Technology Uses Sunlight to Transform Lunar Soil into a Source of Water, Oxygen, and Fuel, Paving the Way for More Autonomous Missions in Space
Scientists from China announced a breakthrough that could transform the future of space exploration. The team led by Lu Wang developed a technology capable of extracting water from lunar soil and converting it into oxygen and hydrogen.
The achievement was published in the scientific journal Joule on the 16th, based on samples collected by the Chang’E-5 mission.
Water and Life in Space
The discovery addresses one of the main challenges faced by space missions: obtaining basic resources such as water and oxygen without relying on transportation from Earth.

In Andradina, in the interior of SP, a tannery transformed tilapia skin that slaughterhouses used to throw away into exotic leather for bags, shoes, and even wedding dresses, producing about 2,000 pieces per month and exporting to seven countries, proving that fish waste has become high-value fashion.

The industrial waste that even recyclers didn’t want has gained value in the interior of Bahia: two entrepreneurs invested R$ 2.8 million to transform 350 tons per year of foam, rubber, and plastic into boards that can replace wood and MDF.

He has never read a line of code, but he already knows how to work: the French company UMA presented in Paris the Northstar, its first AI-powered humanoid robot designed for factories and warehouses, capable of copying tasks just by observing an employee in action.
The cost of sending a single gallon of water into space is around US$ 83,000. As each astronaut requires four gallons per day, the total expenditure on missions can be exorbitant. The new technique could drastically reduce this cost.
Lu Wang emphasized that the combination of water extraction with the conversion of CO₂ into oxygen is a practical solution.
According to him, the approach reduces the complexity of the infrastructure needed to support humans on the Moon.
The Innovation of the Method
The technology’s uniqueness lies in its use of a photothermal strategy. With this, sunlight is used to generate the necessary heat for the chemical process.
Water is extracted from the lunar soil, rich in a mineral called ilmenite, and this allows for the transformation of the carbon dioxide exhaled by astronauts into carbon monoxide and gaseous hydrogen.
These two elements can be used for both oxygen generation and fuel production, paving the way for more autonomous and sustainable missions.
Tests with Lunar Material
The study was not limited to actual samples from the Chang’E-5 mission. Experiments were also conducted with simulated materials, using a reactor that concentrated sunlight to carry out the process.
The scientists confirmed that the ilmenite present in lunar soil contains useful water reserves for this type of conversion.
The team noted that previous methods had very high energy consumption and low efficiency in converting CO₂.
The new system proved to be more promising, overcoming the limitations faced by earlier technologies.
Challenges Still Persist
Despite the positive results, the scientists warn that there are significant obstacles. The lunar surface presents extreme conditions, such as drastic temperature variations, high radiation, and low gravity.
Moreover, lunar soil is not uniform, which may hinder the application of the technique on a large scale.
Even with these challenges, researchers believe that, with technological advancements and cost reductions, it is possible to turn this innovation into a practical solution for future missions.
The expectation is that the new method will contribute not only to the use of lunar water but also to ensuring the survival of astronauts in environments beyond Earth.
This advancement could be the key to a continuous human presence on the Moon and, in the future, on other planets.
