In
craters near the south pole of the moon, NASA's Lunar Reconnaissance Orbiter found some bright areas and some very cold areas.
LRO's early results have already caused a stir: The Diviner Lunar Radiometer Experiment sent back the first global temperature maps of the moon, revealing ultracold pockets in permanently shadowed portions of
craters near the south pole.
Not exact matches
Equally enticing, some permanently shadowed
craters near the lunar
south pole seem to contain ice, which could provide water and air for the base.
The ice they carried would have vaporized from the impact, settling eventually in permanently shadowed
craters near the north and
south lunar
poles, where the extreme cold (below — 400 degrees Fahrenheit, according to recent observations) would have preserved it almost indefinitely.
Comparing these two images, it can be seen that the terrain
near the
south pole is more heavily
cratered while some of the region
near the north
pole shows less
cratered, smooth plains material, consistent with the general observations of the
poles made by Mariner 10.
