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 24 February 2022, at 19:18 UTC (13:18 CST, 14:18 EST). 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. The test is the fourth 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”.
