Risk of Acute and Chronic Carbon Dioxide Exposure

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. Expedition 39 flight engineer Rick Mastracchio looks for a loose connection as he conducts troubleshooting…
