alright I get just hit n' run posting weird soviet art doesn't get my point across very well so let me break this down for y'all you know what's already at sea level pressure? the upper atmosphere of venus. you know what's already got real good shielding from solar radiation? fuckin' venus. you know what won't turn your bones into pool noodles like space or mars would? the 90% earths gravity on mother fuckin' venus. https://www.youtube.com/watch?v=0az7DEwG68A

why can't we build sky cities on earth, what benefits does venus bring?

you're also facing a number of other challenges: your cities have to be bouyant, which is going to place massive limits on what they can look like/how much they cost you have to do that while still dealing with weather you have to harvest metal/metal ores to actually make anything, which means dealing with the surface and its conditions you still have to escape the venutian gravity well to get back into space, which means launching back from ~1g (also you're launching from floating cities, totes safe right?) you're going to need exotic materials to make the whole thing work, because you're essentially building a 'shorter' space elevator compared to those problems, shielding from space rays & inertial gravity isn't that hard

Normal rear end earth air floats in the venusian atmosphere, so we just need a steel balloon full of that and we're good. We could probably figure a way out to make cloud cities here too but we don't really need them. Compared to mars venus is way easier to live on, but nothings ever gonna beat living on earth. Although I guess the biggest problem with venus as a colony is we don't really 'get' anything from it other than living space. Except for what we skim from the clouds, all the resources are on the surface and we haven't made anything that survives THAT for more than a couple of minutes. edit: also all those things rudatron said. Some of those are probably easier to overcome than they sound but eventually you either have to deal with getting to the surface or getting to space.

However gravity is still the hugest issue with space colonies and isn't as easy to handwave as it sounds. To make a station have proper gravity it either has to spin really fast or be incredibly big, both of which introduce more problems. We can deal with most of the other issues with space okay but humans do very badly over a long time without gravity. I'd definitely take a space station over mars though.

mars is extremely cold and dry and that sounds good to me as somewhere to live. gently caress venus and its boiling acid atmosphere

Just get a hose from the venusian atmosphere into space and pump it into ships to unload into mars and replenish its own sparse atmosphere. Optimally, that makes two more habitable planets as mars has a dense enough atmosphere to keep liquid water on the surface and shields against radiation and Venus gets a thinner atmosphere that doesn't crush everything at the surface (it's still acidic as gently caress, but it's one less problem on the whole).

there is no way that happens even in super future what might happen is redirecting comets to smash into mars along with big googly oogly vats of engineered bacteria

One issue of built orbital stations I don't see come up often is that of just keeping up with the gradual decay of the interior and the structure itself. Condensed water, particulates, microorganisms, etc. is going to build up everywhere and corrode stuff, especially in inaccessible places like ducts and the insides of machinery, so it needs to be easy to keep clean. Even so, modules would have to be continuously broken up and replaced when their maintenance stopped being cost-effective. And with a small, closed ecosystem and low organic diversity you're going to be facing the space version of algal blooms. Simulated gravity, direct sunlight, clean air, downtime, etc: All luxuries. A space habitat is going to look (and presumably smell) something like this most of the time: In general, I suspect there are big remaining challenges in a lot of relatively unglamorous fields like ecology, biology, industrial processes and modular design. The rocket stuff is mostly working, and it's just a tiny piece of the puzzle anyhow.

You seem to be awfully glib about the fact the atmosphere is saturated with sulphuric acid, which seems like something to account for when talking about the ease of maintaining a colony.

We're talking about space colonization. When the other problems you deal with include solar radiation, cosmic radiation, gravity sickness, hard vacuum, extreme temperature differences, and micrometeorites, sulfuric acid honestly seems quaint. Personally I'm of the opinion that simulated gravity via rotation is not a luxury, but necessary to a permanent habitat in space. And when I say permanent, I mean people living entire lifetimes in it, not just a year or two. Concordat has issued a correction as of 20:39 on Dec 13, 2016 |

The most reasonable proposals for terraforming Venus involve solar shades, and even those are gigastructures when compared to the current scale of human production.

And when I say permanent, I mean people living entire lifetimes in it, not just a year or two. Yeah, people won't survive for long in space without being centrifuged. What I meant though, is that you won't necessarily be able to assume that spilled/condensed fluids and detritus will find its way to a drain/floor/air filter everywhere. There'd likely be central storage/work areas where stuff weighed very little and instruments for comms and observation could be at ~rest relative to the central axis. People would spend a lot of time there. Also, space near the rotating edges may be at a premium, and animals (if any) and plants tend to need gravity too. I'm thinking maybe two orders of magnitude bigger than the ISS, though, not a far future megastructure where anything might be possible.

I was looking up articles on tinnitus when I found this gem buried in the comments section quote:So, is the sound we're hearing originating from the 'Cube?" Not the Mecca Cube, but the real one on the North Pole of Saturn? What I hear is a match for the sounds I hear from Youtube's Saturn (north pole) videos. NASA now says life probably started from 'seed bursts' from the Saturn Moon Enceladus, which is obviously derived from the Sumerian, Enki, who was thought to be the R1A & R1B Y-Haplo creator. Demiurge on behalf of Saturn. Man, still having a hard time w/ the moon landing and now we're suppose to know how our soul (Sew EL = Righteousness) is manufactured? Supposedly spends time with the Father, then Mother, then here = children are little gods to be corrupted. So yeah, Enceladus it is, baby! Hopefully whatever microscopic forms of life swimming around beneath the ice (fingers crossed!) won't mind us moving in.

It's really, really thick, so you'd have essentially infinite space. Then melt it for water and separate it into O2 and H2 for breathable air and party balloons.
