Crewed spacecraft

Crewed spacecraft are designed to support human life for the human spaceflight portion of the mission. Spacecraft for human spaceflight must have a human-rating certification as fit for purpose. Crewed spacecraft must have a pressurized, breathable atmosphere (usually between 345 mbar and 1 bar (1 atmosphere)) and be temperature-regulated (usually 20 to 24 °C (68 to 75 °F)). Crewed spacecraft include space capsules, spaceplanes, and space stations.
