[edit] About the introducton

I am not sure their is any formal proof of existing liquid water anywhere in the solar sytem. Steam and ice, and traces of rivers that might have been of liquid water, yes -- but no actual present water.

• so interresting and good source of info. This is wikipedia at its best. Congrat's ;)

I just disagree with the word "iceteroids" because asteroids is from aster+ oids (like a star). At max, it would be iceoids, maybe... -Pedro 00:55, 15 November 2005 (UTC)

Well, you and Mr. Zubrin can have it out. For now, it's a common portmanteau. siafu 01:40, 15 November 2005 (UTC)

[edit] Ganymede, Triton

Are there any ideas for these and other major moons? -Pedro 16:06, 18 November 2005 (UTC)

• • An old book that I read had an issue about Ganymede (The Base Ganymede), but without details. :/.--Pedro 19:47, 18 November 2005 (UTC)
  • I've added what I read about Ganymede. It is maybe outdated (the magnetic field was not in that source, obviously). I dont own the book, i just copied the pages about future space exploration.--Pedro 19:58, 18 November 2005 (UTC)

• I know this isnt the place, but there are also ideas for the colonization and terraforming of Venus. -Pedro 20:08, 18 November 2005 (UTC)

• • There's some information about terraforming Venus over at terraforming (it's down after the stuff about Mars). It might be worthwhile to branch it out into something like Colonization of Venus, but we should talk about that over there. siafu 22:39, 18 November 2005 (UTC)

[edit] separate articles

do you think there should be separate articles for Titan and Europa? --Revolución hablar ver 17:47, 20 March 2006 (UTC)

No, as Titan and Europa are two very different environments, one having a thick atmosphere (Titan), and the other a deep ocean (Europa). Felix Dance 11:37, 1 December 2006 (UTC)

[edit] Future expansion

I saw that someone added in a bunch of links to articles with no content, and that someone else deleted them. Let's build these articles on this page first, like for Pluto and each individual satellite. Once we get more than a page for each, we can see about breaking it off. Until then, it's not worth it. Chadlupkes 04:44, 15 May 2006 (UTC)

I did the deleting (actually reverting to redirects here) and I agree with you. I left comments on the incident at Wikipedia talk:WikiProject Space Colonization--agr 10:40, 15 May 2006 (UTC)

[edit] Uranus

The section states: "By using balloons filled with hydrogen, large masses can be suspended underneath at roughly Earth gravity. "

But Uranus atmosphere is itself mostly hydrogen. So I doubt the faculty of this statement. Does anyone have more information on this?

84.160.237.96 21:52, 29 November 2006 (UTC)

Yes, Uranus' atmosphere, as well as the other gas giants, is not entirely composed of hydrogen. According to NASA's fact sheets (http://nssdc.gsfc.nasa.gov/planetary/factsheet/uranusfact.html), Uranus' atmosphere is comprised of only 82.5% hydrogen, with the remainder being mainly helium and methane (which is 2.3%). This would easily be enough to provide boyancy for a large aerostat, with some proposals suggesting hanging loads of several thousand tons suspended below hydrogen spheres over a kilometre in diameter, although I do not have a reference for this at the moment. Felix Dance 11:35, 1 December 2006 (UTC)

I recon that those constructs of sphreres for the hydrogen need not be able to endure high pressure densities as the hydrogen inside would have the same preasure as the atmosphere outside, but would have to be very large to provide sufficiant boyancy. Large constructs tend to be heavy. So how exactly would these sphreres look like? If the hydrogen would be under preassure to retain structural stability of the sphere, it'll surely leak out through almost all materials. If not, the sphere needs to have structural stability of its own, adding weight to the structure, decreasing the overall density.

Are there any numberes on that subject? 84.160.217.236 19:45, 2 December 2006 (UTC)
