Orion prime contractor Lockheed Martin has the spacecraft for NASA’s Artemis III and IV lunar touchdown missions in manufacturing alongside the Artemis II automobile that’s going into ultimate meeting on the Kennedy Area Heart (KSC) in Florida. Simultaneous meeting and check of three Orions is changing into the norm, because the Orion program works in direction of its purpose of delivering one spacecraft yearly for eventual, annual Artemis missions.
Following the Artemis II lunar flyby check flight, the Artemis III Orion would be the first to show full rendezvous and docking operations when it meets up with SpaceX’s Starship lunar lander in cislunar area in the course of the mission. NASA nonetheless aspires to fly Artemis III as quickly as December 2025, and the area company continues to emphasize supply dates for not simply Artemis III, but additionally for the Artemis IV Orion to observe as shut behind as doable.
Artemis III Orion first construct below manufacturing and operations contract
Lockheed Martin builds the crew module (CM) and crew module adapter (CMA) parts of NASA’s Orion spacecraft within the Neil Armstrong Operations and Checkout (O&C) Constructing at KSC; the economic operations zone (IOZ) within the constructing can also be the place ultimate meeting of the CM and CMA with the European Service Module (ESM) happens. Whereas that ultimate meeting, check, and checkout of the Orion for Artemis II is happening at one finish of the IOZ ground, {hardware} for the following two spacecraft are additionally being assembled concurrently.
The Orion program is aiming to have the spacecraft for Artemis III prepared for supply a few 12 months after they flip the Artemis II Orion over to Exploration Floor Methods (EGS) subsequent spring. “[For] Artemis III, there are a number of issues driving [production],” Debbie Korth, Orion Deputy Program Supervisor for NASA, stated throughout a Aug. 8 media occasion at KSC.
“The docking system is definitely considered one of them [and] we’ve got some ECLSS (environmental management and life assist system) parts coming from considered one of our subs (subcontractors). A number of {hardware} has to get built-in, after which the European Service Module for Artemis III is ready to be delivered by the top of this 12 months.”

At a really excessive stage, meeting begins with the construction of the spacecraft. After the first and secondary construction is assembled, then tubing is welded in a “clear room” space, connecting up plumbing for fluids and propellant. Then wiring harnesses are laid out and related on the within and out of doors of the automobile, adopted by set up of spaceflight gear, and at last testing and checkout.
As seen on the ground of the IOZ in the course of the early August media occasion, the CM and CMA for Artemis III have accomplished structural meeting and are progressing via tube welding because the elements for the tubing are delivered to KSC. As soon as all of the tubing is welded into place, the welds might be proof examined.
“The perfect movement could be [to] have every part right here, get all of it put in, go within the clear room one time, [and then] do the proof and stress [test], however it by no means works out that method,” Korth stated. “What they find yourself doing is as they get parts in, they set up them, after which they’ll go out and in of the clear room.”
“We should not have all of the parts within the manufacturing unit but for Artemis III, there’s nonetheless a number of dozen that they’re ready on. These guys that run the manufacturing ground, they preserve monitor of the hundreds of parts as they’re coming in and resequence issues [and] if we’re ready on one thing, go do one thing else.”
“They’re going to put in issues as they get them and so they transfer the automobile round between the stations, whether or not that’s clear room or the opposite areas,” she defined. “As soon as parts get right here, issues can go actually rapidly, I feel the Lockheed meeting workforce they’re excellent about rescheduling and resequencing and maintaining the automobile shifting.”
The CMA is in the same scenario, it’s ready for a number of extra tubes to come back in for ultimate standalone welding work. “They nonetheless must put some parts in it, they nonetheless must construct it out, however as soon as the ESM arrives right here it’s about three to 4 months after that after they put them collectively,” Douglas Lenhardt, NASA Provide Chain Lead for Orion at KSC, stated.
The Orion spacecraft for the Artemis III lunar touchdown mission would be the first to have full rendezvous, proximity operations, and docking (RPOD) capabilities. The Artemis II crew will manually pilot their spacecraft throughout a proximity operations and dealing with qualities demonstration on the primary day of the mission, however the Artemis III automobile may have absolutely automated RPOD software program and {hardware} to hyperlink up with SpaceX’s Starship HLS lunar lander in cislunar area.

