Lunar water research focuses on the discovery and study of water ice on the Moon. Water ice can be found in permanently shadowed craters near the lunar poles, where temperatures are low enough for the ice to persist. Scientists are interested in understanding the distribution, abundance, and origin of lunar water, as well as its potential uses for future human exploration and habitation of the Moon. This research area is important for advancing our understanding of the Moon's geology, history, and potential as a resource for future space missions.
