【央视新闻】月球水从哪里来？这一重要发现开辟新思路

Core Insights - The research team from the Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, identified impact remnants from a type of carbonaceous chondrite known as "CI-type" in lunar soil samples from the Chang'e 6 mission, which are rich in water and other components [2][3] - This discovery opens new avenues for studying the distribution and evolution of water resources on the Moon, suggesting that materials from the asteroid belt can migrate into the inner solar system and contribute to lunar water sources [2] Research Findings - The study focused on a 2-gram sample of lunar soil, where researchers precisely identified seven micro-fragments rich in olivine, formed from the melting and rapid cooling of CI-type carbonaceous chondrite parent bodies upon impact with the Moon's surface [2] - CI-type carbonaceous chondrites are primarily found in the outer solar system and are characterized by their high volatile content, including water and organic materials [2] - The proportion of these chondrites on the Moon's surface is significantly higher than that on Earth, indicating their potential contribution to lunar water sources [2] Future Research Directions - The research team plans to conduct further studies to quantify the amount of water that may have been delivered to the Moon by these types of chondrites, as their previous contributions to lunar water sources have likely been underestimated [3]
