CAPE CANAVERAL, Fla. - The aft end of space shuttle Discovery is connected to a purge unit, one of the vehicles in the landing convoy at NASA's Kennedy Space Center in Florida. A purge unit pumps conditioned air into a shuttle after landing. Preparations are under way to tow Discovery from the Shuttle Landing Facility to Orbiter Processing Facility-2. Discovery touched down on Runway 15 at 11:57 a.m., bringing an end to its 39th and final spaceflight mission, STS-133. Discovery and its six-member STS-133 crew delivered the Permanent Multipurpose Module, packed with supplies and critical spare parts, as well as Robonaut 2, the dexterous humanoid astronaut helper, to the International Space Station. Inside the processing facility, Discovery will be prepared for future public display. Photo credit: NASA/Jack Pfaller
