description abstractAbstract:
After two and one-half years of operational use, a bearing cage instability trend developed in a bearing in one of three Cassini reaction wheels. JPL responded to the indication of life-limiting wear through steps to manage RWA use, including tracking RWA performance, limiting RWA usage, using a software tool to manage reaction wheel biasing events, and providing a reaction wheel drag torque estimator to identify anomalous bearing drag conditions.
