The concept of mining on the Moon is edging closer to reality, moving beyond the realm of science fiction. A pioneering step has been taken by the US-based space technology startup, Interlune, which has introduced its first-ever prototype aimed at mining Helium-3, a vital resource found on the lunar surface. ‘Operating machinery on the Moon demands unprecedented levels of reliability and performance,’ stated Rob Meyerson, the co-founder and CEO of Interlune, during a press briefing on May 7.
The innovative machine developed by the company is designed to process 100 metric tons per hour—equivalent to approximately 110 tons of lunar regolith—to extract the elusive isotope Helium-3. This isotope, rare on Earth, holds the promise of being a potential fuel source for future fusion reactors. Gary Lai, the co-founder and CTO of Interlune, underscores that such a high-capacity excavation process, capable of efficiently extracting large quantities of helium-3, has never been attempted before.
The prototype is the result of collaboration with Vermeer, a company boasting 70 years of expertise in crafting agricultural and industrial machinery. Following the success of tests conducted on a smaller scale model last year, Interlune proceeded to construct a full-size prototype. Lai expressed satisfaction with the testing outcomes thus far and conveyed readiness to progress to the subsequent development phase.
This machine marks the initial phase in Interlune’s comprehensive four-step system for processing extraterrestrial resources: excavation, separation, extraction, and purification. By refining each of these processes, the company intends to make lunar resources viable for transportation to Earth.
Helium-3 has long intrigued nations like the US, China, and Japan. It is theorized that this isotope could power fusion reactors, potentially generating energy without producing radioactive waste, thereby revolutionizing the energy sector. Achieving this, however, requires an economical method to transport Helium-3 from the Moon to Earth. Although these aspirations are becoming increasingly tangible, the prospect of lunar mining, much like fusion energy, remains a vision for the future.
