颗粒力学揭示嫦娥六号月壤黏性之谜

Core Viewpoint - The research team led by researcher Qi Shengwen from the Institute of Geology and Geophysics of the Chinese Academy of Sciences has revealed the physical mechanisms behind the high viscosity characteristics of lunar soil samples from the Chang'e 6 mission, providing a comprehensive explanation of why the lunar soil is so sticky [2][3]. Group 1: Research Findings - The study utilized high-resolution CT scanning at a scale of 1 micron to analyze over 290,000 lunar soil particles, comparing them with samples from the Chang'e 5 and Apollo missions [2]. - The D60 value of the Chang'e 6 lunar soil was found to be the smallest at 48.4 microns, indicating finer particles with more complex shapes and significantly lower sphericity [2]. - The presence of easily breakable feldspar minerals, which constitute approximately 32.6% of the sample, and the stronger space weathering effects on the far side of the moon are believed to contribute to the unique characteristics of the Chang'e 6 lunar soil [2]. Group 2: Implications for Future Research - This research provides crucial scientific evidence for future lunar exploration missions, aiding in the construction of lunar bases and the development of lunar resources [3]. - The findings are expected to support China's advancements in lunar scientific research and resource utilization, contributing to new breakthroughs in these fields [3].
