When the Orion spacecraft carries the first Artemis crews to the moon and back, it will rely on the European Service Module contributed by ESA (European Space Agency) to make the journey. The service module provides electrical power generation, propulsion, temperature control, and consumable storage for Orion, up to the moment it separates from the crew module prior to re-entry into Earth’s atmosphere.

For the first six Artemis missions—Artemis I through Artemis VI—NASA and ESA will use a refurbished Orbital Maneuvering System (OMS)  from the  as the European Service Module’s main engine. Beyond Artemis VI, NASA will need a new engine to support Orion.

That need will be met by the Orion Main Engine (OME) in development with Aerojet Rocketdyne (now L3 Harris), but before the OME can fly, all of its components must be thoroughly tested.
