Sheeit, I think we have enough nuclear power, insulation and refrigeration technology that we could colonize Venus if we really tried.

moon is nice though because it is not some long-ass trip where you get a shit-ton of radiation (until we can figure out how to *practically* launch enough shielding).

It is about 50 degrees 50km above the ground, where Terra air-filled balloons would float and be able to hold a relatively large station. Under some conditions, you could walk outside with just oxygen needed, because the air pressure is similar to that of Earth's at this altitude.

Just 5km above 50km, temperatures rest around 27 degrees. You'd only need basic cooling indoors, and outdoors it would be manageable because the heat comes from the surface, not the sunlight (correct?).

I agree, but then again, some people live in the torrid desert, others in the arctic where not even a single tree sprouts. They live there because they don't know better and they couldn't afford any differently anyways.
It's hard to believe, but if mankind actually does find ways to go live in inhospitable places, ownership of, and competition for resources will eventually push the destitute there.
Sad, many such places.

Deploy air-filled balloon a few km below 50km, it floats up to 50km. Use the spacecraft as a temporary base (still attached to the balloon, so no thrust is needed to stay in the air), while you develop the colony around it. Easy. The atmosphere protects against radiation. The temperature is manageable at that altitude to work outside with just minor heat protection and air tubes. The atmospheric pressure is nearly the same as on Terra, so no pressurised suits are needed. Gravity is virtually the same, so long term stay is viable.

Where to even begin. You have absolutely no idea what you are talking about. 0.4 is not microgravity. 0G or 0.0003G are.
All the bad effects you talk about apply to research done on the ISS. In 0G.
We have no data points about what (significant gravity < Earth gravity) does to the human body.

Second item on the schedule. Nonlinear dynamics. Do you understand what that means? Growing up in 0.4G doesn't necessarily mean your body (like bones, etc.) is only 40% as strong. It might just mean you are 90% as strong, because most of the beneficial effects happen if *any* significant gravity is applied to the body. The dynamic is -- in this model (which is much more likely to be correct than not) non-linear. This explanation is enough, right?

Engineer bacteria that eat the undesirable gases in the atmosphere and shit out oxygen and nitrogen. Limit their ability to evolve. Gases used as food source or in part of their metabolism runs out, bacteria die. Venus now has nominally breathable atmosphere.

If the atmospheric conditions change to become more like earth, temperatures will drop. Perhaps we can even seed rain clouds to rain water onto the planet. This is all far easier than Mars shit. It's closer to earth too.

there are ways to fuel rockets without hydrogen - it's much less efficient in terms of Isp because of how light hydrogen atoms are, but it's doable. that is actually one of the ideas for a Mars ISRU rocket, since hydrogen is at a premium there, too, barring near surface ices, hydrates, or ammonium minerals (we don't really know how much of these there are on any planet without going there and prospecting; while hydrates are unlikely on Venus, it's even possible Venus has some usable hydroxyl-bearing minerals, as the -OH group often displaces halogens in minerals and is remarkably stable even in extreme environments in Earth's interior despite the volatility of water, tending to become trapped within crystal lattices, especially silicates, when it isn't just flat out stable as a mineral)

the design is specifically an O2 + CO rocket, but Venus has an advantage there for rocketry that Mars doesn't (barring speculation about the amounts of available nitrogenous minerals on or near the Martian surface): AMPLE nitrogen, meaning more than enough to not worry about expending it. because of that, a hydrogen-free rocket for leaving Venus might be able to use N2O or N2O4 as its oxidizer, as well as fuels using -CN groups or even azides if we're feeling spicy, to get better performance than an O2 + CO rocket. in either case, the energy to manufacture these substances with ISRU is plentiful on Venus, meaning there's no real need to deliver nuclear reactors for power as there would be on Mars.

cloud seeding for water only works if there's sufficient water vapor in the atmosphere. that's not the case with Venus. you will almost certainly need water from elsewhere. however... that's doable.

if it's simply impossible to deliver water from further out in the solar system (it shouldn't be; there's ludicrous amounts of it past the ice line, so much so it's basically waste material out there), there's also the option of collecting the solar wind (lots of protons and electrons; basically free hydrogen, and a greater flux the closer you are to the sun) and reacting it with native Venusian oxygen from breaking up CO2. that process would likely actually give you net energy, but it would take much longer to give you enough hydrogen than deliveries from the outer solar system would, even with the long transit times on human timescales.

