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.

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 ...

A South Pole–Aitken impact origin of the lunar compositional asymmetry
Science Advances, 2022 The formation of the largest and most ancient lunar impact basin, South Pole–Aitken (SPA), was a defining event in the Moon’s evolution. Using numerical simulations, we show that widespread mantle heating from the SPA impact can catalyze the formation of the long-lived nearside-farside lunar asymmetry in incompatible elements and surface volcanic ...

Satellite Constellation Design for a Lunar Navigation and Communication System
Navigation, 2023 There has been a growing interest in using small satellites (SmallSats) for a future lunar navigation and communication satellite system (LNCSS). We conceptualize the design of a SmallSat-based LNCSS with Earth-global positioning system (GPS) time ...

The Control of the Lunar South Pole
, 2023 After the Apollo missions to the moon in 1969 and the 1970ies, the space research shifted to other goals. But since the 1990ies, the lunar research was restarted and intensified. Initially, the focus was on the development of science and technology for future moon missions.

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 ...

Image-Based Lunar Hazard Detection in Low Illumination Simulated Conditions via Vision Transformers
Sensors, 2023 Hazard detection is fundamental for a safe lunar landing. State-of-the-art autonomous lunar hazard detection relies on 2D image-based and 3D Lidar systems. The lunar south pole is challenging for vision-based methods.

A NEW REALIZATION OF THE GLOBAL LUNAR REFERENCE FRAME BASED ON CO-REGISTERED LOLA TRACKS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018 We present a method that aligns lunar south and north pole LOLA DTMs using selected LOLA tracks and co-registration techniques. The selected LOLA tracks were then co-registered to the aligned polar DTMs with the aim to create a new LOLA frame of high ...

Lunar south pole ice as heat sink for lunar cryofuel production system [PDF]
AIP Conference Proceedings, 1995 Recent Clementine bistatic radar data suggest that water ice may be present in a {open_quotes}forever shaded{close_quotes} depression or crater at the South Pole of the Moon. The ice is a feedstock for the electrolysis production of cryogenic oxygen and hydrogen rocket fuels for a transportation system on the moon and for leaving and descending on to ...
