The crew transport vehicle pulls up to space shuttle Discovery on the Shuttle Landing Facility's Runway 15 at NASA's Kennedy Space Center in Florida. STS-133 Commander Steve Lindsey, Pilot Eric Boe, and Mission Specialists Alvin Drew, Steve Bowen, Michael Barratt and Nicole Stott will undergo brief medical checks in the crew transport vehicle before they walk around the spacecraft that brought them safely home. Discovery's final return from space completed the 13-day, 5.3-million-mile STS-133 mission. Main gear touchdown was at 11:57:17 a.m., followed by nose gear touchdown at 11:57:28, and wheelstop at 11:58:14 a.m.

Discovery and its six-member 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 orbiting outpost. STS-133 was Discovery's 39th and final mission. This was the 133rd Space Shuttle Program mission and the 35th shuttle voyage to the space station. Photo credit: NASA/Kim Shiflett
