The Top Three Reasons for Humans in Space 732
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.

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.

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?

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.