once sufficiently cooled, you also want to give Venus an artificial magnetic field. no MHD core-spinning nonsense required - with latitudinal superconducting rings, this is surprisingly easy to do. we're talking merely a few dozen gigawatts, something we already do on Earth fairly easily.

however, it's important to remember that you'll need much more water than just filling the low lying areas; the existing water equilibrium means much of your initial delivered water to a cooled Venus will be consumed by anhydrous minerals re-hydrating until you exceed that equilibrium, so the slower but more long-term sustainable process of solar wind harvesting might have the advantage there. once past the equilibrium of all the water going into minerals (i.e. achieving stable surface water), hydrated minerals do help you: they'll help to stabilize the water equilibrium by releasing their water as you lose it to the solar wind, so they provide a buffer even before you set up your magnetosphere to protect the water (you'll be losing Venus' existing generated magnetosphere as you make the atmosphere less hot and dense).

Venus has historically been ignored because it's extremely inhospitable to both man and machine and it's also difficult to observe at a distance due to its atmosphere. In terms of terraforming Venus has a lot of issues but all of them are fixable whereas Mars will never have enough mass for Earth like gravity (I guess you could crash Mercury into it or something but is it really the same planet at that point?). Regarding terraforming the atmosphere on Venus it could be reduced by blocking sunlight to the planet causing it to freeze and then physically mining it out or ablating it away with a solar lifter. I'm not sure if the latter method could also be used to induce spin on the planet and if not a series of orbital mirrors/shades could be used to replicate Earth's day/night cycle. If you're willing to spend the energy you could also just bombard the planet with impact to induce spin. It would require an absurd number of asteroid impacts though. Then there's the lack of a magnetosphere to consider. I don't know if making the planet spin would be enough to induce one. If not an artificial dipole can be constructed in synchronous orbit between it and the sun. The lack of hydrogen on the planet is the easiest thing to fix, just bombard it with water rich asteroids or maybe even a frozen moon (Jupiter has plenty to spare). Once that's done it's a matter of removing all the poisons leftover from the shitty atmosphere and converting its remaining carbon dioxide atmosphere into oxygen and nitrogen. You could probably engineer some bacteria to strip out the poison and carbon, and some nitrogen asteroids could sure up the nitrogen content of the atmosphere. At that point it's just a matter of building up a biosphere by introducing organisms. If you want to go the extra mile and have tides you could steal a moon from one of the gas giants or maybe use Ceres. Venus has a ton of issues but unlike the mass issue with Mars they are all fixable.

Venus actually has ~4 times the amount of nitrogen in its atmosphere that Earth does - the "3.5% nitrogen" thing is misleading at first glance. there's so much fucking Venusian atmosphere that 3.5% of it is still more gas than Earth's entire atmosphere, several times over.

literally the ONLY thing you need to add is hydrogen. Venus is legitimately a "just cool and add water" planet.

however, you're going to have an enormous excess of oxygen from splitting the CO2, so rather than adding water it may be better to approach this with solar wind harvesting or even gas giant "mining" so you can just collect hydrogen and sequester some of the oxygen in water produced in situ (and thus mineral hydrates as well). you can directly reduce CO2 with hydrogen, to various things including methane (probably not a good idea; very potent greenhouse effect) or just solid carbon. could also possibly export the oxygen to other places. or some of the carbon (there's more of it in the Venusian atmosphere than all known carbon reservoirs on Earth combined)

that said, it's possible Venus' crust is somewhat reducing (i.e. will scavenge free oxygen) because of how much oxygen is locked up in atmospheric CO2, some of which may have resulted from certain oxide minerals in the crust being carbothermally reduced. we know very little about Venus' crust composition, but for an example of this, the presence of magnetite or wustite (Fe3O4 or FeO respectively) would each scavenge free oxygen out of equilibrium to form hematite, or Fe2O3. we actually already know that carbon reacts with magnetite to form wustite and CO, and CO is itself a reducing gas (it's how iron is smelted by solid carbon in the form of coal/charcoal/coke - CO forms and reduces the iron oxides to iron, forming CO2). iron oxides are far from the only potential surface mineral that would do this.

