On March 5, the Wenchang Space Launch Center in Hainan Province launched another spacecraft.

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

Huaxia media comprehensively tracked and reported on the replacement of astronauts, which was the first time that Huaxia rotated personnel on the space station.

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

The three astronauts just waved at the camera and said hello after exiting the capsule.

They were rushed to the Spark Science and Technology Medical Laboratory by the flying car.

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

They lived on the space station for more than half a year, which was to test the specific changes in human health after living away from the ground for a long time.

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

He hurriedly comforted: "Don't worry, it's not your body that is sick because of your life in space, and life on the space station won't leave you with the root of the disease."

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

Finding the law of cell changes can effectively target and make more comfortable arrangements for the life of astronauts in the future. ”

Du Long had a heroic expression, gritted his teeth and said: "Please rest assured, my ideological consciousness is very high, even if it is organ donation, there is no problem, you carefully check my physical condition."

Song Ning, director of the astronaut training base, listened to Du Long say this, and he 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 he comes back."

If there is a real problem with your body, we will also inform you as it is.

Conducting a thorough examination can also effectively prevent the body from being delayed by the disease, and if you really don't suffer from certain diseases, then not everyone is happy. ”

Authoritative doctors and biological scientists began to conduct a detailed examination 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 human body systems.

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

Chen Jin was responsible for reading the report to them, which was carefully examined and co-written by hundreds of authoritative experts.

"From a medical point of view, the bodies of the three astronauts are in good health, and they are not suffering from any diseases."

After listening to this, Song Ming's expression relaxed, he was actually very nervous, afraid that the astronaut would suffer from irreparable serious illness.

These astronauts were all trained by him, and he watched them work hard for China's aerospace industry.

While dedicating to the country, he also suffers from certain diseases, which makes the hero sad.

Astronauts who live on the space station for a long time really suffer from certain diseases are also a major impact on the aerospace industry.

The booming aerospace industry may be overshadowed by this discovery.

"The three astronauts just didn't get sick in their health, they lived on the space station for half a year, and their bodies also showed certain changes.

The astronaut training base has a detailed examination of the astronauts, and we have obtained their health information about their life in the astronaut training base.

Through the comparison of these materials with their current physical conditions, some problems have been found in the astronauts. ”

Chen Jin's words raised the worries in everyone's hearts again. They waited for Chen Jin's specific conclusions.

"The human body is really fragile, and the three astronauts are in great health, but after living on the space station for half a year, there are some slight changes in the body.

The red blood cells of the three astronauts have been mutated, and the efficiency of the red blood cells in transporting oxygen has increased.

The astronauts are in a vacuum and use the spacesuit to supply oxygen.

Industrially produced oxygen is certainly different from the composition of air.

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

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

As a result, some organs of astronauts begin to be oversaturated with oxygen, which is manifested by their excess, but the lifespan of the cells that make up their organs is not as long as that of normal human cells.

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

However, the cancer cells of the three astronauts were produced at a rate 5 times higher than the original, but fortunately there was no problem with their immune system, and the cancer cells produced were all killed by the immune system.

Because of the low 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 where gravity is not as strong as the Earth for a long time, bone density will continue to decrease.

As a result, the bones are unable to provide effective support to the body, and organs may be damaged, which may lead to fractures after falls. ”

Zhou Yu was not surprised at all when he heard Chen Jin's introduction, and said: "We could have predicted these effects before, and scientists have already made a perfect explanation.

It is the human body's ability to adapt to the environment that causes these problems.

It is not yet possible to effectively solve this phenomenon, 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 in a heavy tone: "You may have expected this, and you won't be surprised by this, it just proves that our human body is fragile and completely unsuitable for living outside the earth.

Even some extreme environments on earth are unbearable for the vast majority of people.

This time, our experts found problems that had not been discovered by European and American scientists or that they had not announced before.

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

The activity of germ cells in their bodies is extremely low and they are not able to form embryos at all.

Our scientists combined the analysis of the astronaut's body to find the specific cause of this problem, which is the astronaut's body stress response.

In this state, man is unable to reproduce.

But this is a reversible mutation that will recover as long as you live smoothly on Earth for a while. ”

Feng Haiman said nonchalantly: "This kind of problem is not a problem at all, astronauts are for work, and falling in love is not allowed, how can anyone give birth to a child in the space station."

Chen Jin waved his hand and said solemnly: "Other problems are small problems, and this kind of problem is a big problem."

Are we just living on a space station, landing on the moon, landing on Mars, or going on an interstellar voyage in a spaceship?

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

We can't always rely on human clones to develop the universe, and this kind of thing should be detected and solved early. ”
