The mission is composed of NASA's Orion spacecraft with the European Service Module (ESM).
The ESM supports the crew module from launch to separation before re-entry. It provides propulsion capability in space for orbital transfer and altitude control. In addition to the water and oxygen needed for a habitable environment, it generates and stores electrical power and maintains the temperature of the vehicle's systems and components. The module can also carry unpressurised cargo and scientific payloads.
ARTEMIS 1 will perform a flyby of the Moon, using lunar gravity to gain speed and propel itself 70 000 km beyond the Moon, almost half a million km from Earth, further than any human being has ever travelled.
ALTER supplied the electronic components on board the European Service Module for both ARTEMIS 1 and 2, which will be launched in 2024.
