Of course. Colonizing and terraforming Venus must be humanity's ambition since Mars is just a false hope. Mars can never become like Earth. Venus can become much like Earth if we put a lot of effort into it. Cost what it will. We may have no better option for a great deal of time. Some civilizations emerging might not have as good options as we do --- both Venus and Mars are very great neighbours. We could mine Mars and terraform Venus.

However, after we've gotten good at making space stations, filling the inner solar system with islands of them and selling exotic locations as tourist destinations, we may eventually create technology (I'm guessing nanotech and mega-structure skills) to do these things like sun-shades and co2 scoopers. Trying to build such mega-structures the way we build things nowadays would be way too inefficient and slow and risky. I'm guessing the future outfit who would build the Venus sun-shade would be a power utility company. Why build a shade when you can build a solar collector? Also, the thing would inadvertently be a giant solar sail by implication, so it would need to somehow maintain its own position. Extreme amount of energy required just for that.

Odds are that we will slowly transition to different energy systems that have no emissions as we improve existing tech, create new tech, and simply out of necessity caused by the market. It only becomes a problem when we try to force too much of it too fast, or in the wrong way. Raising energy prices too far will literally kill people, especially in the poorer countries. Eventually plants will consume excess CO2 from the few centuries worth of combustion power. For example, wind and especially solar power is slowly becoming viable, however they only work well in a decentralized fashion. Another-words, solar on every house is somewhat viable, while solar farms are not. Also cool: if you have enough solar houses, eventually the grid has the potential to stay online without any output from power plants because the houses "exchange" excess power.

To accelerate the Mercury (with mass about 328.5*(10^21) kg) to the speed of just 1 mph, you would need (according to classical mechanics) energy that 1,000 ordinary power plants (10^9 J/s) would produce in about 2,340 years. To stop Mercury from its rotation around the Sun (average orbital speed of Mercury is about 106,000 mph) you would better need to create a Dyson sphere around the Sun because you would need the whole energy that the Sun would produce (1.4*(10^31) J/h) in 1 day and 2 hours! With the technology and ability to move planets, and not only to move them but to move them over that long distances (closest distance between Mercury and Venus is about 26 million miles, longest distance is about 108 million miles), you could just give the Venus the spin instantly without the need to move any planet and it would be much much more easier and much much more efficient. You could also just move Venus further from the Sun.

I've been trying to figure out what would happen if we instafroze the entirety of Venus for a while now and this partly answered this.

Right, if you could block the sunlight, then the planet would cool down to the point that the atmosphere would just fall as snow.

Yes, yes we can! Step 1: Send engineered microbes that float above the above the dangerous clouds. They convert carbon dioxide into oxygen and we also send in microbes to produce nitrogen. Step 2: Start pumping in anti-greenhouse gasses. Release above the clouds reflective molecules. Pump ozone. Step 4: After the greenhouse gas is eaten away, we start bombarding Venus with asteriods with a lot of water in them. This will also speed up the rotation of Venus. The Water will help to reflect light from the sun. We would want more water on Venus than on Earth so to block out sun light. Step 5: Get algae microbes in the water. They'll produce oxygen form the remaining carbon dioxide. Step 6: Insert plants, and engineered worms, and bacteria. The plants eat up carbon dioxide, the worms till the soil, and the bacteria make nitrogen. Step 7: Insert animals and ecosystems. (We have to be careful here.) Step 8: Jumpstart the magnetosphere, (so it doesn't revert again) with the sped up rotation and nuclear elements will give Venus a magnetosphere. Step 9: Get a dwarf planet and have it orbit Venus. This will stabilize Venus's rotation, and mix the mantel. Step 10: Humanity colonizes Venus. Enact governments on Venus.

I like the idea of floating towns and cities about 50km above the Venusian surface. Residing on one of these islands in the sky and feeling almost like a deity would surely best living in a lunar bunker!

Why do these ideas always involve producing more graphene than we could ever know what to do with? We have another method of taking care of all that CO2, and one that I think produces something much more important. 6CO2 + 6H2O + energy ------> C6H12O6 + 6O2 Lucky for us, we don't actually need to supply that energy, as this reaction readily takes place with just the energy provided by the sun. I think sugar and oxygen are both good things to have, considering you need both to live. No machinery is needed for this reaction either, in fact, all you need to bring along is some seed material. Of course by now, I'm going to assume readers have figured out I'm talking about photosynthesis. it has other benefits too, depending on how large these dirigibles are, you can farm something like sugar cane or sugar beets to get nearly pure sugar, and you can turn that into biofuel to drive around with, or to propel the whole blimp with. growing a crop like rice, you can harvest the methane it produces to generate electricity in the event that we can't get enough solar panels to Venus. It's almost an ideal greenhouse environment.

