Discover how Artemis II Hardware Built In Europe powers NASAโs Artemis II mission, providing propulsion, life support, and energy for humanityโs first crewed journey beyond the Moon in over 50 years.

Imagine this: four astronauts are about to climb aboard a spacecraft, blast off from Florida, and swing around the Moon in a journey no humans have taken in over half a century. The rocket is American. The crew module is American. But the beating heart that will push them there and keep them alive? Artemis II Hardware Built In Europe โ and itโs ready to fly right now.
As Artemis II sits on the launch pad with liftoff just days away, the spotlight is shining on something many people havenโt heard about yet: the European Service Module, or ESM-2. This isnโt just a support piece. Itโs the powerhouse that will propel Orion through deep space, supply the crew with air and water, generate their electricity, and bring them safely home. Without it, none of this happens.
So who actually built this remarkable piece of hardware? And how exactly will its engines power one of the most exciting missions in modern spaceflight? Letโs take a closer look.
The European Team Behind Artemis II Hardware Built In Europe
The European Space Agency (ESA) teamed up with Airbus Defence and Space as the prime contractor to design and build the service module in Bremen, Germany. More than 20 companies across ten European countries poured their expertise into it โ from structural work in Italy to solar arrays and electronics from Switzerland, plus contributions from France, Belgium, the Netherlands, and beyond.
This wasnโt a quick job. Development started years ago, with the structure taking shape in 2017 and full integration happening step by step in clean rooms across the continent. Airbus led the effort, turning thousands of parts โ cables stretching kilometres, propellant tanks, thrusters, and those massive solar wings โ into a single, reliable spacecraft โengine room.โ
For the first time ever, NASA trusted a non-American partner to deliver a critical, life-sustaining component for a crewed mission. Thatโs huge. The first ESM flew successfully on the uncrewed Artemis I test flight in 2022, proving the design works beautifully. Now ESM-2 is the upgraded, crew-ready version waiting for Artemis II.
Meet the Powerhouse (Artemis II Hardware Built In Europe) That Will Drive Orion to the Moon
Picture a cylinder about four metres tall and wide, weighing roughly 13.5 tonnes at launch. Thatโs the ESM. It sits directly beneath the crew capsule and does almost everything except carry the astronauts themselves.
Artemis II Hardware Built In Europeย job list is impressive:
- Propulsion โ the main way Orion changes course and speeds up.
- Power generation โ keeping lights on, computers running, and systems alive.
- Life support โ providing drinking water and breathable oxygen for the four-person crew.
- Thermal control โ making sure the spacecraft doesnโt freeze or overheat in the extreme temperatures of space.
The real star of the show, though, is the propulsion system. The ESM packs 33 engines and thrusters in total โ a mix of sizes for different jobs.
At the centre is one big main engine (a refurbished Aerojet AJ10 that once flew on Space Shuttle missions). It delivers about 26.6 kilonewtons of thrust โ enough to deliver the critical โtrans-lunar injectionโ burn that flings the spacecraft out of Earth orbit and toward the Moon. Eight smaller auxiliary thrusters (each around 490 newtons) provide backup thrust and help with bigger manoeuvres. Then there are 24 even tinier reaction control thrusters for fine steering and keeping the spacecraft perfectly pointed.
All of this runs on more than eight tonnes of propellant stored in four large tanks. During the roughly 10-day mission, the crew will rely on these engines for several key moments: escaping Earthโs gravity, adjusting their path, flying about 7,500 kilometres beyond the far side of the Moon, and then lining up for the high-speed return to Earth.
Meanwhile, four giant solar array wings โ each stretching seven metres long once unfolded โ will soak up sunlight and generate around 11 kilowatts of electricity. Thatโs plenty to run the entire spacecraft and recharge the systems that keep the astronauts comfortable.
Engineers have built in plenty of redundancy too. Key electronics sit on opposite sides of the module, and the outer skin is wrapped in protective Kevlar to shrug off tiny space debris. Every detail was designed so that if one thing hiccups, another can step in.
Why This Matters Right Now: Artemis II Hardware Built In Europe
Artemis II isnโt just another test flight. Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch from NASA, and Jeremy Hansen from the Canadian Space Agency will be the first humans to leave low Earth orbit since Apollo 17 in 1972. Theyโll fly farther from our planet than anyone alive today has ever gone.
Every time they fire those European-built engines, theyโll be proving that this international partnership actually works. The module will handle the heavy lifting โ literally โ while the crew focuses on testing systems, taking photos, and preparing the way for future landings.
And hereโs the best part: this isnโt a one-off. ESA and Airbus have already signed contracts for several more service modules. The same European hardware will power Artemis III (the first crewed landing) and the missions that follow. Europe isnโt just helping โ itโs becoming an essential partner in humanityโs return to the Moon.

The Bigger Picture: Artemis II Hardware Built In Europe
We often think of space exploration as a single-country achievement, but Artemis shows something more inspiring: when nations work together, we go farther and faster. The European Service Module is living proof that brilliant engineering from Bremen, Turin, Zurich and beyond can help carry humans to new horizons.
As the countdown clocks tick down in Florida, engineers across Europe are watching with pride. Their hardware โ built with care, tested rigorously, and handed over to NASA โ is about to carry four brave astronauts on an unforgettable voyage.
Weโre not just going back to the Moon. Weโre doing it as a global team, with European muscle providing the push.
The next chapter of lunar exploration starts any day now. And when Orion lights up the sky, remember: part of that fire comes from across the Atlantic, from a continent that decided to help write the next great page in space history.
What an incredible time to be alive and watching the stars.
