Problems with terraforming other planets
Can we someday terraform other planets? Sometimes people are thinking that terraforming would be processed, where the bacteria would be delivered to the atmosphere, and then the terraformation starts immediately. The major problem is that if the planet's gravity will be too weak, the atmosphere would escape to space.
The reality in this kind of process is that the bacteria, what is delivered to the atmosphere of some other planet would be dead immediately if the temperature or level of ultraviolet radiation would be too high. And also the bacteria must be something, that produces or releases oxygen to the atmosphere.
When we are looking at the writings, what are made about the terraformation there are two examples of planets, which could be terraformed in the future. At this point, I must say, that the terraforming process would be extremely difficult and takes hundreds or even thousands of years to terraform Mars or Venus.
I) Terraforming planet Mars
One of the most often mentioned target for terraforming planet Mars is a more tricky thing than many people expect. The weak gravity and low pressure along with a weak magnetic cause that stabilizing the atmosphere is extremely difficult.
So the terraforming the planet Mars could happen by using large-sized greenhouses. But the terraforming planet Mars by using the methodology, which allows colonists to walk outside the base without space suit is impossible. The ultraviolet radiation would destroy the water molecules and the solar wind would just blow the atmosphere out to space.
II) Terraforming planet Venus
Terraformation of Venus is a more promising idea than terraforming Mars because there is lots of oxygen in its atmosphere, which is mainly the carbon monoxide (CO). But first oxygen must be separate from the carbon atoms. Clouds of the planet are forming by the sulfur acid (H2SO4), which is the corrosive thing. Sulfur acid would also involve the hydrogen, which is necessary for releasing water to that area.
The temperature of that planet is extremely high, about 500 degrees Celcius, and there is no water, which makes it very hostile. The cells cannot live in that dry and hostile planet, but the thing is that terraforming Venus could be possible if we would make a couple of tricks with that thing. One version is to drill the cell cultures in the basalt stones of Venus, where they are safe from the temperature.
IIB) Chemical separation of carbon and oxygen.
The chemical separation of carbon and oxygen can be done by using the capillary tubes, where is the carbon filters. Also, carbon dust can deliver to the atmosphere, which would reduce carbon and release oxygen. This kind of system is easy to produce and the real problem is just how to get those tubes to that planet. Then the pressure would pull the air through that tube, which will release oxygen to the air. Also, lime can be released to the atmosphere and that would neutralize the sulfur acid.
When the chemical separation of the oxygen to the atmosphere of Venus has been continued enough long, the hydrogen would pump to the Venus atmosphere, and then the electric circuits would burn the hydrogen. The result of burning hydrogen in that atmosphere causes that the water starts to form on that planet. Sometimes theorists have thought that the ionized hydrogen that is captured from the space would be driven to the atmosphere of the planet, and then the large mass of water can be formed by burning the hydrogen in the atmosphere.
So the problem is how to make enough water that it can turn Venus the new Earth. And the second problem is that creating enough oxygen to the atmosphere that the large scale creation of water is possible would take a very long time. And the rotation speed of this planet must be increased because that allows that the sunlight would point smoothly to the entire planet.
