Bob Cabana, director of NASA's Kennedy Space Center in Florida, checks out the underside of space shuttle Discovery, following its final return from space. Touchdown on the Shuttle Landing Facility's Runway 15 was at 11:57 a.m. (EST) on March 9, 2011, bringing an end to the 13-day STS-133 mission to the International Space Station. 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.
