Helium-3 mining on Moon: A new frontier for science and geopolitics

The article discusses the emerging interest in mining helium-3 from the Moon, highlighting its scientific, technological, and geopolitical significance. Helium-3, a rare, non-radioactive isotope embedded in the lunar regolith by billions of years of solar wind, holds promise for multiple advanced applications. It is crucial for cooling quantum computers to near absolute zero, enhancing medical imaging and security scanners, and potentially serving as a clean fusion fuel that produces minimal radioactive waste. These diverse uses make helium-3 a highly strategic resource, sparking a competitive race among nations, notably the United States, China, and Russia, with the European Union, India, and others also entering the fray. The Moon’s helium-3 reserves are estimated to be vast—possibly around a million metric tons—though dispersed at very low concentrations, requiring processing of large amounts of lunar soil. Earth’s supply is limited and insufficient to meet the anticipated demand from scaling quantum technologies and other uses. While helium-3 fusion remains theoretical and
