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 ...

[15] [23] [21] [24] RS-25 engines (first used on the Space Shuttle) used a simpler form of staged combustion cycle. [25] Several Russian rocket engines, including the RD-180 [ 22 ] and the RD-191 did as well.
It was to be 8.4 meters in diameter, longer than the Space Shuttle external tank, and powered by four RS-25 engines, a configuration broadly similar to the core stage as built. [34] The NASA Authorization Act of 2010 directed NASA to, where practicable, reuse Space Shuttle and Constellation program parts and contractors.
Rocketdyne RS-25 Space Shuttle Main Engine (SSME) (LH2/LOX) The main engine for the Space Shuttle, also used on the Space Launch System; Rocketdyne RS-27A (RP-1/LOX) Used by the Delta II/III and Atlas ICBM; Rocketdyne RS-56 (RP-1/LOX) Used by the Atlas II first stage; Rocketdyne RS-68 (LH2/LOX) Used by the Delta IV first stage
The positioning had to be precise. The shuttle's nose was raised 200 feet into the night sky so that the rudder could clear 80 feet of space. Endeavour was then turned 17 degrees clockwise to ...
RS-25 Space Shuttle Main Engines Pratt & Whitney Rocketdyne. RL10 (LH2/LOX) An American Society of Mechanical Engineers (ASME) Historic Landmark developed by Pratt & Whitney. Used on the Saturn I, the upper stage of the Delta IV, the Centaur upper stage for the Atlas and Titan rockets and on the vertical-landing McDonnell Douglas DC-X "Delta ...
RS-25 (LH 2 /LOX) – Previously known as the Space Shuttle main engine (SSME), it was the reusable main engine developed by Rocketdyne for the now-retired Space Shuttle. Remaining RS-25D engines are planned for use on early Space Launch System rocket launches after which an expendable version, RS-25E will be developed for follow-on SLS launches.
