Shenzhou 14 manned spacecraft landed safely at on the evening of the 4th, which also marks our China's aerospace industry. Another phased victory was achieved.
Recalling the landing scene at night, I believe everyone still remembers it fresh. When did Indian netizens see the safe landing of our country?
Many people only see the glamorous side of the astronauts, but they don’t know the efforts they have made behind their backs. The efforts they have spent 180 days in space are unimaginable to ordinary people.
Because many people know very little about this knowledge, in fact, this success is inseparable from the joint efforts of our scientific researchers and astronaut , and also represents the brilliant achievements of our country's aerospace industry.
They have already put in more efforts than ordinary people since the selection. We all know that to successfully be a simple astronaut is not just a simple word, but also a move for your ideals.
This time, Deng Mingqing of Shenzhou 15 was the first batch of astronauts to prepare for war in my country. He was the same group as Yang Liwei and . Due to various reasons, he missed the dream of Feitian.
For him, this time Shenzhou No. 15 was an excellent opportunity for him. It was precisely because he had never given up his dream that he succeeded this time.
We all know that Deng Mingqing is 56 years old this year. If there is no chance to go to heaven, the chances will become fewer and fewer in the future. He waited for 25 years at this moment. I have never given up my previous dream.
Silently as my original dream, I have been working hard and striving. This may be the spirit of China's aerospace . It is always ready. If the motherland needs it, it will rush to the front immediately.
State of Shenzhou 14 was successfully implemented. It also marks that Shenzhou 14 has successfully completed its mission, and the whole country is celebrating rare joy. It once again witnessed the great victory of our country in aerospace.
But do you know? As astronauts, it is not easy for them to live in space. In ordinary things that are simple, they will become difficult in space.
Shenzhou 14 in space for 180 days How did they spend it?
First of all, the biggest problem they face is the impact of weightlessness on them. People who live on earth cannot understand what impact weightlessness can have on a person.
In a weightless environment, the flow direction of the human body's blood will change. We all know that the reason why the blood in our whole body can circulate is not only related to the gravity of the earth, but also has a lot to do with the pressure of the heart.
The heart promotes blood circulation throughout the body through its squeezing ability. We compare the heart to a water pump, which is a power system that uses its own power to transport water to the heights it needs.
And in a weightless environment, the power of the heart. It will weaken, and the blood in the human body is in a state of weightlessness. At this time, the blood will flow upward and gather in the upper part of the body.
At this time, the feeling is that you are headache, heat, swelling, and feeling burst inside. This feeling is equivalent to practicing handstands on the earth for a long time, which gives you the same feeling.
These are the first points they need to overcome. To overcome this, it has a lot to do with their training. When training astronauts, there will be special equipment to simulate practicing in a weightless environment.
There is an emergency stop button in each device. If you feel physical discomfort during training. Or other factors, you can press the emergency stop button. Let this training stop.
But in all the astronaut training in my country, no one pressed this button. They are all persisting and working hard. Use your persistence to exchange for your own physical endurance.
This is about the impact of weightlessness on their bodies.
In addition to these, it is a question that many people are concerned about. How do they go to the toilet? In a weightless environment, it is very difficult for them to go to the toilet.
First of all, the toilets they use are different from those on the earth. Their toilets are all customized, with the purpose of satisfying use in weightless environments.
Toilets on the earth are all flush toilets. In space, water is a very valuable resource so that they will not be wasted easily. The toilets they use are specially made toilets with suction.
When urinating and defecating, they will first fix themselves on the toilet, and then rely on the suction force to directly discharge human excrement into a fixed container.
This fixed method can easily separate urine. After special treatment, the isolated urine becomes the key to oxygen production. It seems that this process is very simple, but in fact it is quite difficult to use.
Their diet in space is all about fast food in aerospace. After making it on earth, it is packaged in the air and brought to space for consumption. These meals are all nutritious and reasonable.
When eating, just heat it in the microwave. Many people will say that there is no difference on earth. In fact, their difficulty is not the heating of food, but the problem of how to eat.
Because in a weightless environment, the function of human swallowing will degenerate. To put it bluntly, they use the power of the upper palate to forcefully deliver food to their esophagus, and this is repeated this way of eating.
