Discoveries provide pioneering insights into water exploration on the Moon and shed light on the future construction of lunar research stations
About the writer
Chinese Academy of Sciences (CAS) researchers have developed a new method of massive water production on the Moon.
Previous lunar explorations have found the water content in lunar minerals to be extremely low, ranging from 0.0001% to 0.02%, they note. Now Prof. Wang Junqiang’s team at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS) has developed a new method of massive water production based on the reaction between lunar regolith and endogenous hydrogen.
Concentrated heating regolith releases water
“We used lunar regolith samples brought back by the Chang’E-5 mission in our study,” said Wang. The study revealed that when the lunar regolith is heated above 1,200 K with concave mirrors, one gram of molten lunar regolith can generate 51 to 76 mg of water.
“So one ton of lunar regolith could produce more than 50 kg of water, which is equal to about a hundred 500-ml bottles of drinking water. This would be enough drinking water for 50 people for one day.”
Lunar ilmenite (FeTiO3) was found to contain the highest amount of solar wind-implanted hydrogen among the five primary minerals in the lunar regolith, owing to its unique lattice structure with sub-nanometer tunnels.
Other options: irrigating and breathing
The researchers suggest that this water could be used both for drinking and irrigating plants. Or it could be electrochemically decomposed into hydrogen and oxygen, with hydrogen used for energy and oxygen essential for breathing.
The researchers say these discoveries provide pioneering insights into water exploration on the Moon and shed light on the future construction of lunar research stations.
The results of the study were published in the Cell Press journal The Innovation.

This is just from legendary space writer Howard Bloom: "This shows that the Chinese are thinking big, producing enough water for 50 taikonauts [Chinese astronauts]. We are still thinking in terms of two to four astronauts on the moon at a time. But we are about to have a tool that dwarfs the rockets of the Chinese. We are about to have the hundred-passenger SpaceX Starliner. So it's time to up our Moon goals and to think of building colonies that can house hundreds or even thousands of people at a time. Las Vegas-style tourist attractions and science labs. Even two-week courses for college students on the moon. — Howard Bloom, the man Britain's channel 4 tv calls the Einstein, Darwin, Newton and Freud of the 21st century, author of the upcoming January 2025 book The Case of the Sexual Cosmos: Everything You Know About Nature is Wrong."
