The soil on the Moon could support life, scientists say
That is thanks to a breakthrough new technology that could allow humans to survive on the Moon.
It could help support a broad hope, held by a range of countries, that future missions to the lunar surface could see humans stay there before heading further into the solar system.
That might only be possible if we are able to make the necessary fuel, water and other resources on the Moon itself, since flying them to the lunar surface could be impossible. It would cost $83,000 to ship a gallon of water to the Moon, for instance – and each astronaut would need four of those each day.
Using samples brought back from a Chinese mission to the Moon, however, scientists were able to find a new method that would allow the astronauts to get the water they need from the lunar soil. Previous attempts to do so have used large amounts of energy and didn't break down CO2, but the new system overcomes those problems.
It allows astronauts to extract water from the lunar soil with a novel system that uses light from the Sun and turns it into heat.
'We never fully imagined the 'magic' that the lunar soil possessed,' said Lu Wang of the Chinese University of Hong Kong, Shenzhen. 'The biggest surprise for us was the tangible success of this integrated approach.
'The one-step integration of lunar H2O extraction and photothermal CO2 catalysis could enhance energy utilization efficiency and decrease the cost and complexity of infrastructure development.'
There may still be problems with putting it to use, however. The Moon's surface comes with a host of other challenges, including extreme changes in temperature, low gravity and inconsistencies in the lunar surface.
The work is described in a new paper, 'Inherent lunar water enabled photothermal CO2 catalysis', published in the journal Joule.

Life on the Moon? Lunar soil could help humans live on the Moon, study finds
The soil on the Moon might be able to sustain life, according to a new study. Researchers from the Chinese University of Hong Kong developed a technology to extract water from lunar soil and used it to convert carbon dioxide into oxygen and chemical fuel. The technology does this by converting light from the Sun into heat. According to the study, published in the Cell Press journal Joule, the research could 'potentially open new doors for future deep space exploration' because it could mitigate the expensive costs needed to bring essential resources such as water to the Moon. A single gallon (3.78 litres) of water costs $83,000 (€71,230) to ship up by rocket, the study continued, with one astronaut drinking roughly four gallons (15.14 litres) a day. 'We never fully imagined the 'magic' that the lunar soil possessed,' said lead researcher Lu Wang.

The Moon's extreme lunar environment will still make it challenging to harvest more oxygen and water from the land, the study continued, because there are 'drastic temperature fluctuations,' radiation and low gravity to deal with. The CO2 emitted from the breaths of the astronauts won't be enough to supply all the water, fuel and oxygen that the team of astronauts might need.

Chinese Scientists Invent System for Extracting Oxygen, Water and Rocket Fuel From Moon Dust
Chinese researchers say they've devised a new way to extract water from lunar soil and convert it into fuel. As detailed in a new paper published today in the journal Joule, the team found that their proposed "photothermal strategy" — essentially converting light into heat — could effectively convert carbon dioxide from extracted water into carbon monoxide, hydrogen, and oxygen gas, a "potential route for sustaining human life on the Moon and enabling long-term extraterrestrial exploration." "The sustainable utilization of local resources is essential for long-term human survival on the Moon and beyond," the researchers write, pointing out that bringing water from Earth is cost-prohibitive at roughly $83,000 per gallon. "We never fully imagined the 'magic' that the lunar soil possessed," said Chinese University of Hong Kong, Shenzhen professor and coauthor Lu Wang in a statement. "The biggest surprise for us was the tangible success of this integrated approach," he added. "The one-step integration of lunar H2O extraction and photothermal CO2 catalysis could enhance energy utilization efficiency and decrease the cost and complexity of infrastructure development." While plenty of questions remain about our future efforts to harness local resources on the surface of the Moon, it's a glimmer of hope that humanity could indeed establish a more permanent and potentially sustainable presence there. For their research, the team focused on simplifying existing proposals for how to extract water from lunar regolith, which tend to be energy-intensive and stop short of breaking the water down into its usable elements. The researchers also propose using the extracted water to turn carbon dioxide exhaled by astronauts into carbon monoxide and hydrogen gas, which could be used to make fuels. The team tested their photothermal approach on actual Moon samples gathered during China's Chang'E-5 mission, which launched in November 2020, and collected samples from the northwest of the Moon's near side before returning to Earth. While their lab-based experiments turned out to be a success, the actual lunar surface will likely prove a far more challenging place to extract and convert lunar water. As the paper points out, radiation, low gravity, and extreme temperature fluctuations could complicate matters significantly. However, the advancements highlight how far the Chinese space program has come in a matter of years. A mere two decades ago, China was a distant underdog in the international space race. But now that the country is launching its own astronauts to space while the Trump administration is effectively looking to eviscerate NASA when it comes to space science, China could stand a chance to surpass the US in its plans to build a Moon base by 2035.
