Fast Anomaly Response vs Operational Understanding
Pre-certify reversible containment actions as safe states under IEC 61508 so operators can stabilize spacecraft immediately without prejudging fault diagnosis.

Business Context
When spacecraft anomalies occur, rapid action can prevent equipment damage or mission loss. However, acting before operators understand the system condition can introduce incorrect commands or obscure diagnostic evidence. Waiting for complete analysis improves understanding but can allow the anomaly to worsen.
Space TRIZ Resolution
Immediate response should focus on reversible containment while detailed diagnosis continues. Predefined protective actions can stabilize the spacecraft without committing to a specific fault interpretation. Once additional telemetry and analysis clarify the condition, operators or autonomous systems can select the appropriate recovery path.
Applicable TRIZ Principles
Principle 1 – Segmentation separates immediate stabilization from detailed recovery.
Principle 10 – Prior Action prepares safe containment actions before anomalies occur.
Principle 23 – Feedback progressively refines recovery decisions as diagnostic information improves.
Expected Outcome
Faster anomaly containment
Better diagnostic accuracy
Lower risk of incorrect recovery
Reduced anomaly propagation
Decision Indicators
Early indicators include:
Operators must choose between immediate action and diagnostic investigation.
Emergency commands are difficult to reverse.
Valuable fault evidence is lost during early recovery actions.
Teams delay stabilization while determining root cause.
Similar anomalies repeatedly require improvised initial responses.
