Seattle-based Interlune provided a triple-barreled update today on its progress toward mining helium-3 on the moon and returning that resource to Earth.
The startup joined Vermeer Corp., an industrial equipment manufacturer headquartered in Iowa, to unveil a full-scale prototype of an excavator that’s designed to ingest 100 metric tons of moon dirt in an hour. After the helium-3 is extracted, the machine would drop the rest of the dirt back onto the lunar surface in a continuous motion.
Also today, Interlune announced separate agreements with the U.S. Department of Energy and Maybell Quantum Industries to start supplying lunar helium-3 by 2029.
Helium-3 is an isotope that’s much rarer than the helium-4 that you typically find in lighter-than-air balloons. Helium-3 has a wide range of high-tech applications in fields that include quantum computing, fusion power, medical imaging and weapons detection for national security purposes.
The substance is hard to find on Earth, but it’s more abundant on the moon due to bombardment by solar-wind particles. Interlune aims to take advantage of the potential market by extracting lunar helium-3 and shipping it back to Earth.