Korth stated that NASA is at present anticipating the docking adapter to be delivered to KSC in January. The docking adapter will connect to the entrance of the crew module and might be jettisoned on the finish of the mission. “It’s jettisoned earlier than re-entry, so we don’t convey it again. It’s packed on prime of the ahead bay cowl.”
Lockheed Martin and NASA are nonetheless evaluating the place within the pre-launch manufacturing movement to put in the docking adapter. “It is among the final issues that goes on and we’re wanting proper now at whether or not or not we will have that put in after we’re within the LASF (Launch Abort System Facility), so type of taking part in with the set up sequence to see the place that’s most advantageous, however that is among the final gadgets that goes on.”
After the spacecraft is delivered to EGS, it’s moved to the Multi-Payload Processing Facility (MPPF) the place commodities like propellant for the spacecraft engines and thrusters and oxygen and water for crew life assist are loaded for flight; the spacecraft is then moved to LASF, the place the Launch Abort System rocket-and-tower meeting is stacked on prime of the crew module. The LASF is the final cease for the spacecraft earlier than it’s positioned on prime of its Area Launch System (SLS) launch automobile within the Automobile Meeting Constructing.
The ESM for Artemis III is a bit of farther alongside in its manufacturing in Germany. “ESM-3 is at present present process ultimate integration steps at our integration facility at Airbus in Bremen, we’re ending the welding for the propulsion half, we’re beginning to do some testing; at this very second we’re doing {the electrical} checkouts,” Kai Bergemann, European Service Module Deputy Programme Supervisor for Airbus, stated on the Aug. 8 media occasion. “We’re nonetheless on-track for supply on the finish of the 12 months.”
The ESM has the principle storage tanks for the multi-week lengthy Orion missions, storing the commodities which are loaded within the MPPF like propellant and oxygen and water. “These [storage tanks] are all put in, we’ve got all of the gear put in, we simply have to finalize some welding on among the tubes on the propulsion facet, however apart from that the {hardware}, the large gadgets, are all built-in,” Bergemann famous.
“Even the massive propellant tanks have been built-in some weeks in the past, which is a significant milestone for us within the progress of that integration, and so now it’s about testing, it’s actually about optimizing the check sequence in an effort to meet the supply date right here.”

Standalone meeting is anticipated to be accomplished by the top of the 12 months, which is when ESM-3 is anticipated to reach in Florida. The 2 parts might be mated to grow to be the service module subsequent 12 months.)
As famous, a number of months after the ESM arrives in Florida, the CMA and ESM must be able to mate collectively to kind the service module (SM) for Artemis III. Proper now, that may be within the spring 2024 timeframe across the identical time that the Artemis II spacecraft is delivered for launch preparations.
Following the mating of the CMA and ESM, the following main milestone for the service module could be preliminary power-on or IPO, which is the beginning of the testing and checkout part for the module. Proper now, Orion tasks each the crew module and the service module to be prepared for his or her preliminary power-up in that spring 2024 timeframe.
Every module will undergo a sequence of standalone thermal and acoustic exams; the nozzle for Orion’s fundamental engine would even be put in on the ESM, together with the Spacecraft Adapter that helps be a part of Orion with SLS.
Following standalone testing and checkout, the schedule has the crew and repair modules able to be mated starting within the fall of 2024. One other spherical of built-in testing, together with a vacuum check within the IOZ, would should be accomplished earlier than the photo voltaic array wings could be connected and the spacecraft delivered to EGS for Artemis III launch preparations.
At present, the Orion program’s manufacturing purpose is to ship the Artemis III spacecraft to EGS within the spring of 2025, a few 12 months after the Artemis II spacecraft supply in late April 2024, which might assist NASA’s aspirational December 2025 date of launching Orion on an SLS rocket to start Artemis III and the primary mission to land astronauts on the Moon in over 50 years.
Orion seems to be to dam purchase of elements to ascertain supply cadence, shut in on annual purpose
The Artemis IV Orion crew module and crew module adapter are additionally taking form within the IOZ subsequent to spacecraft it can observe. Structural meeting remains to be in progress for each parts; the stress vessel on the middle of the crew module was delivered from the Michoud Meeting Facility in New Orleans to KSC in February.
Kaileah Blazek, Mechanical Methods Integration & Check Engineer for Lockheed Martin, stated on the Aug.8 media occasion that the crew module construction had only in the near past accomplished its proof stress check. “We simply completed final week,” she stated.

