Can humans migrate to other planets?

Now people ask: Can humans move into space? Experts say that human beings need at least three conditions to go into space:

One is to have powerful means of transportation. At the beginning of the 20th century, Russian scientist tsiolkovsky proved theoretically that under the industrial and technical conditions at that time, it was impossible to reach the speed of the universe with a single-stage rocket, and it was necessary to relay into space with a multi-stage rocket. Now, many manned spacecraft, space shuttles and space stations have been successfully developed and launched in the world.

The second is to develop manned spacecraft that can imitate the basic living conditions of the earth. There is no oxygen in space, and the temperature is extremely low. When an object is irradiated by the sun, the temperature will rise rapidly, which is beyond human capacity. In such an environment, people can't survive. Therefore, the spacecraft should have many special systems with suitable air composition and temperature to meet the life and work needs of astronauts. The former Soviet Union/Russia, the United States and China launched unmanned spacecraft to carry out related experiments and achieved some results.

The third is to understand the influence of space environment on human body. After long-term research, scientists have found that the special space environment has a great influence on the human body. When human beings enter space, due to the lack of gravity downward attraction, all body fluids are transferred to the upper body and head. The transfer of body fluids will reduce the volume of plasma and concentrate blood, leading to anemia. Meanwhile. Microgravity environment will also have an impact on human muscles and bones. There are also ultra-low temperature, strong radiation and huge acceleration and deceleration during the take-off and landing of spacecraft, which will have extremely harmful effects on the human body.

With the development of space technology, the improvement of space environment and technical awareness, human beings will make more and more achievements in the space field, some problems will be solved step by step, and the dream of human beings going into space will finally come true. (End)
