Employees and photographers turn out for a close look at space shuttle Discovery as it approaches Orbiter Processing Facility-2 at NASA's Kennedy Space Center in Florida. Discovery is attached to a purge unit that pumps conditioned air into the shuttle while it is towed. In the background, the 525-foot-tall Vehicle Assembly Building towers over the processing bays. Discovery touched down on the Shuttle Landing Facility's 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
