June 23 (UPI) -- NASA fired up a full-duration test of its new RS-25 engine that will power the Space Launch System rocket on Artemis missions to the moon, the space agency announced Monday.
NASA tested RS-25 engine No. 20001 on Friday at the Fred Haise Test Stand at NASA's Stennis Space Center at Bay St. Louis in Mississippi. The full-duration "hot fire" test was the first since NASA completed certification testing for new production RS-25 engines last year.
The engine, built by contractor L3Harris Technologies -- formerly Aerojet Rocketdyne -- was fired up for nearly eight-and-a-half minutes. That is the same amount of time it would take four RS-25 engines to launch an SLS rocket, sending astronauts aboard the Orion into orbit. The engine was also fired up to the 111% power level to test its limits.
The test was conducted by a team from NASA, L3Harris and Syncom Space Services, which is the contractor for site facilities. All RS-25 engines are being tested and proven flightworthy at NASA Stennis after the space agency completed its RS-25 certification test series in April 2024.
