The Space Shuttle was NASA's partially reusable low Earth
orbital spacecraft. It included the Orbiter Vehicle, a pair of recoverable
solid rocket boosters (SRBs) and the expendable external tank containing liquid
hydrogen and liquid oxygen. The Shuttle was launched vertically, like a
conventional rocket, with the two SRBs operating in parallel with the OV's
three main engines, which were fueled from the ET. NASA designed six Orbiter
vehicles and named them, in order: Enterprise, Columbia, Challenger, Discovery,
Atlantis, and Endeavour. The Space Shuttle was retired from service upon the
conclusion of Atlantis' final flight on July 21, 2011. This high-quality
replica is crafted from plastic and comes with a wooden base. The length is 11"
and the wingspan is 4-1/2".
