Chinese material scientists have found the soil on the moon may potentially be able to generate oxygen and fuel, a finding that means more possibilities of humans to use lunar resources to further exploration of the moon and beyond.
The researchers at Nanjing University showed that the lunar sample brought back by China’s Chang’e-5 contains active compounds (化合物) that can change carbon dioxide into oxygen and fuel. Initially, they hoped to design a system that took advantage of lunar soil and solar radiation, the two rich resources on the moon, according to a study published on Thursday in the journal Joule.
After analyzing the Chang’e-5’s lunar soil, the team found the sample contained metal-rich substances, which could work as a catalyst (催化剂) to make oxygen using sunlight and carbon dioxide. The team proposed a strategy using lunar soil to electrolyze water from the moon and the astronauts’ life support system into oxygen and hydrogen. The process was powered by sunlight. The carbon dioxide breathed out by moon inhabitants can be collected and combined with hydrogen to produce the fuel, also catalyzed by the lunar soil, according to the study. The researchers said with this method, no external energy apart from sunlight would be used to produce oxygen and fuel to support life on a moon base.
“We use the environmental resources to minimize rocket payload, and our strategy provides a scenario for a sustainable and affordable living environment for life out of the Earth,” said the paper’s first author Yao Yingfang from Nanjing University, expressing his assumption.
“The challenge lies in the fact that catalytic efficiency of lunar soil is lower than catalysts on the Earth,” said the researchers. They are testing different approaches in order to improve the design. The team is looking for an opportunity to test the system in space with China’s future manned lunar missions.
8. What is the main implication of Chinese scientists’ discovery of the moon’s soil
A. The moon is rich in rare elements. B. Lunar soil can be used for exploring space.
