TL;DR: Analytical analysis shows that the observed enhancement is localized to the permanently shadowed regions of the lunar south pole, and that observations of periodically solar-illuminated lunar surfaces, including the north pole, yielded no enhancement.

TL;DR: In the course of 71 days in lunar orbit, from 19 February to 3 May 1994, the Clementine spacecraft acquired just under two million digital images of the moon at visible and infrared wavelengths, enabling the global mapping of the rock types of the lunar crust and the first detailed investigation of the geology of the Lunar polar regions and the lunar far side.

TL;DR: The LRO Mini-RF utilizes new wideband hybrid polarization architecture to measure the Stokes parameters of the reflected signal, which can help to differentiate true volumetric ice reflections from false returns due to angular surface regolith.

TL;DR: The Mini-SAR as mentioned in this paper is a single frequency (S-band; 13-cm wavelength) Synthetic Aperture Radar (SAR) in a lightweight (~9 kg) package, which utilizes a unique hybrid polarization architecture, which allows determination of the Stokes parameters of the reflected signal, intended to distinguish volume scattering (caused by the presence of ice) from other scattering mechanisms (e.g. sub-wavelength scale surface roughness).

TL;DR: In 2008 two imaging radars will fly to the Moon to map the polar regions and search for ice as discussed by the authors, which would represent a significant potential resource for the manned human base that is to be set up at one of the Moon's poles late in the next decade.
