Scientists in China recently made an exciting discovery while examining rock samples from the Moon’s far side. They found fragments of a rare meteorite that could shed light on the Solar System’s history. These samples were collected by China’s Chang’e-6 mission and returned to Earth in June 2022. Interestingly, the fragments resemble material from asteroids that predate the formation of the Solar System. By studying them, researchers hope to learn how asteroids contributed water and other essential compounds to planets like Earth and our Moon.
Yuqi Qian, a planetary scientist at the University of Hong Kong, noted that this finding wasn’t on the original list of mission goals. “It’s such an unexpected and important finding,” he commented, highlighting the significance of the discovery.
The team published their findings in the Proceedings of the National Academy of Sciences. Unlike past lunar missions that focused on the near side of the Moon, where volcanic activity is more evident, Chang’e-6 land on the far side. This area, known as the South Pole–Aitken Basin, is the Moon’s largest and deepest crater, making it a prime spot for understanding the Moon’s geological history.
This crater formed about four billion years ago from a massive asteroid impact. It not only holds traces of that event but also samples from the lunar mantle, the layer below the crust. Researchers believe the basin’s structure makes it a rich source for studying the Moon’s past.
Initially, researchers thought the fragments originated from the Moon’s mantle. However, by examining the levels of iron, manganese, and zinc, they discovered a mismatch with other lunar materials. To further verify the origin, they analyzed oxygen isotopes, which can identify the source of the debris. “This approach is basically space forensics,” said Mang Lin, a geochemist involved in the research.
In recent years, there has been a growing interest in lunar exploration. According to a survey by the Pew Research Center, about 63% of Americans support sending humans back to the Moon, emphasizing the public’s fascination with lunar missions and the potential for new discoveries.
These findings not only provide insight into the Moon’s history but also raise questions about the broader cosmic narrative. As we learn more about the Moon and other celestial bodies, we piece together our place in this vast universe. With continued research and exploration, who knows what other surprises are waiting for us in space?
