Lighting up the Night

Year 2015 got off to a blazing start as NASA conducted its first test of an RS-25 rocket engine on the A-1 Test Stand at Stennis Space Center on Jan. 9, 2015. The 500-second test provided critical data on engine performance. RS-25 engines will help power the core stage of NASA’s new Space Launch System vehicle, being developed to carry humans deeper into space than ever before.
