Martian Crust Might Hold Much More Water SpaceDaily

The crust of the planet Mars may hold two to three times more water than scientists had previously believed. This finding is based on a study by Dr. Laurie A. Leshin of Arizona State University, comparing the amount of deuterium, an isotope of hydrogen, found in a meteorite of martian origin to the amount found in the martian atmosphere. Her report will be published in Geophysical Research Letters on July 15.
