Lunar 'Permafrost': Evidence for Widespread Water Ice on the Moon

ScienceDaily for October 22, 2010 reported on water ice on the Moon.

"The temperatures inside these permanently shadowed craters are even colder than we had expected," Paige said. "Our model results indicate that in these extreme cold conditions, surface deposits of water ice would almost certainly be stable; but perhaps more significantly, these areas are surrounded by much larger permafrost regions where ice could be stable just beneath the surface."
