The Space Shuttle was a partially reusable low Earth orbital spacecraft system operated by NASA (the National Aeronautics and Space Administration). Its official program name was Space Transportation System (STS), taken from a 1969 plan for a system of reusable spacecraft of which it was the only item funded for development. [ 1 ]
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 ...
The Space Shuttle Columbia was lost as it returned from a two-week mission when previously detected damage to the shuttle's thermal protection system (TPS) resulted in the spacecraft breaking apart during reentry at an altitude of just under 65 km and a speed of about Mach 19. Investigation revealed that a piece of foam insulation had fallen ...
Space shuttle program ends After the Columbia disaster, shuttle flights were again grounded. On Jan. 14, 2004, President George W. Bush announced a “new vision” for the nation’s space ...
The Space Shuttle program originated in the late 1960s as an attempt to reduce the cost of spaceflight ... Shuttle flight ALT-1: Taxi test #1: February 15, 1977 89 ...
The original intention was to compensate for this lower payload by lowering the per-launch costs and a high launch frequency. However, the actual costs of a Space Shuttle launch were higher than initially predicted, and the Space Shuttle did not fly the intended 24 missions per year as initially predicted by NASA.

The space shuttle project was forged in the optimism of NASA’s Apollo program, which landed 12 astronauts on the surface of the moon and bested America’s Soviet rivals during the Cold War.
