Chapter 1090 First take a day of cultural lessons

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

You have to figure these things out now, or you won't know what to do if you've been flying for nine days and you're running into some ship failures.

So, now you have to study these theories. We must learn and understand these theoretical knowledge. Only in this way, after you fly on a rocket for nine days, will you know how to solve the problem when you encounter a ship's failure.

Otherwise, you don't know what to do! So, you just have to learn this theoretical knowledge now.

In a sense, this theoretical knowledge is more important than your physical fitness. Because your physical fitness only ensures that you can live a healthy life in space. It doesn't help you solve some of the machine failures you encounter in space.

Therefore, we must all pay attention to it, and from today onwards, we must work hard to learn these theoretical knowledge. Only by mastering this theoretical knowledge can we grow into a qualified astronaut. ”

After Zhao Zhongyao finished speaking, he looked at everyone again and said, "Now, you take a look at these learning materials first, and we will study the content of the first chapter today." If there's anything you don't understand, you can ask me.

What we learned in Chapter 1. In fact, it still has a lot to do with our astronauts. Because, the content we learn in each chapter is mainly about some knowledge about space.

What is space, in the eyes of ordinary people, cannot be just a blue sky and white clouds. It's just space in the eyes of the average person. Space in the eyes of our astronauts is a different story.

We astronauts are supposed to live and work in 200 kilometers of space. What exactly is two hundred miles of space like? Until now, none of us have seen it in person. It's just that we know some of the components of the atmosphere from some theoretical knowledge.

We all know that the thickness of the Earth's atmosphere is between 2,000 km and 3,000 km. The space for our astronauts to operate is generally in space of 200 to 300 kilometers.

In this way, do you feel that we are still quite close to the ground? Does it mean that in 200 kilometers of space, it is similar to the surface of the earth where we live now? If you think so, you must be wrong.

As we all know, the atmosphere on our planet is thousands of kilometers thick. But the thickness of the atmosphere that can really be suitable for human survival is about 10 kilometers. Because, within this thickness of ten kilometers, it belongs to the troposphere. The oxygen content in this layer of the atmosphere is very high. It is only in this layer of the atmosphere that people are able to breathe freely.

But when the altitude of the atmosphere rises to more than 20 kilometers, the oxygen content is reduced by half. In such an environment, humans will feel that it is difficult to breathe.

When the altitude of the atmosphere increases to more than 30 kilometers, the oxygen content in the air is already very small. Humans can no longer survive in such a space. And our astronauts have to live in space for 200 kilometers. In such a place, there is simply no oxygen at all. Humans simply cannot live in such a space.

Not to mention oxygen. Even gravity is very small at this altitude. When people reach this height, they have almost reached the point of weightlessness. In such a space, ordinary people simply cannot live.

In today's first chapter, we're learning a little bit about the atmosphere. Don't feel as if we've learned this before. It just feels like there's nothing to learn.

If you think so, then you are wrong again. The geography you learned before. It's just simple knowledge, just to give you an idea of what the atmosphere is made of. There is simply no more explanation of this space knowledge.

But the knowledge we have to learn now is different, and what we have to learn is some very detailed space knowledge. Even the knowledge of this atmosphere is very detailed. You must study hard. This theoretical knowledge will be very helpful for your future life in space. ”

After Zhao Zhongyao finished speaking, he looked at everyone and wanted to hear everyone's opinions.

Now that these pilots have listened to Zhao Zhongyao's speech, they have begun to talk about it again.

"I really can't imagine that being an astronaut has to learn about the atmosphere. Didn't we already learn this knowledge when we were in college before. ”

"That's right, we are pilots, and we learned this knowledge when we were in military school. ”

"Yes, we've studied before. However, I just looked at it, and I feel that this knowledge is much more detailed than when we were in college. ”

"It seems that we still have to study hard! Otherwise, we won't be able to meet Mr. Zhao's requirements!"

After listening to Zhao Zhongyao's words, these pilots began to talk in a whisper.

Zhao Zhongyao waited for them to discuss for a while, then looked at them again and said, "Okay, you've almost seen it, let me tell you about the main content of this first chapter!"

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

After he finished writing, he gave a lecture to everyone.

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 in this classroom. If anyone is lazy in this class, the teacher will see it very clearly.

Zhao Zhongyao took the study material 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. Now Zhao Zhongyao's knowledge has deepened their understanding of the entire earth's atmosphere.

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

When these pilots listened to Zhao Zhongyao's words, some people felt that they didn't understand well, so they also raised their hands to ask questions. Zhao Zhongyao also helped them explain it seriously. Only then did they understand the knowledge in this learning material.

And so it was the end of the day. Zhao Zhongyao also gave them a one-day class, and the ten astronauts were only students for one day. It feels like I'm back in the days of military school.

