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:
“The true courage of civilized nations is readiness for sacrifice in the service of the state, so that the individual counts as only one amongst many. The important thing here is not personal mettle but aligning oneself with the universal.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
