Martian Sea Discovered

mpesce writes "New Scientist is reporting that a large sea of frozen ice (between 800 and 900 km in size and 45 m deep) has been discovered by the ESA's Mars Express Probe. Here's the kicker: the sea of block ice is only five degrees away from the Martian equator. New Scientist also links to a PDF of a paper to be presented next month about the finding." Update: 02/21 15:30 GMT by T : Note: that's 45 meters deep, not 45 kilometers deep.

    I think we should use the moon as our garbage dump. Save Mars as a possible 2nd home when that big asteroid finally smashes into Earth and makes it uninhabitable for a few decades/centuries/eons.

    Funny how greenhouse gases are supposed to 'save' Mars and make it hospitable though, but are destroying our own planet. I guess that means I get to use my old aerosol hairspray and put leaded gasoline in my car, and use the old RJ-12 Freon when I eventually migrate to Mars.

    If we could terraform Mars, do you really think it would be hospitable? There's more to Earth than water and oxygen that makes it possible for life to live here. The moon, for instance, is just in the right position to affect our tides so they aren't out of control. And the magnetic field that helps move that nasty radiation around us... I wonder what it would mean for Earth if we terraformed Mars, changed it's magnetic field. It might even effect life here. I say we leave Mars alone before we kill ourselves.

      The thing is that when people mention terraforming a lot of people automatically assume the only goal that would be sufficient to be useful is to make it possible for humans to live entirely without any form of support.

      But even a minor increase in atmospheric pressure would have a massive impact on the feasability and safety of large domes, for instance, because it would even out the pressure difference between the outside and inside of a habitable dome.

      Just getting to a temperature and atmosphere where humans won't die instantly without a suit, or can work/survive outside in warm clothes and an oxygen mask will have a dramatic impact on how easy it will be to have a sustained presence, and the safety of a colony that would otherwise have to have massive safeguards against damages to habitats.

      Keep in mind that there are many areas on earth that are extremely inhospitable. While it would be great if Mars could once be as hospitable as the more pleasant areas of the earth, that doesn't mean that less won't still make it possible (or even interesting) to live there.

      Humans are quite resilient.

    Everyone knows that nature is static, and how things were 50, 100, or 1000 years ago are the way that they should be today, tomorrow, and forever!

    The reason why large scale or long-term changes to the environment are so risky is not, as you mistakenly state, that nature is static. Rather, it is that nature is highly dynamic on time scales spanning millennia and we don't understand the dynamics yet. A significant change that we think produces benefits may, in the long term, have devastating consequences.

    Once we understand natural systems sufficiently well to be able to predict the consequences of our actions in the long term, then we can engage in deliberate planet-wide engineering efforts, here on earth on on Mars. Until then, anything that alters our atmosphere, oceans, or ecology significantly is Russian roulette.

      Actually, we do know some of the consequences. Numerous human civilizations have been wiped out by self-inflicted ecological disaster. We know how sea levels have varied over time. We know of species that have disappeared because they inflicted ecological disaster on themselves (of course, they couldn't reason about their own behavior). And there are indications that global weather patterns can be pushed into various fairly stable states, some of which are highly unfavorable to human life and civilization.

      So, we know all sorts of bad things can happen. We don't know what effects our actions will have, but we do know that current conditions are pretty good for us, so we should avoid doing things that might change them until we know what we are doing.
