    Rather interesting order this article puts the reasons in...

    'to work' is not a real reason to go to space, instead, the article really shold have focused on a) the abundant energy and raw materials available in space, and b) the nearly infinitely-customizable work environments abailable in space. At any rate, this is only a secondary reason.

    'to live'? Exactly what sort of reason is this? Sure, life is important (of course I think that...I'm a living being...I can't help it), but does that mean it's our manifest destiny to spread life throughout the universe, merely for the sake of spreading life? Again, this reason, although important, is purely secondary.

    'to survive'. Finally we come to the heart of the matter...the reason that should have been number one, with the two reasons listed above in support of it. Humankind must colonize space, and do it soon. Between the dwindling rescources available to us while we remain shackled to a gravity well, and the impending mass-extinction events (asteroid, pandemic, super-volcano...take your pick), we are left with very little time in which to secure our species' future. Establishing a viable space-community should be the primary goal of the human race.

    (BTW, more interesting information regarding our continued survival can be found here [thepreparation.com].)

      "the reason that should have been number one"

      It is.

      Althought space colonization is a good thing IMO, we're currently bogged down in crap down here. It's time for humans to just get more intelligent about things, from war to drugs to hunger, instead of listening to one person, taking that opinion as their own, and sticking to it for all eternity. The last thing we need is another colony that works the same as Earth, it'd be a little self-defeating after awhile.

        Actually it may help us to move beyond our problems here. If a group were to go forth and colonize away from the general body, it may allow for different philosophy to take hold. Not to mention with the harsh realities of survival in space, it might force a little practicality on the population, one would hope, no one would care about little things like sexual preference when the regular meteor shower may destroy the living environment and everyone is needed to repair it.

        The funny part of this is that people often think we'll escape what they don't like about society here, by just leaving.

        If your opinions aren't properly represented on earth, what makes you think it will be any different just because you're in space? I think we ought to work on making earth a nice place, THEN worry about how well we can manage ourselves in space colonies.

        Living in space won't make you happy and free. Learning to make a difference here will.

      The article was not about why crap in general should be in space.

      It was in fact about the top reasons for humans in space.

      In fact, having humans in space is not a necessary condition for gathering "abundant energy and raw materials" of other planets. The article just makes the arguments that humans would be better suited than robots to work in space.

      In general, the article seemed a bit fluffy. For example, the robot versus people argument didn't mention that sending up a robot to do a specific task is often one or two orders of magnitude cheaper than people. Robotic capabilities keep getting better while plain old non-genetically modified humans remain the same.

      I'm not sure that people must colonize space immediately. For me, it's like playing those old sim games. Do you spend limited research dollars on building 1960's style moon bases, or keep pressing on and shooting for nanotech before you move off the planet? If you can hold on long enough before colonization, you can move far more people and reach self-sufficiency much sooner.

      Interesting point you make, but alas, it may be life that people say is precious. However, the one singulare reason why we as humans are not making space colonisation a top priority is money and greed. If one looks into the past for an answer as to why we are not colonizing space at this point it is simple.. We have not been given the old 'kick in the pants yet' ... I will wager that the INSTANT we get hit with an asteroid that doesnt totally anihilate us, you will see some serious money put into colonising space. Until then procrastination will be king..

          Hasn't it occurred to anyone that funding a multi-trillion dollar effort to colonize space, with its massive consumption of energy and resources, might push us over the edge and to the very extinction which space fanboys claim to be staving off?

          Yes, I did, right after I read one of Douglas Adams' books in which it was related that an entire empire was lost due to an unsanitized telephone.

          Then I came to my senses.

          Has it occurred to you that the advances in technology made during the space race benefited all humanity? Granted there are still people squatting in the mud building houses out of sticks and straw and mostly going hungry, but those people were doing that BEFORE space travel. Now, they occasionally get someone bringing them some medication, sometimes some food - and the shit is wrapped in space-age (and later) plastics. I don't want to get off on a rant here, so I guess I'll just stop soon, but have you considered that if there is always going to be this great a disparity, the answer is to provide enough wealth so that everyone can actually have some?

