Testing of RS-25 completed

STENNIS SPACE CENTER, Miss. - NASA completed developmental engine testing March 30 with a full-duration RS-25 hot fire, to support future engines that will launch Space Launch System (SLS) astronauts deeper into space than ever. Operators fired RS-25 engine No. 0525 for about eight-and-a-half minutes (500 seconds) and up to 111% power level on the Fred Haise Test Stand at NASA’s Stennis Space Center (SSC). The March 30 hot fire completed the fourth developmental test series and sets Aerojet Rocketdyne, lead contractor for NASA’s SLS engines, on pace to produce new RS-25s for future use.
