Interlune

HQ Seattle, WashingtonFounded 202011-50 employees

Interlune is pioneering the harvesting of natural resources from space, starting with helium-3 from the Moon, aiming to revolutionize industries such as quantum computing, national security, clean energy, and medical imaging. Founded by space industry veterans, including former Blue Origin executives and Apollo 17 astronaut Harrison H. Schmitt, the company has developed innovative, energy-efficient technology that will responsibly and sustainably harvest the helium-3 from the lunar regolith and return it to Earth for sale to commercial and government customers. In time, Interlune will harvest other resources such as industrial metals, rare Earth elements, and water to support a long-term presence on the Moon and a robust in-space economy. With successful funding rounds totaling $18 million and grants from the U.S. Department of Energy and NASA, Interlune is poised to lead the commercialization of space resources, unlocking unprecedented growth and innovation for the betterment of Earth and humankind.
