NASA Tests In-Flight Capability of Artemis Moon Rocket Engine

NASA conducts the third RS-25 engine hot fire in a critical 12-test certification series on the Fred Haise Test Stand on Nov. 29. The test demonstrated a key capability necessary for flight of the SLS (Space Launch System) rocket during Artemis missions to the Moon and beyond. Crews gimbaled, or pivoted, the RS-25 engine around a central point during the almost 11-minute (650 seconds) hot fire. The gimbaling technique is used to control and stabilize SLS as it reaches orbit. Aerojet Rocketdyne, an L3Harris Technologies Company, and lead engines contractor for the SLS rocket, is incorporating new manufacturing techniques and processes, such as 3D printing, in production of new RS-25 engines for future deep space missions, beginning with Artemis V.
