Scientists’ understanding of the moon could be all wet. Its surface is surprisingly dewy and its interior contains more water than previous analyses of moon rocks have indicated, according to new studies.
Observations from three spacecraft suggest that water is widely distributed over a thin layer of the lunar surface rather than locked up in icy enclaves predicted to lie at the moon’s poles. The results, detailed in a trio of papers to be posted online September 24 in Science, suggest that l...
