NASA astronauts Scott Kelly (left) and Terry Virts (right) work on a Carbon Dioxide Removal Assembly (CDRA) inside the station’s Japanese Experiment Module. The CDRA system works to remove carbon dioxide from the cabin air, allowing for an environmentally safe crew cabin.

Hostile, enclosed spaceflight environments (including space vehicles and suits) do not have the benefit of natural carbon dioxide (CO2) removal. In these environments, equipment (e.g., the Carbon Dioxide Removal Assembly, lithium hydroxide, and amine systems) control CO2 levels and mitigate consequences of elevated CO2 exposure.
