How feasable would it be to build a flotilla of robotic vehicles and send them to the Ort cloud to pick up ice (comets) and guide them to crash in Venus? Assuming that only a small amount of energy is required to push an ice chunk out of its orbit out there.

No, there is no water on Venus, water vapor perhaps but not enough to make oceans. Yes this will take a long time. And the water is needed to dilute the acid and cool down the planet.

How can this be done?

2006-09-22 08:31:29 · update #1

The acid is suspended in the atmosphere.

2006-09-22 08:33:06 · update #2

I like the bateria idea. And no, water is not a green house gas. And yes, the idea of the water in the atmosphere is to mix with the acid.

2006-09-22 09:25:20 · update #3

Water vapor might even reflect some to the Sun heat back to space cooling the planet.

2006-09-22 09:28:55 · update #4

How much more heat can water vapor add to an atmosphere with an ave temp of 900 F?

2006-09-22 16:08:19 · update #5

Don't think of reasons why it wouldn't work but how can we make this work. Yes, it will be expensive and yes it will take a long time.

Still like the bacteria idea, I don't know how algae can be suspended in the air though.

A proposition is to seed the planet with bacteria that reduce the sulphuric acid to Sulphur, Oxygen, and water and and the carbon dioxide to Oxygen and Carbon. The temperature then would drop dramatically. It might be habitable on the mountain tops. But. the pressure would still be a huge problem.

As was said above, any water brought to Venus would quickly vaporize, and water vapor is a greenhouse gas. If you want liquid water on the surface, you need to cool the planet off first. To cool it off, you'll need to get rid of much of the carbon dioxide atmosphere to reduce the greenhouse effect on the planet. Once you do that, you need a way to keep water vapor from building up in the atmosphere, since it will still be quite hot on Venus.

As for picking up comets from the Oort Cloud, I think you'd be better off getting comets from the Kuiper Belt. Even then, in order to get them to come into the inner solar system and crash into Venus you would essentially need to stop them. A comet with a distance of 100 AU (100 times the distance between Earth and the Sun) would have a speed of 3 million meters per second. Stoping something moving this fast would take more than just a small amount of energy (especially since kinetic energy goes as speed squared!).

YES, water vapor IS a greenhouse gas - that's why cloudy nights are warm, and clear nights are cold. Go review your meteorology!

First, we'd need to get rid of much of the carbon dioxide in the atmosphere. This is a rather simple task; one must simply seed the atmosphere with algae then sit back and wait. Then we can use comets from the Oort cloud to add water to the equation.

There are two enormous problems with this, however. Firstly, time: terraforming Venus like this will take millenia, and when it's over, we may well have forgotten all about it. Secondly, cost: effectively deorbiting a comet and guiding it into Venus would take a prohibitive amount of fuel, to say nothing of the fuel required to actually get the engines to the comet in question.

In short, it is possible, but by no means feasible.

Venus is so hot because the atmosphere is very dense and full of the greenhouse gas carbon dioxide. Adding water would not only not cool it down, it would heat it up more, since water vapor is a more powerful greenhouse gas than carbon dioxide. At the temperature of Venus no water would ever condense to a liquid, it would remain a vapor all the time.

you may desire to kick back it down. some thing to thoroughly block the solar from all the planet for some a protracted time could be a initiate. moving Mercury right into a geostationary orbit between Venus and the solar may well be a initiate. including water isn't a answer, because water is a greenhouse gas as steam. besides, the kinetic power of an ice asteroid miraculous Venus could be converted to warmth. Get the persons from Stargate to establish a stargate on Venus with the different end on Mars and circulate area of the ambience over. as quickly as Mars has adequate warm CO2, despatched something to Jupiter, which in all probability won't word some trillion an awful lot greater gas. Now you have that environment thinned down, speed up the rotation of Venus so it rather is a few thing in the area of 20 - 30 hours like Earth or Mars. all of it sounds extremely costly. greater low-value to establish camp in the midst of the Sahara.

Extremely infeasible. Considering that Oort cloud objects orbit at roughly 100,000 AU, the incredible duration of the project would itself be prohibitive. In addition, it's unnecessary because Venus' thick atmosphere could quite possible be partially converted into water.

Not really. Im sure there is water on Venus and that is not the problem. Pressure of surface plus atmosphere is to full of Sulfur. Not to mention the acid rain. We cant even put a probe on Venus w/o it becoming dust after a few minutes.

Not to feasible. What would be the point?
