The ESA Lunar Robotics Challenge: Simulating operations at the lunar south pole [PDF]
Journal of Field Robotics, 2012 AbstractIn 2008, the European Space Agency (ESA) challenged universities to design, develop, and test teleoperated robotic systems for a soil‐sampling mission in a simulated lunar‐crater‐like environment. Eight teams participated and developed a wide range of engineering solutions that addressed the various technical and operational challenges posed by

Illumination conditions at the lunar South Pole [PDF]
Geophysical Research Letters, 1999 Recent remote sensing data strongly suggest that deposits of ice occur in permanently shadowed regions at the lunar poles. Clementine, by providing the first contiguous coverage of the Moon, has enabled the production of an illumination map of the south pole.

Design of optimal transfers between North and South Pole-sitter orbits [PDF]
, 2012 Recent studies have shown the feasibility of an Earth pole-sitter mission, where a spacecraft follows the Earth’s polar axis to have a continuous, hemispherical view of one of the Earth’s Poles.

Lunar Prospecting: Searching for Volatiles at the South Pole [PDF]
SpaceOps 2016 Conference, 2016 The Resource Prospector is an in-situ resource utilization (ISRU) technology demonstration mission, planned for a 2021 launch to search for and analyze volatiles at the Lunar South Pole. The mission poses unique operational challenges. Operating at the Lunar South Pole requires navigating a surface with lighting, shadow and regolith characteristics ...

Shape-from-Shading Derived DEMs from ShadowCam Images in Permanently Shadowed Regions at the Lunar South Pole: A First Look [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information SciencesThe lunar south pole, particularly its permanently shadowed regions (PSRs), has been the focus of future lunar exploration. The solar altitude angle at the lunar south pole is less than ∼ 2°, resulting in the PSRs not being directly illuminated ...
