China has quietly crossed a threshold in the global race for lunar resources. With the China Aerospace Science and Technology Corporation confirming that a “Tiangong Kaiwu” (Heavenly Craft and the Creation of Things) space-resource development programme will enter substantive national-level feasibility studies during the 15th Five-Year Plan period, Beijing has effectively moved lunar mining from long-term scientific aspiration into the realm of industrial planning.
In the world of space policy, such language matters. Once a project reaches state-level technical and economic “demonstration” status, it is no longer about whether it can be done, but how, by whom, and on what timetable. The shift suggests China’s lunar ambitions are evolving from exploration toward early-stage industrial exploitation — a development with implications far beyond space science.
At the centre of this quiet escalation lies helium-3, an isotope often described as the “ideal fusion fuel.” And while the United States and its partners have rushed back to the Moon through programmes such as Artemis, the decisive contest may no longer be about who arrives first, but who can extract resources at viable cost.
The resource that reshapes the race
Helium-3 is prized because fusion reactions involving it generate immense energy with minimal neutron radiation, avoiding many of the waste and material-degradation problems associated with current nuclear technologies. Estimates cited by researchers suggest that roughly 100 tonnes of helium-3 could theoretically power the entire world for a year. On Earth, however, the isotope is vanishingly rare — global reserves amount to about 500 kilograms, sourced mainly from tritium decay or trace extraction in natural gas.
The Moon tells a different story. With no atmosphere to shield it from the solar wind, lunar soil has accumulated helium-3 over billions of years. Scientific estimates place the amount embedded in the Moon’s shallow regolith at around 1.1 million tonnes, with upper projections reaching as high as 5 million tonnes — enough, at the lower estimate alone, to supply humanity’s energy needs for roughly 10,000 years.
That prospect explains the renewed international push toward the Moon, from NASA’s Artemis programme to Russian plans for a lunar base by 2035, and a steady stream of missions from Europe, Japan and India. What held everyone back until now was not the absence of helium-3, but the cost of getting it out.
A lower-energy extraction breakthrough
For decades, the prevailing assumption was that helium-3 could only be released by heating lunar soil to more than 700°C — an energy-intensive process in the Moon’s vacuum environment, where power generation, heat dissipation and logistics are all severely constrained. The result was a paradox: mining the Moon for energy would itself consume enormous amounts of energy.
That equation changed after China’s Chang’e-5 mission returned 1,731 grams of lunar samples to Earth. Analysis by Chinese scientists revealed that helium-3 is not evenly distributed throughout lunar soil. Instead, it is largely trapped in ultra-thin layers of amorphous glass coating ilmenite particles — a structure formed by micrometeorite impacts and prolonged solar-wind exposure. Within this glass, helium-3 exists as microscopic gas bubbles.
This finding opened the door to an alternative extraction pathway. Rather than heating tonnes of regolith to extreme temperatures, researchers proposed a mechanical crushing method to break the glass structure and release the gas at near-ambient temperatures. Experimental data indicate this approach could reduce energy consumption by roughly 70% compared with thermal extraction — a margin large enough to transform an uneconomic concept into a potentially viable industry.
The logic underpinning China’s new programme now appears complete: discovery, extraction theory, energy economics and early engineering validation.
From concept to machines
Turning theory into practice requires hardware capable of operating in one of the harshest environments known. Lunar gravity is one-sixth of Earth’s, surface temperatures swing by more than 300°C between day and night, vacuum conditions complicate heat management, and abrasive lunar dust infiltrates mechanical systems with ease.
Chinese researchers are already testing solutions. China University of Mining and Technology has developed prototype “interstellar miner” systems featuring six-legged hybrid locomotion — combining wheels for flat terrain with articulated legs for uneven surfaces. In microgravity conditions, these machines use insect-inspired claw mechanisms to anchor themselves to the surface, preventing recoil forces from destabilising excavation.
On Earth, China has built what it describes as the world’s first engineering-scale physical simulation system capable of reproducing low-gravity fields, ultra-high vacuum and extreme temperature differentials simultaneously. Within this environment, researchers are testing end-to-end mining workflows.
Complementing extraction is collection. Scientists at the Chinese Academy of Sciences’ Hefei Institutes have developed carbon-nanotube sponge materials capable of adsorbing helium-3 with reported capture efficiencies of 98.7% under simulated lunar conditions. Combined with mechanical crushing and magnetic separation of ilmenite, a complete low-energy processing chain has now been demonstrated in laboratory settings.
Strategic pressure and competing rules
These developments help explain Washington’s renewed urgency. While US firms such as SpaceX have transformed launch economics, and Intuitive Machines’ Odysseus lander reached the Moon — albeit with a compromised landing — the United States has not publicly demonstrated a comparable low-energy extraction pathway for helium-3.
Instead, the US has focused on legal and regulatory positioning. The 2015 Commercial Space Launch Competitiveness Act and the later Artemis Accords establish that private entities may own resources they extract, and allow for “safety zones” around operational sites. Critics argue this amounts to de facto resource enclosure, sidestepping the spirit of the United Nations’ Moon Agreement, which treats lunar resources as the common heritage of humanity.
Control of the lunar south pole is particularly sensitive. The region offers near-continuous sunlight for power generation and hosts confirmed water ice deposits. China’s Chang’e-7 mission, scheduled for around 2026, is aimed squarely at mapping these ice reserves. Water is not only vital for life support but can be split into hydrogen and oxygen — ideal rocket propellants — turning the Moon into a refuelling hub for deeper-space missions.
A long, disciplined timeline
China’s approach is notable for its clarity and sequencing. The roadmap mirrors the earlier “orbit, land, return” framework that underpinned its lunar programme:
– Around 2026: Chang’e-7 targets the lunar south pole to confirm water-ice distribution; the Long March-10A heavy-lift rocket conducts its maiden flight.
– Around 2028: Chang’e-8 supports construction of the basic framework for an International Lunar Research Station and conducts on-site resource-utilisation experiments.
– Before 2030: A crewed Chinese lunar landing using the Mengzhou spacecraft and Lanyue lander.
Wu Weiren, chief designer of China’s lunar programme, has described a three-phase vision: exploration before 2030, infrastructure and limited resource use before 2040, and scaled industrial development before 2050.
The implications extend beyond helium-3. Ilmenite processing yields iron, titanium and oxygen — construction materials and life-support resources. Rare earth elements are present in certain lunar rock formations. Combined with polar water ice, these resources could enable sustained off-Earth industrial cycles.
The emerging competition, then, is not simply about flags or footprints. It is about who first transitions from explorer to miner — and eventually to permanent industrial operator beyond Earth. China’s latest move suggests that, in this contest, incremental laboratory discoveries and methodical engineering may matter more than dramatic landings.
If future historians look for the inflection point in the modern lunar race, it may not be a launch or a landing, but a set of experiments quietly proving that Moon mining can finally make economic sense.
