The Artemis II mission is a big deal on its own – the first time astronauts will travel around the Moon since Apollo. But what doesn’t get talked about as much is how much of that mission depends on manufacturing happening far from the launch site, in places like Denver, Boulder, and Colorado Springs.
No headlines, no countdown clocks – just a lot of highly technical work done right, over and over again.
It starts on the shop floor
Before anything ever leaves the ground, it starts as raw material. Aluminum blocks, composite layers, wiring, specialty metals. From there, it moves through machining, assembly, testing – sometimes multiple times.
For Artemis II, Colorado manufacturers have been involved in building and supporting things like:
- Structural components for crew systems
- Avionics hardware and electrical assemblies
- Thermal protection materials and supporting parts
- Navigation and control system components
None of these are forgiving. If something fails in space, there’s no fixing it.
The kind of manufacturing this requires
This isn’t standard production work. Aerospace at this level demands a different level of control and consistency.
A lot of the work tied to Artemis II relies on:
- Precision CNC machining – holding extremely tight tolerances on critical parts
- Composite manufacturing – creating lightweight but strong components
- Additive manufacturing – reducing weight and simplifying complex designs
- Electronics assembly – building systems that can handle vibration, heat, and radiation
- Cleanroom assembly – keeping sensitive components free from contamination
It’s detailed, process-driven work. The kind where documentation matters just as much as the part itself.
Contracts behind the scenes
The structure of the work is layered. Most Colorado manufacturers aren’t working directly on a single “Artemis II contract.” Instead, they’re part of a broader supply chain.
That usually looks like:
- Prime contracts managing full systems and mission integration
- Subcontracts for specific components or assemblies
- Tiered suppliers supporting with materials, machining, and specialized processes
A machine shop in Colorado might be producing a component that ends up in a larger assembly, which then becomes part of a system that ultimately flies on the mission. Everyone is working to the same standards, even if they’re several steps removed from the final build.
The small parts matter just as much
Some of the most important work coming out of Colorado shops are the parts no one will ever see.
Fasteners, brackets, connectors, housings – all built to exact specs, often using materials like titanium or high-performance alloys. These parts go through strict inspection and testing, including things like non-destructive testing and full traceability back to raw material batches.
It’s not flashy, but it’s critical.
Why Colorado plays such a big role
Colorado has built a strong aerospace manufacturing base over time. There’s a mix of experienced machinists, engineers, and technicians who understand what “flight-ready” actually means. Add in access to research institutions and a steady pipeline of skilled workers, and it makes sense why so much work for missions like Artemis II runs through here.
It’s also a place where smaller manufacturers can plug into larger programs. You don’t have to be a massive company to contribute – you just have to be able to meet the standards.
The takeaway
When Artemis II launches, most people will be focused on the rocket, the crew, and the mission itself. Fair enough.
But a big part of what makes that launch possible was built piece by piece, long before liftoff, in manufacturing facilities across Colorado.
No spotlight – just work that has to be right the first time.
