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 ...

It was used on the Space Shuttle orbiter (or simply Space Shuttle) for orbital insertion, manoeuvring the orbiter in space, and the deorbit burn. The AJ10-190 engines could be reused for up to 100 missions. Diagram of an RS-25 (or Space Shuttle Main Engine), that used a twin shaft staged combustion cycle. There were three of these on the back ...
A series of launch vehicles was proposed, based on the proposed Space Transportation Main Engine (STME) liquid-fuel rocket engine. The STME was to be a simplified, expendable version of the RS-25 engine. The NLS-1 was the largest of the three proposed vehicles and would have used a modified Space Shuttle external tank for its core
Hybrid-propellant rockets use a combination of solid and liquid propellant, typically involving a liquid oxidizer being pumped through a hollow cylinder of solid fuel. All current spacecraft use conventional chemical rockets (solid-fuel or liquid bipropellant) for launch, though some [note 3] have used air-breathing engines on their first stage ...
The two solid rocket motors, each weighing 104,000 pounds and the size of a Boeing 757 fuselage, were trucked from the Mojave Air and Space Port over two days. Space shuttle Endeavour's rockets ...
Most rocket engines are internal combustion heat engines (although non-combusting forms exist). [43] Rocket engines generally produce a high-temperature reaction mass, as a hot gas, which is achieved by combusting a solid, liquid or gaseous fuel with an oxidiser within a combustion chamber. [ 44 ]
As fuel and oxidiser are burned in the rocket's engines, helium fills the resulting empty space in the tanks, maintaining the overall pressure inside. Because it is non-reactive, it can safely ...
