A Wetter Moon Impacts Understanding of Lunar Origin, Paul Spdis, Air & Space
“A paper recently published in the Proceedings of the National Academy of Sciences describes lunar samples containing the calcium-phosphate mineral apatite. Using a sensitive technique, they detected water (in the form of its ion hydroxyl, -OH) within the crystal structure of this mineral. Moreover, these hydroxyl-bearing apatite grains are found in several different rocks from a variety of geological settings. This indicates that the presence of water in the lunar interior is not some fluke, but a general property of the Moon. So the story of water on the Moon advances.”