This is why we're calling you out for watching too much capeshit. It's probably not impossible, but this alone is an incredibly large engineering project today. We have yet to do this on Earth to say transfer solar power from one side of the Earth to the other so it works at night. And it's the wrong problem to focus on too when discussing terraforming Venus. An earth like atmosphere itself would already provide ample shielding and atmosphere loss rate is so not a problem. Focusing on this problem while completely ignoring cooling Venus is pretty funny

what part of "ISRU" do you not understand? or just... rockets in general? even if you were using the same rocket, you wouldn't be 'lifting' any fuel between the two bodies. you wouldn't be using the same lower stages on both planets even if you reuse them. lower stages don't fucking come with you, and that's most of your fuel.
>At colony altitude ... solar power
you could just float your panels higher than the colony if you really needed to (balloons are quite a lot of solar panel real estate even for Earth-level solar flux). or just use the differential windspeeds. or the temperature gradient for heat engines. usable energy is usable energy.

>disperse
the word you wanted is "diffuse." the clouds are thin, yes, but there really IS enough to pull hydrogen out of it at useful rates for a balloon habitat.
>hydrocarbon plastics
you'd want halogenated plastics, likely fluoropolymers, for your exterior balloon materials (sulfuric acid will slowly degrade polyolefins), and solid carbon for bulk structure absolutely everywhere you can possibly help it. you don't need much material for balloons, though, so there will almost certainly be more hydrogen in your water and total biomass than anything else regardless.

Aside from using it as a scientific research outpost, what possible reason would anyone have to set up a "colony" that's entirely reliant on maintaining buoyancy to avoid plunging into the depths of hell? Almost everything would have to be shipped in from space, you'd have to maintain an airtight environment at all times, your day/night cycle would be entirely artificial, and again - your only escape options are orbit or death.

If you could get some kind of space elevator deal happening with your atmospheric colony tethered to a geosynchronous station, it might make a bit more sense, but even then it seems like a pointless endeavor outside of academic research.

It does have similar gravity, which the most improbable issue to "fix" with any planet. But you would still need an absurd amount of energy and time to "terraform" Venus. The atmosphere not only needs major reductions in certain gases, it needs an immense amount of water. And after that, you'll need to kick-start plate tectonics and account for the proximity to the Sun, otherwise another runaway greenhouse cycle will occur.

jesus fuck no you don't. if you can draw down the atmospheric CO2 enough to allow livable temps, you can do it at much smaller scales to prevent another runaway. kickstarting tectonics is one of the more harebrained ideas to remove CO2 over geologocally long timescales, not something you have to do post-terraforming. there legitimately might not be enough lifespan left in the sun to make that work.

it's on the level of "just grab a fucking ice moon and crash it into the fucking planet" nonsense (because that's really the only way you're getting enough energy into the Venusian mantle for "kickstarting" tectonics anyway) - the amount of energy required to pilot a fucking moon is absolutely retarded compared to just in situ disassembling the hapless satellite and sending it piecemeal through the Interplanetary Transport Network on circuitous and decades-long routes to Venus. because you have to do it the long way regardless, because you're only going to be able to move the moon in question through the Interplanetary Transport Network unless you have fucking country-sized rockets with effectively infinite reaction mass and energy (now you only need CITY sized rockets). oh, and all that delta V to get to Venus turns to heat immediately on impact. you were trying to get rid of that. whoops.

the problem with the moon thing is scale - you could disassemble an ice moon or pull hydrogen from a gas giant and send it to Venus in sufficient volumes, and with sufficient cooling efforts, to terraform it. that's all surprisingly feasible from an energy standpoint, and from a timescale standpoint we're talking a few tens of thousands of years (i.e. roughly on the order of the timeline of human history; staggeringly fast for geologic timescales).

the moon thing is orders of magnitude more intensive. people do not understand how much energy is required to change the orbit of a massive body, even one as "small" as a moon. it's not like moving an asteroid - those moons are where they are because they're in relatively stable, local minimum conditions for their orbital energy. to move them OUT of those positions, one has to re-input ALL the energy that they've lost to stabilizing their orbits on timescales of tens of years instead of the hundreds of millions of years over which their orbits stabilized. the power required increases by several orders of magnitude over everything that humans currently produce, which is in turn a couple of orders of magnitude over everything that humans will feasibly produce with more power generation in that timeframe, and much, much greater than that required to just mine for hydrogen and ice and deliver it slowly. you can't put objects above a certain mass through the Interplanetary Transport Network, so you can save immense amounts of energy by using it with thousands of smaller scale deliveries.

the piecemeal approach isn't instant gratification like the moon approach is. that's really the only reason people suggest the moon approach - they want it done quickly rather than efficiently. that lack of efficiency happens to also take it well out of the realm of feasibility.

