The Orbital Maneuvering System (OMS) is a system of hypergolic liquid-propellant rocket engines used on the Space Shuttle and the Orion spacecraft.Designed and manufactured in the United States by Aerojet, [1] the system allowed the orbiter to perform various orbital maneuvers according to requirements of each mission profile: orbital injection after main engine cutoff, orbital corrections ...
The AJ10-190 engine was used on the Space Shuttle Orbital Maneuvering System (OMS) for orbital insertion, on-orbit maneuvers, and de-orbiting, first flown in 1981. They produced 26.7 kilonewtons (6,000 lb f ) of thrust with a specific impulse ( I sp ) of 316 seconds. [ 6 ]
These included the 64 seconds OMS-2 burn which pushed Atlantis into a 230 x 158 km orbit and the NC-1 engine firing for 94 seconds to adjust the shuttle's orbital path to match with the Space Station. The NC-1 firing altered the shuttle's velocity by about 144.7 ft/s (44.1 m/s).
Three Space Shuttle Main Engines (SSMEs) were mounted on the orbiter's aft fuselage in the pattern of an equilateral triangle. These three liquid-fueled engines could be swiveled 10.5 degrees vertically and 8.5 degrees horizontally during the rocket-powered ascent of the orbiter in order to change the direction of their thrust.

[38] [39] After MECO and ET separation, the orbiter executed an OMS-2 engine firing to circularize the orbit, and put it on track to the International Space Station. [41] The crew opened the payload bay doors, deployed the K u antenna, checked out and activated the shuttle's robotic arm , and downlinked the video footage taken during external ...
The RS-25 engine consists of pumps, valves, and other components working in concert to produce thrust. Fuel (liquid hydrogen) and oxidizer (liquid oxygen) from the Space Shuttle's external tank entered the orbiter at the umbilical disconnect valves and from there flowed through the orbiter's main propulsion system (MPS) feed lines; whereas in the Space Launch System (SLS), fuel and oxidizer ...