“We’ve a few week value of check setup and integration, the place we truly join 700 [strain gauge] sensors, after which a few week for the precise check, between performing the check and knowledge evaluation. We do a number of runs; we do a max design stress run after which do the precise full proof stress run.”
Blazek famous that the utmost stress check is brief; the crew module construction is pressurized to 1 and a half instances its most design stress for lower than a minute.
The rest of the secondary construction will now be put in on the crew module, principally brackets. “It’s simply now getting secondary construction,” Korth stated. “I feel the blokes on the ground name it ‘loss of life by bracket’ as a result of it’s simply bracket after bracket after bracket after bracket, it’s someplace fairly early within the movement.”
Structural meeting of the Artemis IV crew module adapter can also be properly underway down the IOZ hallway, with longerons and intermediate frames radially connected to the CMA inside ring.
Each Artemis IV buildings will proceed into the clear room in 2024 to start tube welding, and the Orion program workforce is hoping that the acquisition technique below the Orion Manufacturing and Operations Contract (OPOC) will permit progress to be made in direction of the long-term manufacturing purpose of delivering one spacecraft yearly for eventual Artemis missions to the Moon yearly. On the time the OPOC award was announced in late 2019, the Artemis III, IV, and V automobiles have been ordered as a set, so the parts for Artemis III which are trailing the manufacturing schedule must be delivered with the identical elements for Artemis IV and V.
“Our parts for Artemis III, IV, and V [are] ordered in heaps,” Korth defined. “When Lockheed was placed on contract for Artemis III, IV, and V, they [began] shopping for issues in bulk, so whereas [Artemis] III could also be a problem as we’re ready for parts to come back in and have to remodel schedules, after we get III, we largely get IV and V as properly, as a result of they’re coming in as a set.”
“So, I feel these schedule challenges get a bit of bit simpler going ahead as a result of we’re getting forward of getting that {hardware} into the manufacturing unit, and as soon as it’s there, there’s much more flexibility on the schedule. While you’re ready on one thing, you’re on the mercy of the [component schedule].”

By way of reaching the annual supply purpose sooner or later, Korth additionally famous that “there are issues like ESMs that should be delivered on once-a-year facilities as properly to make that occur,” for the reason that European Service Module contracts are aligned alongside completely different builds.
The onset of the worldwide COVID-19 pandemic shortly after the OPOC award and the following provide chain disruption was a further complication; though the trade and provider base has recovered considerably, these COVID provide chain results are nonetheless being felt. “I feel the availability chain has drastically improved in the previous couple of months, however it’s nonetheless our greatest problem,” Korth stated.
“In a variety of instances [we are buying] very distinctive {hardware} and, you already know, we discuss this ‘strong area financial system’ that’s being energized and developed, [but] there’s solely so many firms that may construct environmental management and life methods {hardware}, or spacesuits or prop methods. Valves is a large factor; you’re restricted by the individuals who can truly construct this type of {hardware} and there’s a variety of demand on them proper now.”
“It’s getting higher, however it’s nonetheless a problem,” she added.
Even with uncertainty concerning the schedule for Artemis III and different elements that may restrict Artemis missions via the 2020s, NASA needs to maintain its choices open and officers throughout the Exploration Methods Improvement Mission Directorate (ESDMD) have pressured to their packages and contractors to proceed working in direction of long-established “want” dates for deliveries. “The message that we’re making an attempt to take ahead is please work to your dedication or your contract dates…till we’ve got to vary that with a contract change,” ESDMD Affiliate Administrator Jim Free stated in a briefing to the NASA Advisory Council in Could.
“Missions are going to proceed to maneuver round and if all we do is transfer missions round everyone goes to get out of sync. We don’t wish to try this anymore; we wish to ship.”
“If we’ve got to place issues in storage, we’ll put issues in storage,” Free added in Could.
“We’ve a variety of direct interplay with [subcontractors], which I feel is absolutely useful, explaining [our schedules],” Korth famous in August. “Some folks assume ‘why do you want it so early, [for] Artemis III we don’t know when it’s going to fly?’”
“However we’re on a cadence of delivering automobiles and we have to get them finished as a result of dragging our workforce alongside doesn’t assist us if we’re ready on {hardware}.”

