| | The Partnership - ch3-7 |
 | | Called CM for short, the command module was a multipurpose space cabin internally organized to function as a combined cockpit, office, laboratory, communications center, galley, sleeping quarters, and personal hygiene center. |
 | | The command-center module became the crew quarters for all phases of the mission, and the propulsion module held all redundant and orbital maneuvering systems. |
 | | The spacecraft consisted of three major components - the cosmonauts' cabin (descent vehicle), occupied during the launch and reentry phases of the flight; an orbital module, partitioned from the descent vehicle by an airtight hatch; and an instrument assembly module. |
