Moon mining mission to extract helium-3 in bid to alleviate extreme supply shortages on Earth
Two space firms have signed an agreement to start mining “commercial quantities” of helium-3 isotopes on the Moon and bring them back to Earth where there is an extreme supply shortage. In a joint statement, Japanese firm ispace and Magna Petra said their mining activities would utilise “non-destructive” and “sustainable” techniques to harvest the resources from regolith (the layer of unconsolidated solid material covering the bedrock of a planet) on the lunar surface. Helium-3 is a stable isotope of helium and is predominantly used for nuclear fusion reactions with deuterium (heavy hydrogen) to produce large amounts of energy. Because helium-3 is not radioactive, the fusion process doesn't produce nuclear waste or greenhouse gas emissions. For many years, the supply of helium-3 from…
