Colonization of the solar system


colonization is the act of relocating something into one's colon.

i have already colonized the sun, because it shines out from my backside.

After economic problems are out of the way, which I do not want this thread to be about and nor do I want it to be about "the human race needs to evolve into Vulcans before doing anything cool", what would be the best way to colonize the solar system?

Currently things are being set up for NASA just to issue guidelines and set milestones to achieve rather than controlling the space industry, here in America at least, and the ESA is doing psychological tests on a hypothetical trip to Mars, and JAXA is now testing the principle of the solar sail, so at least a few things are still going on which may help in the future. But once things are in order, what would be the best way to colonize the solar system? Should it be mainly by private corporations, by government agencies?

Should the moon be colonized first since it is closet and has minimal gravity, or should Mars be since its day is only 40 minutes longer than an Earth-day and its gravity is only half that of the Earth's moon and it's still close enough to the sun for photoelectric cells to function?

Should their be mining of the asteroid belt set up first or mining of the moon?

Should we continue to just build small ships on Earth to be shipped up as a whole, or should ships be assembled in orbit but having the parts brought up in multiple trips so as to allow heavier ships with larger cargo capacity and much larger fuel capacity?

Should interplanetary stations be built as halfway points between Earth and Mars so that transport vessels need not contain as much fuel?

Should space be allowed to be militarized in the event of curmudgeons in space?


I would say that the moon should be the first step. Mainly because it's the closest to Earth and because it can allow us to gain experience with operations off world for further expansion into space. Mars already has most of the resources needed to be able to build habitats there further down the line, though water is still an unknown. A habitat on Mars would to be placed where there is water, either at the poles or near the subterranean sources of water.

Does it? Perhaps you should show us your moon so that we can all see it. That would be entertaining.

Inflabe space stations also could be used. They are being developed by Bigelow Aerospace

There is no anti-gravity. Gravitation is the curvature of the space-time manifold. It is not a force radiating from some source.

From the context, I think he ment artificial gravity.

Artificial gravity is pretty easy to create. Just get your spacecraft to rotate and the acting centrifugal force feels exactly the same as a gravitational field.

CS Lewis, right? Well, I have a vague idea of the books, and it seems to be somehow similar to the Chronicles of Narnia, in the sense of greek/roman/etc mythology references? and it seems to be interesting actually, unlike Narnia.

Anyway, if we find aliens that are found to have a theology just like Christianity and very similar, then that would be very interesting. The issue is that the idea on how they must be on that aspect is influenced on our own preconceived perspective, I mean, from my standpoint, basing it on earth's history and anthropology, I would have some doubts on it, I mean, what if the religion that stands out from an alient planet is more similar to an ancient oriental religion than Christianity on earth, for example?

From your standpoint, that would be a confirmation of truth, and well, as a former Christian I was taught from the opinion of some at church that if there are other worlds, they would not have 'fallen' because the devil is here, not sure if you share some of that view. There are other christians however, that reject the idea of aliens.

Really? I do not see the word "artificial" anywhere in the original posting. I saw the word "anti" hence my response.

I know what you saw, hence my response.

Anyhow the term anti-gravity doesn't make much sense in that context, but I can't say for certain. Can't feel like mocking aspie literalism though, but sometimes it's quite fun.

Aspie literalism is the story of my life. I have only recently (in the past 20 years) been able to hide my literalism for social reasons. It makes life the the Normals a bit smoother for me.

Yep that would be CS Lewis. The first book of the series is the best in my opinion, probably just due to the setting being on the planet Mars and the three races of aliens in the book all basically being non-humanoid (well, the Seroni are humanoid-ish...). I liked Narnia as a kid though, at least the Voyage of the Dawn Treader in film version by the BBC and The Magician's Nephew in book format were interesting to me.

If it were more similar to an oriental religion? Then it would probably seem like that from Enemy Mine. In terms of implications regarding the nature of reality? About the same as going to a foreign culture here on Earth does. A lot of the oriental religions seem to focus more on social behavior and etiquette, and Indians are usually able to incorporate the theology of most other religious groups without much difficulty (I think this was talked about in a book called "Jesus, but among other gods" by Ravi Zachary or something like this, well not about aliens but about polytheism and just adding God to a collection of other deities.)

It wouldn't be a confirmation of truth if they believed in an oriental religion so it wouldn't be a confirmation of truth if they believed in God either, as that would be sort of an ad populum argument anyway and also subject to the events of their histories and as to whether they rejected God initially or not. I would consider that if God created sentient life elsewhere than Earth, that they also would have the ability to fall from grace (which is the premise of Perelandra by CS Lewis actually). However, it would depend upon the rules provided as to if they needed a sacrifice for individual sins or not. I don't see Christ dying twice, neither for angels nor for animals nor for aliens if they exist. However, as such, if God created sentient extraterrestrials who fell from grace, then they would be "fallen". And if any didn't fall from grace, they would be "innocent". And in this manner there would be a two-pronged classification based around the criterion of the existence of original sin.

Yes, well hopefully the economic outlook changes eventually.

Space colonization like colonization of the "Americas" is likely to be driven by a desire for groups to escape from their own societies and establish new ones. I can imagine groups of all different stripes, especially those with clear political agendas coming together, setting up a colonization company, and landing on other planets.

Space colonization is going to open the floodgates of social experimentation. Whether independent or not the amount of social control that can exercised from Earth will be tiny if not nonexistant. They can pass all the laws they want, but colonies set up in space are likely to be extremely closeknit(since they're basically stuck at the colony, can't even go outside without a spacesuit) to the point where they will be able to simply report they followed all the rules while doing things completely different and nobody will blow a whistle. By the time this is discovered it will be too late. Depending on the political atmosphere on Earth they might just let it go, or there might be a space war of independence for a number of these colonies similar to the American Revolution. Corporate control will be about as difficult if not more than political control, and corporate sponsorship is likely to be a factor in starting a number of colonies. Investment will probably be great at first until the corporations find a number of colonies just stop paying and it's too expensive to be worth doing anything about it because of the vast distances.

Compared to sailing wooden ships across the Atlantic, the up front costs of manned space flight to the only other planets we can possible colonize (Moon and Mars) is out of reach.

The last time I thought about this issue was around 1980 when the world was abuzz with a whole new concept of space colonization: neither Mars nor the Moon would be our actual home- was the new think- it would be city sized colonies floating at "lagrange points" in space itsself.

Large cylinders would slowly rotate creating their own artificial gravity out of centripredal force. Pairs of cylinders rotating in opposit directions (to remain stable) would be built in progressively bigger sizes until you had fifteen mile long colonies with millions of people in an artificial earth-like environment.

They would exploit the unlimited potential for solar energy in deep space by being powered by solar cells. And the raw material to build them would come from mining asteroids or the moon.

These artificial moons would be placed at Lagrange points- places in the earth-moon system where earth and moon's gravity kinda even out and keeps the position stable.

The book "the High Frontier" goes into the details. Forget the author's name.

Sounded feasible to me at the time. Perhaps some combination of that concept and actual colonies on the moon or mars would occur.

Moon would be a great guilt-free place to strip mine though. No need to save the ecology of a place that has no ecology! We could use hydrogen bombs to help blast out ores.
