An engine-handling device is lowered to the floor of the SSME Processing Facility, the engine shop at NASA’s Kennedy Space Center in Florida. The fixture was used to rotate the Pratt and Whitney Rocketdyne space shuttle main engine, or SSME, at right, into a horizontal position. This engine and the one at left are secured on portable workstands before being transferred into transportation canisters.

The engine is one of the last SSMEs remaining at Kennedy and is being prepared for shipment to NASA's Stennis Space Center in Mississippi. The first two groups of engines were shipped from Kennedy to Stennis in November 2011 and January 2012 the remaining engines are scheduled to depart on April 9. Altogether, 15 shuttle-era engines will be stored at Stennis for reuse on NASA’s Space Launch System heavy-lift rocket, under development. Photo credit: NASA/Tim Jacobs
