CAPE CANAVERAL, Fla. – Inside Orbiter Processing Facility-2 at NASA’s Kennedy Space Center in Florida, one of space shuttle Endeavour’s payload bay doors is closed as United Space Alliance technicians monitor the progress of the second door’s closure. Endeavour’s payload bay doors are being closed for the final time. The work is part of Transition and Retirement of the remaining space shuttles, Endeavour and Atlantis. Endeavour is being prepared for public display at the California Science Center in Los Angeles. Its ferry flight to California is targeted for mid-September. Endeavour was the last space shuttle added to NASA’s orbiter fleet. Over the course of its 19-year career, Endeavour spent 299 days in space during 25 missions.
