Space shuttle main engine No. 0525 is lifted from the A-2 Test Stand at Stennis Space Center against the backdrop of the new A-3 Test Stand under construction, offering a glimpse of the past and future in the nation's space exploration program. With the shuttle program set to end in 2010, Stennis conducted the last planned space shuttle main engine test on July 29 and now is deactivating the A-2 Test Stand to a safe 'standby' status.
