Atmosphere Life-Support Simulator

Real spacecraft life support isn't a switch you flip — it's a mass balance you have to win, day after day. This simulator integrates real per-astronaut O2, CO2 and water rates against tunable subsystem capacities: an electrolysis generator running the true 2H2O → 2H2 + O2 stoichiometry, a CO2 scrubber, an optional Sabatier reactor recovering water from CO2 + H2, and a water-recycling loop. Load a real mission case study — ISS's near-closed ECLSS, Mir's partial loop, Apollo/Skylab's open-loop canisters, or Biosphere 2's undersized biology — or build your own configuration, then watch whether the numbers settle into genuine steady-state equilibrium or drift toward CO2 buildup, O2 depletion or water exhaustion.
