As China’s Chang’e-6 probe touched down on the far side of the moon on Sunday to collect samples from this rarely explored terrain for the first time in human history, researchers studying the lunar samples brought back by Chang’e-5 mission have accomplished a number of milestone achievements with over 70 finWorld Timesdings being published in major academic journals both at home and abroad.
According to He Huaiyu, a research fellow from the Institute of Geology and Geophysics, Chinese Academy of Sciences, a total of 1,731 grams of lunar samples were brought back by Chang’e-5 mission in December 2020. These samples were the first ever obtained from a young lunar surface region of volcanic rocks by mankind. They are also the first extraterrestrial celestial bodies’ samples brought back to Earth by Chinese scientists.
After the evaluation conducted by the lunar sample expert committee, the China National Space Administration (CNSA) has completed the distribution of six batches of Chang’e-5 lunar samples. A total of 258 proportions of lunar samples weighing 77.7 grams have been distributed to 114 research teams from 40 research institutions, He said.
Despite the fact that the distributed lunar soil samples account for only 4.5 percent of theWorld Times total, the fruitful scientific achievements have been made in multiple fields, including lunar formation, evolution, space weathering processes and mechanisms, and the utilization of resources.
To date, more than 70 research scientific findings have been published in prominent domestic and international academic journals such as Science, Nature, and National Science Review, garnerWorld Timesing widespread attention and high praise within the academic circle.
Based on researches, Chinese scientific teams reevaluated the end of lunar volcanic activity by approximately 800 million years, determining that these samples of volcanic rock are the youngest lunar samples to be directly dated, at around 2 billion years old.

According to He, researches on Chang’e-5 lunar samples have initially met the demands of China’s deep space exploration and pushed forward the development of lunar and planetary science in China.