everything that anon said EXCEPT the solar wind thing is somewhat reasonable; in and near the ecliptic, it's just not enough mass unless you've got a million years and a few million planet-sized (in collection cross-section, not mass, at least) collectors to spare. this is based on a super rough calculation/estimate i just did that suggested a single solar wind collector (at least in the ecliptic, i think it's denser at the poles but don't quote me) at Venus' orbital distance and with a cross-sectional area equal to Venus would fill a Venusian ocean... in a couple trillion years. you'd need about a million of those to cut it down to "only" a couple million years. yes, solar wind density increases roughly with the square of a reduction in orbital distance, but you still need fucking loads of collection area, and the closer you are the harder it gets to keep from vaporizing... also by the square of the reduction in orbital distance.

just pull it out of the gas giants. much easier. the gas giants will literally not even notice, they've got more than enough to spare.

to get hydrogen in reasonable timescales from Sol, you'd basically need starlifting. personally, i think we'll be doing that eventually (if nothing else, just to sidestep the red giant phase - starlifting increases star lifespan), but that'd be so far in the future we'd have almost certainly already terraformed both Venus AND Mars, and have loads of space habitats all over the place, and have probably sent off ships for colonizing other star systems.

Mercury's fucked though. we're 100% going to rip that poor planet to shreds. maybe even make artificial moons for Venus and Mars with the leftovers while we're at it, just because we can.

Ejecting Enceladus from Saturn on a collision course from Venus only requires 630 m/s of delta V. This is relatively small due to the possibility of performing gravity assists with Saturn's other moons. This could be done by launching pellets to power a huge steam rocket on Enceladus from a light sail driven 'wind mill' near the sun. This could provide the required energy to eject Enceladus in one year. This is an utterly huge and ridiculous engineering effort, but not impossible.

you don't need nearly as much as you think. it's only for exterior lining. bulk structure will be pure carbon wherever you can help it - that includes light, semi-elastic fillers such as aerographene.

people quote the "pebble vs. Mars" thing because it's catchy and hilarious, but it's not realistic, and may literally be untrue due to other constraints (timescales, adequate mass ladders, complex orbital interactions between similar-mass bodies). Birch also mentions gas giant hydrogen, but his energy budget for it is inexplicably still orbital momentum exchange, limiting the mass throughput by orders of magnitude. he also vastly overestimates the ice proportion of the moons.

counterintuitive as it seems, the most valuable thing on Venus is literally its atmosphere. there's more carbon floating over Venus than all known reservoirs on Earth, including carbonate rocks.

Venus is in the rather unique position where building a bunch of space habitats would actually assist in terraforming the planet - carbon's surprisingly hard to come by in the inner solar system apart from Venus (people tend to vastly overestimate the mass of Martian carbon; all the Martian CO2 in its atmosphere is only about 3 times the amount in Earth's atmosphere, Mars' atmosphere is pitiful), and space habitats like O'Neill cylinders will need a lot of it for their biospheres.

on human timescales, sure. with local resources alone, definitely.
>Rodriguez well
most (yes, even including the likely majority ice ones) Martian 'glaciers' are more like rock glaciers on Earth (loose debris with ice inclusions deposited by glacier loss). Martian atmospheric pressure would cause much faster refreezing from faster mass loss - to the point it's potentially energetically favorable to just mine. Any liquid well will also likely concentrate any salts the fluid contacts, requiring higher energy for distillation.
realistically you go to an exposed ice scarp and cut holes in the cap, collecting what sublimates. but there are only 6 such locations known.
>propellant
likely not what it'd be used for on Venus; hydrogenated propellants are best, yes, but not the only ones. N2O being both a usable monopropellant (not talking about the dumb fuel blend) and oxidizer helps significantly.
>ridiculous to move significant amounts of power via wire ~10 km
hmm
>variable wind speed
Venusian wind is incredibly stable - almost completely zonal flow. we also already have balloons with 7.5km+ ground tethers. look up TARS aerostats. Venusian wind stability pretty much eliminates what makes kite wind power suck so much on Earth.
>pipe
likely a hanging, open-bottomed updraft-tower-like structure with low-density walls; could even be buoyant, since all you need is a barrier to constrain flow. wouldn't need to be super long (better temperature gradient than Earth).
>drag
a colony is likely moving with the wind; would circle the equator in about 7 days.
this can also provide power, with the colony acting as the "sail" for dragging wind harvesting structures through the slower-moving atmosphere below the cloud deck.
>efficiency
100% efficiency isn't necessary when the collection area can be that small. the balloons will already be substantially bigger. my math wouldn't be any different unless you were just wrong. nobody owns these numbers.
