The Space Shuttle is a retired, partially reusable low Earth orbital spacecraft system operated from 1981 to 2011 by the U.S. National Aeronautics and Space ...
The Space Shuttle program was the fourth human spaceflight program carried out by the U.S. National Aeronautics and Space Administration (NASA), which accomplished routine transportation for Earth-to-orbit crew and cargo from 1981 to 2011.
Early U.S. space shuttle concepts. Before the Apollo 11 Moon landing in 1969, NASA began studies of Space Shuttle designs as early as October 1968. The early studies were denoted "Phase A", and in June 1970, "Phase B", which were more detailed and specific.
Nuclear Ferry and Shuttle Orbiter docked to an Orbital Propellant Depot. The Space Transportation System (STS), also known internally to NASA as the Integrated Program Plan (IPP), [1] was a proposed system of reusable crewed space vehicles envisioned in 1969 to support extended operations beyond the Apollo program (NASA appropriated the name for its Space Shuttle Program, the only component of ...
The Space Shuttle external tank (ET) was the component of the Space Shuttle launch vehicle that contained the liquid hydrogen fuel and liquid oxygen oxidizer. During lift-off and ascent it supplied the fuel and oxidizer under pressure to the three RS-25 main engines in the orbiter. The ET was jettisoned just over 10 seconds after main engine ...
Smaller rocket engines on the craft's body provided propulsion in orbit and de-orbital burns, similar to the Space Shuttle's OMS pods. Unlike the Space Shuttle whose first orbital spaceflight was accomplished in April 1981, Buran, whose first and only spaceflight occurred in November 1988, had a capability of flying uncrewed missions, as well ...
The Space Shuttle orbiter ranks second among the world's first spaceplanes, preceded only by the North American X-15 and followed by the Buran, SpaceShipOne, and the Boeing X-37. Enterprise displaying the orbiter markings. The typeface used on the Space Shuttle orbiter was Helvetica. [26]
The 5-segment SRB, which would have required little change to the current shuttle infrastructure, would have allowed the space shuttle to carry an additional 20,000 lb (9,100 kg) of payload in a 51.6°-inclination orbit, eliminate the dangerous "Return-to-Launch Site" (RTLS) and "Trans-Oceanic Abort" (TAL) modes, and, by using a so-called "dog ...
