|NASA ENDS ONE CHAPTER IN HUMAN SPACEFLIGHT, PREPARES FOR THE NEXT|
The Stennis Space Center conducted the final space shuttle main engine test on its A-1 Test Stand Friday. The A-1 Test Stand was the site of the first test on a shuttle main engine in 1975. Stennis will continue testing shuttle main engines on its A-2 Test Stand through the end of the Space Shuttle Program in 2010. The A-1 stand begins a new chapter in its operational history in October. It will be temporarily decommissioned to convert it for testing the J-2X engine, which will power the upper stage of NASA's new crew launch vehicle, the Ares I. Although this ends the stand’s work on the Space Shuttle Program, it will soon be used for the rocket that will carry America’s next generation human spacecraft, Orion.
