The European-built Service Module (ESM) for NASA’s Artemis II mission is on a work stand inside a clean room inside the high bay of the Neil A. Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida on Jan. 12, 2022. Teams from NASA, Lockheed Martin, the European Space Agency and Airbus will prepare the service module to be integrated with the Orion crew module adapter and crew module, already housed in the facility. The powerhouse that will fuel and propel Orion in space, the ESM for Artemis II will be the first Artemis mission flying crew aboard Orion.
