Recovery Planning
Automated Recovery Plan Generation
Automated recovery plan generation is a software subsystem deployed on radiation-hardened NOR flash memory that determines multi-step action sequences to restore nominal operation after a fault. Operating at one watt of power with a 500,000-hour mean time between failures, the software derives authenticated recovery plans from system models and fault trees at rates up to 10 plans per day. Long-duration lunar surface deployments require autonomous fault recovery across a 100-year operational lifetime without reliance on real-time Earth intervention. The architecture embeds verification checkpoints between sequential recovery steps, coordinating directly with maintenance procedure execution routines and referencing historical deviation logs to resolve anomalies.
