NASA Administrator Charlie Bolden leads the STS-133 crew to media representatives waiting on the Shuttle Landing Facility at Kennedy Space Center in Florida to hear statements about space shuttle Discovery's final spaceflight mission. The STS-133 crew returned to Earth at 11:57 a.m. on Runway 15, completing a 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
