How Hard is the Work of Astronauts?

Compared with space, the earth is actually a very safe home. On the earth, we can breathe air freely. Under the protection of magnetic field and atmosphere, can we survive naturally without cosmic rays and under the sun's irradiation?

But in order to explore the universe, our astronauts went into space one after another, only to improve our information about space. In our imagination, they always wear a white spacesuit, wear a space cap, have the highest honor, and constantly contribute to human exploration.

It's not easy to train an excellent astronaut. First of all, these people are selected from the elite troops of various countries. Their physical function and psychological quality are the first conditions, and the air pilots are the priority of astronauts.

We know that there are a lot of space viruses and cosmic radiation in space. Space suit caps can isolate and protect our human body from these attacks. As for water and oxygen cylinders, compressed food is for our body needs, and guns are for the prevention of unexpected events when landing on the ground in space.

Astronauts also have a lot of unknown precautions, that is, if astronauts die in outer space unfortunately, they can not return their bodies to Earth. Because of the environmental reasons in outer space, if their bodies are brought back to Earth, it will cause a huge disaster spread by space virus crazily, and seriously may cause the extinction of life on Earth.
