The European-built service module that powers the Orion spacecraft on the Artemis 1 mission is nailing its first lunar journey, however a key system to maintain future human crews alive shouldn’t be being examined in the course of the flight.
The Orion capsuleas began the return leg of its groundbreaking journey on Thursday (Dec. 1), is presently not stuffed with respiratory air, European area big Airbus advised House.com. In keeping with Airbus, which constructed Orion’s service modulethe capsule’s life help system will solely be put via its paces in ground-based laboratories earlier than the primary flight with astronauts in 2024.
The European-built Service Module, accountable for propulsion and navigation, is the a part of the spacecraft that maintains liveable circumstances inside Orion’s crew compartment. The service module carries water wanted by the astronauts throughout flight and generates respiratory air by mixing oxygen and nitrogen saved in separate tanks.

Throughout Artemis 1 missionnonetheless, engineers solely check the nitrogen provide system, however fortuitously not both Shaun the Sheepthe plush toy despatched for the mission by the European House Company (ESA), neither three mannequins occupying Orion’s cockpitbear in mind this truth.
“The oxygen and nitrogen supply techniques are very comparable,” Airbus spokesperson Ralph Heinrich advised House.com in an e mail. “We supply nitrogen aboard Artemis 1 and can check the nitrogen supply system in the course of the flight that’s presently underway. Because the oxygen and nitrogen techniques carry the identical elements, the check of the nitrogen distribution system will cowl the oxygen supply by analogy. Moreover, the oxygen system is extensively examined on the bottom.”
For Airbus, the Artemis 1 mission represents a significant victory. The corporate was awarded a contract to develop the service module, a key part of the Orion spacecraft, by ESA, based mostly on their earlier expertise constructing Automated switch cara cargo vessel that used to produce Worldwide House Station between 2008 and 2014. Throughout its lunar missions within the late Nineteen Sixties and early Seventies, NASA constructed all the mandatory expertise in-house in the US and didn’t embody any worldwide companions.
The Artemis 1 service module is the end result of ten years of labor, and the Airbus staff is delighted to see the craft carry out brilliantly. Up to now, the service module has accomplished all of its key duties flawlessly, together with three engine burns, which first helped Orion enter lunar orbit after which exit lunar orbit to return to Earth.
At a post-launch press convention, NASA admitted it detected 13 anomalies in the course of the early part of Orion’s flight, together with erratic readings from the star trackers the area capsule makes use of to navigate.
“Engineers will look at the info getting back from Orion so that each single system, each single part on board the spacecraft could be examined in a method or one other earlier than the subsequent mission,” Sian Cleaver, the undertaking supervisor for the European Service Module at Airbus advised House.com in an interview. “Up to now so good. In fact there will likely be issues that may be improved or modified. There have been a number of issues that did not work precisely as deliberate, however none of them had been main issues.”
Airbus engineers obtain a stream of knowledge from the spacecraft together with “stress, temperature, valve place knowledge and currents and voltages” to observe its well being, Airbus wrote in an e mail.
“We take a look at all knowledge all through the mission, and particularly throughout main occasions, equivalent to essential engine firings,” Airbus wrote. “[We] make sure that the system is used throughout the anticipated and certified space. Knowledge can also be repeatedly saved to allow post-flight evaluation and preparation for the subsequent Artemis mission.”
Airbus has already delivered the subsequent service module to NASA for testing and pairing with the crew compartment for the Artemis 2 mission, which is able to take people to orbit the moon for the primary time for the reason that final Apollo flight in 1972. That mission is predicted to launch no sooner than 2024, if all goes properly based on plan. The corporate has additionally almost accomplished meeting of the third service module, which is able to energy the Artemis 3 mission that’s anticipated to land on the moon no sooner than 2025.
The legs of the fourth service module have additionally been assembled and plans are in place to start work on the fifth mannequin later this month. These service modules will cowl Artemis missions 4 and 5, that are anticipated to raise off to the Moon in direction of the top of this decade. At the moment, the Lunar Gateway area station will likely be assembled in orbit across the Moon, ushering in a brand new period of standard human visits to Earth’s companion.
“It actually appears like a little bit of a manufacturing line happening now at our facility,” Cleaver stated. “It is actually thrilling. This system is actually, actually shifting now. We have now a plan for the subsequent 10 years, and there are additionally clear messages from NASA and ESA that the moon is simply step one and that the expertise will likely be used to finally go to Mars.”
Airbus is beneath contract to construct service module quantity six and is presently negotiating three extra. The service modules are single-use solely and can detach from the crew capsule previous to entry Earth’s ambiance throughout its return.
The Artemis 1 mission lifted off from NASA’s Kennedy House Middle in Florida on November 16. The mission was a debut not just for Orion, but in addition for the House Launch System megarocket that lifted it into area. Throughout the mission, Orion handed solely 80 miles (130 kilometers) above the lunar floor, additionally breaking a document for the best distance from Earth ever achieved by a human-class spacecraft. By getting so far as 270,000 miles (435,000 km) from the planet, Orion surpassed the earlier most set by the Apollo 13 mission. Nevertheless, that mission solely acquired so far as a part of a rescue operation designed to carry it dwelling after an explosion on board crippled the spacecraft.
