The first thousand and ninety chapters take a cultural class for a day

Also, how these rockets and spacecraft were developed. In space, how do rockets and spaceships fly.

You have to figure out these problems now, otherwise, after you have been flying for nine days, if you encounter some spacecraft failures, you just don’t know what to do.

Therefore, you should study these theoretical knowledge well now. Be sure to learn these theoretical knowledge. Only in this way, after you fly on the rocket for nine days, you will know how to solve the problem when the spacecraft fails.

Otherwise, you don't know what to do at all! So, now you have to learn these theoretical knowledge well.

In a sense, these theoretical knowledge are more important than your physical fitness. Because your physical fitness is just a guarantee that you can live a healthy life in space. It cannot help you solve some machine failures encountered in space.

Therefore, all of us must pay attention. Starting today, we must work hard to learn these theoretical knowledge. Only by mastering these theoretical knowledge can we grow into a qualified astronaut. "

After Zhao Zhongyao finished speaking, he looked at everyone again and said, "Now, please read these study materials first. We will study the content of the first chapter today. If there is anything you don't understand, you can also ask me.

What we learned in the first chapter. In fact, it has a lot to do with our astronauts. Because, what we learn in each chapter is mainly about some knowledge about space.

What is space, in the eyes of ordinary people, nothing is nothing more than blue sky and white clouds. This is just space in the eyes of ordinary people. Space in the eyes of our astronauts is another matter.

We astronauts have to live and work in two hundred kilometers of space. What does two hundred miles of space look like? Up to now, no one has seen it in person. It's just that I know some atmospheric components from some theoretical knowledge.

We all know that the thickness of the earth's atmosphere is between 2000 kilometers and 3000 kilometers. And the activity space of our astronauts is generally in the space of 200 kilometers to 300 kilometers.

In this way, do you feel that we are still quite close to the ground. Does it mean that in the two hundred kilometers of space, it is similar to the surface we live on now. If you think so, you must be wrong.

Everyone knows that the atmosphere on our earth is thousands of kilometers thick. But the thickness of the atmosphere that is truly suitable for human survival is about ten kilometers. Because, within the thickness of ten kilometers, it belongs to the troposphere. The oxygen content in this layer of the atmosphere is very high. Only in this layer of atmosphere can people breathe freely.

But when the altitude of the atmosphere increases to more than 20 kilometers, the oxygen content will be reduced by half. In such an environment, human beings will find it difficult to breathe.

When the altitude of the atmosphere increases to more than 30 kilometers, the oxygen content in the air is already very little. Human beings can no longer survive in such a space. And our astronauts are going to live in two hundred kilometers of space. In such a place, there is no oxygen at all. Humans simply cannot live in such a space.

Let alone oxygen. Even gravity is already very small at this height. When a person reaches this height, he has almost reached the point of weightlessness. In such a space, ordinary people simply cannot live.

What we are studying in this first chapter today is some knowledge about the atmosphere. Don't feel that we seem to have learned this knowledge before. It feels like there is nothing to learn.

If you think so, then you are wrong again. The geography knowledge you learned before. It's just simple knowledge, just to let you understand some of the composition of the atmosphere. There is no further explanation of these space knowledge at all.

But the knowledge we need to learn now is different. What we need to learn is some very detailed space knowledge. Even the knowledge of the atmosphere is very detailed. You must study hard. These theoretical knowledge will be very helpful for your future life in space. "

After Zhao Zhongyao finished speaking, he looked at everyone, wanting to hear their opinions.

These pilots, now listening to Zhao Zhongyao's speech, started talking again.

"Unexpectedly, to be an astronaut, you have to learn about the atmosphere. We have learned this knowledge when we were in college."

"That's right, we are pilots. Didn't we learn this knowledge when we were in the military academy?"

"Yes! We have studied it before. However, I read it just now, and I feel that this knowledge is much more detailed than what we learned when we were in college."

"It seems that we still need to study hard! Otherwise, we will not be able to meet Mr. Zhao's requirements!"

After hearing Zhao Zhongyao's words, these pilots began to discuss in a low voice.

After Zhao Zhongyao waited for them to discuss for a while, he looked at them again and said, "Okay, you have almost read it, let me tell you the main content of this first chapter!"

After Zhao Zhongyao finished speaking, he picked up the chalk on the desk, and wrote space and atmosphere on a blackboard hanging on the wall.

he finished writing

After that, I will give you a lecture.

These ten astronauts, when they saw that Zhao Zhongyao had started to give a lecture, they all listened carefully. After all, there are only ten people sitting in this classroom. If anyone is lazy in this class, the teacher will see clearly.

Zhao Zhongyao took the study materials and told everyone the content of the first chapter.

After listening to it, everyone also felt that the knowledge about the atmosphere that they had learned before was really too simple. The knowledge that Zhao Zhongyao said now has deepened their understanding of the entire earth's atmosphere.

After Zhao Zhongyao spoke, he looked at the pilots again and said, "Okay, I've finished speaking now, do you feel that there are some places that you don't understand! If there is something you don't understand, you can raise your hand to ask questions now. "

After hearing Zhao Zhongyao's words, some of these pilots felt that they didn't understand, so they raised their hands to ask questions. Zhao Zhongyao also helped them explain it seriously. Only then did they understand the knowledge on the learning materials.

This day is over. Zhao Zhongyao just taught them for a day, and the ten astronauts were only students for a day. It felt like I was back in the time when I went to military school.

