Ice Detected Underneath Mars' North Pole

TheSync writes "A Reuters/Yahoo story says University of Arizona and Russian scientists have detected water ice uniformly distributed in the soil of Mars' north polar regions. The amount of hydrogen detected indicates ice of 80% to 90% of soil volume. Data was used from the Mars Global Surveyor and Mars Odyssey." It's worth noting that their study only detected large amounts of hydrogen; so much hydrogen that ice is figured to be the only form it could be in, although I kind of like the idea of Mars' pole covering a huge pocket of hydrogen gas.
