Guests managers and employees gather to watch shuttle Discovery return from space for the last time.

At NASA's Kennedy Space Center in Florida, invited guests, managers and employees gather near the Air Traffic Control Tower at the Shuttle Landing Facility (SLF) to watch shuttle Discovery return from space for the last time. Discovery touched down on Runway 15 at 11:57 a.m. EST, completing 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. Photo credit: NASA/Jim Grossmann
