RS-25 has successful test

STENNIS SPACE CENTER, Miss. -- The engine that will power America's next great rocket to deep space had its first successful test Friday at NASA's Stennis Space Center near Bay St. Louis, Miss. The RS-25, formerly the space shuttle main engine, fired up for 500 seconds on the A-1 test stand, providing NASA engineers critical data on the engine controller unit and inlet pressure conditions. This is the first hot fire of an RS-25 engine since the end of space shuttle main engine testing in 2009. Four RS-25 engines will power Space Launch System on future missions.
