Can humans transform Venus into a second home?

Venus, as one of the eight planets in the solar system, is the most similar planet to Earth among the four terrestrial planets. Scientists even think that hundreds of millions of years ago, the environment on Venus was almost the same as that on the earth now.

Venus and the earth have similar conditions, that is, the size, structure and gravity are similar to the earth; Minerals are the same as the earth; Venus cools at the same rate as the earth, and its interior does not cool and solidify like Mars or the moon. At present, there is still a weak magnetic field, which shows that Venus is not dead and can also protect Venus from cosmic rays.

In addition, Venus is the closest planet to the Earth, with a short round-trip landing time, and various logistics costs are much cheaper than Mars. Moreover, Venus is not as close to the asteroid belt as Mars and is rarely hit by asteroids. Relatively speaking, it is relatively safe in the process of transformation.

However, at present, it is very difficult to transform the environment and conditions on Venus. The first thing human beings face is high temperature and high pressure. The temperature on Venus is about 450 degrees Celsius, which can melt metals such as lead. If people go up without protection, they won't live for a few seconds. In addition, the atmospheric pressure on Venus is 90 times higher than that on Earth, which is equivalent to the pressure on the seabed 1000 meters. This kind of pressure is unbearable.

The main reason for Venus' high temperature and high pressure is a large amount of dense carbon dioxide. The thick atmosphere on Mars is filled with 99% carbon dioxide. So much carbon dioxide must be pumped away. Humans must make enough gas pumping equipment and send chemicals into the atmosphere of Venus to change the atmospheric composition.

Or use carbon dioxide to produce substances that humans can use, such as artificially synthesizing starch with carbon dioxide.

These devices can only be deployed in the outer atmosphere and near-earth space of Venus, but the transformation of Venus' atmosphere may take a long time, estimated to take hundreds or even thousands of years.

Only when the carbon dioxide in the atmosphere of Venus is reduced to a certain extent, the greenhouse effect is further reduced, and the temperature and pressure on the surface of Venus are reduced, can humans land on Venus.

At present, there is no water and oxygen on the surface of Venus, which is a huge obstacle. Unlike Mars, which has a lot of groundwater, some scientists have put forward a bold idea, that is, dragging the icy objects in the asteroid belt to bombard Venus to replenish the surface moisture of Venus.

As long as there is water on the surface of Venus, the problem of oxygen will be solved. Humans will send a large number of electrolytic equipment to Venus to decompose water into oxygen and hydrogen, so that the oxygen content in Venus' atmosphere will gradually increase. After reaching a certain level, people can live on it.

There is still a big problem in the transformation of Venus, that is, how to strengthen the magnetic field of Venus, because the magnetic field of Venus is quite weak at present, which is not enough to stabilize liquid water and the atmosphere. Then we must wait for the progress of science and technology to strengthen the magnetic field of Venus.

After the transformation of Venus' atmosphere is completed, there will be enough water and oxygen. Finally, Venus is afforested to form its own benign ecological environment. After forming an environment suitable for human habitation, you can immigrate to Venus on a large scale.

Some scientists believe that it is feasible to globalize Venus. One day, it is really possible for human beings to transform Venus and make it their second home.
