    Aren't we going to terraform Mars or Venus?

    Terraforming is a long-term project requiring technology significantly advanced over what we have today. Even terraforming advocates admit it would take a minimum of 200 years to modify Mars to the stage where even simple anaerobic microorganisms and algae can survive. [Ref: Terraforming: Engineering Planetary Environments, Martyn J. Fogg, SAE Press 1995.] Space habitats, on the other hand, can be built with today's technology, and would be homes in space which people initiating the program could move into within their lifetimes.

    Interstellar travel may someday become possible, but we have no guarantee that Earth-like planets will be as plentiful in the Milky Way galaxy as they have been in Hollywood, CA.

    What advantages would orbital settlements have over a colony built on another planet?

    1. Access to 24-hour-a-day sunlight. This makes solar power a consistent, economical energy source. Photovoltaic panels can convert sunlight into electrical current, and solar mirrors can concentrate it for process heat in industrial operations (such as the smelting of ore). A space-based solar concentrator the size of a football field (which could still weigh less than a car) could provide process heat equivalent to the burning of 1 million barrels of oil over 30 years.

      Sunlight also drives the life-support system of the habitat, so the day/night cycle can be set to whatever is convenient. Compare this to the moon, where there is 14 days of continuous daylight, and then a 14-day-long night. Here, some alternate energy source would probably have to be used half the time.
    2. Access to zero gravity. This may have a number of industrial and entertainment possibilities. Structures (such as the above-mentioned solar mirrors) could be built many times larger and flimsier in space than on a planet.

      Zero G would be a liability if there were no alternative to it. Astronauts experience loss of bone mass and muscle tone after prolonged exposure to weightlessness. But most of a space habitat would be under Earth-normal gravity, although there would be easy access to regions of reduced gravity and zero G (perhaps for personal flight). With planets, on the other hand, you have to take the gravity that's there, and it's often the wrong kind of gravity to keep us healthy. Lunarians or Martians would probably not be able to visit the Earth (nor accelerate at 1 G).
    3. Location near the top of Earth's gravity well. We here on Earth are the "gravitationally disadvantaged". We are at the bottom of a pit 6,400 km (4,000 miles) deep. This is what makes space launches from the surface so difficult and expensive. Settlers near the top of the gravity well would be ideally situated for departures to points beyond.
    4. Control of the environment. The weather and other aspects of the surroundings would be those of the inhabitants' choosing. Agriculture in space will benefit from weather control (fresh fruits and vegetables year-round!) and the absence of pests.
    5. Mobile territories. Although the first generation of space habitats will doubtless reside in High Earth Orbit, there's no reason why space settlers couldn't attach engines to their habitats, and over the course of months or years gradually change their orbit to whatever solar system location they found preferable.

Anything else would amount to a moratorium: you are NEVER completely sure that there is no niche somewhere on a planet where life (as we know it or not, jim!) exists. Infact, those planets that have the most potential to sustain (alien) life, will often be those that have the most potential to be fterraformed.

It's doubtfull that animal experiments can be totally abolished, and I have no problem with the necessary experiments, to ensure medicines are as safe as possible for human use. I think most would agree. This established one thing clearly: ultimately, humans come first (at least over non-sentient other beings).

    In practical terms, what does this imply? Well, science certainly must have it's shot, and the discovery of alien life would be wonderfull and potentially very important, even in our daily lives. But, if, say, in 20 years of searching, nothing is found, and one can be reasonably sure that there is no life (or it's in such remote niches that it will not rapidely be contaminated anyway), I think one should start terraforming the planet, so that humans (and the earth ecology to sustain them) may thrive on another planet, thereby augmenting our survival (and that of the earth ecology).

    If life IS found, however, things become more difficult. Certainly the timeframe in which to colonise/terraform would be much longer (if ever), depending on the level of alien ecological presence on the planet (small niches or not). Certainly, one could not let that alien life die, so, even if one did decide to terraform, then only after an artificial, viable surroundings is developped (sort of closed zoo, thus), where the alien ecology may be sustained indefinately.

    I'm not going into safety-concerns here, since that's another topic.

    But let's face it: when/if there are other alternatives in keeping alien (non-sentient) life in existence, then one should do that and go on with what is of most use to the human race anyway.