Equally, to NASA and Lockheed’s manufacturing purpose, the European Area Company and Airbus are working in direction of delivering ESMs on an annual cadence. “ESM-4 is just about one 12 months after ESM-3, so [with ESM-4] we’re in the course of harness integration,” Bergemann stated.
“Usually we begin with the construction, after we obtain the construction we do major/secondary construction integration, bracket integration, which is adopted by harness integration, and the combination of the primary propellant tubes, so that is at present ongoing for ESM-4.”
At present, the Orion program is concentrating on supply of the Artemis IV spacecraft to EGS in early 2026. Proper now NASA schedules put launch of Artemis IV no sooner than September 2028. In assist of that early 2026 supply date, preliminary power-on of the crew module could be in late 2024, with the service module IPO following in early 2025.
That will result in mating of the crew module to the service module in the summertime of 2025, adopted by ultimate testing via the top of 2025 forward of supply to EGS in early 2026.
Orion factoring Artemis I restoration knowledge, experiences into evolving reusability plans
NASA and Lockheed Martin have plans to reuse returning crew modules and crew module {hardware} extensively starting with the Artemis III spacecraft; as this system transitions from improvement right into a manufacturing and operations part, these plans are being refined. “Reuse is unquestionably a piece in progress on the way it’s going to play out,” Korth stated.
“That plan is evolving and a variety of it has to do with [what] we realized off Artemis I after we acquired the spacecraft again, [such as] how lengthy it takes to decontaminate and get that module itself to a degree the place you might truly set up new parts on it, so ripping every part off you can’t reuse.”
She gave an instance: “Issues such as you splashdown within the ocean and saltwater. We discovered on Artemis 1 after they took off the [backshell] panels you see salt crystals in all places, so we’ve acquired to begin speaking about corrosion resistance and what sort of coatings are we going to placed on issues so we will reuse them.”
“You’re simply studying as you go alongside, however [reuse is] undoubtedly a precedence for this system and I feel it’s the proper reply, it’s simply doing the work to allow all that to occur.”

NASA and Lockheed Martin are finding out methods to guard gear that’s soaked in saltwater after splashdown to enhance the reusability of the spacecraft and its parts.)
Along with the electronics that have been faraway from the Artemis I spacecraft as quickly as doable to be refurbished for set up on the Artemis II spacecraft early in 2023, Orion is wanting on the situation of the spacecraft and the opposite gear that got here again from this system’s first mission to the Moon and again, and the way lengthy it can take to refurbish them and switch them round for a subsequent flight.
“We realized extra concerning the timeline to do this, after which we’ve realized extra about if you do take a part out that requires a [subcontractor] to remodel,” Korth defined. “Lockheed has began working these contracts with these subs and what we might have estimated it being six or eight weeks could possibly be six or eight months.”
“And so that you’re possibly I can’t use that merchandise from [Artemis] III to [Artemis] VI, I want to make use of it from III to VII, so then what do I do on [Artemis] VI? The reuse plan is unquestionably evolving as we be taught extra from our suppliers what they’ll do [and] be taught extra about what we will do when it comes to processing the spacecraft right here at Kennedy, [with] the largest factor being cleansing out [propellant].”
“Prop is a giant deal and there’s solely a few services you are able to do that in, and considered one of them just isn’t the O&C proper now,” Korth added. “If we wish to get again into the manufacturing unit we’ve started working that.”
The naming conventions for reuse are additionally evolving with the plans. “We removed the monikers of ‘gentle and heavy’ and we name [it] ‘part and module’ [reuse],” Korth famous.
