Guangzhou, China – A groundbreaking discovery by an International team of Scientists studying samples returned from the Moon’s far side by China’s Chang’e-6 mission has revealed evidence of a remarkably rare meteorite. This finding, published in the prestigious journal Proceedings of the National Academy of Sciences, suggests a more active exchange of material between the inner and outer Solar System than previously understood.
Unveiling CI Chondrites on the Lunar Surface
The research, spearheaded by experts at the Guangzhou Institute of Geochemistry (GIG) under the Chinese Academy of Sciences (CAS), centers around CI chondrites. These meteorites are extraordinarily scarce on Earth, composing less than one percent of all meteorite collections. The Moon, however, presents a unique opportunity for preserving ancient impact records due to its lack of substantial atmosphere and geological activity like plate tectonics, effectively functioning as a “natural archive” of space debris.
Employing advanced techniques to analyze the mineral composition and oxygen isotopes within the lunar soil, the team definitively identified fragments originating from CI-like chondrites. These meteorites are notably rich in water and organic compounds, typically originating from the outer reaches of our Solar System.
Implications for Water’s Origin on the Moon
The presence of these meteorites indicates the Earth-moon system may have endured a greater number of impacts from carbonaceous chondrites than earlier models predicted. This challenges existing theories regarding the delivery of volatile compounds,like water,to the Moon. Lin Mang, a researcher at GIG, explained this discovery implies material from the outer Solar System can, in fact, migrate towards the inner Solar system. This breakthrough offers critical insights into the potential origins of water found on the lunar surface.
Recent data from NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) confirmed water molecules are present in sunlit areas of the Moon, challenging previous assumptions about the lunar habitat. Learn more about NASA’s findings.
A New Method for Identifying Space Debris
Beyond the implications for understanding Solar System evolution, this research also establishes a systematic approach for identifying meteorite material within samples collected from space. This will prove invaluable for future missions aiming to analyze materials from asteroids, comets, and other celestial bodies.
Chang’e-6 Mission: A Historic Undertaking
The Chang’e-6 mission,completed in 2024,successfully retrieved 1,935.3 grams of lunar samples from the South Pole-Aitken (SPA) Basin.This massive basin, located on the far side of the Moon, is the largest, deepest, and oldest known impact crater in the Solar System. The collected samples provide a unique window into the Moon’s ancient past.

Understanding Meteorites and Their Significance
Meteorites are remnants of asteroids, comets, and even other planets that have survived their passage through Earth’s atmosphere and landed on the surface. Thay provide invaluable insights into the composition and history of the Solar System. Different types of meteorites, like CI chondrites, offer unique clues about the building blocks of planets and the conditions present during their formation.
Frequently Asked Questions About the lunar Meteorite Discovery
- What are CI chondrites? CI chondrites are a rare type of carbonaceous chondrite meteorite, rich in water and organic molecules, originating from the outer Solar System.
