Looking along the underbelly toward the nose landing gear of space shuttle Atlantis checks in Orbiter Processing Facility Bay 1.

Looking along the underbelly toward the nose landing gear of space shuttle Atlantis, technicians complete weight and center-of-gravity checks in Orbiter Processing Facility Bay 1 at NASA’s Kennedy Space Center in Florida.

The work is part of the Space Shuttle Program’s transition and retirement processing of the shuttle fleet. A groundbreaking was held Jan. 18, 2012, 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 during November in preparation for the exhibit's grand opening in July 2013. For more information, visit http://www.nasa.gov/transition.