          Developing space is highly desirable because it's not hazardous to people living on Earth. Whatever you say about Earth's climate, and the materials lying around on or near its surface, Humans are making it worse in both regards. Even if it's only a tiny nod of the head compared to natural processes, why do we want to do that to ourselves? Putting a lot of our infrastructure in orbit (food and energy production for example, as well as heavy manufacturing, refining, blah blah blah) would allow us to increase production and decrease pollution. Having people up there is sort of a necessary part of building it all, putting it in place, and maintaining it. For some types of problems, you really need a human at this point.

          Starting sooner rather than later means that we will proceed faster. The faster we improve our level of technology the more rapidly the lower levels of technology will reach more people, allowing them to crawl up out of the mud, take a shower, and go to work, feed their family, et cetera. Personally I'm merely hoping that somewhere in the world, these people end up building a society that's not predicated upon taking advantage of the weaknesses of the citizenry.

For example, to colonise Mars, we'll have to create an oxygen/nitrogen atmosphere for breathing, add rivers and seas for water, grow fields and farmlands for food, and trees for recycling bits of the atmosphere. With these, there won't be many differences from Earth, so our survival on such a planet should be pretty easy.

      If there was an Extinction Level Event on Earth and we had a substantial number of persons else where, then we would have a greater chance of the Human Race surviving. Granted with todays tech we cannot create a viable colony on another planet or in orbit, but all things were started with a small step (America didnt suddenly become 'colonised' by Europeans, it took a small shipload of people to find it, then a few people to go there and live and gradually it built up. Small steps gradually getting bigger). If we dont start small now, we cant continue bigger later.

      Be that as it may, currently we need only planet-breaking disaster for 100% guaranteed extinction. The odds of such a disaster are low, but they are nonzero.

      Although the chances of survival on a completely new planet may be significantly lower than our chances of survival on earth, overall the idea of interplanetary colonization lowers the chances of total human extinction.

      So "chances are worse elsewhere" still translates to "overall chances are better." You're applying faulty reasoning to the problem.

      However, while all of us dream of populating other planets, the practicality of doing so with today's technology is absurd. For example, we haven't colonized Antartica. Sure there are a few scientists living on isolated stations, but they are doing research - no intention of making the area habitable. If we can't even colonize all of the continents here on Earth, why bother with other planets. A better example is the bottom of the ocean. Why not colonize the ocean floor? It's less rediculous than colonizing the moon.

      On this survival front, no scientist could possibly prove that life is safier anywhere else than on the Earth, where it has been happily plodding along for a few billion years, and so far been unobserved anywhere else.

      I want to elaborate on this. I am quite convinced that the survival argument for space travel is fundamentally an excuse used by people whose real reasons are less rational. How else could such a patently nonsensical argument have gained such passionate support among a community of otherwise intelligent and rational people?

      The counterargument is as follows: what could anybody or anything possibly do to our planet to make it as hostile an environment as, say, Mars?

      Even nuclear war or an asteroid strike would be unlikely to eliminate the oxygen from the atmosphere or change the mean surface temperature by more than, say, 20 or 30 degrees Celsius. Still quite hospitable in the grand scheme of things.

      Rather than shipping a self sufficient colony of humans to Mars, at extraordinary difficulty, expense, and risk, why not just build the same colony in a physically and environmentally isolated place on Earth, like some mine shaft somewhere? Heck, build two for redundancy. The engineering and political risk to such a project would be vastly reduced by avoiding the need to shlep everything between gravity wells. Space travel is extraordinary difficult, and as a result, space engineering projects have a remarkably poor success rate. The survival of the species hardly seems like an area where we should choose to take on vast and unnecessary risks.

      If our goal were truly to protect the survival of the species, we would start with that premise and consider the technical merits of all the possible solutions. Yet we seem to be entering this debate with a preconception that space colonization is the answer. I believe that the answer is preordained simply because survival of the species never was a goal, and never will be; it is simply a rationalization for our desire to explore a new frontier!

