The Technology Tree of Xueba

On March 5, Hainan Wenchang Space Launch Center launched a spacecraft again.

The five astronauts replaced the three astronauts, Du Long, Kong Deyang, and Wang Tong, who had been working on the space station for more than half a year.

Huaxia media followed up and reported on the replacement of astronauts. This is the first time Huaxia has rotated personnel on the space station.

At 5:00 pm on March 6, as the huge spacecraft landed at the designated location, the three astronauts officially returned to Earth.

The three astronauts just waved their hands at the camera after leaving the cabin and said hello.

They were rushed to the Xinghuo Technology Medical Laboratory by the flying car.

Chen Jin, Wang Xiaoxiao and well-known medical experts sent by the country began to conduct detailed physical examinations on the astronauts.

They have lived in the space station for more than half a year. This is to test the specific changes in human health when the human body lives away from the ground for a long time.

Zhou Yu saw that the three astronauts looked a little nervous. He knew that anyone surrounded by many doctors in white coats and doing all kinds of unexplained examinations would feel nervous.

He quickly comforted: Don't worry, it's not because of your life in space that your body becomes diseased, and your life on the space station will not leave you with the root cause of the disease.

We are collecting the changes of your cells. The human body is very adaptable. If you live in a certain place for a long time, your cells will change according to the environment.

If you find the law of cell changes, you can effectively target it and make more comfortable arrangements for the life of astronauts in the future.

With a heroic expression on his face, Du Long gritted his teeth and said, Please rest assured, my ideological consciousness is very high, even if I donate my organs, there will be no problem. Please check my physical condition carefully.

Listening to what Du Long said, Song Ning, director of the astronaut training base, explained in a gentle tone: You really don't need to worry, this is just a routine inspection, and every astronaut must perform this inspection procedure after returning.

If you really have a problem with your body, we will also inform you truthfully.

A thorough examination can also effectively prevent the body from being delayed by the disease. If you really don't suffer from certain diseases, everyone is not happy.

Authoritative doctors and biological scientists began to conduct detailed inspections on the bodies of the three astronauts, from the state of genes to the state of cells, from the functions of organs to the coordination of human body systems, without any mistakes.

On March 8, Zhou Yu, Feng Hai, and Song Ning listened to the inspection report of the astronauts.

Chen Jin was in charge of reading to them the report written by hundreds of authoritative experts after thorough examination and cooperation.

From a medical point of view, the bodies of the three astronauts are healthy, and they do not suffer from any disease.

After Song Ming listened, his expression relaxed. In fact, he was very nervous because he was afraid that the astronaut would suffer from an irreversible serious illness.

He trained these astronauts and watched them work hard for China's aerospace industry.

While contributing to the country, he also suffers from certain diseases, which would make the hero very sad.

Astronauts live in the space station for a long time, and if they really suffer from certain diseases, it will also have a major impact on the aerospace industry.

The booming aerospace industry may be cast a shadow because of this discovery.

The three astronauts are just not physically sick. They have lived on the space station for half a year, and their bodies have also undergone some changes.

The astronaut training base has detailed inspections on the astronauts, and we have obtained their health information living in the astronaut training base.

Through the comparison of these materials and their current physical conditions, some problems in the astronauts were discovered.

Chen Jin's words raised everyone's worries again. They are waiting for Chen Jin's specific conclusion.

The human body is really fragile. The bodies of the three astronauts are all excellent. After living in the space station for half a year, some slight changes have taken place in their bodies.

The red blood cells of the three astronauts have mutated, and the efficiency of red blood cells to transport oxygen has been accelerated.

Astronauts are in a vacuum and use space suits to supply oxygen.

Oxygen produced industrially must be different in composition from air.

We just try to adjust the ratio of carbon dioxide and oxygen, and fill some nitrogen and water vapor as supplementary ingredients.

The human body has sensed the lack of oxygen in the astronauts, and the red blood cells began to speed up the transport of oxygen to various tissues.

This caused certain organs of the astronauts to become oversaturated with oxygen, which appeared to be a little hyperactive to the outside world, but the lifespan of the cells that make up their organs was not as long as that of normal people.

The genes of the three astronauts were normal, and no special mutation occurred.

However, the cancer cell production rate of the three astronauts was five times higher than before. Fortunately, their immune systems were fine, and all the cancer cells they produced were killed by the immune system.

Because of the lower gravity of the space station, the bone density of the three astronauts decreased.

It will not affect the body now, but if you live in an area with lower gravity than the earth for a long time, your bone density will continue to decrease.

In the end, the bones cannot provide effective support for the body, the organs may be damaged, and fractures may occur after a fall.

When Zhou Yu heard Chen Jin's introduction, he was not surprised at all, and said: We can predict these effects before, and scientists have made perfect explanations.

This is because the human body's ability to adapt to the environment is too strong, which will lead to these problems.

This phenomenon cannot be effectively solved now, but this is only a problem that needs to be solved in the future, and these changes are not enough to affect the development of the aerospace industry.

Chen Jin looked at the report in his hand again, and said with a heavy tone: You may have expected this, and you won't be surprised by it, it just proves that our human body is very fragile and completely unsuitable for living in an environment other than the earth.

Even some extreme environments on the earth are unbearable for most people.

This time, our experts discovered problems that European and American scientists had not discovered or that they had not announced through the joint detection method of genes and cells.

Astronauts have lived on the space station for half a year, and their bodies have been unable to differentiate qualified germ cells.

The activity of germ cells in their bodies is extremely low, and it is impossible to form embryos at all.

Based on the physical analysis of the astronauts, our scientists found the specific cause of this problem, which is the stress response of the astronauts' bodies.

In this state, people are unable to reproduce.

But this is a reversible mutation, as long as it lives on the earth for a period of time, it will recover.

Feng Hai said nonchalantly: This kind of problem is not a problem at all. Astronauts are for work, and they are not allowed to fall in love. No one would give birth in the space station.

Chen Jin waved her hand and said seriously: Other problems are small problems, and this kind of problems are big problems.

Are we just living on a space station, and will land on the moon and Mars in the future, or take a spaceship for interstellar voyages.

It is necessary to ensure the normal reproduction of the population in order to stabilize people's hearts.

We can't rely on human cloning to develop the universe. This kind of thing should be discovered and solved early.
