Interstellar migration reality

Water is being produced on the surface of Venus, which produces the atmosphere needed for life and tends to be covered by water. The surface space of Venus has begun to produce organic matter. The temperature of the sun is 140℃, which is close to 400℃ because there are many solidified impurities in the space, but it is only 2℃ below the ground 10m, and the temperature can be reduced to about 20℃ in temperature-resistant buildings, which is suitable for the survival of life under the stratum. Farming can be carried out in the temperature-resistant floor. There is water in the valley, and the water source is increasing, so there is no shortage of water. In the future, when it is covered with water, high-rise buildings can be built to make life more likely to continue. Venus is moving away from the sun at a speed of 30 meters per year. It is the closest planet to the earth and the planet where life lives.

Venus is located in the inner edge of the livable zone of the solar system, and its diameter is slightly smaller than that of the earth, but its surface environment is extremely bad and it is not suitable for human habitation. In the early days of the formation of the solar system, the environment of the earth and Venus was very similar, but early organisms such as cyanobacteria appeared on the earth, which improved the atmospheric environment of the earth and controlled the carbon content in the atmosphere to a certain level; On Venus, on the other hand, the carbon dioxide content is completely out of control. At present, the carbon dioxide content is as high as 96%, which has triggered the global greenhouse effect.

After the sun shines on the surface of Venus, the heat is stored in the atmosphere. At present, the average surface temperature of Venus is as high as 460℃, which is enough to melt metal lead. The pressure is as high as 90 atmospheres, and there is strong acid rain all over the sky. Several probes of the former Soviet Union landed on the surface of Venus, all of which were completely destroyed after running. The most important chemical element for life is water. Under the surface conditions of Venus, water has become supercritical, and its chemical properties have become very active, so it is impossible to help life.

With the current level of human technology, it is still impossible to improve the atmospheric environment of a planet, but for an extraterrestrial planet like Mars, human beings have the ability to establish a Mars base, establish human settlements in a small area, and gradually realize interstellar migration. The United States also has such a Mars program in this century.
