Mining on the Moon extracting Helium 3.

Mining on the Moon extracting Helium 3.

The moon, which for centuries inspired poetry and exploration, now becomes the scene of a much more concrete dispute, the search for helium 3, a rare isotope on Earth, but abundant in lunar soil. After billions of years of exposure to the solar wind, this substance awakens scientific, technological and geopolitical ambitions because it can play decisive roles in cutting-edge areas, from the cooling of quantum computers to clean fuel for nuclear fusion reactors.

On Earth, helium 3 is obtained only in small quantities from the decomposition of tritium in nuclear stocks, not enough to sustain the growing demand. On the Moon, however, it is estimated that there are up to 1 million metric tons dispersed in the regolith, although in very low concentrations, this disparity makes the satellite a strategic objective for whoever masters the extraction technology.

The immediate value of helium 3 is in the quantum world, mixed with helium 4 it powers the dilution refrigerators that cool qubits to temperatures of 1000 Kelvin, about 200 times colder than outer space, that almost absolute cold is what allows the fragile quantum states to survive long enough to perform calculations.

As quantum data centers expand, demand for helium-3 could explode, far outpacing terrestrial production, but the most tantalizing promise lies in clean nuclear fusion. Unlike fusion with deuterium and tritium that releases highly radioactive neutrons, fusion with IO3 generates charged particles with much less long-term nuclear waste.

In theory, a few dozen tons could feed entire nations, it is a vision still distant, but powerful enough to motivate global strategic plans. The challenge, however, is colossal, each liter of helium 3 would require processing tons of abrasive, sticky and difficult to handle lunar regolith powder.

To extract the gas it would be necessary to heat the ground to high temperatures, separate helium 3 from helium 4 and store it in safe conditions. Startups like Interlune are already designing machines capable of crossing the lunar surface collecting, heating and releasing the regolith while isolating the valuable isotope. All of this will require robust power sources such as solar concentrators or small nuclear reactors, as well as highly autonomous remote operations.

And this is where science meets geopolitics, the United States and China lead the race, each with different strategies, Washington is betting on the Artemis agreements and incentives for private companies, even going so far as to make the first symbolic government purchase of 3 Liters of Helium 3. Beijing, for its part, sees the resource as key to meeting its energy needs for thousands of years, linking the Lunar Change program with long-term national goals.

Russia, the European Union and India are also trying to secure a place in this dispute that could redefine the global balance, the story of helium 3 is more than mining, it is about who will have the courage and technical capacity to transform lunar dust into energy and power. The next decade may reveal whether this dream will become a new energy revolution or whether it will remain one of humanity's greatest unfulfilled promises.
