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.

      The Inuit population there refer to water as "molten ice", because ice is the most common state.

      Were as we southerners (south of the arctic circle) consider ice as frozen water.

      I don't think there is liquid magma, since all the papers and articles from probes that I've read have never said anything about significant activity like earthquakes (Marsquakes?). Also, the lack of a substantial mangnetic field suggests a solid core (Venus, on the other hand, lacks a magnetic field because it's rotational rate is so slow). Venus also shows signs of relatively recent and catastrophic volcanic activity. It's atmostphere is volcanic, it has very few craters on its surface, and those that are there are young and well-defined. It doesn't have older partially eroded craters, but there are a few partially covered in lava flows or with their rims still protruding above lava fields. The youngest Martian lava flows are older and smaller, suggesting not only a lack of recent activity, but a decline in activity before it stopped. Anyway, like you said, this IS, nonetheless, probably our best bet for finding existing life, or signs of past life. It doesn't neccessarily take heat for life to survive, although life in every form we've encountered thus far (Not that we really have an abundance of data to go on) at least required heat to start, which Mars once had just as much as Earth. Near the equator, it's not that cold. The conditions in those ice packs may be no worse than some arctic conditions on Earth. Life probably couldn't form there, but it could certainly survive there.

    I assume they said that because the article states that any water that close to the equator should have melted by now, unless it was covered by some insulating material such as volcanic ash.

    However there is an advantage to finding ice near the equator. If we wish to launch spacecraft from Mars the equator would be the best launching point, for the same reason we launch spacecraft from Earth as close to the equator as possible.

    The water could be a potential source of fuel, thus it (assuming it is water) lying close to the equator would be advantageous for that reason.

    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.
