  • A rocket engine firing. A blue flame is projecting from a bell-shaped nozzle with several pipes wrapped around it. The top of the nozzle is attached to a complex collection of plumbing, with the whole assembly covered in steam and hanging from a ceiling-mounted attachment point. Various pieces of transient hardware are visible in the background.

abstract
  • The engine produces a specific impulse (Isp) of in a vacuum, or at sea level, has a mass of approximately tonnes ( pounds), and is capable of throttling between 67% and 109% of its rated power level in one-percent increments. The RS-25 operates under temperatures ranging from to 3300 °C (6000 °F). On the Space Shuttle, the RS-25 was used in clusters of three engines mounted in the aft structure of the orbiter, with fuel being drawn from the external tank. The engines were used for propulsion during the entirety of the spacecraft's ascent, with additional thrust being provided by two solid rocket boosters and the orbiter's two AJ10-190 orbital maneuvering system engines. Following each flight, the engines were removed from the orbiter, inspected and refurbished before being reused on another mission.
