3D Space Habitat Life Support

The same real closed-loop mass-balance simulation as the 2D version — real per-astronaut O2/CO2/water rates, real electrolysis and Sabatier stoichiometry, real historical mission case studies — rendered as a free-orbit 3D cutaway of a habitat module. Animated particles flow visibly through the CO2 scrubber, Sabatier reactor and electrolysis unit, and the cabin atmosphere itself is color-coded live by O2 and CO2 concentration, so you can watch the loop reach equilibrium or drift toward failure from any angle.
