抄録

Small particles of less than 0.5 mm diameter collide with spacecraft solar panels, which work as an electrical power supply. Sustained arc discharging does not occur during such impacts, although trigger discharges are generated during several hundreds of milliseconds. The electrical performance of the solar panels is degraded slightly, but not enough to affect satellite systems.
