CAPE CANAVERAL, Fla. - At the Shuttle Landing Facility SLF at NASA’s Kennedy Space Center in Florida, a special plaque marks the nose gear wheel stop of space shuttle Atlantis. The 16-by-28-inch black granite plaque is the third to be permanently mounted, commemorating the final landings of each of the three orbiters. Atlantis completed the STS-135 mission by landing at the SLF on July 21, 2011, at 5:57 a.m. Atlantis flew 33 missions, completed 4,848 orbits of the Earth, traveled nearly 126 million miles and spent 307 days in space. Atlantis carried 207 astronauts to space. Photo credit: NASA/Charisse Nahser

CAPE CANAVERAL, Fla. - Space shuttle Atlantis begins its move from Orbiter Processing Facility Bay 1. The spacecraft is being moved into storage inside High Bay 4 of the nearby Vehicle Assembly Building at NASA's Kennedy Space Center in Florida. The work is part of the Space Shuttle Program's transition and retirement processing of the space shuttle fleet. A groundbreaking was held Jan. 18 for Atlantis' future home, a 65,000-square-foot exhibit hall in Shuttle Plaza at the Kennedy Space Center Visitor Complex. Atlantis is scheduled to roll over to the visitor complex in November in preparation for the exhibit's grand opening in July 2013. For more information, visit http://www.nasa.gov/transition.

CAPE CANAVERAL, Fla. – In Orbiter Processing Facility-1 at NASA’s Kennedy Space Center in Florida, United Space Alliance technicians position the forward reaction control system over space shuttle Atlantis during the system’s reinstallation on the shuttle. The system helped the shuttle maneuver while it was in orbit. Atlantis’ FRCS was removed and sent to White Sands Test Facility in New Mexico to be cleaned of its toxic propellants. The work is part of the Space Shuttle Program’s transition and retirement processing of the shuttle fleet. A groundbreaking was held Jan. 18 for Atlantis' future home, a 65,000-square-foot exhibit hall in Shuttle Plaza at the Kennedy Space Center Visitor Complex. Atlantis is scheduled to roll over to the visitor complex in November in preparation for the exhibit’s grand opening in July 2013. For more information, visit http://www.nasa.gov/shuttle.
