Scientists Map Moon Regolith to Aid Future Lunar Bases

• Researchers from Brown University have mapped the global thickness of lunar regolith to support future infrastructure development.
• The study analyzed 346 impact craters across 13 lunar regions to provide precise, open-source data for base construction.
• Findings show mare regolith is approximately 4 meters (13 feet) thick, while highland regolith averages 6 meters (20 feet).

Implications for Lunar Construction

• Establishing accurate regolith thickness is critical for identifying stable foundations for permanent habitats.
• Thinner regolith may allow easier access to solid material for building foundations, while thicker deposits might contain valuable resources like water ice or helium-3.
• The data supports NASA’s plans for a permanent base near the lunar south pole, where permanently shadowed craters could provide accessible water ice.

Resource Utilization and Future Missions

• The research promotes "in situ resource utilization" (ISRU), enabling crews to "live off the land" and reduce reliance on supplies from Earth.
• This methodology serves as a framework for other airless bodies, potentially including Mercury, the moons of Mars, and several moons of Jupiter and Saturn.
• While Mars is a long-term goal, its active weather patterns make similar regolith mapping significantly more complex.
