It is said that they are not afraid of taking risks. For the sake of the aerospace industry of the motherland, they will not hesitate to throw their lives and blood.

But after Zhao Zhongyao listened to what they said, he smiled and said: "This is not something you just want to do. Now, you still have nine astronauts who have not conducted flying experiments! This time, two astronauts are needed. But

I can’t say who can do it and who can’t! For the sake of fairness, I think it’s better to have an assessment competition.”

When Zhao Zhongyao said this, it was natural for the other astronauts to stop arguing. After all, what Zhao Zhongyao said was very fair. In such a competition, whoever has better results will go. This is not

Is the bowl of water level?

Although Zhao Zhongyao also wanted Zhai Fanggang and Jing Tianpeng to conduct this manned spaceflight experiment, he couldn't say so directly! Otherwise, other astronauts would definitely think that Zhao Zhongyao

Looking towards these two guys!

Because of this, Zhao Zhongyao also called Zhai Fanggang and Jing Tianpeng into his office before conducting an assessment on everyone.

Zhao Zhongyao looked at the two of them and said: "Actually, this time, I want you two to conduct this manned space experiment. But I can't let you go directly. Other astronauts are also looking at me.

!I can only give you another assessment. I hope that you two will work harder and rely on your own strength to get a place in this aerospace experiment."

After hearing what Zhao Zhongyao said, Zhai Fanggang and Jing Tianpeng said in unison: "Don't worry! Mr. Zhao, we will definitely be able to defeat them."

"Okay, that's it, you two get ready, tomorrow we will start the astronaut selection assessment." Zhao Zhongyao said again.

"Okay, we get it." The two said together again.

In this way, Zhao Zhongyao conducted another assessment on these nine astronauts. The content of the assessment was similar to that in the previous training team, that is, the theoretical assessment was conducted first, and then the physical assessment was conducted.

The results of the final assessment really satisfied Zhao Zhongyao. Zhai Fanggang and Jing Tianpeng finished first and second respectively, beating the other seven astronauts. They finally got the quota for the next space expedition.

.

Seeing such achievements, Zhao Zhongyao also praised Zhai Fanggang and Jing Tianpeng.

"Well, you two lived up to my expectations for you and got first and second place." Let me praise you first.

Zhai Fanggang and Jing Tianpeng were also very happy after hearing Zhao Zhongyao's words. They both laughed together.

"But, then again, it is naturally not easy to select astronauts. But the training you will face next is also even more difficult.

This time, the mission you have to face is even more important than Yang Chengwei's last mission! Last time, Yang Chengwei just stayed in the space capsule. Until he fell from the sky, he did not get out of the space capsule at all.

.

But this time, it's different. You are going to perform a space walk mission. You want to go into space to feel what kind of environment outer space is like.

So, the training mission you two will accept next is also a training mission, and it is also very hard. I don’t know whether you two are willing to accept it. If you two feel that you don’t want to endure this hardship and are not willing to accept this space mission,

If it is a walking mission, then I can replace it with two more astronauts.”

Before Zhao Zhongyao formally trains Zhai Fanggang and Jing Tianpeng, he also has to say something upfront to make them mentally prepared.

"Mr. Zhao, don't worry! We will definitely be able to complete the training mission. We are all soldiers, how can we be afraid of hardship and fatigue!" Zhai Fanggang looked at Zhao Zhongyao and said.

"Yes! Mr. Zhao, we will never be afraid of hardship or tiredness, we can endure hardship. Just train us." Jing Tianpeng also said the same.

"Okay, then starting from tomorrow, you will start receiving closed training! The training time is half a year. In half a year, we will conduct the second manned space experiment. You two must be mentally prepared first." Zhao Zhong

Haruka said again.

"Yes, everything is subject to General Zhao's command." Zhai Fanggang and Jing Tianpeng were very happy after hearing Zhao Zhongyao's words. They thought that they were about to become real astronauts.

That night, Yang Chengwei also came to the dormitories of Zhai Fanggang and Jing Tianpeng and chatted with them about the next manned space mission.

