Background
ESA built the European Service Module 2 (ESM-2) that provides power, propulsion and life support for Orion on Artemis II. Manufactured by Airbus in Bremen, it represents a contribution from 13 European nations and is ESA's largest single role in US human spaceflight.
Founded in 1975, ESA coordinates the space activities of 22 member states. The service module programme grew from the Automated Transfer Vehicle (ATV) used to resupply the ISS, recycling heritage hardware and expertise into a deep-space role.
ESA's involvement anchors European relevance in the Artemis programme even as the Lunar Gateway — another major ESA commitment — faces cancellation. The agency's ability to deliver safety-critical hardware on schedule has reinforced its standing as NASA's most capable international partner.
