You say you have an iron will, are you serious?

Chapter 357 Forgot that there are three people in the sky

"...I feel a little thirsty after talking about it now~"

"I'm going to drink some water from a very long water pipe. How long is it? Two meters!"

"Let's see, can we drink water?"

Looking at the TV screen, Zhao Mo gave Liu Yang a two-meter-long hose, and then Liu Yang inserted one end of the hose into the Huiyuan juice bottle and started sucking on the other end.

The next moment, the orange-red Huiyuan juice immediately entered Liu Yang's mouth along the two-meter-long hose. She drank the juice and said, "Well, it's so sweet~"

Yang Chan couldn't help but laugh while watching the TV. She found it very interesting and praised: "This space class is interesting. It is interesting and explains things about space. It is impressive~"

Hu Ying, who was holding the little one and feeding him warm water, kept saying "Oops" repeatedly, "I didn't expect that everything floats in outer space, and drinking water is so interesting~"

While the little guy was drinking water, he was babbling non-stop, staring at the TV with his eyes blinking, and beating his hands and feet at the same time, as if he was watching his father.

Zhao Weiguo, who was also watching Space Class, burst out laughing, and then said with emotion: "I never thought we would develop to this point before, it's amazing. In the past few years, we were still farming in the countryside, and Zhao Mo was still farming. He helped us step on the threshing machine, and now he is in heaven, giving lectures in space."

"This is the greatness of China's power!"

Zhao Weiguo said with a look of fascination and regret: "We should not be able to see..."

Yang Chan was speechless as she listened, then automatically blocked the voices of the two of them and finished watching the space class.

"My country is awesome!"

The bickering between the two is almost a normal part of life.

"Imagine the magical world of space and show the powerful power of China!"

"You can see it!"

After reading it, I checked my phone for a while.

Zhao Weiguo laughed out loud when he heard this: "That's great~"

……

Zhao Weiguo glanced at her and muttered: "I can go wherever I go, but I don't know who always gets carsick and can't go here or there~"

Zhao Weiguo was speechless: "I'm too lazy to care about you, you don't enjoy life at all~"

Upon hearing this, Hu Ying immediately replied angrily: "What's the best place to go? With all this time and money, why not eat good food and wear good clothes~"

As expected, this space class triggered a huge response, not only setting off a space craze at home, but also setting off a wave of enthusiasm abroad, yearning for space, curiosity and congratulations on China's aerospace development. The popularity and search frequency of related topics directly became the most popular topic that day.

"Amazing space experiment!"

"Astronauts have worked hard. I hope you will return from your business trip soon. I will wait for you to come home!"

Hu Ying joked on the side: "He traveled to the moon? It would be great to be able to visit all parts of our country."

"Amazing Chinese aerospace industry, amazing Chinese astronauts! That's great! So proud!"

Yang Chan nodded and said with a smile: "This shows that our country's science and technology has made great progress and its comprehensive national strength is increasing. In the future, it will only become more and more powerful. Didn't Zhao Mo say it? It won't be long before we build a Moon base, develop the solar system."

"Magical space, magical space experiments, thank our aerospace heroes for teaching us such a magical lesson!"

Yang Chan didn't wait for him to finish, and immediately interrupted: "It's only ten or twenty years. Dad, you are still very young. Maybe you can travel to the moon by then."

"Ah? Are there three more people in the sky? I forgot all about them! Face covering expression~"

"Today's Internet is so good. It allows ordinary people to see a lot of invisible scenery and broaden their horizons. As a person born in the 1980s, I am grateful to this world!"

……

Ten days is neither long nor short.

If it weren't for Zhao Mo going up to heaven this time, Yang Chan would definitely be like one of the netizens, almost forgetting that we still have three astronauts in the sky who haven't returned yet.

Therefore, Yang Chan didn't think anything of those admiring, praising, and grateful comments, but when she saw the comment about "forgetting there are three people in the sky", she suddenly smiled knowingly, and then secretly calculated the time: "Today is the tenth day. According to the original plan, we have four days to return. It's almost, it's almost~"

However, that night, she saw the "News" report: "...I learned from the Space Command that the manned rendezvous and docking missions of Tiangong-1 and Shenzhou-9 will be completed tomorrow and will return to Earth the day after tomorrow. The plan was made two days in advance..."

"Huh? Two days early?"

Yang Chan was startled at first, and then looked thoughtful: "Why is it so sudden? Did the mission be completed well or did something unexpected happen?"

……

"what is that?"

In space, Zhao Mo, who had finished his lecture, naturally didn't know that they had become the most popular people that day. They were soon attracted by a ball of light rising from the ground.

A satellite was launched from the ground. Soon, the light ball disappeared, and a huge satellite flew past their sight at high speed, with the five-star red flag clearly visible on it. This was a satellite from the motherland!

"Isn't this satellite too big? It's even bigger than Tiangong-1!"

Jing Haipeng said with a surprised look on his face.

"Yeah, I think it's bigger than the 20-ton remote sensing satellite used by the Chang-5 rocket for its first satellite mission~"

Liu Yang was also extremely surprised.

Zhao Mo was also surprised.

Although the satellite disappeared in a blink of an eye, it was so large that anyone who was not blind could see clearly and could tell that it was a very large satellite.

According to the reference object of Tiangong-1, Zhao Mo can probably estimate that the weight of the satellite should be just over thirty tons, and the launch orbit is in a sun-synchronous orbit, which is much higher than the orbit of Tiangong-1 where they are located. many.

Zhao Mo thought for a while and didn't know what this satellite was used for.

"Could it be another remote sensing satellite?"

A thought flashed through Zhao Mo's mind, but he quickly put it behind him and continued to study his "gravity" problem.

Seeing that he didn't speak, Jing Haipeng and Liu Yang thought that he didn't like to talk about this kind of topic, so they looked at each other and stopped talking, and then started busy with their own things.

Another night of sleeping in space~

The next day, Zhao Mo and the others did not conduct any more experiments. Instead, they collectively returned to the Shenzhou-9 return capsule, then closed the passages of Shenzhou-9 and Tiangong-1, and prepared to go home.

Of course, they are not going home today. They still have another task to do, which is the key task of this manned space flight: manual rendezvous and docking.

The chief surgeon task of this rendezvous and docking was handed over to the commanding officer Jing Haipeng.

At 30:140 am, under the operation of Jing Haipeng, the docking mechanisms of Shenzhou 400 and Tiangong were unlocked and separated. After that, Shenzhou began to evacuate and began to keep its distance from Tiangong . Hold the three holding points at meters, meters and meters for a period of time.

Immediately afterwards, Shenzhou-400 flew from the 140-meter holding point to the -meter holding point.

It was only then that Jing Haipeng began to take over the attitude and speed control of the spacecraft, and began to operate Shenzhou 9 to fly slowly towards Tiangong 1, with the targets facing each other for rendezvous and docking.

High-definition camera alignment is used here. The operator mainly looks at the target, and the accuracy is very high.

However, the speed must be slow, otherwise if you accidentally miss the target, it will immediately be a catastrophic accident.

Both Zhao Mo and Liu Yang believed in Jing Haipeng, he would be fine.

In fact, Jing Haipeng's operation can be described as rock-solid.

With the target facing each other, Shenzhou-9 slowly but firmly moved closer to Tiangong-1. After one hour and thirty minutes, the three docking rings on Shenzhou-9 successfully contacted the docking structure of Tiangong-1 and were firmly stuck. Yes, this manual rendezvous and docking task was successfully completed.

"YSE!"

Jing Haipeng shouted happily.

Zhao Mo and Liu Yang, who were lying on their backs, reached out to Jing Haipeng in unison, and the three of them held their hands tightly together, and then laughed happily.

Although this task was uneventful, it was completed smoothly, and we already have automatic rendezvous and docking technology. This manual rendezvous and docking technology seems a bit useless.

However, this is the wisdom of the Chinese people!

Be prepared!

What if the automatic rendezvous and docking fails?

You know, any electronic product, especially automated products, will definitely have problems at some point. No one can guarantee 100% that there will be no problems.

In space, once something goes wrong, it will be a major disaster and there is no way to save it.

At this time, the importance of backup is reflected. If something goes wrong with the original version, the backup can be replaced immediately.

Zhao Mo also knew that to a certain extent, this operation was actually part of systematic control. If any link is not 100% problem-free, then make multiple preparations in this link. In this way, the probability of a problem in a single link is 2%. With a backup, the probability of a problem can be reduced to 1 %, continue to increase the backup, the probability of problems will gradually decrease, and eventually approach 0 infinitely.

Don’t win with specifics, but with systems and as a whole.

At this point, the space mission has been successfully completed and it is time to return.

At 14:42 p.m., under the control of the ground command center, the combination of Tiangong-180 and Shenzhou- yawed degrees in space and entered an inverted evacuation attitude.

Immediately, Shenzhou-9 and Tiangong-1 separated, continued to adjust their attitude after orbiting for a period of time, and then the engines were ignited to enter the return orbit.

After that, during the free taxiing phase, the return module and the propulsion module separated, returned to the atmosphere, and entered the black zone...

Zhao Mo and the other three could do nothing but wait quietly for the landing to be completed.

Zhao Mo didn't pay attention to what Jing Haipeng and Liu Yang were doing. He closed his eyes, his face was calm, and he looked like he was resting with his eyes closed.

In fact, he looked at the Iron Will system in his mind, where the reminder text that the side mission had been completed was glowing, reminding him whether to receive the reward...
