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 30 March 2022, at 19:56 UTC (13:56 CDT, 14:56 EDT). The test is the fifth hot fire in the latest test series that began in December 2021, using the development engine No. 0525 to “gather performance data on a variety of new engine components manufactured with state-of-the-art fabrication techniques, like hot isostatic pressure bonding and selective laser melting, to reduce both the cost and time to build new engines”. The development engine No. 0525 was fired a full duration of about eight-and-a-half minutes (500 seconds), the same amount of time the engines must operate to help send NASA’s Space Launch System (SLS) to space.