"Congratulations to you two, you finally have the opportunity to travel to space." Yang Chengwei said as soon as he arrived at Zhai Fanggang and Jing Tianpeng's dormitory.

"Hey, Cheng Wei, what does it feel like to be in the sky? Are you afraid?" Zhai Fanggang looked at Yang Chengwei and asked.

"Yes! Cheng Wei, the last time you went to heaven, I heard that you heard some knocking sounds in the middle of the night. What on earth was going on? How could someone knock on the door in space?"

Of course, Jing Tianpeng also heard about Yang Chengwei hearing some strange knocking sounds in space. He still doesn’t understand what is going on!

Yang Chengwei now pretended to be mysterious and said: "Hey, it's really scary! At that time, I thought it was haunted! I thought, are there ghosts in space? How could it happen in the middle of the night?

The matter of ghosts knocking on the door. To be honest, I am really scared. But fortunately, it is not a big problem. Thinking about it, it is not a serious matter. "

"Hey, what's the reason?" Zhai Fanggang and Jing Tianpeng still don't know what's causing the knocking sound.

After the completion of this space mission, the matter of the knocking sound was of course considered an internal matter and was not made public. After all, this would affect the mood of other astronauts going to space in the future. It is better not to make this matter public.

.

However, Zhai Fanggang and Jing Tianpeng are none other than Yang Chengwei's good friends. Of course, he can talk to these two friends about this matter.

Yang Chengwei now almost knows what is going on. Of course, he is not sure. After all, Zhao Zhongyao said that what he said is just speculation. Before actually seeing those so-called small celestial bodies, no one can

It cannot be proved that the knocking sound that Yang Chengwei heard that night was caused by the impact of these small celestial bodies.

"Mr. Zhao, President Cheng, and I have already studied this issue. Mr. Zhao speculated that it may be caused by small celestial bodies in space. He said that there are also some very small space particles in space. These things are in space

They fly randomly, just like bullets. In fact, their speed is much faster than bullets.

When these small celestial particles collide with the space capsule, they can certainly cause certain harm to the space capsule. However, these small celestial particles are very small, probably about the same size as bullets. Even if such small celestial particles hit the space

On the capsule, it is impossible to cause much damage to the space capsule.

But for the astronauts inside the space capsule, they will definitely be frightened. The knocking sound I heard that night may have been caused by these small celestial bodies hitting the door of the space capsule.

But Mr. Zhao said that all this is just his speculation. Whether this is the case or not, he is not sure. One of your flying missions this time is to find out the cause of the weird knocking sound last time.

What."

Yang Chengwei told Zhai Fanggang and Jing Tianpeng what he heard from Zhao Zhongyao.

After the two of them heard it, they felt that it made sense. It was probably some small celestial particles that hit the door of the space capsule, and then Yang Chengwei inside heard the strange knocking on the door.

However, no one is sure about this now. Only when Zhai Fanggang and Jing Tianpeng fly for nine days can this unsolved mystery be solved.

"Cheng Wei, don't worry! This time after the two of us fly for nine days, we will definitely catch that 'ghost' for you. When the time comes, you have to teach it a lesson." Zhai Fanggang looked at Yang Chengwei again and opened

It was a joke.

"That's right, Cheng Wei. This time, we are flying together for nine days. No matter what happens, there will be someone to take care of you. We will definitely catch the culprit who scared you." Jing Tianpeng

After listening to Zhai Fanggang's words, he also echoed this.

"Haha, okay, I'll leave it to you two." Yang Chengwei also laughed.

Besides, Zhao Zhongyao's current work is also very stressful. On the one hand, he has to conduct intensive training for Zhai Fanggang and Jing Tianpeng. On the other hand, he also has to quickly design a new space suit! After all, the one he designed for Yang Chengwei last time

The space suit cannot meet the needs of this space mission. He must now design a brand new space suit.

