Engine Removal Signals Completion of Successful Test Series

A work crew at NASA’s Stennis Space Center near Bay St. Louis, Mississippi removes RS-25 developmental engine E0525 from the Fred Haise Test Stand on April 9. Removal of the engine follows completion of the second and final 12-test series for lead engines contractor Aerojet Rocketdyne, an L3Harris Technologies company, to certify and build new RS-25 engines for NASA’s SLS (Space Launch System) rockets that will power future lunar missions, beginning with Artemis V. Through Artemis, NASA will establish the foundation for long-term scientific exploration at the Moon; land the first woman, first person of color, and first international partner astronaut on the lunar surface; and prepare for human expeditions to Mars for the benefit of all.
