The European Service Module is powering Orion to the Moon and back, providing electricity, propulsion, keeping electronics and the crew module at the right temperature. On the next Artemis missions, it will also provide water and air for astronauts. Artemis I is an uncrewed mission that is being used to demonstrate and test the Orion spacecraft’s capabilities. It also affords mission control the opportunity to get used to flying Orion and operating the European Service Module.

ESA’s Philippe Deloo explains “The European Service Module is operating more fuel-efficiently than the Artemis mission designers had foreseen, and it produces more electrical power while consuming less – many things have impressed us on the module’s performance so far.” “Mission control is enjoying pushing Orion and the European Service Module to their limits,” continues Philippe, “the years of planning, designing, and building to the highest specifications are paying off, the European Service Module is performing better than we could have ever expected and we have lots of data to analyze and learn from, to ensure we will be taking astronauts to the Moon in the safest and most efficient way possible.” As the first European Service Module has been earning its wings flying around the Moon, the second module is already almost complete – its solar wings are folded and packed in storage to be attached to the second Orion spacecraft next year. The second Artemis mission will have astronauts aboard and fly a less intensive route around the Moon and back. The third European Service Module – that will take astronauts to a Moon landing – is in production at the Airbus integration hall in Bremen, Germany, alongside the fourth European Service Module that will power the first ESA astronaut and European lunar Gateway element to lunar orbit. The structure for the fifth European Service Module is set to arrive in Bremen next month. “The demonstrated flight excellence of the European Service Module and Orion so far, together with ESA’s ambitious plans and newly announced astronauts make for an exciting immediate future for European human spaceflight” concludes Philippe. The mission is set to end with a splashdown in the Pacific Ocean on December 11.
