Abstract
Modeling of space plasma environment-induced anomalies requires knowledge of:
- Environment and impinging fluxes during spacecraft orbits, which are mission specific and can be incorporated through environmental models and databases.
- Satellite geometry and orientation in the space environment, accomplished through such charging codes as NASCAP-2K, SPENVIS, or MUSCAT.
- Materials used in spacecraft construction, from the specific spacecraft design.
- Relevant materials properties characterizing the interaction of the materials with the environment and how these properties may change with exposure to the space environment.
A reliable, comprehensive database of spacecraft materials and the characterization of those materials is being created in the form of a materials charging database. This is being done to provide an improved, more informed modeling tool for environment-induced spacecraft charging.
