Aviation News – The Orion European Service Module (ESM-2) has officially been declared “go” for flight, marking a definitive milestone for the Artemis II mission. This critical integration ensures that the first crewed journey to the Moon in over five decades is prepared to sustain human life in the harsh environment of deep space.
Developed by Airbus on behalf of the European Space Agency (ESA), the ESM-2 serves as the primary powerhouse for NASA’s Orion spacecraft. The module was finalized and fuelled following years of development and testing across ten European nations. This collaboration represents a historic shift in lunar exploration, as the mission—scheduled to launch from Kennedy Space Center—places the safety of a multinational crew directly into the hands of European-built systems.
The mission will carry NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, alongside Canadian Space Agency (CSA) astronaut Jeremy Hansen, on a 10-day journey. This flight follows the success of the uncrewed Artemis I test in 2022, but significantly raises the stakes by transitioning from a hardware demonstration to a crewed lunar flyby. The ESM-2 will be responsible for the trans-lunar injection burn, the maneuver required to propel the crew out of Earth’s orbit toward the Moon.
Technically, the ESM-2 functions as the “heart and lungs” of the spacecraft. It features a complex propulsion system comprised of 33 engines, including a repurposed Space Shuttle orbital maneuvering engine. Beyond thrust, its four solar array wings generate 11.2 kW of power, while internal systems regulate thermal control and provide the breathable air and water necessary for the four-person crew to survive the duration of the mission.
