The Space Shuttle program, officially called the Space Transportation System (STS), was the United States government's manned launch vehicle program from 1981 to 2011, administered by NASA and officially beginning in 1972.
How are the space shuttles constructed? Space shuttles are made up of many different parts, but the three main pieces are the rocket boosters, the fuel tank and the orbiter. There are two rocket boosters that are used to lift the shuttle off the ground and blast into space. The tank on the outside of the shuttle holds fuel to be used by the rocket boosters for launch.
