Technicians inside Kennedy Space Center's Orbiter Processing Facility-2 lower one of space shuttle Endeavour's recently removed fuel cells onto a waiting platform.

All three of Endeavour's fuel cells were removed and will be drained of fluids. The hydrogen and oxygen dewars which feed reactants to the fuel cells remain in Endeavour's midbody and will be purged with inert gases and vented down. The work is part of the Space Shuttle Program's transition and retirement processing of shuttle Endeavour, which 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. For more information, visit http://www.nasa.gov/shuttle. Photo credit: NASA/Glenn Benson
