Moon Dust's Jaggedness Could Aid Lunar Construction

Research on lunar dust returned by the Chang'e 6 mission reveals that the jagged properties of regolith from the far side of the Moon could be advantageous for future lunar construction. Unlike the smoother particles found on the near side, the far side dust exhibits high internal friction and cohesion, making it exceptionally strong. This strength is attributed to the jaggedness of the particles and the presence of glassy agglutinates, which act as a cement to hold the particles together. The use of non-destructive testing methods, such as high-resolution x-ray micro-computer tomography, allowed researchers to analyze the properties of the dust without destroying the limited sample. The findings suggest that the far side regolith could provide a stable foundation for building infrastructure, such as habitats and research facilities. However, the jaggedness of the dust also presents challenges, as it can be abrasive and potentially harmful to machinery and astronaut health. Further research is needed to develop strategies for mitigating these risks and fully harnessing the potential of lunar regolith for in-situ resource utilization. The study highlights the importance of understanding the unique properties of lunar materials for enabling sustainable lunar exploration and development.
