Illumination-Prior-Based High-Resolution DEM Reconstruction from Single-View Lunar Image Constrained with Initial DEM [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
The lunar south pole is characterized by complex illumination conditions, extensive shadowed regions, and rugged topography, which make high-resolution terrain reconstruction from single-view imagery particularly challenging.

The Distribution of Molecular Water in the Lunar South Polar Region Based upon 6 μm Spectroscopic Imaging

The Planetary Science Journal, 2023
The amount and distribution of water on the lunar surface are related to the input and production of water by solar wind and meteoroid bombardment, balanced by photodestruction and mobility across the surface.

Models of the distribution and abundance of hydrogen at the lunar south pole [PDF]

Geophysical Research Letters, 2007
Permanently shadowed locations at the lunar poles are potential sites for significant concentrations of cold‐trapped volatiles, including water ice. Hydrogen enhancements are seen at the poles, but the physical form, abundance and distribution of this hydrogen remains controversial.

A newly-identified spectral reflectance signature near the lunar South pole and the South Pole-Aitken Basin [PDF]

Earth, Planets and Space, 2008
Abstract Signal analysis of Galileo images of the Moon suggests the presence of an absorption band centered near 0.7 μm in the reflectance spectra of areas located adjacent to the equatorward walls of lunar craters at latitudes ranging from −58 to −78°, and areas contained in the South Pole-Aitken Basin.

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.

Constraints on the volatile distribution within Shackleton crater at the lunar south pole [PDF]

Nature, 2012
Shackleton crater is nearly coincident with the Moon's south pole. Its interior receives almost no direct sunlight and is a perennial cold trap, making Shackleton a promising candidate location in which to seek sequestered volatiles. However, previous orbital and Earth-based radar mapping and orbital optical imaging have yielded conflicting ...