***** The biggest problem with Venus is that 90% of terraforming it is getting it so that it's safe to live on the ground there. This is perhaps the biggest advantage of both the Moon and Mars. There, you can build big greenhouses and grow your plants in (fertilized) regolith. Indeed, the photosynthesis will probably provide much of the colonies' oxygen. From the geological record, we know that, with plenty of time, algae photosynthesis will render an inhabitable planet. The big problem here is that we don't want to wait for a geological era to pass before Venus is inhabitable. On the other hand, if the Moon and Mars need carbon dioxide, and Venus's biggest problem is it's got too much carbon dioxide ... hmm ... opportunity much?

Why not just crash a giant asteroid into Venus. We have had several ice ages due to meteors hitting the Earth. The one that wiped out 90% of life and the Dinosaurs at the end of the Cretaceous period was only 10 miles in diameter. Perhaps several that size should do it. A comet or 2 containing ice may be another great idea. My science teacher in high school said something I remember. If only Mars and Venus swapped orbits. Mars having a thin atmosphere and not able to hold much heat would benefit being closer to the sun. Venus with a very thick atmosphere could be twice the distance from the Sun as the Earth. That would make terraforming much easier. We could then be a 3 planet species. 4 if you count the Moon.

But there was a ice age or freezing and darkening of the skies after the meteor 65M years ago. The reptillian life mostly died out. (Depends on which science journal you read. But the time of the dinosaurs it was 14 degress warmer)It's kind of like a nuclear winter with cooling of the planet. But there have been many known ice ages that have come and gone. Some due to huge asteriods. Some with Polar Shifting and orbit wobble. There are also times when the oxygen ratio was down to less than 12% and as high as 35%. The same as Carbon dixode level it has been 2-3 X higher than today in the 7 billion human industrial age. And there have been times where carbon dixode was almost non existant so plant life struggled.The Suns heat generation is not like a light bulb that is constant. There are times where more heat is made. Like when there is little or no sunspots. There are of course many other variables. So if you had all the variables on the colder end. You would have a frozen planet. The temp here on Earth also has times where it was 2-3 degress warmer as in the roman times and again in Viking. But colder as in the 16th and 17 centuries.

Later, the oxygen collected can be re-introduced. What do you think?

While Mars on the other hand, eventhough it's small in size, is the best candidate terraforming, by increasing the amount of greenhouse gases to warm the planet up, also they have to research about the plants that could grow in a martian environment to produce oxygen. Thus, Mars had water on it's surface frozen for many years, and it has to be melted in a reasonable amount of greenhouse gases to warm it up.

Terraforming any planet is a generally narrow-minded idea because it ignores the fact that every planet evolves according to its particular natural characteristics, such as the distance from its star, chemical composition, gravitation, rotation, etc. Before considering interventions in a planet's natural systems/ecology, we should first work to understand the paths energy takes through it. Once you have a full grasp of how energy is absorbed and expressed by a planet, you can consider what effects interventions in that planet's natural systems will have. You may still make mistakes or overlook things, but you should at least try to make sense of the system as it exists, along with any potential changes you would make, before pressing forward with the will to colonize, terraform, etc.

Whatever volcanoes or other energy events occurred on Venus to make the system as it is now; those cannot be undone. It will be the same on Earth if there is total desertification due to climate warming or total nuclear holocaust, etc. Any planet-altering energy event would drastically change the patterns of energy flow through the gravity well. Those life forms that are able to survive within the new energy patterns will survive and evolve to greater levels of complexity and/or profieration; while those that can't deal with radical environmental change will go extinct. Whatever forms of life were evolving on Venus before its current state must have been wiped out by the kind of volcanic eruptions and runaway greenhouse effects you describe, but new life forms must be nascent and/or evolving within the stabilizing patterns of energy dissipation occurring there now. With current technologies, we have the choice to allow natural systems to maintain whatever stability they are settling into or introduce a new event of radical destabilization in the hope of controlling the aftermath to our own benefit. Since humans are not that good at foreseeing the long term consequences of our incredible powers; it is wise to limit interventions in natural systems as much as possible, making exceptions only when a clear and present benefit is known to outweigh all the potential consequences of our actions.

On Earth, higher temperature environments are typically more robust with life, e.g. rainforests. Hot deserts might be an exception because humidity has fallen below the level that can sustain robust life, but we also don't know how much of that energy is brewing life underground. We are only familiar with water-based life, i.e. life where chemical reactions take place in aqueous solutions. Life on Mars, Venus, or elsewhere might involve very different chemical reactions. Venusian life might even involve plasma and occur in short life-spans. Earth life also involves plasma-like molecular behavior, but because the molecules are ionizing and re-combining within an aqueous solution, they are relatively slow.

