NASA Successfully Tests Rocket Engine Capabilities in Hot Fire Test

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.
