SLS RS-25 Engine Test, 27 March 2024

An Aerojet Rocketdyne RS-25 rocket engine (RS-25 developmental engine E0525) was tested on the Fred Haise Test Stand (formerly A-1 Test Stand) at the John C. Stennis Space Center in Mississippi, on 27 March 2024, at 18:10 UTC (13:10 CDT). This was the 5th test using a new production engine nozzle providing additional performance data on the upgraded unit and the 11th hot fire test out of the 12 planned in the final round of certification testing ahead of production of an updated set of engines for NASA’s Space Launch System (SLS) that will be used beginning with Artemis V. The test had a planned duration of 500 seconds, with the RS-25 engine running up to 113% power level. Credit: NASA #RS25
