NASA conducted the test at its Stennis Space Center, which demonstrated the engine鈥檚 performance and reliability during a 500-second firing that reached 111% of its rated power level. This test marked the second flight-ready RS-25 engine produced using modern manufacturing techniques, including 3D printing, which reduce production costs by 30% compared to earlier RS-25 engines that powered the space shuttle.
The first four Artemis missions use upgraded RS-25 engines originally designed for the space shuttle program, while the fifth mission will debut the newly produced RS-25 engines.
