NASA Utilizes RS-25 and AJ10-190 Engines for Artemis Moon Missions
The Artemis program will employ the RS-25 and AJ10-190 engines, leveraging decades of proven technology for lunar missions. This choice prioritizes reliability as the U.S. aims to maintain its competitive edge in lunar exploration.

NASA's Artemis program will utilize RS-25 engines, previously used in Space Shuttle missions, for the Space Launch System (SLS) and AJ10-190 engines in the Orion capsule. The AJ10-190, operational since 1981, provides reliability and has a thrust range of 26 kN to 27 kN, crucial for manned lunar missions.
While Airbus develops the European Service Module (ESM) for Orion, challenges include integrating modern systems with legacy technology. The AJ10-190's design allows for operational simplicity, reducing development risks. However, future orders for additional ESM units depend on NASA's directives, impacting Europe's involvement in lunar exploration.
