At the South Pole of the Moon, no matter where the sun turns, some craters are located.

In the moon’s Antarctic, no matter where the sun turns, the bottom of some craters is always in shadow. These permanently shaded belts are likely to contain water ice, which may be an important source of water for future human bases on the Moon. This is one of the reasons why many countries, such as India and the United States, have begun to explore the South Pole of the Moon. Video Source: Nick Stevens GraphicsSteed’s Weibo Video of the Neck
