Astronauts from Space Shuttle Atlantis’ STS-135 mission travel inside NASA’s silver Astrovan. Seated on the right are Commander Chris Ferguson and Mission Specialist Sandra Magnus while facing opposite is Pilot Doug Hurley. Since 1984, the Astrovan, a modified Airstream motor home, has carried shuttle crew members to the launch pads. The astronauts 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.
