The Space Shuttle flight era lasted from 1981 to 2011 but its roots lie deep in the 1960s. Many ambitious plans for spaceplanes with airliner-type operation were proposed but the result was inevitably a compromise: an extraordinary vehicle that could have been even better.
1950s
NACA (NASA’s predecessor) studies with US Air Force flying at high altitudes and supersonic speed with X-15 research aircraft and plans the X-20 development vehicle capable of spaceflight. The X-20 was not built, but led to study of ‘wingless’ aircraft and 'lifting bodies'.
Mid-1960s
Several studies of reusable spaceplane designs.
1969
The Space Task Group was formed by President Richard Nixon to evaluate designs and to recommend a national space strategy. The goal was a common strategy for NASA, the Department of Defense, and commercial and scientific users.

Early 1970s
After weighing the best Shuttle design against development and operating costs, a system consisting of a reusable winged orbiter, reusable solid rocket boosters and an expendable external tank was chosen. This was less technically ambitious than earlier fully reusable designs, but also less costly to build.
1972
The Shuttle programme was formally launched by President Nixon.
North American Aviation (now Boeing Company) was selected as the prime contractor, including responsibility for the Orbiters. The contractor for the Solid Rocket Boosters was Morton Thiokol (now Alliant Techsystems). The External Tank contract was given to Martin Marietta (now Lockheed Martin). The ambitious main engines were developed by Rocketdyne (now Pratt & Whitney Rocketdyne).
24 September 1973
The Spacelab Memorandum of Understanding was signed in Washington DC between ESRO and NASA.
