  •  If Mars was once more habitable, should we (0+ / 0-)

    not be looking to Venus as the next place for its future habitable potential, given the expanding universe and all?

    •  No. Nonono. Not with the vulcanism, lack thereof. (8+ / 0-)

      Even if it didn't kill any probe sent there, even if the atmosphere wasn't poison, even if the available water wasn't superheated steam... that whole-surface-upheaval haven't-had-a-volcano-since theory to explain why the ENTIRE FREAKING CRUST appears to all be the same age would make it not a good place to consider colonizing.

      Think building a colony on top of the Yellowstone supervolcano, only it's the entire damn planet and you don't know if it just went off the once or what the dang reload time is.

      Prayers and best wishes to those in Japan.

      •  People do insane things all the time. (0+ / 0-)

        It doesn't matter how insane an idea is.  If it can be technically accomplished, someone will do it.  Although I do agree that a 'colony' will probably never be feasible.

        That doesn't rule out the possibility that a living area on Venus could be technically accomplished one day.  Although that hurdle is so great that it's almost pointless to speculate.

        I imagine a Survivor analog, only the contestants have inane tasks to complete on Venus, instead of inane tasks to complete in Hawaii.

        That is almost inevitable (if the technical problems will ever be overcome).  We're very innovative when it comes to inanity.

      •  Can you imagine how toxic the soil is too? (4+ / 0-)

        After being soaked in sulphuric acid for a billion years? Worse than New Jersey!! (hey, I kid because I love!)

      •  Atomosphere in addition to being poisionous (2+ / 0-)

        is thick enough to crush anything with the air pressure (including probes in minutes).

    •  Mars is probably our best bet (2+ / 0-)

      for a habitable planet other than Earth, in our solar system. Much more habitable than Venus.

      •  I still say Ceres, if the theorized water is there (1+ / 0-)
        Recommended by:

        It's still large enough to have gravity, all that water to use as water, air, and rocket fuel, and much easier to land on and take off of because of it's smaller gravity well.

      •  My best guess in the habitable rock category (2+ / 0-)
        Recommended by:
        Paul Rogers, wu ming

        would be Europa if we're right about the water ocean under an ice crust. That'd give the possibility of oceanic smoker style biology islands, since something is going on under there enough to make the crust move and crack.

        Planet proper, Mars.

        Prayers and best wishes to those in Japan.

        •  Europa is right in the Jupiter radiation belt (6+ / 0-)

          Which is very intense, so it would be REALLY bad, if not impossible, for humans to travel to. Then there's also the distance problem, Jupiter is a long ways away - if you're going to go that far, better to go out to Saturn that doesn't have the radiation problem, and use Enceledus.

        •  There is kind of a lack of actual land (0+ / 0-)

          on Europa. I guess any realistic assesment of Mars would include Domes, so I guess the could float on Europa.

          But at least Mars has actual sunlight. Europa is far enough out the sun is pretty dim. Kind of a depressing habitat for humanity, floating under freezing water, no natural light.

          I think we're not sure how the human physiology will adjust to less gravity. Mars is less, Europa less still.

          And Mars, theoretically could be terraformed as colonists live under protection. Meaning in 10,000 years it may be more hospitable.

          I am in a agreement if there is vulcanic heat under the ice crust on Europa, it may hold life.
