Misleading mineral may have resulted in overestimate of water in moon

The amount of water present in the moon may have been overestimated by scientists studying the mineral apatite, researchers have discovered. For decades, scientists believed the moon was almost entirely devoid of water. However, the discovery of hydrogen-rich apatite within lunar rocks in 2010 seemed to hint at a more watery past. Scientists originally assumed that information obtained from a small sample of apatite could predict the original water content of a large body of magma, or even the entire moon, but a new study indicates that apatite may, in fact, be deceptive.