If the belief that environmentally sound activities involve compromise with people's other needs is so alien to you that you stick your fingers in your ears and go "La-la-la-la-la," then get out of my movement. That form of fundamentalism is out of touch with the experiences of most people in this world, even most environmentalists, and only serves to feed the stereotype of the lunatic fringe "greenie." A stereotype which has proven an effective weapon against us many times in the court of public opinion.

      And don't post annonymously if you believe in something. Have a spine.

    Terraforming other planets is fun, but first we really need to terraform Earth. Between desertification, global warming, overfishing, pollution, habitat destruction, slash&burn traditional farming, chemically-enhanced modern farming, genetic engineering of plants, moving species between ecological niches, sooting up the polar regions in ways that reduce the planet's albedo, and a lot of other things those pesky primates have been up to, this planet is becoming significantly less Earth-like. It's time to look at changing that. There have been a range of proposals to do things about it, from the Kyoto politics to Giant solar reflector shields in space to Bruce Sterling's Viridian Manifesto.

      We don't know nearly enough to accurately predict what would happen if we did something like put up a solar shade. By terraforming mars we can learn more about how to repair Earth, assuming we can bring the timescale down on such a project.

    Why is this even an issue?

    Personally, I'd like to see us gain the ability to create human-friendly environments away from Earth. But discussing the issue seems to me to be a pointless exercise, best left to university classrooms and NASA cafeterias during lunch hour.

    Why? Because we're not even remotely capable of actually doing any terraforming, for several reasons:

    1: We don't have the technological ability. We have some marginal sense of what might work, and lots of good ideas, but we're decades away from having the technological means to terraform.

    2: We don't have the economic ability to terraform. This is the real kicker. Assume that even a modest, trial attempt to terraform would cost $100 billion dollars; since we don't have even $1 billion to spend on it, we're at least a hundred orders of magnitude away from having the financial means to engage in even the most limited terraforming.

    3: We lack the political & social drive to engage in terraforming. Assuming (1) and (2) from above were no longer problems, there would need to be a strong, global, urgent demand that we engage in terraforming. There are many ways we might conceive of this happening, but none of them are apparently in the works, as of yet. This may change, but if it did, then we could spend time then debating the ethics of terraforming Mars, which, by then, will have been investigated to a much greater degree than it currently is.

    I figure we ought to be spending our money, time, and effort doing that investigation, rather than getting worked up over ethical debates that, ultimately, don't matter one whit.

    Yes, terraforming Mars is clearly the solution to all our problems.

    After all, if you have exceeded the credit limit on one credit card, it's not that your spending habits are out of line with your income, it's that you need another one, right?

    Folks, if we can't live well and sustainably on a planet as nice as Earth, adding Mars into the mix won't help.

    And if we can terraform an entire planet to save our species, I'd imagine we could save ourselves on our own planet without having to jump to another.

    Most all of the money we dump into this crap is a waste. And I'm not trying to be a troll. But seriously, we want to make Mars inhabitable. Why not start a little smaller there pancho. Like Africa.

    The problem with this.. besides it being probably completely impossible, is that before we ever started reaping any potential benefits of this experiment, we will immediately start taking this planet for granted. I don't know, that probably sounds like hippy stuff, but I think it's true.

    New worlds are not opened and settled by ethicists, moralists, or other contemplative types.

    Columbus, Pizzaro, Cortez, and others were interested in wealth, property and prestige.

    And they weren't worried about who or what was destroyed while they were acquiring those things.

    Despite this being /. I decided to perform a bit of research, so here are a few links to pages that I think support my point, that terraforming as far as a more hospitable atmosphere on Mars is possible:

    They may be wrong, I may be wrong, but simply claiming the fact that the current Martian atmosphere is very thin as proof that no sustainable atmosphere is possible on Mars, that does not cut it. I will grant you that a 99% earth-like biosphere is unlikely, but a lot less is needed for it to be of use to a colony. Even a slight increase in temperature and pressure would make it easier to live on Mars, some plants might be able to grow (genetically modified mountain plants), the domes (or whatever it might be) needed for habitation might have to handle a smaller difference in pressure, or the time an astronaut might survive in an accident might increase.

    And besides, even if it only lasts a few thousand years, an atmosphere might still prove useful. Not that I think we should do something like this without considering the consequenses, but once we have the technology, the trade-offs and risks might prove to be small enough for us to attempt terraforming Mars.
