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 can counterfeit the deep tragedian,
Speak, and look back, and pry on every side,
Tremble and start at wagging of a straw,
Intending deep suspicion. Ghastly looks
Are at my service like enforced smiles,
And both are ready in their offices
At any time to grace my stratagems.”
—William Shakespeare (1564–1616)
