Image of the Moon taken by the Moon Mineralogy Mapper. Blue shows the spectral signature of water. Distribution of water ice present in the upper meter of the Martian surface for lower (top) and higher (bottom) latitudes . The percentages are derived through stoichiometric calculations based on epithermal neutron fluxes. These fluxes were detected by the Neutron Spectrometer aboard the 2001 Mars Odyssey spacecraft.
