High-energy electron irradiation of insulators in vacuum causes both internal regions and surfaces of insulators to achieve high (negative) static voltage relative to nearby ground. Occasional spontaneous discharges inject pulses of partially ionized gas composed of the insulating material and surface gas-adatoms into the adjacent vacuum.

Missions to Europa and other moons of Jupiter will experience the most severe radiation environment in the Solar System outside the Sun.
Spacecraft electric insulators are sources of spacecraft anomalies especially as the spacecraft experiences the radiation belts around Earth.
The NASA Orbiting Technology Test-bed Inititative (OTTI) will evaluate the effects of real-time space environments on advanced spacecraft technologies.
A number of performance-limiting spacecraft problems will be qualitatively discussed: Spacecraft Charging, Deep Dielectric Charging, Solar Cell Arcing, Antenna Sparking, High Voltage Power Shorts, Radiation-induced Defects in Semiconductors, and Degradation of Electronic Devices.
