Lunar Samples Reveal Watery Secret

A new analysis of some very old rocks is reshaping our understanding of the moon. Scientists used modern techniques to search for tiny traces of hydrogen in a set of lunar sand samples taken by Apollo astronauts in the ’70s. The systems used in the study were able to break down the rocks 10 times more effectively than any past techniques. The find could lead to a deeper understanding of the moon’s formation and early years. Scientists have tried for decades to find signs of water on the moon but have long concluded it is dry.