      I think nothing illustrates this better than the political absurdity of actually implementing a realistic human survival plan here on Earth. Can you imagine getting Congress to spend a few billion dollars for a self sufficient colony on Earth? It would be laughed out of committee. Even at the height of the Cold War, we were telling schoolchildren to hide under their desks instead of seriously trying to protect our future. And just writing these words, I am starting to sound like a survivalist crackpot!

      Why is it so much easier for us to justify an enormously difficult, expensive, and failure prone attempt at survivalism in space when we do it so much better, faster, and cheaper here on Earth?

    Damn Formating

    This article entierly misses the point. No one argues that humans should not eventually go to space for these reasons and many more. The question is whether it makes sense to send people into space now.

    In particular the question boils down to whether the money spend on human space flight now would be better spent on general technological advancement and not wasted on giant solid rocket boosters. This general technilogical advancement would then reduce the cost and increase the utility of going to space. This would be a plan to ultimately colonize space faster in the long run and in no way contradicts the arguments in the article.

    In short the question is whether we are ready for human space flight or if we should spend more of our resources laying groundwork. I mean I think we all agree that in the 1950's it would have been a mistake to just try and build a really big v2 and do space exploration in that fasion. Instead we needed to do lots more research and build tools. Perhaps we need to build better launch systems, robotic support systems, life support systems and the like before it really makes sense for humans to be in space.

    In particular at the moment it is not economically effective to send humans to space for raw materials. Thus at the moment argument 1 doesn't really apply yet. Also we don't have the technology to establish independent colonies. If the earth was hit with a disaster any space colonies we had now would die without support. This means argument 3 doesn't really apply yet. Finally argument 2 is a good general goal but it has no time component. Sure lets put life in space but lets spend our money now on technology and later use that to more effectively put life in space.

    (Yes I admit that human space flight has some spin offs. However, my claim is that these spin offs are not really worth the large price compared to other research opportunities like robots or ground based research)

      The reason we need to put a few people into space now is quite simple: the only way to determine the long term health effects of living in space is to have people living in space! We need to start the long-term research now, so we can better design life support systems for the time in the future when it makes more sense to send people into space.

    This whole article sounds exactly like it is introduced: Something that will sound good to president Bush, who has already made up his mind (feel free to mod down).

    Still, the author does put a nice economic sounding spin to his argument.

    Risk management catchphrases:

    "Don't put all your eggs in one basket", "diversify your portfolio", "spread your risk",

    Supply and demand:

    The most valuable part of the universe is life: not only because life is important, but because life appears to be extremely rare.

    This all sounds well and good but I think the author might give "cost-effectiveness" a look.

    Cost-effectiveness [wikipedia.org] is "a comparison between the relative expenditure (costs) and outcome (effects) associated with two or more courses of outcome."

    The US administration contends that the Koyoto agreement is too costly to implement. How about increasing the value of our current investment (earth) by decreasing the probability that something might go wrong (global warming).

    Surely it is more cost-effective to limit Co2 emissions that to burn away and aim for Mars in 2030?

    Also, if life is so valuble due to its rarity, why jump the gun and send astronauts out to do what robots can do just as well (and they can for now)? Investing in artificial intelligence has a higher probability of returning an eventual profit that investing in life support. We're more likely to be able to use AI in various indurstries than we are of making earth inhabitable in the near future.

    When we've got the AI technology right, we'll send robots out to colonize and will therefore have to do less research into life support.

    I kid you not, I wrote this on my whiteboard at work for all to see:
    Dinosaurs are extinct because they didn't have a space program.

    Slight oversimplification, but the idea is there.

    Oh and by the way, IAARS (I am a rocket scientist).

