Chinese team finds first trace of lunar water, a big step towards understanding the moon


Scientists find hydrated mineral ‘enriched’ with molecular water based on soil samples returned by Chang’e-5 mission in 2020.

Samples brought back by American Apollo astronauts decades ago revealed no sign of water and led scientists to conclude that lunar soil must be completely dry, according to Nasa. In recent years, the dry moon concept has been challenged thanks to technological advances, such as microanalysis techniques and remote sensing, according to the Nature Astronomy paper. In 2009, for example, the Indian Space Research Organisation’s Chandrayaan-1 spacecraft detected signs of hydrated minerals in the form of oxygen and hydrogen molecules in sunlit areas of the moon.
