NASA Tests Powerful Engine for Future Moon Missions
NASA engineers at the Stennis Space Center in Bay St. Louis, Mississippi, conducted a hot fire test of the RS-25 engine on October 21, 2026. The test lasted for almost eight-and-a-half minutes, simulating the engine's performance during a launch of the Space Launch System (SLS) rocket, which will be used for future Artemis missions to the moon.
The engine tested, RS-25 number 10001, ran at 111% power. On each Artemis mission, four RS-25 engines work together and produce up to 2 million pounds of combined thrust to help launch the SLS rocket. The test helps prove the engine is ready to fly and gives engineers data on how it performs.
The RS-25 engine is a critical component of the SLS rocket, which will carry astronauts to the moon as part of the Artemis program. The engine's performance will be crucial in ensuring the success of future moon missions.
The test was a significant milestone in the development of the SLS rocket and the Artemis program. It demonstrates NASA's commitment to advancing space exploration and pushing the boundaries of what is possible.
The data collected during the test will be used to improve the performance and reliability of the RS-25 engine, which will be used in future missions to the moon. This will help ensure the success of the Artemis program and pave the way for future human exploration of the moon.
