differ quantitatively and qualitatively in both cases.
