In a groundbreaking move for semiconductor innovation, UK-based startup Space Forge has raised $30 million in Series A funding to develop advanced chip materials in space. Based in Cardiff, Wales, the company aims to harness microgravity to produce next-gen semiconductors with fewer defects—crucial for high-efficiency applications in AI, 5G, defense, and quantum computing.
The idea, once considered science fiction, is now gaining real traction. Space Forge’s materials—crafted in the vacuum and weightlessness of orbit—are believed to outperform their Earth-made counterparts. A collaboration with British Telecom (BT) is already in motion to test space-grown crystals that could slash power consumption in 5G towers.
CEO Joshua Western explained that the company builds upon 50 years of research into in-space manufacturing. The goal is clear: produce ultra-pure wafer materials that serve as the “invisible backbone” of tomorrow’s computing power. Western emphasized that orbital production allows for near-perfect crystal formation, enhancing conductivity and reliability—ideal for cutting-edge sectors like defense and supercomputing.
Backing the venture is the NATO Innovation Fund, which led the Series A, joined by heavyweight defense player Northrop Grumman. Their support reflects growing Western interest in reducing reliance on foreign semiconductor supply chains, especially amid global tensions over Taiwan’s chip dominance.
But Space Forge doesn’t plan to launch its own rockets. Instead, the startup is focusing on perfecting return technologies—a crucial step in making orbital manufacturing commercially viable. Its flagship return system, Pridwen, is a high-tech umbrella-shaped heat shield designed to float materials safely back to Earth. Another solution, Fielder, is a net designed to catch descending satellites over water.
The startup is also building strategic infrastructure across Europe. It recently launched a new hub in Portugal’s Azores, optimizing satellite returns and boosting European confidence in orbital manufacturing. Despite Brexit, Space Forge continues receiving strong backing from both the UK Space Agency and the European Space Agency.
Space Forge markets itself as a carbon-negative technology, highlighting the environmental benefits of more energy-efficient chip production. But scaling adoption and proving its sustainability impact remain key hurdles.
Its first mission in 2023, involving the ForgeStar-0 satellite, was lost due to a Virgin Orbit rocket failure. Now, with fresh funding, Space Forge is prepping for the launch of ForgeStar-1, scheduled for later this year. The mission, cheekily titled “The Forge Awakens,” is a Star Wars nod signaling the company’s next bold chapter in high-tech space manufacturing.
