This pompous name is used by NASA and its European counterpart, ESA, to describe the part of the ship that will handle space during the mission.
The unit includes the ship's main engine, an adaptive transport unit called the Orbital Maneuvering System, 24 smaller engines grouped into six pods to provide attitude control, and eight propellers used for orbit corrections.
The hardware comprises all 20,000 components, including four solar array wings and gas and propellant tanks.
Now that this module is in the United States, NASA engineers will begin testing it to make sure everything is working properly. After this stage is complete, the operations for pairing with the crew module will begin. The resulting assembly, scheduled to be completed early next year, will be shipped to Plum Brook Station, Ohio.
There, it will spend 60 days inside the largest vacuum chamber in the world. If all goes well, Orion will return to the Kennedy Space Center for integration with the Space Launch System that will take you into space.
The first flight of Orion, the exploration mission 1 (EM-1), will be an unrolled test that will see the ship travel 280,000 miles from Earth (450,000 km), well after the Moon, on a three-week voyage. .
NASA says that during this flight the Orion "will stay in space longer than any ship for astronauts without landing at a space station and returning home faster and hotter than ever."
After EM-1, it will be the exploration mission 2 (EM-2), which will see a manned flight arrive in orbit, make a highly elliptical demonstration around the world and, driven by the European service module, go to the moon , without landing there. The mission must last at least eight days.
The European service module is the result of a collaboration between several large companies from ten European states, including ESA's longtime partner and Airbus contractor, while the Orion crew module was built by Lockheed Martin.
