CAPE CANAVERAL, Fla. – At the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida, STS-135 Pilot Doug Hurley stands in front of a T-38 training jet. Hurley, along with Commander Chris Ferguson and Mission Specialist Sandra Magnus, was at the center for the traditional post-flight crew return presentation. STS-135 Mission Specialist Rex Walheim was unable to attend the Kennedy event. In July 2011, Atlantis and its crew delivered to the International Space Station the Raffaello multi-purpose logistics module packed with more than 9,400 pounds of spare parts, equipment and supplies that will sustain station operations for the next year. STS-135 was the 33rd and final flight for Atlantis and the final mission of the Space Shuttle Program.
