Lunar south pole
The lunar south pole is of special interest to scientists because of the postulated occurrence of water ice in permanently shadowed areas around it. Of the lunar poles, the south pole is of greater interest because the area that remains in shadow is much larger than that at the north pole. The lunar south pole craters are unique in that sunlight does not reach the bottom. Such craters are cold traps that contain a fossil record of the early solar system.
Craters
The rotational axis of the Moon lies within Shackleton Crater. Notable craters nearest to the lunar south pole include De Gerlache, Sverdrup, Shoemaker, Faustini, Haworth, Nobile and Cabeus.
Exploration
Spacecraft from several countries have explored the region around the lunar south pole. Extensive studies were conducted by the Lunar Orbiter, Clementine, Lunar Prospector, Lunar Reconnaissance Orbiter, Kaguya, and Chandrayaan. NASA's LCROSS mission found a significant amount of water in Cabeus.
Future
Future planned exploration of the Lunar south polar region includes a private mission by Shackleton Energy Company, no earlier than 2016. Shackleton intends to land a robotic precursor exploration rover to "identify and characterize the nature, composition and locations of the optimum ice concentrations at the north and Lunar south pole craters".
