For decades, we have thought of space as a destination: a place to deploy satellites, astronauts, and scientific instruments. A new generation of startups is attempting to flip the paradigm and treat orbit as an industrial environment, leveraging physical conditions that are difficult or expensive to replicate on Earth. Besxar, founded by ex-OpenAI Ashley Pilipiszyn, aims to apply this concept to one of the most strategic sectors of the global economy: semiconductors.
The startup is working with SpaceX on a series of experiments on Falcon 9 boosters. The goal is not to immediately manufacture a complete processor in orbit, but to progressively develop processes for producing wafers and advanced materials by leveraging the natural vacuum of space.
Why take a factory beyond the atmosphere
Semiconductor manufacturing requires extremely controlled environments. Ultra-thin material deposition, contamination, and particulates can dictate the quality of the final product. On Earth, achieving high vacuum and cleanroom standards demands expensive facilities and substantial energy; in orbit, however, vacuum is an ambient characteristic.
Besxar claims that the first samples exposed to flight conditions showed particularly low levels of particulate contamination compared to terrestrial control wafers. It is a preliminary finding, not proof that an orbital fab is economically competitive, but sufficient to justify more complex experiments.
Falcon 9 becomes a reusable laboratory
The operational insight is to use the Falcon 9 booster—a vehicle that flies and returns at what is now an industrial cadence—as an experimental platform. Instead of waiting for a dedicated mission to the International Space Station, Besxar can iterate more rapidly: first wafer exposure, then heating, followed by the deposition of a single material and, subsequently, multiple materials.
The startup plans around a dozen experimental flights. If it succeeds in qualifying the processes, the next ambition is to move to vehicles offering far more volume, such as Starship, turning what is currently a rocket-mounted experiment into genuine production infrastructure.
Not all chips need space
The economic factor is critical. Launching hardware into orbit and returning products to Earth costs money, introduces risks, and complicates the supply chain. For this reason, a space factory would make no sense for low-cost components produced by the billions. Instead, Besxar is targeting high-value materials and wafers destined for advanced semiconductors, including power components used in data centers, robotics, and electric vehicles.
The right question, therefore, is not whether space will replace Taiwan, Korea, or Arizona in chip manufacturing. It is whether certain ultra-high-value processes can benefit enough from orbital conditions to offset logistics costs.
Microgravity has already become an experimental market
Pharmaceuticals, crystals, optical fibers, and advanced materials have been the subject of microgravity experiments for years. Mitigating convection and sedimentation can yield structural characteristics unobtainable on Earth. The arrival of more frequent launches and commercial reentry capsules is lowering the barrier that once separated scientific research from a viable industrial model.
Besxar is applying this logic to semiconductors, a market where minor gains in purity or material properties can carry immense value. However, it will need to prove not only that the process works, but that it is repeatable and competitive.
The risk is mistaking a good experiment for a viable factory
An industrial production line must deliver yield, volume, uniformity, and predictable timelines. Space adds launch vibration, radiation, thermal constraints, and radically more complex logistics. Furthermore, a substantial portion of chip fabrication involves dozens or hundreds of distinct steps: it would be unrealistic to expect all of them to move off Earth anytime soon.
This is precisely why Besxar's approach is compelling: it starts with a narrow slice of the supply chain. Success does not require building an orbital TSMC; it merely requires identifying one or a handful of processes where the physical advantages of space outweigh the cost of getting there.
After satellites, space aims to become an industrial zone
Lowering the cost of access to orbit has already transformed telecommunications and Earth observation. The next frontier could be utilizing the orbital environment as a manufacturing input. In this scenario, the rocket does not merely deliver the finished product: it becomes part of the factory itself.
It is still too early to tell whether Besxar will succeed in turning experimental wafers into a commercial supply chain. But the question it raises is significant: as traveling to space becomes routine, what products will no longer make economic sense to manufacture on Earth?
