No evidence for thick deposits of ice at the lunar south pole
Nature, 2006Shackleton crater at the Moon's south pole has been suggested as a possible site of concentrated deposits of water ice, on the basis of modelling of bi-static radar polarization properties and interpretations of earlier Earth-based radar images. This suggestion, and parallel assumptions about other topographic cold traps, is a significant element in ...

CHARACTERIZATION OF SHADOWED REGIONS AT THE LUNAR SOUTH POLE
2022This image repository contains a total of 576 non map-projected HORUS (Hyper-effective nOise Removal Unet Software) post-processed images of permanently shadowed regions (PSRs) located across the Artemis exploration zone at the lunar south pole (144 individual images).

Design of a Robotic Lunar Lander for Lunar South Pole Exploration
AIAA SPACE 2008 Conference & Exposition, 2008In 2005 Ball Aerospace & Technologies Corporation performed conceptual and systems level design work for a lunar polar robotic Lander, to meet the requirements of the Robotic Lunar Exploration Program (RLEP) precursor robotic missions to the Moon. The study presented in this paper developed Lander concepts using Ball heritage bus architectures.

Optimal placement of solar reflectors at the lunar south pole
2016 IEEE International Conference on Systems, Man, and Cybernetics (SMC), 2016A recent NASA Innovative Advanced Concepts study suggests that several reflectors placed around the perimeter of Shackleton Crater may be capable of redirecting uninterrupted solar energy to a region within the crater year-round—effectively creating an energy oasis in the otherwise dark and cold extreme environment.

Structure of the South Pole-Aitken lunar basin
Solar System Research, 2007The hypsometric map and the basin height profiles, for the first time relying upon a spherical daturence surface, have been constructed based on the generalization of the heights measured within the hemisphere including the ring structure of the South Pole-Aitken basin.

Solar Sails and Lunar South Pole Coverage
AIAA/AAS Astrodynamics Specialist Conference and Exhibit, 2008Potential orbits for continuous surveillance of the lunar south pole with just one spacecraft and a solar sail are investigated. Periodic orbits are first computed in the EarthMoon Restricted Three-Body Problem, using Hermite-Simpson and seventh-degree GaussLobatto collocation schemes.

A Concept for Robotic Lunar South Pole Exploration
Space 98, 1998The lunar south pole region may contain frozen volatiles such as water and carbon dioxide in surface depressions which are permanently dark. The low Sun angles of the region create these permanently dark areas and also provide nearby regions of long term sunlight and moderate temperatures which benefit robotic exploration. In this paper a concept for a

Long‐period lunar tides at the South Pole
Journal of Geophysical Research: Solid Earth, 1982Vertical gravity data from 6.3 years of observations at the geographic South Pole have been analyzed to determine the gravimetric factor and phase angle of the long‐period tides. Annual and semiannual tides are obscured by the combination of signals arising from instrumental drift and the large annual component of barometric pressure changes at Pole ...

Why the lunar South Pole-Aitken Basin is not a mascon
Icarus, 2020Abstract Lunar mascon basins exist for only a range of observed diameters. We modeled the full formation of South-Pole Aitken basin using a sequential two-code (hydrocode and Finite Element Model) approach to understand why this range does not extend to the largest lunar basin. Similar to previous work, we found that the best-fit hydrocode had impact

LANDSLIDE SUSCEPTIBILITY MAPPING IN LUNAR SOUTH POLE RIGION
SGEM International Multidisciplinary Scientific GeoConference� EXPO ProceedingsThe study addresses a challenge in planetary exploration, focusing on landslide susceptibility on the Lunar South Pole Region (LSPR), fundamental for future lunar missions. Features like permanently shadowed regions and water ice deposits attract scientific attention but issues related to rugged terrain and dynamic geological processes must also to be ...
