Employees admire space shuttle Atlantis as the landing convoy crew makes the vehicle safe for towing to its processing hangar at NASA's Kennedy Space Center in Florida. Atlantis' final return to Earth on the Shuttle Landing Facility's Runway 15 at NASA's Kennedy Space Center in Florida occurred at 5:57 a.m. EDT completing the 13-day, 5.2-million-mile STS-135 mission.

Securing the space shuttle fleet's place in history, Atlantis marks the 26th nighttime landing of NASA's Space Shuttle Program and the 78th landing at Kennedy. 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 is the 33rd and final flight for Atlantis and the final mission of the Space Shuttle Program. For more information, visit www.nasa.gov/mission_pages/shuttle/shuttlemissions/sts135/index.html.
