Spacecraft Health & Safety

The onboard and ground logic that detects failures and responds automatically to keep a spacecraft safe when the ground cannot react in time — vital across the long light-time to deep space.

A protective state a spacecraft autonomously enters when it detects a serious problem — pointing its solar arrays at the Sun and its antenna toward Earth, and waiting for instructions.

Continuously watching a spacecraft's telemetry against expected limits to catch anomalies early — the routine vigilance that keeps a mission alive.
