Autonomous Spacecraft Health Management: Results From IM-2 Lunar Mission

Modern Spacecraft are highly complex systems, which must be able to operate safely and reliably with a high degree of autonomy under numerous environmental conditions. Restricted telemetry bandwidth and long turn-around time makes efficient and timely onboard detection of anomalies paramount. In this paper, we present Active Vigilance®, an advanced anomaly detection system for multi-channel time-series data, which can operate within strict power and computational constraints. Active Vigilance® was integrated as part of a secondary payload on the Commercial Lunar Payload Services (CLPS) mission IM-2. We will describe the experiment setup and present results of payload experiments, which were carried out during the transit from Earth orbit to lunar orbit. We also report results of experiments with the R2U2 runtime-monitor and an autonomous, logic-based decision making and mitigation planning component. Our Active Vigilance® Anomaly Detection System was successfully operating during all transit experiments, processing live data obtained from the payload hardware and software system
