A small but ambitious technology company based in Cardiff, Wales, has reached a significant milestone in its effort to move semiconductor manufacturing beyond Earth. Space Forge, a startup focused on producing advanced materials in orbit, has successfully powered on a high-temperature furnace aboard one of its satellites, achieving operating temperatures of around 1,000 degrees Celsius while in space.
The test, first reported by the BBC, represents a crucial validation step for the company’s long-term plan to manufacture semiconductor components in microgravity. The furnace—compact and comparable in size to a household microwave—is a central piece of equipment needed to process semiconductor materials. Successfully operating it in orbit demonstrates that complex, heat-intensive industrial processes can function reliably outside Earth’s atmosphere.
“This is so important because it’s one of the core ingredients that we need for our in-space manufacturing process,” Space Forge Payload Operations Lead Veronica Vera told the BBC. “So being able to demonstrate this is amazing.”
For a concept that until recently existed largely in theory, the successful test provides tangible proof that orbital manufacturing systems can withstand the harsh conditions of space.
Why the Semiconductor Industry Is Looking Beyond Earth
Semiconductor production on Earth is among the most resource-demanding manufacturing processes in the world. Modern chip fabrication facilities require enormous amounts of electricity, highly purified water, and tightly controlled clean-room environments. Even with these measures, microscopic defects can form during the creation of semiconductor crystals, reducing efficiency and performance.
Space Forge believes that the environment of space offers natural advantages that could help overcome these limitations. In microgravity, atoms are less affected by convection and sedimentation, allowing them to arrange themselves more evenly during crystal growth. At the same time, the vacuum of space removes the risk of airborne contamination, a persistent challenge for Earth-based fabs.
By reducing these sources of imperfection, space-based manufacturing could yield cleaner, more uniform semiconductor wafers—an outcome that could significantly improve performance across a range of technologies.
Claims of Exceptional Purity Gains
According to Space Forge, the potential improvements are not incremental. The company claims that semiconductors produced in orbit could reach levels of purity far beyond what is currently achievable on Earth.
“The work that we’re doing now is allowing us to create semiconductors up to 4,000 times purer in space than we can currently make here today,” Space Forge CEO Josh Western told the BBC.
Western said such components could play a critical role in technologies that demand extreme reliability and efficiency. These include 5G telecommunications infrastructure, electric vehicle charging systems, and modern aircraft, where even small gains in efficiency can have meaningful impacts on energy use and performance.
While these claims will require further validation as production scales up, they point to why governments and private investors are paying close attention to orbital manufacturing experiments.
From Launch to Operation: A Slow and Complex Process
Space Forge’s recent success followed a long and technically challenging journey. The company launched its first satellite in June 2025 as part of SpaceX’s Transporter-14 rideshare mission. Although the satellite reached orbit without issue, activating its onboard manufacturing systems took several additional months.
Operating precision industrial equipment remotely in space presents unique difficulties. Power systems, thermal controls, and communications links must all work flawlessly, often without the possibility of real-time intervention. Even small deviations can delay operations or force redesigns.
The extended timeline highlights the complexity of translating laboratory concepts into functioning orbital systems, where repairs and adjustments are far more difficult than on Earth.
Ambitions to Scale Up Orbital Production
Encouraged by the successful furnace test, Space Forge is now planning its next phase: a larger orbital manufacturing platform capable of producing as many as 10,000 semiconductor units. Such an expansion would move the company closer to demonstrating that space-based chipmaking can operate at commercially meaningful scales.
However, scaling production introduces new challenges beyond manufacturing itself. One of the most significant hurdles is returning finished products safely to Earth. Any retrieval system must protect delicate semiconductor materials during reentry while meeting strict safety and regulatory standards.
Space Forge has previously suggested that reusable return capsules could be part of the solution, but those systems remain under development.
A Competitive Push Toward Orbital Factories
Space Forge is part of a growing group of companies exploring space as a manufacturing environment. In the United States, startup Besxar has outlined plans to deploy free-flying “Fabships” into orbit using SpaceX Falcon 9 rockets.
The presence of multiple players signals increasing interest in off-world industrial production, driven in part by global semiconductor shortages and rising demand for advanced chips. As semiconductors become more central to economic and national security concerns, alternative manufacturing approaches are attracting serious attention.
Environmental Benefits and Trade-Offs
Supporters of orbital manufacturing argue that shifting some semiconductor production to space could reduce pressure on Earth’s resources. Traditional fabs consume vast quantities of water and energy and generate chemical waste. Producing certain materials in orbit could eventually ease those demands.
At the same time, the environmental cost of rocket launches cannot be ignored. Sending raw materials into orbit and returning finished products would require frequent launches, each contributing to carbon emissions and atmospheric pollution. Increased launch activity also raises concerns about space debris and long-term sustainability.
Any large-scale adoption of orbital manufacturing will need to balance these competing environmental factors.