    I heard Peter Ward and Don Brownlee pumping their book a couple of years ago on National Public Radio's Science Friday [sciencefriday.com]. They propose that NO life will be possible in approximately 500 million year due to the life cyle of the Sun. I only heard the last few minutes of their explanation, but they contend that the organic molecules that life depends on here on Earth will not form under the intense ultraviolet radiation that will be pumped from Sol in a half-billion years. No organic molecules, no life.

    Okay so what if they are wrong? If Sol takes the normal life course of any star it will expand and consume the inner terristrial planets, Earth included. That scenario can only be avoided by the only other option stars take: a nova and possible core collapse. That isn't exactly a path that leads to expansion of organic life either.

    So we either move out into space or die out as a life form. Humans might not (probably not) exist in those timeframes, but organic life will have to move to survive.

    OK, maybe my thoughts on this matter are a bit simplistic, but if you consider the Malthusian Catastrophe [wikipedia.org] (sometimes known as the Malthusian Dilemma), it boils down to two things:

    1. Our planet has limited resources
    2. We're using them

    While, in theory, some would argue we should adopt economies based upon sustainability rather than growth, I think it's more realistic to say that this will only happen when we have no choice. In the meantime, in our never-ending quest for resources, we can look at those two bullet points and notice that the real limiting factor isn't "resources", but "our planet."

    I certainly don't believe we can solve our population problems via space exploration, nor do I think it's likely we're soon going to be in a position to utilize enough space-based resources to make a difference at the bottom of our gravity well. However, we can still spread the human race further and increase our chances of survival (as mentioned in the article) by ensuring that some humans are not dependent on our planet's resources.

    But as a last ditch effort to sway those Harvard business school types who really don't understand the long-term benefits we get from space exploration, here's a short list of technologies have been directly a direct result or space research or greatly enhanced by said research:

    • Air quality monitors used in smokestacks
    • Better structural analysis technologies
    • Energy efficient insulation
    • Freeze-dried food
    • Machinery lubricants
    • Many new medical techniques
    • New hydroponics techniques
    • Scratch resistant lenses
    • Semiconductors
    • Smoke detectors
    • Solar energy
    • Water purification systems
    • Weather forecasting
    • And many more ...

    I've ranted a bit more about this in one of my journals [livejournal.com].

    Just think - with overpopulation and limited resources, moving out into space solves all our problems for FREE!

    Oh wait - no it doesn't. Say we even manage to get 1% of the earths population out there off the earth. We'll quickly replace that number on earth alone, despite all the effort (and vast resources) being put forth to sustain the colonies that are to be created off-world. Now we have even fewer resources, for still more population. We'll still be providing the resources for that off-world population (plus a big load of technology) for years to come, easily a few generations, before they can become reasonably self-sufficient.

    Even when that point comes, we'll just be back where we started - humans ruining other moons or planets.

    Maybe we should get our shit together at home before we spread forth, otherwise we're the same as all of those 'evil aliens' in all our movies that come to steal the earths resources. Didn't you ever wonder why that was such a common plot point?

    If we don't, we're just a virus and a plague on this galaxy.

    1. Unlimited energy
    2. Unlimited raw materials

    That seems to me to be such a greater proposition than "to work" or "to live". Imagine tne entire world entering an economic prosperity that doesn't end for fifty thousand years... That's think kind of thing you get by utilizing the resources of our solar systel, let alone outer space.

    Similar to the ships designed in space postulated by Clarke, but with robots and solar/nuclear hybrid power - we launch an entire fleet of them towards all the stars in our galaxy likely to have Class M (sorry for the Trek ref) planets - and embryos frozen.

    There is no reasonable cryogenic method to take a human form and shut it down for millions of years. But it's feasible with frozen embryos.

    How we grow them from there, I don't know. We'd some way to create test tube babies without implanting them in a host.

    The adam and eve of the new solar system are created. If it turns out there is habitable planet in that system - they win. If there isn't, the humans can nuke themselves or something.

    I don't know - seems the only way. The distances are just so huge and the time scales so vast, that transporting organic material that far seems impractical.

It's a naive, domestic operating system without any breeding, but I think you'll be amused by its presumption.
