System Reconfiguration
System Reconfiguration and Graceful Degradation Manager
Redundancy switching, load redistribution, and bypass routing for fault tolerance
Purpose
Reconfigure system paths and redundancy to work around failed components
Context
Component of L1-SLF within the Lunar Ark system
Principles
- ▸Redundancy switching activates backup systems when primary fails
- ▸Load redistribution balances demands across remaining operational systems
- ▸Graceful degradation prioritizes mission-critical functions when resources constrained
- ▸System state management tracks current configuration and available capabilities
Typical implementations
- ▸Spacecraft autonomous mode management (safe mode, survival mode hierarchies)
- ▸ISS Tier-1/Tier-2/Tier-3 automated contingency response
- ▸Power grid load shedding and reconfiguration systems
- ▸Data center failover and redundancy management
Lunar considerations
- ▸Preservation systems (cryo, genetic archive) have highest priority in degraded modes
- ▸Power budget reallocation critical during equipment failures
- ▸Some reconfigurations are irreversible - must be carefully validated before executing
- ▸100-year mission means system will operate in various degraded states throughout life
