NASA Probes Reveal Vast Stores of Martian Ice

John Faughnan writes: "The BBC reports that a British newspaper has leaked stunning news from the Mars Odyssey spacecraft. Vast amounts of water ice are present on mars, "[if it] were to melt it could cover the planet in an ocean at least 500 metres deep." Researchers thought it would take a year to detect any water ice below the martian surface, but the huge quantity meant that weeks of observation were sufficient. The BBC notes that "The Mars Polar Lander was to touch down in exactly the right spot in 1999 and would have undoubtedly detected the ice had it not malfunctioned on the way down." This discovery will change plans for upcoming probes and may lead to a manned mission within the next two decades. The official announcement was scheduled for this Thursday prior to several publications."

    Not just terraforming, but this makes a manned mission truly feasible. With huge stores of water available, we won't need to waste energy on moving as much. This means a manned Mars mission could be much cheaper.

  2. 500 meters? How? by boa13 · · Score: 4, Interesting

    Has anyone actually looked at a Mars map? I'm running the latest version of the Mars Simulation Project, looking at the planet in topography mode.

    This planet has altitudes ranging from approximately -8000 meters to +22000 meters, with two very distinctive zones: around -100 W, mostly on the southern hemisphere, there is a huge, +5000 meters continent; the northern hemisphere is between -5000 and 0 meters; and there is a very impressive hole centered at 70 E and 40 S, between -7000 and -5000 meters, sourrounded by a 0 to 5000 meters zone - what happened there? A huge spacial hit?

    Anyway, saying Mars would be covered by 500 meters of water is completely meaningless. I guess they took the quantity of water and divided it by the surface of Mars. They mostly want to impress people, I guess, but I for one would be more impressed if someone came with a new Mars map showing the areas where the "sea" would be once the ice was melted. There is an illustration there, but of course it doesn't take into account the "real" quantity of ice/water.

  3. Less sand storms by Midnight+Thunder · · Score: 4, Interesting

    One other thing that should be noted is that if the water is ever leaked to the surface, along with an increase in heat via CO2 being pumped into the atmosphee, then there will probably be a reduction in the amount of dust in the atmosphere, as the iron binds to water droplets. This would modify the atmospheric conditions and probably reduce the number of violent storms. Also, a humid atmosphere would probably also make it more favourable to life, if there isn't any already there.

    Without water it would be much more difficult to teraform the planet.

    This is unresearched, but I believe that it is a probable scenario, based on the knowledge I have.
