Lockheed Martin has completed the first run of the Orion capsule for the Artemis 2 mission – the first Orion capsule to be tasked with carrying humans.
As work continues on that capsule, Lockheed Martin – the main contractor for the Orion spacecraft – has provided updates to the other three capsules, and three European service units, currently in various stages of their respective flows for Artemis 1, 2 and 3 missions.
Orion Boost Artemis 2
The significant achievement of all spacecraft is the first power supply – a milestone Orion capsule for Artemis 2 Achieved in the week of May 23rd.
“We just got it working for the first time, and it’s a huge achievement for us because we’ve been working on it now for several years,” said Jules Schneider, director of Orion Assembly, Testing, and Launch Operations at Lockheed Martin. A position responsible for overseeing the assembly and testing of the spacecraft up to the point at which it is delivered to NASA.
Schneider himself has been with the Orion program since its inception and was part of the team that drafted the initial proposal for the spacecraft when it was part of the now-cancelled Constellation program.
“We finally got enough avionics, electronics, all the wiring and everything else needed on the plane and integrated so we could get it up and running for the first time, load the flight software, etc.” Schneider related.
Certain functional checks on the nascent state of the capsule are currently being performed, with Schneider noting that there is still a significant amount of assembly and integration work for this capsule even though it is far in the overall construction lifecycle.
Meanwhile, this Orion’s European Service Module (ESM) is also at the Kennedy Space Center Preparations are underway for integrated testing and flight.
“European service modele is integrated into the Crew Module Adapter, which is part of the Service Module [Lockheed Martin] Builds and tests,” Schneider noted. “This is all perfectly integrated. So if you’re going out to the store floor, you’ll see a service unit that’s almost completely assembled and still has some work to do and some unit level testing.”
He continued, “The stage we’re at now for Artemis 2 is that we’re entering a more central phase of testing versus the assembly or build phase. We still have some environmental testing to do, we have a thermal cycle.” [tests] At unit levels for both the crew unit and the service unit. We have live field acoustics that need to be done at the unit level for both the crew unit and the service unit.”
Then, the next step will be to test the vacuum on the Orion integrated array (which includes the service module) before handing the system over to NASA for stacking and flight. Space Launch System (SLS) rocket.
This delivery to NASA is currently targeted for the fourth quarter of 2023.
Orion for Artemis 1
Meanwhile, Artemis 1’s older brother Orion has so far passed his part of the expedition’s wet clothes rehearsal with flying colors.
“My understanding is that the Orion for Artemis 1 did very well during the floor treatment test and wet clothes rehearsal test,” Schneider noted. “And we support all of that because Orion is up and running while all the systems are being monitored. Orion has been doing really well.”
after, after Lockheed Martin Artemis 1 Orion delivered to NASAthe US space agency moved the assembly to a hazardous processing facility where it was refueled for the mission and its inert launch thwart system was installed.
The completed Orion stack was then moved to the Vehicle Assembly Building (VAB) and hoisted over the SLS at High Bay 3 of the building. Its stacking marked the first time a complete SLS missile had been assembled and tested as a fully integrated system.
This mighty lacks a few things – in particular The Environmental Control and Life Support System (ECLSS) is fully functional – This will be required when streaming Orion in the future for Artemis 2 and beyond.

Schneider noted: “In Artemis 1, we do not move in all but part of the ECLSS subsystems.” “The subsystems that are involved in keeping humans alive or communicating with humans, are not flown aboard the Artemis 1, so you won’t get any data back until the Artemis 2 flies.”
“So even Artemis 2 will be a development journey because this is the first time that a fully equipped Orion spacecraft has flown.”
Along the same lines, Orion’s Launch Abort System (LAS), built by Northrop Grumman, is inert for Artemis 1. Since there is no crew for the mission, and since only some Artemis 1 Orion avionics assemblies and seats are planned to be reused (with total vehicle re-flight not planned), there is no compelling need for an active abort system on first flight as Orion recovery is in A launch failure will not – in practice – speed up the timetable for return to flight.
Therefore, the LAS will be inactive for Artemis 1 but fully active for Artemis 2 and later.
To this, Schneider noted, “We have already tested the launch abort system, both from A view of the foil pad The viewpoint of abortion ascension. So we’ve already verified, if you will, that the Launch Abort system is working.”
Orion for Artemis 3 … the first to be reused
While no reuse of Orions for Artemis 1 and 2 is planned, This will change with Orion currently being built for Artemis 3 – the planned mission to return humans to the lunar surface for the first time in more than 50 years after the departure of Apollo 17 on December 14, 1972..
After bringing the Artemis 3 crew back to Earth, the current plan is to take the capsule, refurbish it, and fly it back on Artemis 6.
But before that, the capsule must be fully built, tested and prepared for its first flight.
Crew unit pressure shell [has been] Schneider said. “It’s going well.”
All basic structure assemblies are complete in this capsule as well as proof tests on its structure.
Teams are currently installing hundreds of brackets and various secondary structure elements that will hold cables, avionics boxes, systems, etc. These are known as secondary structures.
“That’s the point we’re at right now,” Schneider noted. “And then once that’s completed this summer, we’ll go into the cleanroom and start integrating the propulsion systems and ECLSS.”
“We’ll be in the cleanroom for months doing that. And then, when we get out, we start doing the electrical integration. Same lifecycle as Artemis 2, but Artemis 3, I say, we’re still in the early stages of it.”
The crew module adapter for this flight is also well underway.
“We’re building it from the ground up. It’s a mechanically composite structure,” Schneider added. “And that’s what we’re working on now, the structural part of it.”
“And it has a similar life cycle to the new unit in that once we do the structural integration, we do the propulsion system and ECLSS integration and then we move on to the electrical integration. So it’s not as complicated as the crew model.”
Work is being done on the Crew Module adapter in parallel with the construction of the European Service Module for this flight. ESM-3 is currently in Bremen, Germany, where it is undergoing construction and propulsion prior to shipment to the Kennedy Space Center next year.
“Once we have the ESU, we will merge the two.”
European service units and . are funded Built by the European Space Agency (ESA) In a barter agreement with NASA for crew time International Space Station (Service units for Artemis 1, 2, 3 and 6) as well as for time and ESA’s contribution to Moon Gate (Service units for Artemis 4 and 5).
Orion capsules from Artemis 4 and 5 – the latest Orion designs currently planned
Overall, Orion for Artemis 4 is currently undergoing pressure vessel construction at the Michoud Assembly facility in New Orleans, Louisiana.
Expected to be delivered to Kennedy Space Center In February 2023 for the construction of primary and secondary buildings.
It will then follow the Artemis 5 Orion’s pressure vessel.
Under the current contract with NASA, Lockheed Martin is responsible for building and delivering Orions through Artemis 5.
Beginning with Artemis 6, the plan is to reuse the three fully functional Orions for future Artemis crew missions.
