Lunar PSRS South Polar Region

Caption

The scientists used AstroGeo22 and LOLA height measurements to calculate the age of the Moon’s permanently shadowed regions near its poles. Colored patches show the extent of PSRs 3.3 billion years ago (red), 2.1 billion years ago (green) and close to present-day (blue) with current topography. These findings suggest that current estimates for cold-trapped ices are too high.
