    Default Terraforming

    SciFi classic fare for a long time. Man talks of planetforming Mars, ice into oxygen, etc. Maybe not pie in the sky, after all we have been planetforming Earth for quite some time. Moving vast uantities of minerals from one place to another, storing enought warer in some places to give the planets attitude in spac a bit of a nudge.
    And then there's the atmosphere. We are certainly changing that and along with it raising ambient temperatures which melts pack ice which also changes the balance, andalters atmospheric and undersea currents.
    We have already rehearsed fot Mars…...

    Simpler is better, except when complicated looks really cool.

    I could imagine huge swings in biomes introducing and wiping out misc microbes and organisms before any kind of equilibrium happens. “seemed like a good idea” and the next thing you know you’ve got metal eating grubs and 2’ mosquitos chewing limbs off. We don’t have an adequate attention span for the job.

    I read a scientific article a while back that ( sadly for me ) threw cold water on the idea of massively terraforming Mars. Basically, in a nutshell, Mars doesn't have the mass to hold in place an atmosphere from being stripped away by solar wind.

    Isn’t that a trip, movies from Mars.
    This assembly of images and sounds from the Hyugens lander on Titan is a favorite.

    Despite the clean green image, my impression of New Zealand was that it's been terraformed for sheep, cattle, crop farming, and commercial timber.

    Mass isn't the problem, it's the magnetosphere, which Mars simply lacks. There's no fight with the Sun's might, there's only a deflection by a magnetic field. This task is performed differently by Earth and by Venus, but they both just kindly ask the particles to go somewhere else.
    Not surprisingly, Mars did have a magnetosphere during the period where we suspect it may have harbored life.

    What we do with Earth is as close to terraforming as a toddler in a china shop does pottery.

    Yes, we are making changes. But it's not terraforming by any means.
