STENNIS SPACE CENTER, Miss. -- NASA engineers successfully conducted the second in a series of RS-25 flight controller tests today. The test was reset after a facility issue, subsequently resolved, forced rescheduling of a May 16 hot fire. The 500-second test – more than eight minutes – was on the A-1 Test Stand and is designed to test the controller, the key modification to the former space shuttle engines that will be used on the core stage of the Space Launch System. NASA’s Space Launch System, which will take astronauts deeper into space than ever before, will be powered by four RS-25 engines. The first flight controller was tested in March.
