Abstract : A study was conducted to provide an assessment of the capability of using existing databases to determine the seriousness of environmental effects on spacecraft. The conclusion of this study is that at least 20% of all anomalies, including some satellite failures, have been caused by environmental effects. However, existing databases are inadequate to determine the complete extent of environmental effects on satellites. The most serious problem with existing databases is the lack of anomaly time and spacecraft position information. These are essential to relating anomalies to the space environment.
