The Space Shuttle (actual name “Space Transportation System) was a reusable manned low Earth orbit vehicle. It consisted of the space plane which went into orbit and glided back to Earth, two Solid Rocket Boosters and the expendable fuel tank.
Shuttles were operated by NASA from 1981 to 2011, flying a total of 135 missions.
The missions ranged from launching satellites and interplanetary probes to delivering components for the International Space Station, and later delivering supplies and crew for the ISS.
There were originally 5 shuttles built, Enterprise, which had no orbital capability, Challenger, Columbia, Discovery and Atlantis. After Challenger was destroyed, Endeavour was built.
Dragon’s kit of Discovery can be built as a “cutaway”, using the clear parts to show the interiors, or as a standard display model. This model is also available in Dragon kit DRA 14705, which includes the 747 used to transport the shuttle from the landing area at Edwards AFB to the Kennedy Space Center.
