Interactions between spacecraft and their environments are discussed using the SSF and the SP-100 power system. It is recommended that discontinuous structure potentials of more than 100 V on a spacecraft must be connected with an insulating material of sufficient thickness to stand off the potential difference. Particular attention must be paid to conductors with a plasma arcing threshold higher than the conductor potential relative to the surrounding plasma. To avoid arcing, spacecraft surfaces should avoid exposed conductors, or at least exposed conductor-insulator junctions for LEO missions. To avoid differential charging, fully conductive surfaces should be used every where for GEO missions.
