Spacecraft anomalies on the CRRES satellite correlated with the environment and insulator samples

The CRRES satellite has been extensively surveyed for the occurrence of onboard anomalies. CRRES system and instrument responses which were not programmed or commanded are classified as anomalies. The history of anomalies is correlated with the history of plasmas, high energy particles, and electromagnetic fields as measured on CRRES. The anomalies for each instrument on CRRES are compared with those from other instruments. The 674 anomalies, as a group, correlate well with high levels of high energy electron flux and poorly with every other environmental parameter
