ISS Life Support Cooperation Network

Interactive 3D model of how partner-agency modules on a space station share one life-support loop: toggle the US CDRA and Russian Vozdukh CO2 scrubbers and tune the inter-module ventilation flow to see cooperative air exchange stop a carbon-dioxide spike.

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 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. Switch either scrubber off and watch whether the interconnected ventilation — cooperation, mechanically — keeps the whole station under the 5.3 mmHg alarm limit or lets it climb.

⚙ Under the hood

Interactive 3D model of three interconnected space-station modules -- a US lab with a CDRA scrubber, a passive node hub and a Russian segment with a Vozdukh scrubber -- sharing one CO2 loop through Inter-Module Ventilation fans. Toggle either scrubber off and tune the fan flow to see whether cooperative ventilation keeps the whole station under the alarm limit.
