RS-25 undergoes latest test

STENNIS SPACE CENTER, Miss. – A team of operators conducted another successful 500-second RS-25 hot fire on the A-1 Test Stand at Stennis Space Center (SSC) in South Mississippi on Oct. 11, the fourth in a series that will extend into 2019. Once again, the hot fire features an acceptance test of an RS-25 engine controller for use on a future flight of NASA’s new Space Launch System (SLS) rocket. Four RS-25 engines, firing simultaneously, will provide a combined 2 million pounds of thrust to help launch the new rocket. NASA has been testing RS-25 engines at SSC for SLS use since early 2015.
