Voyager is building the infrastructure to move in-space semiconductor manufacturing from a successful demonstration to sustained, commercial-scale production.
One of the most strategically important frontiers in low-Earth orbit may also be one of the smallest: the crystals at the heart of every advanced semiconductor. Grown in microgravity, these materials form with fewer defects, greater uniformity and higher yields than anything that can be produced on Earth — and they underpin everything from AI-enabled platforms and advanced sensing to energy-efficient computing and national security infrastructure.
In March 2026, United Semiconductors LLC (USLLC) reserved payload space aboard Starlab, Voyager’s next-generation commercial space station, to move its space-based crystal growth technology from demonstration aboard the International Space Station (ISS) to sustained production in orbit. Behind that reservation is a larger story: the end-to-end infrastructure Voyager has spent decades building to help commercial partners reach orbit — and stay there.
“Advanced materials manufacturing is one of the most strategically important frontiers in low-Earth orbit,” said Marshall Smith, CEO of Starlab Space. “United Semiconductors has already demonstrated the performance advantages of microgravity-grown crystals. Through Starlab’s commercial platform, we will enable the infrastructure needed to move from successful missions to scalable, repeatable production that strengthens domestic supply chains and supports next-generation semiconductor technologies.”
A proven demonstration, now building momentum
USLLC’s initial ISS mission proved that microgravity is a uniquely stable environment for the bulk and thin-film crystal growth of complex semiconductor and semimetal alloys, enabling improved material uniformity, higher yields and better device performance than terrestrial manufacturing allows. That work was completed with strong support from NASA’s In-Space Production Applications program.
Since that first demonstration, USLLC has flown follow-on, next-generation payloads – incorporating lessons learned and iterations built directly on its initial success – and has completed its latest round of on-orbit experiments. Each mission builds on the last, moving the company steadily along the path from proof of concept toward repeatable, commercial-scale output.
Increasingly, the in-space semiconductor industry is finding distinct advantages to manufacturing both inside a pressurized module and outside in the open vacuum of space, and USLLC is pursuing both. By reserving both internal and external payload space on Starlab, USLLC will gain access to the controlled environment suited to certain crystal growth stages, as well as the pure vacuum of open space, which may limit defects and reduce the safety risks of producing certain strategic and critical materials in a closed environment.
Voyager as the mission partner
That flexibility is a natural fit for Voyager, which has a long history of managing payloads that occur both inside the ISS and externally in the vacuum of space. Voyager’s Bishop Airlock — the first and only commercial airlock on the ISS — offers a proven external hosting solution today, and Starlab is designed to carry those same capabilities forward.
Moving from a successful experiment to a production line in orbit requires a partner to handle the complexity of getting a payload safely to space and successfully through its mission, so that customers such as USLLC can stay focused on the development of microgravity-compliant manufacturing technologies beyond the proof- of-concept scientific research.
Drawing on the spaceflight heritage and the know-how behind more than a thousand missions flown for commercial, academic and government customers, Voyager serves as an implementation partner for researchers flying payloads on the ISS today, supporting payload development, integration and on-orbit operations.
Starlab’s commercial payload space is already fully reserved for first-year operations, proving the market for in-space manufacturing and the demand for LEO access is real. For USLLC, the goal was never to become an expert in orbital logistics. The goal is to develop the manufacturing infrastructure and to produce large volumes of higher performance semiconductors than what is possible to make on Earth: stronger supply chains, more capable defense systems and the next generation of computing. Voyager’s job is to handle everything else, so its partners can stay focused on the science that moves industries forward.
