Galileo spacecraft anomaly and safing recoveryA high-level anomaly recovery plan which identifies the steps necessary to recover from a spacecraft 'Safing' incident was developed for the Galileo spacecraft prior to launch. Since launch, a total of four in-flight anomalies have lead to entry into a system fault protection 'Safing' routine which has required the Galileo flight team to refine and execute the recovery plan. These failures have allowed the flight team to develop an efficient recovery process when permanent spacecraft capability degradation is minimal and the cause of the anomaly is quickly diagnosed. With this previous recovery experience and the very focused boundary conditions of a specific potential failure, a Gaspra asteroid recovery plan was designed to be implemented in as quickly as forty hours (desired goal). This paper documents the work performed above, however, the Galileo project remains challenged to develop a generic detailed recovery plan which can be implemented in a relatively short time to configure the spacecraft to a nominal state prior to future high priority mission objectives.
