The Future of Space Manufacturing.

SpaceForge’s recent Forgestar One mission proved that a plasma-enhanced chemical vapor deposition (CVD) system can be launched, powered, and operated aboard a low-Earth-orbit satellite. The payload stored gases, ignited a plasma, and began growing a seed wafer—essentially a tiny crystal substrate—demonstrating that the core steps of a fab equipment are feasible in microgravity. This milestone validates decades of research dating back to the 1970s WakeShield experiments and shows that the most complex part of a fab can survive launch, operate autonomously, and return intact for analysis. The advantage of growing crystals in orbit lies in the near-zero gravity and ultra-clean vacuum, which dramatically reduce dislocation density and impurity incorporation.

SpaceForge targets wide-bandgap semiconductors—silicon carbide, gallium nitride, diamond, and aluminum nitride—materials that enable high-voltage power electronics, next-generation RF, and quantum-computing sensors. On Earth, these compounds suffer from low yields because defects limit voltage handling to a few kilovolts; space-grown seeds can push performance toward tens of kilovolts and enable defect-free quantum defect centers. Higher crystal quality translates directly into better efficiency, longer device lifetimes, and new market opportunities for electric vehicles, renewable-energy converters, and space-based sensors.

SpaceForge’s commercial strategy hinges on producing high-value seed wafers in orbit while scaling bulk growth on Earth, a hybrid approach that mitigates launch expense yet leverages space-unique material quality. As launch prices continue to fall—now approaching $2,000 per kilogram—the economics of sending a small, specialized payload become increasingly attractive for niche markets that demand ultra-pure crystals. The company is also exploring in-space device fabrication, such as photovoltaic cells or quantum sensors, which could close the loop by using the same materials for both space and terrestrial applications. If the seed-to-scale model proves profitable, it could catalyze a broader ecosystem of orbital manufacturing, reshaping supply chains for high-performance electronics.
