科研人员揭开嫦娥六号月壤黏性之谜

Group 1 - The research team from 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, published in the journal Nature Astronomy [1] - The team conducted fixed funnel and drum experiments to measure the repose angle of the lunar soil, finding it significantly higher than that of lunar samples from the front side, indicating flow characteristics closer to viscous soils on Earth [1] - The unique particle characteristics of the Chang'e 6 lunar soil, including a high content of easily breakable feldspar minerals (approximately 32.6%), contribute to its higher viscosity due to increased friction, van der Waals forces, and electrostatic forces [1] Group 2 - The research findings will provide a critical theoretical foundation for lunar base construction and resource utilization, supporting advancements in lunar scientific research and resource development [2]