At night, after Li Chengwei and the others returned to the dormitory, they started talking and laughing again. After all, this first day of life was a bit calm for them. Everything is not as terrible as they imagined. That is, being a student.

"Hey, there is nothing special about the life of these astronaut recruits! Isn't it just to learn some cultural knowledge!" Yang Chengwei said now looking at Zhai Fanggang and Jing Tianpeng.

"In my opinion, Mr. Zhao is too loud and rainy! He won't give us strict training at all, that is, to learn some cultural knowledge!" Zhai Fang just echoed Yang Chengwei's words.

"We don't need to panic. We have been pilots for more than ten years. We have never encountered any kind of dangerous situation in the air. Even if we fly to an altitude of 200 kilometers, it is not the same as dealing with the problems in the work of some spacecraft. What! I feel that we don’t have to worry at all, as long as we can be a good pilot, we can be a good astronaut.”

After hearing what Yang Chengwei and Zhai Fanggang said, Jing Tianpeng also felt that the life of the recruits of this astronaut is really nothing special, and there is nothing to worry about.

But Yang Chengwei was a little worried about what Zhao Zhongyao said during the day. After all, Zhao Zhongyao said it. Their training plan is one, three, five are physical classes, and two, four, and six are cultural classes. Today is Tuesday, so they had a day of culture class first. And tomorrow is Wednesday, and they are going to have physical training.

What will this fitness class look like! These reserve astronauts also have no bottom in their hearts. They don't know what the astronaut's physical fitness class looks like.

"Hey, tell me, what will the physical fitness class of our astronauts look like? Is it similar to the common subjects we trained in the recruit company?" Yang Chengwei thought of tomorrow's physical fitness class, and he just looked at Zhai Fanggang like this Said to Jing Tianpeng.

"What else can it do? It must be similar to the common subjects of our recruit company. Are we now a recruit company? Of course it's not the same as the previous recruit company." Zhai Fang just heard what Yang Chengwei said, so he said again.

"Yes! We don't have to worry at all, but we are just like a company of recruits. What else can there be? It's all the same old way. We don't need to worry." Jing Tianpeng echoed Yang Chengwei's words.

The three of them don't pay much attention to tomorrow's physical fitness class now, feeling that it's just an old routine.

After chatting for a while, the three of them went to bed.

When they first lay down, everyone couldn't sleep. After all, they changed to a new environment and their identities were different from before, which naturally made people feel a little excited.

The beds of Yang Chengwei, Zhai Fanggang and Jing Tianpeng are also next to each other, and they don't feel sleepy now, even though they are lying on the bed, they are still chatting!

"Hey, Cheng Wei! Tell me, will there be a special job on the first night of our recruit company! This first night is supposed to leave some impression on us!"

Zhai Fang just remembered that when he was in the recruit company, but on the first night, their company commander gave them a warning. The first night of the recruit company. In the biting cold wind, they came to an emergency assembly.

Think of that emergency assembly. Zhai Fanggang is still fresh in his memory. Because, the emergency assembly that night was really too dramatic. It just makes people laugh out loud.

Because the soldiers of these recruit companies had just joined the army from the local area. You haven't stayed in the army for a day, how many things can you know! As for this emergency assembly, that was just heard from the squad leader. I have never had such a personal experience. I just heard from the squad leader that this thing is very 'exciting'. It will make you sleep well all night!

Just imagine, a group of soldiers who have just joined the army have never experienced an emergency assembly at all, and then they suddenly came to the army, and in the middle of the night on the first night, they suddenly encountered an emergency assembly. One can imagine what kind of situation that would be.

When Zhai Fang just thought about the situation at that time, he felt very funny! Later, when he went to the military academy and met Yang Chengwei and Jing Tianpeng, he would often tell them about his fun 'first night' when he was in the recruit company.

The situation at that time was like this, when Zhai Fanggang and his recruits of more than a hundred people came from all directions of the motherland

When I arrived at this beautiful military camp, I was very happy.

When I first arrived in the army, the leading cadres were also very enthusiastic towards them, making people feel like they were back at home. It doesn't look like he's here to serve as a soldier.

That night, due to the exhaustion of the day, everyone quickly fell asleep.

It was winter at that time, and the strong wind was blowing outside. Everyone was lying in the warm quilt, feeling very comfortable. Just thinking about sleeping until dawn!

But in the middle of the night, when everyone was sleeping soundly, suddenly there was a rush of whistles downstairs.

"Beep-beep-beep-beep-"

The sound was very ear-piercing, and it woke up all the recruits in the company at once.

For the more than one hundred recruits, this was the first time they heard such a voice. As soon as the sound came, all the recruits woke up.

But everyone didn't know what the whistle meant. After all, we were in the local area before, but we rarely heard such voices. Although this kind of sound can be heard in physical education class at school, the sound is definitely not so harsh.

"What are you doing! Why are you blowing the whistle in the middle of the night to keep people from sleeping?" the voice of a recruit with a southwestern accent.

"What are you going to do? Whoever is full enough to hold on, blow the whistle now." The voice of a recruit from the Central Plains.

"Crazy! Whistle in the middle of the night, and I'm not allowed to sleep." A recruit who was a small gangster in the local area, now heard this sound, and immediately lost his temper.

At that time, Zhai Fanggang heard the voices of these recruits, but he didn't say anything. However, he knew that a storm was coming, and no one could hide from it.
