Discovery and its six-member crew landed on the Shuttle Landing Facility's Runway 15 at 11:57 a.m. EST, bringing an end to the 13-day, 5.3-million-mile mission to the International Space Station.

STS-133 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
