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.

      This article is rediculous. First of all, humans in space is a complete joke: there is very little of interest in space. Humans on other planets is another story.

      I disagree with your statement that there is very little of interest in space. Both asteroids and comets are of great interest. Why, you ask? Many comets are made of ice -- frozen water, which will be quite useful if we're going to create colonies either in space or on the surface of other worlds. In addition, if we keep on pumping crap into Earth's rivers, lakes, and oceans we may need some of that water ourselves in the not-too-distant future.

      As for asteroids, the C-type, S-type, and M-type asteroids could provide us with valuable resources for manufacturing, either for products to be used to explore other planets or for products to ship back to Earth.

      Colonizing the ocean floor would be much more difficult than colonizing space. In space, the pressure difference between inside the space capsule (1 atmosphere) and outside (0 atmosphere) is 1 atmosphere, so the space capsule doesn't have to withstand _that_ much pressure. I believe that in the ocean, the outside pressure increases by 1 atmosphere every 10 meters or so -- meaning that if you want to go down 1000 meters, your ocean capsule has to withstand a pressure differential of 99 atmospheres pressing in. Now true, you'd have to travel farther to get to orbit than you would to get to the ocean floor, but the conditions at your destination are actually better in space in terms of pressure.

      Your final comment was 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.. Think of it as an insurance policy. Right now, if something were to happen, humanity is an uninsured "liver" (one who lives) and we'd be screwed. If we had the insurance policy of a self-sustaining colony off-planet, then even if something were to happen to Earth that kills off humanity, we can fall back on our insurance policy.

      It's not a matter of whether or not anyplace else is safer than Earth -- I wouldn't exactly say Earth is all that safe right now. Read the current concerns about nuclear warfare. Add to that biological and chemical weapons and I think you'll see we could do a pretty damn good job killing off either all life or just all human life on the planet. If that were to happen, I wouldn't want that to be the end of humanity.

      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?
