North American Apollo CSM
The Command/Service Module (CSM) was
a spacecraft built for NASA by North Americ-
an Aviation. It was one of the two spacecraft
that were utilized for the Apollo program,
along with the Lunar Module, to land astro-
nauts on the Moon. Together they were
called the Apollo spacecraft. After the conclu-
sion of the Apollo program, the CSM saw ser-
vice as a ferry for the Skylab program and for
the Apollo-Soyuz Test Project where a CSM
rendezvoused in orbit with a Soviet Soyuz
spacecraft.
The spacecraft, as its name suggests, con-
sisted of two segments, the command mod-
ule (reentry capsule) which housed the crew
and the equipment needed for re-entry and
splashdown, and a service module that
provided propulsion, electrical power and
storage for various consumables required
during a mission. The service module would
be cast off and allowed to burn up in the at-
mosphere before the command module re-
entered and brought the crew home.