Although these space foods are very nutritious and can be made according to everyone's taste, this way of eating is a very difficult thing. They have to eat it like this several meals a day. The difficulty can be imagined.
Not only do they have to solve life problems, but they still have missions in space. This time, the main mission of Shenzhou 14 is to complete the construction of space station . In a weightless environment, they still have to work.
Careful people will find that when they work, most of them will stand in the place, with something similar to a rope on the ground, and fix their feet on it, so that they can barely gain a foothold.
When facing the interview with the TV station, they also fixed themselves in one place, endured the headaches in the face of the camera, kept smiling, and presented their beautiful side to us.
The electricity used in the space cabin is all solar panels outside the cabin, which is powered by them in circulation and provides a continuous need for lighting for their daily life in the cabin.
The spacecraft is very fast in space. You may not feel the speed in the space cabin. The reason is that there is no good reference. Do you know? The spacecraft orbits the earth for about 90 minutes.
In space one day, you can see 16 sunrises. This will cause some damage to their biological clock and are particularly prone to fatigue. Besides, in a weightless environment, their bones and bones will undergo great changes.
Their height is higher than that on the earth. This is because bones will stretch when they are not subjected to gravity. After stretching, they give people the feeling that they look taller, which in fact will also cause the bone quality to decline.
But the stretching of the bones will also cause muscle strain. The muscles are not subject to gravity, but have great ductility. Therefore, shoulder pain, waist pain, and leg pain are all things they need to bear.
In space, they also keep exercising every day. Try not to let such things happen. It will also slow down the damage caused to your legs due to weight loss.
or above are the problems that astronauts have to face every day in space.It's really not easy. They are still persisting in this environment. He is determined to make his due contribution to China's aerospace industry.
When the spacecraft returns, they still have to experience some unknown dangers. The most terrifying thing is the black barrier area , which lasts about 5 minutes. During this period, the spacecraft loses contact with the ground. Many dangerous factors may occur at this stage.
Those who have watched the video of Shenzhou 14 return may know more or less about this, so I won’t say much about it.
Now Shenzhou No. 14 has returned to Beijing, and has briefly met his relatives, drank millet porridge, mutton soup, etc. Is this space trip going to end? As astronauts, you can return to your own lives?
Actually, this is not the case. They need to have more important things to do next. What will the astronauts do next after successfully returning?
Human exploration of space is currently only at the superficial stage, so unknown things in space are always in a guarded attitude.
To put it bluntly, what if an unknown virus is brought down in space and spread to humans? The consequences are unimaginable. After the astronauts come back from space, they usually have to go through three periods: isolator, recovery period, and recuperation period.
quarantine period
After returning from space, they may carry unknown microorganisms on the astronauts. Of course, some of these microorganisms will cause certain harm to human health. The isolation period is to prevent the spread of this microorganism.
There is also strong radiation in space, which may cause genetic dysfunction and other conditions. During the quarantine period, this potential risk can only be completely eliminated through medical means.
recovery period
People who have lived in space for a long time will gradually adapt to the living conditions in space. When returning to the ground from Shenzhou 14, we can clearly see that our astronauts are sitting on a stool and someone is carrying them away.
This is because in a weightless environment, the bone density of the human leg has changed, and the legs are no longer enough to withstand the weight of the body. This can only be used to slowly adapt to the life of the earth during the recovery period, starting from learning to walk.
Cultivation period
means that the microorganisms that should be excluded have been eliminated, and there is no problem with gene mutation. At this time, people have basically adapted to life on the earth, but their bodies are still relatively weak, and they have to go through some cultivation at this time.
enhances nutritional supplements. Only after the exercise of various instruments can you go home and officially live on earth after the vital signs are fully restored to normal standards. This stage can range from at least three months to six months. They are really not easy.
to the end
I want to say that no one can succeed at will, and no country can be powerful quickly. Behind this is inseparable from people. It is precisely because of this that our country has such people who dare to make their own efforts for the development of the motherland.
China's aerospace industry will achieve remarkable results. The country, scientific researchers, astronauts, ground commanders, spacecraft manufacturing enterprises, etc., are only these people's hearts tied together. You can create leaps again and again. I once again told all the personnel of Shenzhou No. 14 that you have worked hard.
