This talk is about ground testing of spacecraft to determine immunity to the electrostatic discharges (ESDs) in certain Earth orbits. The particular spacecraft used as an example is the TOPEX/Poseidon spacecraft, an Earth orbiter with a 1334 km, 62 degree orbit. The talk is based on my recent experience with that spacecraft, but is an example of a generally good program. The program and this talk consist of the following elements: a discussion of the environment, showing the specific hazard areas on the spacecraft to illustrate the space charging and ESD process; spacecraft design features related to the environmental threat; the test device used for TOPEX/Poseidon; the test itself, including logistic and actions to avoid inadvertent damage to the spacecraft; and conclusions and lessons learned.
