RS-25 tested 420 seconds

STENNIS SPACE CENTER, Miss. -- NASA engineers successfully conducted a development test of the RS-25 rocket engine Thursday. The RS-25 will help power the core stage of the agency's new Space Launch System (SLS) rocket for the journey to Mars and beyond. The test of engine No. 0528 was for 420 seconds. The SLS rocket will be powered by four RS-25 engines, firing along with a pair of solid rocket boosters. NASA has conducted tests of the new booster at Orbital ATK's test facilities in Promontory, Utah, while all RS-25 developmental and flight engine tests will be conducted on the A-1 Test Stand at SSC.
