Aerojet Rocketdyne and NASA have successfully completed a series of certification tests for the new RS-25 production engines that will power NASA’s Space Launch System (SLS) exploration rocket for Artemis missions. The test series, which began in February and ended in June, ensured that the new engines will perform with the same reliability and robustness as their predecessors. The SLS core stage is powered by four Aerojet Rocketdyne RS-25 engines, each capable of generating more than 500,000 pounds of thrust. The newly manufactured engines are scheduled to begin delivery to NASA in 2024 and will make their debut on the Artemis V mission.
