    Is the Past of Mars a Glimpse of our Future?

    The news were discussing some of Curiosity's recent findings. They reckon that the atmosphere may once have been many times thicker, but that the magnetic field surrounding Mars collapsed and most of the water/atmosphere was stripped from the planet. Anything that may have lived there 4 billion years ago wouldn't have had much chance.

    Which makes you wonder, if 2/3rds of Mars is thought to have once been ocean and now everything is a dusty red ball, would this be the future of Earth that we are looking at?

    probably not. From what i know mars lost its atmosphere due to its size. Its smaller so less gravity so lower escape velocity so atmosphere can "leak" away into space much easier than on earth. Again i believe that the earths magnetic field has at times been stronger/weaker/reversed polarity in the past as well

    Mix of both - the core of Mars has cooled and solidified, because it's a smaller body than Earth. This has caused the loss of the magnetosphere and that allowed the solar wind to strip away the atmosphere. The theory of it being littler with less gravity and the atmosphere drifting away because of this is not current, but was for a long time.
