Stennis' first hot fire test of 2023

NASA's newly redesigned RS-25 engine for future flights of the Space Launch System (SLS) rocket underwent its first hot fire test of the year Feb. 8 at the Stennis Space Center near Bay St. Louis, Miss. The series of testing supports production of RS-25 engines by Aerojet Rocketdyne. The engines will help power future Artemis missions to the Moon beginning with Artemis Vl. During the latest test, engineers fired the RS-25 engine for a full duration of about 8.5 minutes, the amount of time the engines must operate to help power SLS to space. The RS-25 engine also operated at 111% power for most of the test, the same level needed to lift SLS to orbit.
