The
Orbital Maneuvering System, or
OMS, is a system of
rocket engines used on the
Space Shuttle for
orbital injection[?] and modifying its orbit. It consists of two "packs" at the back of the Shuttle, the large lumps on either side of the
vertical stabilizer[?]. Each pack contains a single 6,000 pounds thrust engine burning
hydrazine, which can be reused for 100 missions and is capable of 1,000 starts and 15 hours of firing. The OMS pods also contain the rear set of
RCS engines as well, which are referred to as the
OMS/RCS.
Orbital maneuvering system can be used to describe any system for moving about in orbit, so the term is found in non-Shuttle related topics as well.
