【科技日报】嫦娥六号月壤“黏性”之谜揭开

Core Insights - The latest research on the Chang'e 6 lunar soil reveals its unique "stickiness" due to specific particle interactions, which differ from the lunar soil samples collected by Chang'e 5 [1][2] Group 1: Research Findings - The Chang'e 6 lunar soil exhibits a higher repose angle, indicating greater stickiness compared to the lunar soil from the Chang'e 5 mission, which suggests different physical properties [1] - The research identified three key particle interactions—friction, van der Waals forces, and electrostatic forces—that contribute to the higher repose angle and thus the stickiness of the lunar soil [1][2] - The unique characteristics of the Chang'e 6 lunar soil, including its finer and more irregular particles, enhance the contributions of these forces, leading to its increased cohesiveness [2] Group 2: Implications for Future Missions - The findings provide critical scientific insights for future lunar exploration missions, particularly regarding the stability of landers and the potential for lunar dust dispersion during landing [2] - The research supports the development of lunar bases and resource utilization on the Moon, aligning with China's advancing deep space exploration initiatives [2]
