The Top Three Reasons for Humans in Space
An anonymous reader writes "Why humans in space? The Space Review has the top three reasons: 3. To work. 2. To live. 1. To survive. 'To work' means doing stuff in space: research, explore, visit, etc. 'To live' means to have humans/life beyond Earth in colonies/settlements. 'To survive' means that putting humans/life beyond Earth is a very Good Thing in case a very Bad Thing happens to humans/life on Earth."
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.)

Yes, you too can mutate beyond your wildest dreams, slice-n-dice your DNA and see what progeny you yield! Two heads? Three arms? Oh, no! That's fine for the Beeblebrox's next door over, but you could have any of the following with proper exposure to unshielded solar radation:

If we can't survive here on Earth, our chances somewhere else are worse.

Instead of pushing outward in it's exploration ventures, NASA should push inward and delve deep into Earth's oceans. There's a lot of possibilites for research and discovery right in our "big backyard bathtub" if only we'd take the plunge.
Mission costs would be lower, and I really believe the payoff would be much, much greater!

Why store data at multiple locations? Disks can be destroyed in a fire at all locations after all. It's called redundancy, and it works with living beings too. If humans are on multiple planets the race will survive one being destroyed.
The glorious potential of space porn!
its true, any problems they try to escape will just follow us, its human nature. They probably thought that moving to North America would solve the problems they were having in the old world, they just followed us, and everyone developed new problems to deal with anyway
- My question is: Can Slashdot be Slashdotted? -
In the heart of any exploration, any advance of human genius, there was always some personal itch needed to be scratched.
"oh, we can get to India faster" or "oh, we can fly mail to South America in 3 days" or "oh, we can throw explosives further", all this comes later as part of the speech aimed at the venture capitalists, etc. The foundation, the basic desire is always just because it is there. The practical needs come later.
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.
It's a perfectly valid point! Everybody wants to "Space", but unless there's money to be made, the Big Men With Dollars aren't going to look in your direction. Which means you either need to talk the government into it - hard enough in good times - or you need an angel investor.
Whichever way you look at it, whichever way it works, finding the mysterious #2 in this case IS our best case to getting into space. Space tourism is risky and expensive, but it's only a start. If we could come up with some good, financial, bottom-line-friendly reasons to get into space, we could get some serious money - and effort - behind it.

Think a little bigger. If a really really big meteor hits the Earth, we're screwed. The likelyhood that 2 planet-killer meteors will devastate 2 planets that we have colonies within a relatively short amount of time (20 years) is extremely less likely.
Also, your examples of polution, population, and nuclear explosion don't make much sense either. Polution is far less likely on another planet, since fossil fuels are far less likely. We'd probably be using solar or nuclear power instead.
Population makes the least sense, since expanding to other planets is the single most effective way of dealing with this issue. You effectively double your space and eliminate population issues.
Nuclear explosion isn't really a factor either. If you're talking weapons, the likelyhood of them being taken to upstart colonies isn't too likely. Once the colony is established, if one location (Earth or the colony) wipes itself out with nukes, the other is going to think long and hard before using theirs. Having a front-row seat to devastation makes people do everything they can to avoid it happening again (see 9/11 attacks for proof). If you're talking about nuclear power plants, they're getting safer and safer, so I doubt it would be an issue. Besides, nuclear meltdown is a local issue, not a planetary issue.

Assuming that you're correct and man cannot damage the earth to the point of it being uninhabitable, there are certainly plenty of other ways for us to not survive here that the article specifically mentions
Not the least of which is self-annihilation by nuclear or biological weapons (which have proven that they are ready and capable of killing many of us very quickly). The article also mentions natural disasters, which (once again) have proven themselves able to wipe out huge portions of the earth.
We are also aware of certain natural disasters that might be able to wipe out ALL LIFE on this planet pretty much within a day. I won't bother naming any because most educated people should be able to come up with at least 3 good ones, including as least one inevitability.
That kind of argument can potentially keep humans out of space forever. Theoretically, there will always be superior technology on the horizon, and if we always decide to wait for it, then we'll never get anywhere.
Also, there is the distinct possibility that the decision for humans to travel to space would actually act as a catalyst for innovation. After all, necessity is the mother of invention.
Mens et Manus
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)
If you liked this thought maybe you would find my blog nice too:
I must disagree.
When Europeans moved to North America, they did solve some real problems. Granted, we still have problems, but they are different than the ones Europeans had circa 1000 A.D. It's a fairly trivial exercise to show things are much better now.
OK, what can moving into space do for humanity? First, there is the not putting all our eggs in one basket factor. Secondly, we can try new things. Some of our experiments will succeed; some will fail. Successful experiments can be emulated. Our failures can teach us what not to do.
Starting back in the 17th century, the part of North America governed by first England and now the United States and Canada tried doing some new things with regard to government and society. These experiments proved so successful that parent societies in Europe adopted many of the new ideas first tried in North America.
We haven't acheived any sort of utopia, but we have made significant progress.

Still, the author does put a nice economic sounding spin to his argument.
Risk management catchphrases:
Supply and demand:
This all sounds well and good but I think the author might give "cost-effectiveness" a look.
Cost-effectiveness 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.

The problem with your reasoning is that we may not have the resources to do it in a generation or so. If we don't do it now, there is every chance that we never will.
Your arguement is almost like saying that a one year old shouldn't try to walk because they'll be inefficient at it, it will be expensive (energy and time wise), and that they should wait until the technology (their musulature and nervous system) is more developed.
Slight oversimplification, but the idea is there.

OK, maybe my thoughts on this matter are a bit simplistic, but if you consider the Malthusian Catastrophe (sometimes known as the Malthusian Dilemma), it boils down to two things:
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:
I've ranted a bit more about this in one of my journals.
You are absolutely right, if there is a species threatening event in the next century, we are not prepared to deal with it. That is precicely why we have to go into space now. In that way we can deal with species threatening events when they arrive.
The problem with the species threatening events is that we do not know when they may happen, but we know that some of them will happen. Major impacts being a minor such threat. Some of them we will have warnings about a long time in advance, such as the inevitable fact that the Sun is going to run out of energy and inflate past the orbit of the earth. Others we will not have much of a warning about at all, such as a significant gamma ray burst in our neighborhood (within a few hundred lights).
With events where we have a warning, there will be (when they approach) a strong demand for evacuation, so we need to be prepared for that. Developing such technology will take millennia (or centuries at least). With the events where we will have no real warning, life on earth will be wiped out. Our safety net in that case is the fact that we have already colonized areas where the burst does not wipe out life.
Both scenarios requires we go into space big time as soon as possible.
