Talk:Colonization of the outer Solar System

message: 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...

replies: text: There's still a bit about that in the article, but it should probably be removed, since no one actually seriously considers it. All RS's that I can see think about the moons of Jupiter and Saturn – even the moons of Uranus and Neptune seem too futuristic for them, so the giants themselves should be even more so.

thread_title: separate articles

message: 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.

thread_title:  Future expansion 

message: 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?

thread_title:  Uranus 

message: While it's probably true that there are goodies out there from which to manufacture rocket fuel, let us remember that even interplanetary distances are so damn far as to make rocket propulsion for getting around amongst them downright silly. for instance, if we are to accelerate to even 100 miles per second, it would still take ~ 7 years just to get to Jupiter, let alone to Saturn, which is roughly twice as far out. I'm not going to do the joules-to-matter math here, but at joule you can see how much energy is required for this sort of trip. Even if you were to use fusion instead of, say, potassium perchlorate, and get much higher efficiency, it would still take an awful long time to get anything done. So, consider the phrase 'sustain life,' which is far more generic. I don't think anyone is going to deny that there are organic compounds (Io and Titan come to mind), water ice (Europa), and liquid water (Europa again) out there. Further, the previously mentioned ingredients plus sunlight do life sustainment make. Indeed, even without sunlight, Jupiter and Io are pretty warm places to hang out. This has been speculated ad nauseum in (science) fiction, and recently by the likes of NASA with, say, the Huygens probe. Anyhow, I think it doesn't need the  template now. At least not there. 63.242.163.2 23:47, 24 September 2007 (UTC)

text: Your edit seems to be based on OR, and from looking at it, you've made some mistakes with your analysis; for example, Cassini used a Venus slingshot I believe.WolfKeeper 04:57, 25 September 2007 (UTC)
replies: text: Not having tracked more than the last bit of this exchange, just to pipe in with my two cents - there are references out there, which we should collect, for outer Solar System resources being susceptible to exploitation as rocket fuel; Cassini used slingshots of Venus, Venus a second time, Earth, Earth a second time, [fact-checked self — r.d.] and then Jupiter, after originally being launched with chemical rocket fuel; and the relative crappiness of chemical propellant doesn't nullify the potential value of developing chemical propellant resources in the outer Solar System - it can be combined with other techniques, as the creative slingshotting of the Cassini mission planners illustrated, and don't forget that it can be used to ship slow-boat freight, for shipments with relatively low time decay in value per mass density. Spacecraft don't need to move that fast when there are no or few people in them, to be of value. - Reaverdrop (talk/nl) 05:11, 25 September 2007 (UTC)
