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 10 May 2023, at 18:05 UTC (13:05 CDT, 14:05 EDT). This was the seventh 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 630 seconds, longer than the length of time (500 seconds) the engines must fire during an actual flight of NASA’s Space Launch System (SLS). Credit: NASA #RS25
