Saturn V SM
The Service Module provided the Command Module (CM) with essential supplies such as oxygen, water, fuel and electricity. The SM also acted as the CM's primary source of propulsion and was responsible for placing the spacecraft into lunar orbit as well as thrusting it back toward Earth at the end of the mission.
Buit by North American Rockwell, the Service Module was basically an aluminum cylinder that enclosed a compact labyrinth of tanks, fuel cells and cables. The CM and SM were joined for most of the lunar voyage and were referred to collectively as the Command and Service Modules (CSM).
