STS-135 will be the 33rd flight of Atlantis, the 37th shuttle mission to the space station, and the 135th and final mission of NASA's Space Shuttle Program. Photo credit: NASA

STS135-S-090 (8 July 2011) --- Space shuttle Atlantis and its four-member STS-135 crew head toward Earth orbit and rendezvous with the International Space Station.
