Seattle-based Interlune has secured an additional $5 million through a Simple Agreement for Future Equity (SAFE). This follows a previous funding round earlier in 2026, which also raised $5 million. The latest investment round included both existing and new backers.
Founded in 2020, the company focuses on extracting resources from lunar regolith, specifically helium-3. Interlune notes that helium-3 could be valued at over $9 million per 500 grams. Potential applications include medical imaging, quantum computing, and fusion energy.
The company has expanded its business model to include the development of lunar infrastructure and life support systems. In July, Interlune partnered with industrial equipment manufacturer Vermeer to create construction machinery suitable for lunar operations, potentially supporting NASA initiatives.
Interlune plans to launch its first payload, a mineral mapping instrument, to the Moon in 2026 via the Griffin-1 lander from Voyager Technologies. Subsequent missions will assess helium-3 deposits and test extraction technologies, with commercial production and Earth delivery targeted for the 2030s.
