The word "terraforming" was invented by visionaries in the first half of the last century. It means a change in the landscape and the climate of another planet in order to create conditions for the life of terrestrial organisms. It sounds really fantastic. But modern science terraforming has become an accepted term. After all, with all the grandeur of such plans, technologies to "remake" of the planet at will, already exist. Typically, the role of the first to colonize the territory considered cold and inhospitable Mars. Let us recall the very apple. However, some scientists believe that it is much better suited for terraforming another neighbor. And it is - Venus. In size it is almost equal to the Earth. Slightly lighter and slightly smaller in diameter. Unlike Mars, it has a sufficiently dense atmosphere. But here and difficulties begin, because the atmosphere is 97% carbon dioxide, and oxygen and water on Venus is almost there. The pressure on the surface 93 times the earth. And the average temperature is about 467 °. Could it really possible to conquer the beautiful and inaccessible Venus? Consider the process of terraforming the second planet from the Sun, step by step. The first thing to do - to lower the temperature. To do this, between the Sun and Venus will establish special screens of colossal size. They should reduce the 30% intensity heating surface and protect it from the solar wind. Because of the sharp drop in temperature, most of the carbon dioxide immediately falls in the form of dry ice, as a result - significantly reduced atmospheric pressure. The next step - the creation of the magnetic field of the planet. There are two ways. The first looks unrealistic even for problems of this magnitude - the planet we have to somehow further unwind. How long it will take the energy - it is difficult to even imagine. The second way - too energy-intensive, but it is implemented. On the equator of the planet stretched electric wire and let on it current. It will act as a kind of coil. Was the result of this magnetic field is quite able to defend the planet from cosmic radiation, which have not been allowed to exist here water molecules. And then you can start to colonize the planet. However, the first colonists will, most likely, not people, and the blue-green algae -kosmicheskie pilgrims. One of the ideas further terraforming Venus - spray these creatures in the planet's atmosphere. They will break down carbon dioxide, filling it with oxygen. However, the same task can handle and artificial self-replicating machines. This technology also does not seem fantastic. Now, where to begin, perhaps, the most difficult and crucial stage of transformation of Venus. Planet literally hurl asteroids. For example, the asteroid Kleopatra will help get rid of the sulfuric acid in the atmosphere. After all, it contains a large number of metals that react with the acid and lead to neutralize it. But most of the space objects that are scheduled to "reset" on Venus, to bring her water. The fact is that the creation of the hydrosphere requires 10 tons of water 17 degrees - it is comparable to the volume of the Earth oceans. Therefore, the resources of our planet is clearly not enough. At the same time, even if in space and managed to find an icy asteroid desired size, he could just kill Venus. So, throwing the planet have small particles of cosmic dust. Resulting from orbital bombardment reservoirs will erode the planet's surface, releasing minerals. Those, in turn, will react with the hydrocarbon residues of sulfuric acid and finally converting the earth's atmosphere. All about everything from mankind, in all probability, it will take more than one hundred years, and more than one hundred trillion dollars. But the long-term investment will pay off. Not somewhere in the constellation Cygnus, and literally next we get a new house with an average surface temperature of about 26 ° - such utter planetary California. So what is most interesting is yet to come.
