Service Module

A service module (or equipment module) is a spacecraft compartment containing a variety of support systems used for spacecraft operations. Usually located in the uninhabited area of the spacecraft, the service module is jettisoned upon the completion of the mission, and usually burns up during atmospheric reentry. The service module is the equivalent to the spacecraft bus assembly on unmanned spacecraft.

Famous quotes containing the word service:

    I like the silent church before the service begins, better than any preaching. How far off, how cool, how chaste the persons look, begirt each one with a precinct or sanctuary!
    Ralph Waldo Emerson (1803–1882)