In the evening, after Li Chengwei and the others returned to the dormitory, they began to talk and laugh again. After all, this first day of life was a bit uneventful for them. Everything is not as terrible as they imagined. It's just a matter of being a student.

"Hey, isn't there anything special about this astronaut recruit's life! Isn't it just to learn some cultural knowledge!" Yang Chengwei now looked at Zhai Fanggang and Jing Tianpeng and said.

"I think that Mr. Zhao is also thundering and raining! Won't we be strictly trained at all, that is, to learn some cultural knowledge!" Zhai Fanggang listened to Yang Chengwei's words, and he also echoed it.

"We don't need to panic. We've been pilots for more than a decade. What kind of air danger has not been encountered. Even if we fly to an altitude of 200 kilometers, is that different from dealing with some problems in spacecraft work? 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 listening to the words of Yang Chengwei and Zhai Fanggang, Sedum also felt that the life of this astronaut's recruit company was really nothing special, and he didn't have to worry about anything at all.

But Yang Chengwei said something Zhao Zhongyao said during the day, and he was a little worried. After all, Zhao Zhongyao said. Their training plan is 135 for physical fitness and 246 for cultural classes. It's Tuesday, so they're going to have a day of culture first. Tomorrow is Wednesday, and they're going to have a physical training session.

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

"Hey, what do you say, what will our astronaut's physical fitness class look like, is it similar to the common subject we trained in the recruit company!" Yang Chengwei thought of tomorrow's physical fitness class, and he looked at Zhai Fanggang and Jing Tianpeng like this and said.

"What else, it's definitely about the same as the common subject of our recruit company. Are we a recruit company now? Of course, it's not much like the previous recruit company. Zhai Fang just listened to Yang Chengwei's words, and said again.

"yes! We don't have to worry about it at all, but it's like a recruit company. What else could there be, it's all the same, we don't have to worry about it. Sedum listened to Yang Chengwei's words, and echoed it.

The three of them don't pay attention to tomorrow's physical fitness class now, and they feel that it is just the same old thing.

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

When I just lay down, everyone couldn't sleep, after all, in a new environment, this identity is different from before, which naturally makes people feel a little excited.

Yang Chengwei, Zhai Fanggang and Jing Tianpeng The beds of the three of them are also next to each other, and they are not sleepy now, although they are lying on the bed, they are still chatting!

"Hey, Cheng Wei! You say, will there be a special job for our recruit company on the first night! This first night is supposed to leave us with some impressions!"

Zhai Fang just thought that when he was in the recruit company, but on the first night, their company commander gave them a dismount. The first night of the recruit company. In the bitter cold wind, an emergency assembly was brought to them.

Thinking of that emergency gathering. Zhai Fanggang still remembers it vividly. Because, the emergency gathering that night, it was really dramatic. It's just a big laugh out of your teeth.

Because, the soldiers of these recruit companies have just enlisted from the local army. You have not been in the army for a day, how many things can you know! As for this emergency gathering, I have just heard from the mouth of the squad leader. I've never had such a personal experience. I just heard from the squad leader that this thing is very 'exciting'. It's going to keep you awake all night!

Just imagine that a group of soldiers who have just enlisted in the army, who have not experienced such a thing as an emergency assembly at all, suddenly came to the troops, and in the middle of the night on the first night, suddenly encountered another emergency assembly. You can imagine what that would be like.

When Zhai Fanggang thinks of the situation at that time, he feels very funny! When he later went to the military academy and met Yang Chengwei and Sedum Tianpeng, he would often tell them about the fun 'first night' he had when he was in the recruit company.

At that time, the situation was like this, when Zhai Fanggang and his more than 100 recruits and soldiers came to this beautiful military camp from all over the motherland, they were very happy.

When they first arrived at the army, the leading cadres were also very enthusiastic about them, and they felt as if they had returned home. It doesn't look like he's here to be a soldier.

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

It was winter, and the wind was blowing outside, and everyone was lying in the warm bed, which felt very comfortable. I just want to sleep until dawn!

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

"Didi-Di--"

The voice was very harsh, and it woke up all the recruits in the company at once.

For these more than 100 recruits, it was the first time to hear such a voice. As soon as the voice came, all the recruits woke up.

But you don't know what the whistle means. After all, we have rarely heard such voices in the local area before. Although I can hear such a voice in physical education class at school, the sound is definitely not so harsh.

"What are you doing! What kind of whistle did the third watch blow in the middle of the night, and let people not sleep. "The voice of a recruit egg with a Southwestern accent.

"me. Whoever is full of food and holds on, now blow the whistle. "The voice of a recruit egg in the Central Plains.

"Nervous! The third watch blew the whistle in the middle of the night, and let me not let Lao Tzu sleep. "A recruit who was a thug in the local area, and now when he heard this voice, he immediately became angry.

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