Venus also has one significant advantage compared to Mars; Going there for an extended period of time isn't a one-way trip. If you send crews to terraform Mars, you're basically sending them there for life, with their bodies adapting to low gravity. But when you want to terraform Venus, you can send people there for 10 years at a time and they'll return to earth just fine (they'll just feel 10% heavier). You would work on Venus similar to how people work on oil rigs. It's hard work far away from home, but if it pays well enough, you can attract skilled workers. When it comes to terraforming Mars on the other hand, you are limiting yourself to people who want to leave earth for good. Which might not be the people you want for this job.

The key of terraforming Venus is to speed the rotation. It probably has a liquid metallic core, like Earth, but it lacks a magnetosphere due to the lack of rotation. Probably if we managed to make it spin like Earth, the crust will crack and plate tectonics will appear. All the sulphuric acid probably comes from the reaction of the sulphur dioxide expelled by vulcanos, combined with the water it once existed, most likely.

Venus rotates retrograde (probably because of a physically inversion of its axis) and the solar winds fight its rotation which has slowed it down eventually halting and maybe reversing if the internal pressure doesn't blow up first. I think getting the rotation to correct itself would restore the geomotor of the the planet. Restoring the geomotor would protect the atmosphere and the planet would cool down once the the internal energy is dissipated by restoring the magnetic field. How do you restore normal rotation?

The formation of H2O could result in a liquid form, such as oceans. The carbon could be in a solid state, maybe used in some type of hydrocarbon structure, or even plant life? The plant life and the oceans would tend to stabilize the planets temperature. The atmospheric pressure would drop greatly because what was a gas now is a surface liquid or solid.

I'd say terraforming Venus would be significantly more beneficial than terraforming Mars, mainly because it is so similar to Earth in many characteristics. And it's much closer. We just need to figure out how to deal with that pesky carbon and transform CO2 into H2O and O2 and fixate Carbon into the crust of Venus. Those floating cities could be the main catalysts of such process: maybe giant vegetation units with plenty of plant and microbial life that could be deposited down to the surface upon death (not only fixating carbon but also creating first layers of humus and mold) Then, we'd need some orbital bombardment Warhammer 40K style to try and speed up Venus' rotation (maybe that should be before the decarbonization process). Finally, to deal with magnetic field we'd either need some insane tech that could start up the core and make it spin for magnetosphere generation or create giant orbital filters that would block high energy radiation of the sun and let similar composition solar energy that reaches Earth to reach Venus. Tech like this won't come in another 100 years however, so hope there will be cheap ways to extend life in upcoming 50 years.

A venus mars trading route would be interesting. Raise the grade some and then send the rocks into the inner system so they can be worked on by foundries that have access to the higher energy densities that are available on venus and mercury. A thin dyson sphere made of carbon is interesting that the floating cloud cities would eventually suspend from until the atmosphere is thin enough for terraforming.

I think to actually terraform Venus would require all different solutions simultaneously working.

how about scrubbing the antmosphere free of C02 and placing large rockets strapped to the equator of venus and then rev them up to max, the rockets could perhaps be nuclear rockets that convert the mass of the carbon into energy to speed up its rotation?

I wonder how much time it would take to cool the planet down. Problem to terraforming is that it would take a lot of time. I wonder if it would take more or less time doing this or travelling to another planet. Travelling faster for 10,000 years seems almost a easier breakthrough to acheive.

So Martians on earth would have a hard time walking around, standing, and even existing. Secondly, Venus is on average closer to earth than mars, so getting there would take less time, as well as the launch window for traveling to Venus would come around quicker than Mars's launch window. Venus is also bigger than Mars, meaning it can house more people. Venus receives more light than mars, meaning plants would grow faster, Mars dose the have much of an axial tilt, so it could be eternal summer weather in one place, eternal spring/fall weather on another, and eternal winter weather nearing the poles.

***** Solar wind mostly does this to hydrogen, which is very light. That is why Venus has almost no water, which is H2O. This is from Wikipedia: “The water has most probably photodissociated, and, because of the lack of a planetary magnetic field, the free hydrogen has been swept into interplanetary space by the solar wind”. Carbon and oxygen in CO2 are much heavier than hydrogen.

Highly absorbent nano tech blocks that absorb co2 and bind it in the block. When block is saturated the nano bots build another block... Then all the co2 is in the blocks which you spend many years removing from the surface. The planets rotation is a problem though.

My summerhouse plans for venus: 1a) we need to be able to make 'balloons' from co2, automatically, in such way that the made 'balloon' can reproduce. (there exists levels of that atmosphere at about 20c and 1 atm) No real need for a step 2 then but if we want a surface. By these balloons covering the face of venus the rest of the atmosphere would sublime and we need to do something with it. I would prefer containing it in some chemical more stable then co2 or lifting it to space, if we get a mater teleportator we just send it to mars. Then 2-3 things left: rotation, water and electric field. I have a hunch that venus lacks magnetic field not to solid core but the lack of rotation, the dynamo is practically at rest, in that case 2 things. Which I would solve be crashing some comets, or icemoons or something at an angle, giving momentum ( i know it may take some comets)
