United Space Alliance technicians secure the forward reaction control system back in place on space shuttle Atlantis.

In Orbiter Processing Facility-1 at NASA’s Kennedy Space Center in Florida, United Space Alliance technicians secure the forward reaction control system back in place on space shuttle Atlantis.

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.
