How would we go about making venus liveable? what are some ways to terraform venus?

Question

what would one need to live on venus

Answer 1

This is a great question! Any solutions we find to the terraforming of Venus would be great practice for restoring Earth.

Answer 2

Although Venus would seem to be a likely candidate for terraforming, it would probably be immensely difficult, and certainly beyond our current technology.

Venus is nearly the same size as Earth, and so the surface gravity is 0.95 G. However, the atmosphere is very different.

Venus' atmosphere is 95% carbon dioxide (Earth's is mostly nitrogen, and only 0.04% carbon dioxide). This much carbon dioxide creates massive greenhouse trapping of heat, and the surface temperature of Venus is around 450 C (hot enough to melt lead). Plus, there's so much of it, that it creates 95 times the atmospheric pressure of Earth's atmosphere. On top of that are clouds of sulfuric acid and rains of molten sulfur that make life (as we know it) on Venus highly unpleasant.

We would need to reduce the atmospheric pressure (which we have no easy means of doing), bind the carbon dioxide into a non-atmospheric form (which would require a LOT of binding), somehow reduce the temperature (which might come on its own once we start binding the CO2), and then figure out what to do with the various toxic and acidic sulfur compounds in the atmosphere.

Once all that was done, we could maybe look at trying to develop oxygen and water content on the planet.

It would probably be easier to look elsewhere, even in other solar systems, for more suitable planets, or even construct our own space habitats rather than terraforming the hellish Venusian atmosphere.

Answer 3

Just block out some of the sunlight.

Although Venus atmosphere is dramatically different from earths they were practically identical in their youth. Venus is truly earths twin. Venus just hung around with the wrong crowd...

The only thing that made Venus so different from earth is its proximity to the sun. But if you could reduce the amount of sunlight that falls onto Venus, 88%, Venus would get as much sunlight as earth does and would begin to transform into earth.

As the atmosphere cools down first the sulphuric acid in it would begin to rain down on the surface. Currently it is too hot for it to do so. As soon as the acid contacts the soil it will react chemically with minerals in it to form sulfate rock and water. As sulphuric oxides are a potent greenhouse gas as soon as the atmosphere is depleted of sulphur it will begin to get cool enough for water to condensate. And when actual rain begins to fall the most important process will begin. The transformation of carbondioxe into carbonate rock.

Carbondioxide dissolves rapidly in liquid water. With dissolved oxides from the soil also in the water solid carbonates will immediatelly begin to form. And because the water isn´t consumed in the reaction (cathalyst) it will continue to transform carbondioxe into carbonate rock for as long as there is either the oxides in the soil or carbondioxide is the atmosphere. So Venus atmosphere will get thinner and thinner. This process happened on earth too long ago. It is actually still going on. If it weren´t for earths geological activity, which constantly spews co2 into the atmosphere, earth wouldn´t have an atmosphere at all. It would take a while but eventually Venus atmosphere will be thin enough and cool enough for humans to go there. And we could possibly artificially accellerate the process.

But how to keep the sunlight away in the first place? Well between all two bodies of mass there are 5 points where their gravity cancells each other out (LaGrange points). So too with the sun and Venus. One of those points lies right inbetween Venus and the sun. For all sence and purposes it is a fixed point. If an object would be placed there it would remain there. So that is where you build your sunblocker. It would have to have the diameter of Venus itself but if you build it in a grating array out of solarpanels you would have some interesting byproducts. Such as all the electricity humanity will ever need. And you could also run some of that power around the circumference of the array to generate an artificial magnetosphere to protect Venus further from the raging sun.

Forget about Mars. Let´s go terraform Venus!

Answer 4

Moving to other planets is far from our next logical step in expanding civilization.

LONG before we need to move to other planets, don't you think it would make more sense to explore and colonize our own oceans and large lakes? After all, water covers 2/3 of the planet, and we don't currently live there. That is probably the next step in our colonization (though the rate of population growth is actually decreasing worldwide!!).

Next, why would we not want to colonize the moon? It's conditions are FAR closer to those of earth compared to Mars or Venus.

Either way, though, the natural resourses that support life are not found anywhere in the known universe except for here, so we better focus on taking care of this planet instead of relying on any other ones!!

Answer 5

Re-direct some large comets to bring in water would be helpful. Deploy enormous solar screens to cool down the planet and counteract the greenhouse effect.
Even if we had the technology, it would take centuries or milenia.

Answer 6

in case you will detect a stable thank you to terraform Venus, NASA would be maximum fascinated in having you come over for lunch and function a talk with their scientists. to confirm you don't get misplaced on the way out of your place to NASA HQ, a set of courtesy escorts in armoured autos, donning black physique armor and donning tags with the label 'FBI' will in my opinion determine you get to NASA HQ devoid of taking a incorrect turn on the expressway.

Answer 7

May I direct your attention to the "Genesis Project " from Star Trek 3?

Answer 8

Virtually impossible. We'd have to get rid of it's atmosphere and transport ours there.
