First RS-25 test series done

STENNIS SPACE CENTER, Miss. -- A former Space Shuttle Main Engine, 0525, that never pushed a Space Shuttle into orbit completed its seventh static fire Thursday in South Mississippi and will now be replaced by flight engine 2059 on the A-1 Test Stand for the next test series. NASA's Space Launch System program will continue high-tempo testing of Aerojet Rocketdyne RS-25 engines at SSC through next year in preparation for the SLS vehicles first flight planned for 2018.
