Improved Satellite Robustness Through Application of Erosion Resistance and High Emissivity Coatings
Session
Technical Poster Session 4
Location
Utah State University, Logan, UT
Abstract
- Spacecraft can experience charging throughout operation due to high flux of incident electrons (ex. during geomagnetic substorm). As a result, different materials/components may experience a range of potentials which may lead to plasma-induced arcs, damaging spacecraft components.
- 54% of spacecraft failures are due to enhancement of radiation belt particles and magnetospheric plasma that cause charging/discharing
- Current space charge mitigation technologies:
- Metallic coatings
- System chassis ground leads to as many surfaces as possible
- Not effective in severe sub-storm conditions and do not enable local application of coating
