Lunar Polar Dichotomy: Insights from Crater Morphometry

The Planetary Science Journal
The lunar poles exhibit a puzzling dichotomy in crater depth-to-diameter ( d / D ) ratios. At the south pole, crater depths decrease toward the pole, and previous studies have mainly attributed this trend to water-ice infilling.

Global Lunar Crater Density Using Buffered Nonsparseness Correction

The Planetary Science Journal
The density of craters on a planetary surface directly relates to the age of the surface. As the surface ages, however, craters can be erased by subsequent large impacts via direct overprinting, known as geometric crater obliteration.

Evaluating Lunar Crater Ejecta Maturation across Wavelengths

The Planetary Science Journal
Ejecta blankets of young lunar craters provide an important window into the maturation processes of material at the lunar surface. As freshly exposed material degrades, the signature of that material changes in remote sensing data.
