ISS Life Support Cooperation Network — 2D

Space station modules built by different agencies don't run separate air on separate schedules — Inter-Module Ventilation fans physically tie the US, Russian and partner segments into one shared atmosphere loop. This 2D simulator models three connected compartments (a NASA lab with a CDRA CO₂ scrubber, a passive node hub, and a Roscosmos segment with a Vozdukh scrubber) as a real compartmental mass-balance system: crew respiration adds carbon dioxide, each agency's scrubber removes it from its own module, and the IMV fan flow you control exchanges air between neighbours. A pannable, zoomable duct schematic, a live per-module bar readout and a time-series graph all track the same three-compartment ODE, so you can watch whether switching either scrubber off and tuning ventilation keeps the whole station under the 5.3 mmHg alarm limit or lets it climb.
