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.

Uh, CowboyNeal, hydrogen gas for what?

You need three things for combustion. Fuel, got that. Ignition source, sure. Oxygen, don't got that. Maybe you could process it with the CO2 in the atmosphere to make hydrocarbons, oxygen, or even alcohol, (for the astronauts of course) but that would require energy to produce and there wouldn't be enough oxygen to fully combust any of those products. Hydrogen alone isn't good for much. Maybe if you sent a factory over used solar power to generate stuff (which was part of somebody's plan to get to Mars...) it could be useful, but just hydrogen has limited usefulness. I doubt it would be worth shipping back to earth to fuel the hydrogen economy either unless we're looking for hydrogen prices like $100 per cubic meter, cubic foot, mole, or whatever. Yeah, that'll work...

Re:Does it constitute life? Tough call

Doesn't matter; the fact that life was sustainable on two planets opens up the possibility to doubters that there could be life on more. The counter-anthropic principle states that we aren't special in the universe anyway, so if we find evidence to back it up, then there you go.