The space suit is a personal sealed equipment that protects the life activities and work abilities of astronauts. It can protect the human body from environmental factors such as the vacuum of space, high and low temperatures, solar radiation, and micrometeors. In a vacuum environment, the nitrogen contained in the human blood

It will turn into gas and expand in volume. If a person does not wear a pressurized and airtight space suit, his life will be in danger due to the huge difference in pressure between the inside and outside.

The space suit is a multi-functional garment developed on the basis of the pilot's closed suit. Early space suits could only be used by astronauts in the cockpit of the spacecraft. Later, space suits for extravehicular use were developed. Modern new extravehicular space suits have liquid

The cold cooling structure allows astronauts to carry out activities outside the space capsule.

In addition to the various layers of the astronaut's structure used inside the cabin, the spacesuit used outside the cabin also has three layers: one is the vacuum insulation layer, which is used to protect the astronauts from working outside the cabin or on the surface of the moon and other stars.

It can prevent the heat loss inside the clothing from being overheated and overcooled by the environment outside the cabin. The second is the liquid cooling suit, which is made by changing the gas in the ventilation and heat dissipation layer tube of the space suit inside the cabin into liquid.

Astronauts sometimes work outside the cabin for several hours, and their bodies generate a lot of heat. Gas heat dissipation cannot meet the heat dissipation requirements, but liquid cooling fluid can dissipate the heat very well. The third is the outermost layer, which

In addition to the functions of preventing high heat, anti-wear and protecting the internal layers, it must also have the function of preventing solar radiation and connecting interfaces to other equipment.

For example, it is connected to the umbilical cord during extravehicular activities of astronauts, to the portable life protection environmental equipment, and to the space maneuvering flight mechanism. The helmet of the space suit is composed of a helmet shell, a face window structure, a neck collar and other components.

There are two types of helmets used in manned spaceflight: soft and hard. Hard helmets are divided into fixed and rotating. Soft helmets are mostly used as components of in-cabin space suits. Rotating helmets have a collar on their neck.

There is an airtight movable bearing on the machine, but increasing the number of sealing links will reduce the airtightness and structural reliability, and increase the difficulty of design.

Zhao Zhongyao also knew something about the design characteristics of extravehicular spacesuits during his lifetime. Now, for him, he only needs to design the structure of the spacesuit that he knows.

In this way, in the past six months, while Zhao Zhongyao was conducting intensive training for Zhai Fanggang and Jing Tianpeng, he also began to develop a new generation of space suits for extravehicular use.

Fortunately, everything went smoothly. Half a year later, these two tasks were almost completed.

Of course, other scientific researchers were not idle either. They developed another space capsule and a flight capsule. This space mission was different from the last one. This time, the astronauts did not just stay in the space capsule.

That’s enough, we still need to do out-of-vehicle activities!

The return capsule is obviously not suitable for extravehicular activities. If we want astronauts to conduct extravehicular activities, we must design a completely new flight capsule. Let this flight capsule be connected with the return space capsule.

First use a rocket to launch the space capsule and the flight capsule into space together. Then, let the space capsule and the flight capsule fly in space together. The astronauts can stay in the space capsule first until they need to perform the mission.

, they came out of the space capsule again, and then came to the flight capsule.

Inside the flight capsule, the astronauts have to complete extravehicular activities. After they complete their mission, they return to the ground in the space capsule. And the flight capsule remains in space.

During the past six months, Zhao Zhongyao was also very busy. On the one hand, he had to train Zhai Fanggang and Jing Tianpeng. On the other hand, he had to design and develop a new space suit. He also had to successfully help Cheng Yu and the others to put the first

Space capsules and flight capsules for secondary spaceflight were developed.

Although the return capsule used by Yang Chengwei last time has been recovered, and it still looks good. But manned spaceflight is a high-risk job. There cannot be any problems. It needs to be 100% successful.

matter.

Therefore, even if the space capsule was recovered last time, there is not much problem. But when new space experiments are carried out, the past space capsule will not be used again. It is necessary to develop a new space capsule. Only
Chapter completed!
