Life-Support Rationing: ECLSS Failure Triage Simulator

A partial life-support failure leaves a space station short of oxygen. Choose how the scarce supply is rationed across four habitat modules — equal split, mission-priority, or your own manual allocation — and watch each crew's blood oxygen respond in real time.

A partial failure in a space station's Environmental Control and Life Support System (ECLSS) cuts oxygen supply below total crew demand, forcing a real allocation decision across four habitat modules. This simulator models each crew member's blood oxygen saturation as a physiologically-motivated relaxation toward an equilibrium set by their module's supply ratio, so the ethical weight of "equal split," "mission priority," or your own manual rationing shows up immediately as falling — or recovering — SpO₂, not as an abstract score.
