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 ...
A new feature for the engine is the ability to throttle from 100% to 70%. [7] The engine's 150:1 thrust-to-weight ratio is the highest ever achieved for a rocket engine. [8] [9] The first flight of the Merlin 1D engine was also the maiden Falcon 9 v1.1 flight. [10]

Spacecraft propulsion [note 1] is any method used to accelerate spacecraft and artificial satellites. Orbital launch systems are rockets and other systems capable of placing payloads into or beyond Earth orbit. All launch vehicle propulsion systems employed to date have been chemical rockets falling into one of three main categories:
To keep the engine thrust values consistent with previous documentation and software, NASA kept the originally specified thrust at 100%, but had the RS-25 operate at higher thrust. RS-25 upgrade versions were denoted as Block I and Block II. 109% thrust level was achieved with the Block II engines in 2001, which reduced the chamber pressure to ...
The Mercury-Redstone Launch Vehicle, designed for NASA's Project Mercury, was the first American crewed space booster.It was used for six sub-orbital Mercury flights from 1960–1961; culminating with the launch of the first, and 11 weeks later, the second American (and the second and third humans) in space.
Propelled by 4 RS-25 engines, the stage generates approximately 7.44 MN (1,670,000 lb f) of thrust, about 25% of the Space Launch System's thrust at liftoff, for approximately 500 seconds, propelling the stage alone for the last 375 seconds of flight. The stage lifts the rocket to an altitude of approximately 162 km (531,380 ft) before ...
