Chinese Scientists Solve Mystery of Moon's Sticky Soil
The Chang'e-6 soil's cohesion is due to fine particle size below 50 micrometers and combined friction, Van der Waals, and electrostatic forces, scientists reported.
- Chinese scientists have solved the mystery of the cohesive lunar soil from the Chang'e-6 mission, revealing its unique properties compared to near-side samples, as published in Nature Astronomy.
- The research team conducted experiments showing that the Chang'e-6 soil has a higher angle of repose and is more similar to cohesive terrestrial soils' flow properties.
- Researchers identified that interparticle forces, particularly Van der Waals and electrostatic forces, contribute significantly to the soil's cohesion.
- The insights gained are deemed crucial for future lunar exploration missions, especially for activities like lunar base construction and resource utilization.

Researchers discover latitude- and regolith-dependent distribution of lunar surface water
A research team from the Institute of Geology and Geophysics of the Chinese Academy of Sciences (IGGCAS) has found that lunar soil samples brought back by China's Chang'e-6 mission (collected from the lunar farside) contain high concentrations of OH/H2O and low deuterium-to-hydrogen (D/H) ratios. These characteristics align with lunar water originating from the solar wind, the team noted.
