UK startup Space Forge first successfully ran a furnace in orbit, making ultra-pure materials in space.
In December 2025, UK startup Space Forge successfully operated a furnace in low Earth orbit aboard its ForgeStar-1 satellite, reaching 1,000°C and generating visible plasma—marking the first commercial, uncrewed demonstration of in-space plasma generation.
The test proved key capabilities for automated, remote manufacturing in microgravity, with potential to produce ultra-pure semiconductor materials up to 4,000 times cleaner than Earth-made counterparts.
The company is developing a heat shield named Pridwen to return materials safely, aiming to scale production and integrate space-grown materials into global supply chains.
La startup británica Space Forge fue la primera en ejecutar con éxito un horno en órbita, produciendo materiales ultrapuros en el espacio.
