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

Five astronauts replaced three astronauts who have been working in the space station for more than half a year, Du Long, Kong Deyang and Wang Tong.

Huaxia media has comprehensively followed up on astronaut replacement, which is the first time that China has rotated personnel at the space station.

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

The three astronauts waved their hands at the camera after leaving the cabin and greeted them.

They were rushed to the Spark Technology Medical Laboratory by flying cars.

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

They have lived in the space station for more than half a year, which 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 the three astronauts looking a little nervous. He knew that anyone would feel nervous when he was watched by many doctors in white coats and undergo various unknown examinations.

He quickly comforted: "Don't worry, it's not because your body has lesions because of life in space, and life in space stations will not leave you with root causes.

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

Finding the rules of cell changes can effectively target and make more comfortable arrangements for the future life of astronauts."

Du Long gritted his teeth and said, "Please rest assured, my mental awareness is very high, even if it is not a problem to donate organs, you should carefully check my physical condition."

Song Ning, director of the astronaut training base, listened to Du Long's words, and explained in a gentle tone: "You really don't need to worry. This is just a routine inspection. Every astronaut must perform this inspection procedure after returning.

If there is really a problem with your body, we will notify you as it is true.

A thorough examination can also effectively prevent the body from being delayed by the disease. If you really don’t suffer from certain diseases, it’s not a happy thing for everyone.”

Authoritative doctors and biological scientists began to conduct detailed examinations of the bodies of the three astronauts, from the state of genes to the state of cells, from the function of organs to the coordination of the human system, without any mistakes.

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

Chen Jin was responsible for reading to them this report, which was carefully examined and jointly prepared by hundreds of authoritative experts.

"The three astronauts' bodies are medically healthy, and they do not suffer from any disease."

After hearing this, Song Ming relaxed his expression. He was actually very nervous, afraid that the astronauts would suffer from irreparable severe illness.

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

While dedicating to the country, you also suffer from certain diseases, which will make the hero very sad.

Astronauts live in space stations for a long time and suffer from certain diseases, which is also a major impact on the aerospace industry.

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

"The three astronauts just hadn't reached the level of illness. They lived in the space station for half a year and their bodies also showed some changes.

The astronaut training base has detailed inspections of astronauts, and we have obtained health information about their lives at the astronaut training base.

Through the comparison between these data and their current physical condition, some problems existing in the astronauts were discovered."

Chen Jin's words raised the worries in everyone's hearts again. They were waiting for Chen Jin's specific conclusion.

"The human body is really fragile. The three astronauts have great bodies. They just lived in the space station for half a year and their bodies have undergone some slight changes.

The red blood cells of the three astronauts have mutated, and the efficiency of red blood cells transporting oxygen is accelerated.

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

The oxygen produced in industrial production must be different from the composition of air.

We just tried our best to adjust the ratio of carbon dioxide and oxygen, and filled it with some nitrogen and water vapor as supplementary ingredients.

The human body has sensed the lack of oxygen from astronauts, and red blood cells have begun to speed up transporting oxygen to various tissues.

This causes some organs of astronauts to become oversaturated, which is manifested in external excitement, but the lifespan of cells that make up their organs is no longer as long as that of normal people.

The genes of the three astronauts were normal and there was no special mutation.

But the three astronauts' cancer cells were produced at a rate of 5 times higher than before. Fortunately, their immune system was not a problem, and the cancer cells they produced were killed by the immune system.

Because the gravity of the space station is low, the bone density of the three astronauts has weakened.

There will be no impact on the body now, but if you live in areas where gravity is not as strong as the Earth for a long time, bone density will continue to decrease.

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

Zhou Yu was not surprised when he heard Chen Jin's introduction and said, "We could have predicted these impacts before, and scientists have made perfect explanations.

This is why the human body has too strong adaptability to the environment, which leads to these problems.

This phenomenon cannot be effectively solved now, but this is only a problem that needs to be solved in the future. 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 in a heavy tone: "You may have expected these things long ago and will not be surprised by them. They only prove that our human body is very fragile and is completely unsuitable for living outside the earth.

Even some extreme environments on the earth cannot bear it.

This time, our experts used the joint detection method of gene cells and found that European and American scientists had not discovered or published problems before.

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

The germ cells in their bodies are extremely low in activity and cannot form embryos at all.

Our scientists combined the astronauts' physical analysis to find the specific reason for this problem, which is the stress response of the astronauts' physical body.

In this state, people cannot breed offspring.

But this is a reversible variation, and as long as you live peacefully on the earth for a period of time, you will recover.”

Feng Haiman said indifferently: "This kind of problem is not a problem at all. Astronauts are not allowed to fall in love for work. Who would have a baby in the space station?"

Chen Jin waved his hand and said seriously: "Other problems are small problems, and such problems are big problems.

Could it be that we are just living on space stations, landing on the moon, landing on Mars, or taking spacecraft 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 clones to develop the universe, and this kind of thing should be discovered and resolved early.”
