British company Space Forge is trying something no one has done before: building a factory in orbit to make materials for next-generation semiconductors and bring them back to Earth. And this isn’t science fiction anymore in late 2025, its first orbital test vehicle successfully generated the extreme conditions needed for semiconductor production.
The company calls its system ForgeStar-1, a microwave-oven-sized satellite launched into low Earth orbit in June 2025 aboard a SpaceX rocket. By December, that little spacecraft had fired up its miniature furnace and produced plasma at around 1,000°C (1,832°F) an essential step for growing the crystal “seeds” that could one day become ultra-efficient chip materials.
Space Forge says forging these materials in space could lead to some dramatic benefits over traditional Earth-bound manufacturing. In microgravity, atoms can assemble in much more orderly ways and without convection currents or sedimentation that plague crystal growth on Earth. That combination plus the near-perfect vacuum of space — can reduce defects and contamination to levels impossible to achieve in a terrestrial fab.
Early estimates from Space Forge and industry observers suggest that semiconductors made in space might be up to 60 % more energy efficient than those made on Earth, with some proponents including company leadership and independent commentators claiming materials could be “hundreds to thousands of times purer” than terrestrial equivalents.
Joshua Western, Space Forge’s CEO and co-founder, puts it plainly: “Generating plasma on orbit…proves that the essential environment for advanced crystal growth can be achieved on a dedicated, commercial satellite opening the door to a completely new manufacturing frontier.”
But let’s step back and unpack that. Why does anyone think making chips in space is worth the trouble?
On Earth, making advanced semiconductors demands enormous facilities often costing $5 billion or more and uses massive amounts of water, energy, and ultra-clean environments to control contamination and gravity-driven effects. In orbit, by contrast, the natural environment already provides a high-quality vacuum and microgravity, potentially trimming some of those burdens. That’s why researchers have studied crystal growth in microgravity ever since early experiments on NASA’s Wake Shield Facility and the International Space Station.
Of course, this approach has critics. Space Forge’s first satellite isn’t actually producing finished chips, and some industry watchers say calling it a “factory” is premature. One online commentator noted that the real leap scaling up production and safely returning materials to Earth is still years, possibly decades, away.
Even Space Forge itself acknowledges the hurdles. Western has repeatedly pointed to regulatory snags like the difficulty of getting launch approvals and figuring out how to tax materials that are made in space but returned to Earth as among the biggest challenges the company has faced.
Still, the potential market dynamics are huge. According to market analysts cited by Space Forge, the global semiconductor industry grew by about 22 % in 2025 and is on track to reach roughly $1 trillion in annual sales by 2027, driven largely by demand from AI data centers, 5G infrastructure, and advanced computing sectors.
Space Forge’s long-term goal is ambitious. The company plans to launch a larger follow-on satellite ForgeStar-2 equipped with a heat shield designed to survive re-entry so that it can actually bring finished materials back to Earth, where they can be further processed and turned into chips. According to one LinkedIn post from Space Forge, each future orbital factory could produce enough raw material for 10 million high-performance semiconductors within weeks once active.
This idea is part of a broader trend in space technology. Other companies, like the U.S. startup Varda Space Industries, are exploring in-orbit manufacturing of pharmaceuticals and other high-value materials. Meanwhile, firms like Besxar, backed by SpaceX partnerships, are experimenting with orbital “fabships” that could test chipmaking processes in near-space vacuum conditions.
So while we’re still far from seeing your next smartphone filled with chips literally made in orbit, the steps being taken today by Space Forge and others could one day make that possible. Western himself frames the ambition in simple terms: “My hope is that in 10 years’ time, what I do is boring… when someone says their phone or laptop was made using a space-made chip, and it doesn’t excite them, then I know we’ve succeeded.”
It’s a long road, but the tiny fires ignited on ForgeStar-1 are showing that the idea exotic as it sounds might not be as far off as it once seemed.
