Scientist Calls Mars a Terraforming Target

Raver32 writes "Mars will be transformed into a shirt-sleeve, habitable world for humanity before century's end, made livable by thawing out the coldish climes of the red planet and altering its now carbon dioxide-rich atmosphere. How best to carry out a fast-paced, decade by decade planetary face lift of Mars — a technique called "terraforming" — has been outlined by Lowell Wood, a noted physicist and recent retiree of the Lawrence Livermore National Laboratory and a long-time Visiting Fellow of the Hoover Institution. Lowell presented his eye-opening Mars manifesto at Flight School, held here June 20-22 at the Aspen Institute, laying out a scientific plan to "experiment on a planet we're not living on.""

    Mars will be transformed into a shirt-sleeve, habitable world for humanity before century's end, made livable by thawing out the coldish climes of the red planet and altering its now carbon dioxide-rich atmosphere.


    Mars doesn't have a carbon dioxide-rich atmosphere. Mars doesn't have an anything-rich atmosphere. Yes, what atmosphere Mars has is mostly CO2, but what atmosphere Mars has is actually a pretty decent approximation of vacuum; the thickest parts of it are barely 1% of typical atmospheric pressure on earth.

    The whole article doesn't actually include any specifics, it's just handwaving of the "and then a miracle occurs" sort:

    Overall, Wood said that a workable plan can be scripted to raise the average temperature of Mars, rid the world of excess carbon dioxide, as well as generate soil to support agriculture.


    Right. We'll get right on that. We only have 93 years to go, according to this article.

      What does that mean? Mars doesn't have enough gravity to hold enough gas at its current temperature. If we warm it up, that problem increases. You can't just wish that problem away. Mars doesn't need heat or oxygen to be Earth-like. Mars needs mass.

    2. why does venus get such short thrift? i'm thinking along the lines of energy investment and simple entropy: in my mind, to precipitate matter out of an atmosphere, and to dissipate heat, seems to be an easier task than accumulating atmospheric mass and stoking atmospheric heat. yes, even with runaway, geometric catalyst-driven processes, i think it is easier to destroy than it is to create. of course, to do this to venus will be excedingly difficult. but why do you think mars would be easier?

    but we should terraform mars and venus as soon as we can, regardless

    You really just don't get how hostile Mars actually is. On average, at the summit of Mt.

    The question is why should we mess up Mars, we're just barely starting on the road to fix the damage we've done to our own planet.

    Yes, I'd hate to ruin all that prinstine forest over there on the red planet.
    I couldn't care less about "ruining" currently lifeless worlds. Even if we found something similar to bacteria I wouldn't care if we went in there and "ruined" it by putting life on the same planet.
    Only worlds like Europa where there's a least the potential for some multi-cellular life as we know it would I proceed with caution.
    Life is special and we should put it everywhere we can. While potentially we might be messing with some Martian nano-scale bacteria and the like, the risks are far outweighed by the gains.

    Oh, and as far as "ruining" Earth goes. We are a product of the Earth. Humans are natural. We're life and evolved from the same process that gave us sharks and walnuts and horses. We're probably Earth's most precious resource because we're the lone form of life that can get to other planets, that can spread out beyond Earth. The Earth is far from ruined, it still supports trillons and trillons of individual life forms. And one form of life, us, is just getting capable of one of the greatest achievements possible. Spreading life out beyond the planet it formed on.

    Are you guys kidding me? You talk about terraforming as if it's just another trick we have in our arsenal, which it isn't. But, the technology aside, there are other issues that will trump that. For example, what about the militant lobby of folks who will undoubtedly make this into 'the evil humans rushing out to screw up another planet after they can't even keep a grip on their own?' You think Eco Terrorism is bad now, wait until someone starts moralizing on the idea of just commandeering a whole planet for experimental purposes. I personally think that it's as good of a laboratory as any, but I really think this would make the alarmist triply so. Think about it, what about property rights, mineral rights, and political philosophy, the interaction of religious idiots, and the mass media distortion... It's all just a huge cluster fsck waiting to happen, which is why I think it will never happen. I'd hope it does, but I don't see anything able to surmount those socio-political issues any time in the next couple of centuries, let alone the next 93 years.

    I'm all for eventually terraforming Mars once we've determined that there's no existing life there, but to do so before then would be a scientific loss on an unimaginable scale.

    Given that we're still discovering new species (microscopic ones by the gazillion, and still finding occasional large ones too) on earth, despite a huge exploratory effort that's been underway for hundreds of years, I think it's a bit early (massive understament) to think we've determined that mars is lacking any life at all

    I'm sure that something will develop that we just can't see yet. We've never terraformed a planet before so we're just going off on computer models which are never 100% accurate.

    Just say that we send a rocket ship that spews spores or whatever photosynthetic organism. There is a 70% survival rate, they get situated, some martian monsoon rips up a path and sends it up in the upper atmosphere where it rides the current for half a year where it mixes with some native vegetation and grows gangbusters. Density increases within 40 years - not part of the original model.

    Mars will never be habitable for us earthlings to live comfortably. Our bone density would suffer too with a year long round trip and 6 month minimum stay, that's 18 months away from Earth's gravity. Not too good for our health but we're smart enough to figure out a solution.

    Lets terraform that sucker and see what develops.
