CAPE CANAVERAL, Fla. – Astronauts from Space Shuttle Atlantis’ STS-135 mission travel inside NASA’s silver Astrovan. From left are Commander Chris Ferguson and Mission Specialist Sandra Magnus. Since 1984, the Astrovan, a modified Airstream motor home, has carried shuttle crew members to the launch pads. The astronauts, along with Pilot Doug Hurley 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.
