Also, Jupiter, it's impossible for us to colonize ourselves into other planets. It's just not possible.
Wo! I did not see this...thanks for pointing it out Plissken.
Well, Christian, consider this:
QUOTE
The ISS is operated by Expedition crews, and has been continuously staffed since 2 November 2000, meaning the ISS programme has maintained an uninterrupted human presence in space for the past 9 years and 186 days, which is approaching the current record, set aboard Mir, of 9 years and 257 days.[15] As of 18 March 2010, the crew of Expedition 23 is aboard.
Also consider that there have been permanent human residences underground and in the arctic regions, for decades. And that people have lived underwater for extended periods of time (not least of all in a submarine...) for ages. We are capable of acclimating ourselves to formerly inhospitable places.
Further, consider this:
Timetable for Moon colony announced...while Obama--unfortunately--scrapped that plan it certainly was
possible. Right? I mean... a lot of the smartest scientists in the world thought it was.
And that's all with today's technology, or near-future technology. I mean, in decades hence, lots will be possible. Not just through advanced rocket science and robotics, but also through rapidly developing fields like materials engineering (nano-engineering) and genetics. And in centuries hence...yeesh...think of what the world was like in, say, 1500, or 1800 even!...and in millennia hence...
I have no doubt that colonizing other worlds will be possible, even if it is a massive, extremely long term, and mountainously expensive endeavor. Not only that, I think it is highly probable to the point of near-certainty. Not only that...I think if there were a massive worldwide effort, it would be possible inside of 10 years or so to set up a colony on Mars, let alone the moon, which would be easy.
It's just a matter of perceived cost-benefit and political will, technology will not be the primary obstacle.
EDIT: We are already practicing for this eventuality.
