The resulting gravity fed system, used through the remainder of the program, began release from a 300,000-US-gallon (1.1-million-litre) water tower at the launch site 6.6 seconds before main engine start through 7 feet (2.1 m) diameter pipes connected to the mobile launch platform.
STS-8 was the eighth NASA Space Shuttle mission and the third flight of the Space Shuttle Challenger. It launched on August 30, 1983, and landed on September 5, 1983, conducting the first night launch and night landing of the Space Shuttle program. It also carried the first African-American astronaut, Guion Bluford.
The Space Shuttle external tank (ET) carried the propellant for the Space Shuttle Main Engines, and connected the orbiter vehicle with the solid rocket boosters. The ET was 47 m (153.8 ft) tall and 8.4 m (27.6 ft) in diameter, and contained separate tanks for liquid oxygen and liquid hydrogen.
STS-51-F (also known as Spacelab 2) was the 19th flight of NASA's Space Shuttle program and the eighth flight of Space Shuttle Challenger.It launched from Kennedy Space Center, Florida, on July 29, 1985, and landed eight days later on August 6, 1985.
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 redline limit to initiate a shutdown is at 867 K. This limit increases to 980 K at T−1.3 s (5.3 s after Main Engine Start). Main Engine #3 (SN 2032) has been used on two previous flights with 2,412 seconds (40 min) of hot-fire time and a total of eight starts. This was the first flight for the HPOT on Main Engine (SSME) #3. [4]

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 ...
