STS-135 Commander Chris Ferguson and Doug Hurley visit with employees at the Shuttle Landing Facility.

At NASA's Kennedy Space Center in Florida, STS-135 Commander Chris Ferguson and Pilot Doug Hurley (on left) visit with employees at the Shuttle Landing Facility. The astronauts, along with Mission Specialist Sandra Magnus, were 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.
