Elliptical structure of the lunar South Pole-Aitken basin

Icarus, 2009
Abstract The South Pole-Aitken basin (SP-A) is the largest and oldest basin on the Moon. The basin has usually been interpreted to exhibit a degraded circular structure, but here we demonstrate that the topography, iron and thorium signatures of the basin are well described by ellipses with axes measuring 2400 by 2050 km and centered at −53°, 191°E ...

Distribution and anomaly of microwave emission at Lunar South Pole

Science China Earth Sciences, 2009
Investigation on Lunar polar area is almost every lunar mission’s primary objective in recent years. The rationale behind it is that illumination and ice resources in this area can be potentially very helpful for constructing lunar human base. In this paper, we analyze microwave radiometric characteristics of the Moon by using the newly acquired Chang ...

Lack of Exposed Ice Inside Lunar South Pole Shackleton Crater

Science, 2008
The inside of Shackleton Crater at the lunar south pole is permanently shadowed; it has been inferred to hold water-ice deposits. The Terrain Camera (TC), a 10-meter-resolution stereo camera onboard the Selenological and Engineering Explorer (SELENE) spacecraft, succeeded in imaging the inside of the crater, which was faintly lit by sunlight scattered ...

A concept for a simple radio observatory at the lunar south pole

Advances in Space Research, 2003
Abstract The lunar south pole may be the most feasible site for the first very low frequency interferometric array. The part of the electromagnetic spectrum below ∼30 MHz remains to be the only unexplored window in astronomy because of significant radio interference of Earth.

Effects of the South Pole-Aitken Magnetic Anomaly Cluster on the Plasma Environment at the Lunar South Pole

Despite lacking a global magnetic field, the Moon features localized magnetized regions called lunar magnetic anomalies [1]. Their interaction with the solar wind results in significant proton reflection and deflection [2], creating unique structures often referred to as lunar mini-magnetospheres [3, 4].

Acquisition and tracking for communications between Lunar South Pole and Earth

2019 IEEE Aerospace Conference, 2019
In this paper we design and analyze an end-to-end communication system between a lander/rover on the surface of the lunar South Pole and an Earth station. The acquisition and tracking system is discussed in detail. The communication system on the lander or rover could be used for the Earth-to-Moon communication.

Magnetic Anomalies Near the Lunar South Pole and Their Consequences 

We report improved mapping of crustal magnetic anomalies near the lunar poles using a combination of Lunar Prospector and Kaguya orbital magnetometer data.  In agreement with previous results, a concentration of moderately strong magnetic anomalies is centered approximately on the south polar region.

EuroMoon 2000 A plan for a European Lunar South Pole Expedition

Acta Astronautica, 1997
Abstract EuroMoon 2000 is an initiative by ESA and European Space industry to mark the progress of European space activities into the new millennium. The objective is to land a spacecraft at a continuously sunlit point on the rim of the lunar South Pole crater.
