SLS RS-25 Engine Test, 15 June 2023

An Aerojet Rocketdyne RS-25 rocket engine (RS-25 Engine 10001) was tested on the Fred Haise Test Stand (formerly A-1 Test Stand) at the John C. Stennis Space Center in Mississippi, on 15 June 2023, at 17:55 UTC (12:55 CDT). This was the eleventh hot fire test in a planned 12-test series of the newly redesigned RS-25 engines that will be used beginning with Artemis V. The test had a planned duration of 500 seconds, the same amount of time the engines must fire during an actual flight of NASA’s Space Launch System (SLS). Credit: NASA
