SLS RS-25 Engine Test, 23 May 2023

An Aerojet Rocketdyne RS-25 rocket engine was tested on the Fred Haise Test Stand (formerly A-1 Test Stand) at the John C. Stennis Space Center in Mississippi, on 23 May 2023, at 18:48 UTC (13:48 CDT, 14:48 EDT). This was the eighth 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 #RS25
