What is anomaly detection in space systems?

• A. Routine monitoring of subsystem performance.
• B. Predicting future mission trajectories.
• C. Identifying unusual or unexpected behavior indicating faults or threats.
• D. Scheduling maintenance windows.

Answer: (C)

Anomaly detection in space systems is recognizing unusual or unexpected behavior that could indicate faults, degraded performance, or potential threats. Spacecraft continuously generate telemetry from many subsystems, so engineers establish a baseline of normal operation—typical ranges, rates of change, and how sensors relate to each other. When a reading or pattern deviates from that baseline, the system flags it as an anomaly, prompting investigation, fault isolation, or autonomous corrective actions before a failure or mission risk occurs. This focus on identifying deviations sets it apart from routine monitoring (which tracks normal performance without specifically flagging unusual patterns), trajectory prediction, or maintenance scheduling.
