A 420-second test of RS-25 engine No. 0528 was held Thursday at NASA’s Stennis Space Center in Hancock County.
The rocket will help power the core stage of NASA’s new Space Launch System rocket to take American astronauts deeper into space than they have ever journeyed and to Mars.
The new SLS rocket will be powered at launch by four RS-25 engines like the one tested, firing in conjunction 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 Stennis. The tests are crucial to ensure the RS-25 engines will perform as needed.
The test was conducted by a team of NASA, Aerojet Rocketdyne and Syncom Space Services personnel and it was the third in a six-test developmental series.
