View of damaged Apollo 13 Service Module from the Lunar/Command Modules
This view of the damaged Apollo 13 Service Module (SM), with the Moon in the distant background, was photographed from the Lunar Module/Command Module following SM jettisoning. The Command Module (CM), still docked with the Lunar Module (LM), is in the foreground. An entire panel on the SM was blown away by the apparent explosion of oxygen tank number two located in Sector 4 of the SM. Three fuel cells, two oxygen tanks, and two hdyrogren tanks are located in Sector 4. The damaged area is forward (above) the S-band high gain antenna. The damage to the SM caused the Apollo 13 crewmen to use the LM as a "lifeboat". The LM was jettisoned just prior to Earth reentry by the CM.
