NASA's Artemis 2 will lift off on the Space Launch System powered by four RS-25 engines: three refurbished from the Space Shuttle program and one making its first flight. Collectively these engines bring a combined 22 previous shuttle missions to the Artemis effort, and, as SLS is fully expendable, the engines will be dropped into the Atlantic about 10 minutes after launch.
NASA conducted a "hot fire" test to certify the RS-25 engines for its Artemis moon-rocket program. The test, which lasted over nine minutes, aimed to collect data on the performance of key engine components. The engines will be used to power the core stage of the Space Launch System (SLS) rockets, with the goal of flying astronauts to the moon in future Artemis missions. The certification process will continue with a series of 12 tests planned through 2024.
NASA successfully tested the RS-25 rocket engine's maneuverability, also known as gimballing, as part of certification tests for an engine upgrade for the agency's Space Launch System (SLS) rocket for the Artemis program. The test involved revolving the engine around slowly at first and then making rapid moves to stay in position for a couple of seconds around the pitch and yaw axes. The engine generated a peak thrust of 418,000 pounds, equal to the power required during an Artemis flight, and was fired for 720 seconds, longer than the mission profile.
