Chapter 216: Threading a Needle Through a Thousand Miles, the Focus of the Whole World [Please Subscribe]

As Xu Yuan's fame in the academic world grew, many fans spontaneously set up Penguin groups and forums, but Xu Yuan himself did not have a public personal account on the website platform.

Under such circumstances, he suddenly opened a Weibo account and posted updates, and the official accounts of Qinghua University, Yenching University and others also reposted the updates.

Naturally, it instantly attracted the attention of netizens, who clicked in to follow and leave messages.

In a very short time, it once again topped the hot search list.

"It's actually the living God Xu. I got such a big surprise just after waking up. It looks like today is going to be a lucky day."

"Fuck."

“Thanks to Professor Xu for letting me see the Fields Medal.”

"My family runs a gold shop. I can tell if it's gold by just touching it. Professor Xu, please send it to me."

"Professor Xu, does Qinghua University know that you are so naughty? I wonder how many mathematicians in the country will be envious of you now."

"This is not just something that is admired by mathematicians in China, but also by mathematicians overseas."

"You guys are so fast. I immediately clicked to follow you, but it already has over 100,000 followers."

"There are so many official accounts. I even saw some celebrities leaving comments. This is really impressive."

……

Xu Yuan's first Weibo post quickly went viral, with the number of views rapidly rushing towards one million.

Even the number of fans has exceeded 500,000.

Considering the current number of Weibo users, which exceeds tens of millions, this data can be considered astonishing.

A number of official media accounts of various universities and institutions left messages in the key comment area, welcoming Xu Yuan to open a Weibo account. The official Weibo account also commented immediately to congratulate Xu Yuan on winning the Fields Medal.

In his personal introduction, Xu Yuan only listed his two identities in the field of mathematics: professor at the School of Mathematics of Qinghua University and editorial board member of the Journal of Mathematics.

After taking a quick look at everyone's messages, he put away his phone and stopped paying too much attention.

Although many netizens hope that he will post on Weibo more often, this is obviously impossible.

Just go online occasionally to give everyone a surprise.

With the successful conclusion of the International Congress of Mathematicians, the Tiangong-1 space laboratory module was successfully launched from the Suzhou Satellite Launch Center.

It was launched with zero window precision and successfully entered the predetermined orbit.

Because Tiangong-1 is a project of the Shanghai Academy of Space Technology, with Academician He Luping in charge, they have a lot of experience in launching into orbit and no problems will arise.

On the day of the launch, Xu Yuan was not at the flight control center, but was discussing the mass production of composite materials with Academician Zhang Jin.

After all, even if the technology is mastered, it cannot be applied to drone fuselages if enough materials cannot be produced.

Fortunately, Zhang Jin has been studying carbon fiber composite materials for so long that he has relatively mature plans in all aspects.

Eventually, the state took the lead in restructuring the carbon fiber material manufacturing company and replacing the original equipment.

Using completely new technologies to produce high-performance carbon fiber composites.

And it will be supplied first to Jincheng Aircraft Design Institute.

Once the production scale is increased, it can be widely used in aerospace, military industry and other fields.

Even after it becomes stable, it can be developed into the civilian field.

The successful launch of Tiangong-1 immediately shifted the focus of overseas media from mathematics.

There has been a lot of coverage of this news.

But everyone understands that the successful launch of Tiangong-1 does not mean anything.

It mainly depends on whether the manned spacecraft launched later can complete rendezvous and docking with Tiangong-1.

But there is no doubt that many media and scholars in the aerospace field are pessimistic about this experiment.

The main point is that as it is the first orbital rendezvous and docking, without experience, the probability of success is very low, unless the goddess of luck blesses you.

Some people even said that they could have anticipated the failure of this connection.

It is said that this will be a very serious spacecraft collision accident in the aerospace field.

Compared with the pessimism about the Tiangong-1 docking test, the International Space Station is in high spirits.

The construction of the International Space Station has been completed this year. After discussion among all members of the International Space Station, it was finally decided to hold the Space Agency Summit in Neon East View in early September.

-

Wednesday, April 2010, 9.

East view.

In the morning, a meeting of heads of space agencies attended by several members of the International Space Station officially began.

NASA director John Bolsons, who was sitting in the middle of the stage, spoke first.

Describe the current situation of the International Space Station.

In the audience were journalists from all over the world.

"I am honored to tell you that the International Space Station has been completely built and put into use."

"Next, we will work with our space station partners to develop applications for the International Space Station, which means that researchers will have more opportunities to conduct experiments in the microgravity environment on the station."

"In addition, the space station crew has agreed to find ways to reduce the annual costs of operating the International Space Station."

"And the service life of the International Space Station will be extended. We will ensure that the components on orbit can function until 2028 at the maximum."

As Bolsons talked about the situation of the International Space Station, many reporters from member forces in the audience were also very excited.

In their view, the International Space Station is undoubtedly a great project built by human civilization.

It means that humans already have the initial possibility of conquering space.

As a member, I naturally feel proud.

Soon, a reporter signaled that he wanted to ask questions and interview.

Looking at the excitement expressed by everyone in front of him, Bolsons felt extremely happy and satisfied in his heart.

He immediately chose one of the female reporters with wavy blonde hair to ask a question.

"Hello, Mr. Bolsons, I am a reporter from the Times, and it is an honor to ask you questions."

The female reporter who was called immediately greeted him, not hiding her excitement while speaking.

"Excuse me."

Hearing this, Bolsons raised his hand to signal the other party to ask a question.

Seeing this, the female reporter did not hesitate and immediately asked the questions she had prepared in her mind.

"Mr. Bolsons, what are the management and policies of the International Space Station?"

"Our International Space Station is large enough to support full operations with a six-person crew on board for extended periods of time."

"The International Space Station is a resource that supports on-orbit research and exploration, as well as driving the advancement of advanced science and technology. These important roles have been unanimously recognized by the members involved in the construction."

"Currently, members of the space station construction cooperation have reached a preliminary consensus on the future development and application of the space station." Bolsons said these words in a relatively official manner in response to reporters' questions.

As for other member representatives such as Oukong Bureau sitting nearby, they also expressed their opinions in the following period of time.

Answered more questions from reporters from different regions.

As time passed, the atmosphere at the scene gradually became more and more frenetic.

We are proud of possessing the most advanced aerospace technology.

However, since it is the critical moment when Tiangong-1 and the manned spacecraft will conduct docking tests next month, it will inevitably be mentioned in this kind of occasion.

After all, one of them is the world's first international space station, which has been fully built and put into use.

It was built by multiple member forces and can be regarded as a great project of human civilization.

The other is to build the world's second space station on its own.

And the track docking technology has not yet been mastered.

Any journalist can see the great international significance of this news.

So finally a reporter from Reuters was the first to raise this question to the head of the Ouang Air Force Administration.

"Mr. Walter, the Chinese side just successfully launched their first space laboratory module at the end of last month, and they plan to launch a manned spacecraft next month to conduct a spacecraft orbital docking test mission."

"Do you think their experiment will be successful this time? Do they have a chance to build a second space station on their own?"

Wallner, who was sitting next to Bolsons, did not answer the question immediately after hearing this. Instead, he turned his head and looked at Bolsons and smiled.

Obviously, I am not surprised at all that this issue came up in today's meeting.

After a two-second pause, he smiled and answered.

"I believe that no member involved in the construction of the International Space Station would say that they would build a space station alone, because everyone knows that this is impossible to do."

"As for their first orbital docking test, I can only wish them success."

"Mr. Walter, do you mean that you are not optimistic about this experiment?" the reporter continued to ask.

Before Wallner could answer this time, Borsons next to him suddenly said, "The exploration and research of aerospace technology is bound to fail and cause accidents. It doesn't matter even if we fail this time." Anyone with a discerning eye could easily understand the implication of his words.

If I had to use a word to describe it, sarcastic would be particularly appropriate.

And Bolsons' answer went far beyond that. He announced something new right after he finished speaking.

"There is one more thing at today's meeting. We will release the international docking system standards."

“This international standard will provide common interface guidelines for future spacecraft docking.”

“Applicable spacecraft range from manned and autonomous vehicles for low-Earth orbit missions to deep space exploration missions.”

"Of course, this system standard only serves the members participating in the construction of the International Space Station. Other forces cannot enjoy this convenience."

Establishing system standards for orbital docking of space vehicles will undoubtedly make orbital docking simpler.

It just so happened that at this time, Tiangong-1 was still conducting orbital docking tests to master this technology.

This move is to show off the country's advanced aerospace technology.

The new news announced by Bolsons was naturally well received by the reporters on the scene.

Thinking that there is new content in today's report.

But there are exceptions to everything. There was a man with a yellow skin face in the crowd, and his expression looked very gloomy at the moment.

His hands under the table were clenched into fists and were shaking uncontrollably.

This is the body's reaction when one is extremely angry.

As a reporter of CCTV stationed in Neon, Dong Jun naturally had to attend such important meetings in the aerospace field.

Originally, he was looking forward to this conference. After all, knowing the status of the International Space Station would also be beneficial to the construction of the domestic space station.

During the question-and-answer session just now, he raised his hand every time, hoping to get the right to ask questions.

All of them were simply ignored.

Although he felt a little regretful, he didn't say much.

But after hearing the questions from the Reuters reporter and the answers from Bolsons and Wallner, he was immediately filled with indignation and could hardly control his anger.

China’s Tiangong-1 has just been successfully launched, and is about to launch a manned spacecraft for the first docking test.

This represents whether China can master orbital docking technology and lay the foundation for building the world's second space station.

It can be said that the country is full of confidence in this regard.

Looking forward to this day very much.

Now the manned spacecraft has not been launched yet, and the two spacecraft have not been in orbit, but Woerner and Borsons are still criticizing it.

They even deliberately brought out the international docking system standards, which was obviously aimed at those who did not participate in the construction of the International Space Station.

In this situation, if you don't speak up to express your attitude, it would be a loss of professionalism.

The thought stayed here, and he immediately made a decision.

Without permission to ask questions, he stood up from his seat and questioned Bolsons.

"Hello, Mr. Bolsons, I think what you said is totally unreasonable."

"We have already achieved manned space flight and successfully launched the first lunar exploration satellite. We are not slow in the development of space technology, so I believe that this spacecraft orbital docking test will be a complete success."

As Dong Jun finished his powerful English speech, he instantly attracted the attention of everyone present.

Obviously no one expected anyone to do this.

When faced with Dong Jun's approach, other reporters expressed contempt but mostly admiration.

After all, from Dong Jun's perspective, this behavior is worthy of admiration.

Bolsons maintained his original expression, as if he didn't take this episode seriously at all.

While the security personnel on the scene asked Dong Jun to leave, he continued to expose the news to other reporters in the audience.

"At the end of this year, our Space Exploration Technologies Corporation will also launch the Dragon spacecraft and recover it."

“This will successfully mark the first time a commercial company has successfully recovered a spacecraft reentering from low Earth orbit.”

What he meant was very simple. Our commercial companies already have the technology to recover spacecraft. How can you claim to be leading in space technology?

It can only be said that although Dong Jun demonstrated his professionalism, it did not have any impact on the meeting.

After the meeting, major media outlets also reported on the content and events of the meeting.

The Times reports that the life of the International Space Station will be extended and it will operate until 2028.

Reuters directly stated that the Ouang Space Administration was not optimistic about the docking of Tiangong-1.

Coupled with the release of the international docking system standards, it quickly became a hot topic in international news.

For domestic netizens, the successful construction of the International Space Station is indeed something worth celebrating from a purely human perspective.

It symbolizes that human civilization has taken another step towards space.

But after seeing the comments made by the two aerospace leaders, Borsons and Woerner, regarding the Tiangong-1 space orbit docking mission, he suddenly became very angry.

You should know that the China Construction Bank failed to successfully join the International Space Station because its application was rejected by the other party.

In desperation, he had to build the world's second space station by himself.

The docking test hasn't even been carried out yet, but it's already been criticized so badly. Even the best tempered person can't help but explode.

However, the reporter Dong Jun's actions won great support and admiration from netizens.

Last month, the domestic mathematics community just won the Fields Medal, successfully breaking the previous record of winning awards in the international mathematics field.

It can be said that it has greatly enhanced people’s self-confidence and pride.

Under such circumstances, we are naturally full of firm confidence in the docking test of Tiangong-1.

I believe that both this orbital docking and building our own space station will be successful.

This view has not been shaken by overseas opinions.

What's more, Xu Yuan, who is regarded as an idol by netizens, is also a researcher at the Space Technology Research Institute.

Being responsible for space orbit docking technology also makes people feel more at ease.

Some people even left messages on Xu Yuan's Weibo, hoping that Xu Yuan could reveal some information about the docking mission.

In short, everyone is very excited and is looking forward to the National Day holiday even more.

We want to see the successful docking of Tiangong-1 into space orbit and use facts to prove our own aerospace technology.

At the same time, he gave a strong counterattack to the contempt of Bolsons and Wallner.

"Their aerospace technology is indeed advanced, but don't you see how many years they have been developing in the field? Although we started late, our progress is amazingly fast."

"They refused to allow us to participate in the construction of the International Space Station, and now they are confident that we will fail. In the words of the Prime Minister, I have never seen such a shameless person."

"I believe that the Space Technology Research Institute will be able to handle it. After all, Xu Shen is also involved in this mission."

“This reporter is really great.”

"As the reporter said, when we were carrying out the Chang'e-1 lunar exploration satellite project, we were also launching a lunar exploration satellite for the first time, and it was also a complete success."

"I really want to fast forward to the day when our space station is completed."

"I am now waiting for the manned spacecraft to launch and dock. I want to see how interesting the expressions of these two people will be when the time comes."

"Does Professor Xu have any inside information? Can you give us some reassurance first?"

……

"You must have read the news online these two days. Now we have become the focus of the world's attention."

In the office of the Space Technology Research Institute, Chen Jianfang sat on a chair, pointing at the discussion among netizens on the computer screen and spoke to Xu Yuan beside him, but he had a faint smile on his face without any nervousness.

"I saw some." Xu Yuan nodded and answered truthfully.

Because the 1st of next month is the launch day of the Shenzhou manned spacecraft, which will enter the planned orbit.

After gradually raising its orbit, it officially docked with Tiangong-1 in space orbit two days later.

Complete the rigid connection to form a combination.

As the actual launch and docking was getting closer, he naturally came to the Space Technology Research Institute more often.

Multiple simulation verifications are required to ensure that no mistakes occur.

As for the International Space Station Member Summit, he naturally paid some attention to the various news and discussions it brought about.

Especially after opening Weibo, I saw many messages from netizens who wanted to know news from him.

However, at this time, some information about the docking can indeed be released through the official account.

Let everyone have more confidence.

But unless you actually see the news of the successful docking, you can't avoid the worry in your heart.

Anyway, there is only about half a month left, and the final result will be very clear by then, so there is no need to worry about this little time.

At this time, Gao Duo, who was sitting on the sofa, listened to the conversation between Chen Jianfang and Xu Yuan.

He turned his head and smiled, "These guys overseas can never get rid of their arrogant and conceited habits."

"They think that by preventing us from participating in the construction of the International Space Station, they can limit the development of our aerospace technology. In fact, it will only make us develop faster and have a space station that is completely our own." Chen Jianfang obviously agreed with Gao Duo's words and immediately took over the conversation and echoed him.

The voice just fell.

He immediately turned his gaze to Xu Yuan.

With the help of the two models built by Xu Yuan, they have simulated the space orbit docking many times. The final results are all complete success, with a 100% accuracy rate.

Based on this data, we are confident about the Tiangong-1 space orbit docking mission.

Naturally, there is no worry.

"Xiao Xu, what do you think of this International Space Station crew meeting?"

When Xu Yuan heard the question raised by Chen Jianfang, he paused for two seconds to organize his words, and then directly expressed his opinion.

"I don't think we need to pay attention to those discussions. The service life of the International Space Station is limited, and it is very difficult to reach its maximum expected lifespan. More operating costs need to be invested."

“I believe that by the time our space station is built, the International Space Station will be almost unusable.”

"By then, I think there will definitely be other forces that will actively seek to establish cooperation with us in the aerospace industry."

There is nothing wrong with what he said, as the International Space Station has just been completed.

Other members can also participate in some scientific research projects.

But once their own space station is built, there shouldn’t be much time left before the International Space Station ends its lifespan.

By then, there will be only one space station left in the world.

In this case, if other forces want to conduct space scientific research experiments, the only way left is to cooperate with them.

It can be considered a reversal of the offensive and defensive identities.

Chen Jianfang understood what Xu Yuan meant and was very excited when he heard it.

As a veteran in the aerospace field, I have no idea how many difficulties I have faced in the development of aerospace technology.

Especially the helplessness in the International Space Station project.

How can I not be happy when I think that this situation will be completely reversed in the future.

"Okay."

“I don’t know how many aerospace professionals are looking forward to this day.”

"I believe this day will not be far away." Gao Duo, who was sitting on the sofa, was also equally excited.

In the following time, they discussed in detail the launch of the manned spacecraft.

At present, the Shenzhou spacecraft and rocket have been transported to the launch center and will be assembled at the vertical lifting center there.

It was then sent to the launch pad in the early morning of the 1st.

Waiting for launch.

In the next half month, Xu Yuan went to the Space Technology Research Institute several times.

In addition to determining the specific launch and docking plan, we also conduct rehearsals for emergencies that may arise during the docking process and try to find ways to remedy them and minimize the losses.

As time passed, it was finally time for the spacecraft to launch.

-

Thursday, November 2010, 9.

8pm.

Yanjing Flight Control Command Center.

There are more than nine hours left before the Shenzhou spacecraft launch.

Although it is the seven-day holiday, Xu Yuan and a group of personnel from the Space Technology Research Institute and the Magic City Aerospace Technology Research Institute are sitting in the flight control command center hall, waiting and paying close attention to the spacecraft launch and space orbit docking test mission.

That is to say, in the next half month, he will basically stay in this command hall most of the time.

Until the docking mission was a complete success.

"After the successful launch of Tiangong-4, it completed the on-orbit platform test and orbit change phase adjustment after two orbit changes in the 13th and 343th orbits. Currently, Tiangong- is operating in a near-circular orbit at an altitude of about kilometers."

"Waiting for rendezvous and docking with the Shenzhou 8 spacecraft."

In the command hall of the Flight Control Center, Academician He Luping, chief designer of the Tiangong-1 project, and Xu Yuan introduced the current situation of Tiangong-1.

It is just a space orbit docking, and Tiangong-1 is the target spacecraft.

The Shenzhou spacecraft serves as a tracking vehicle.

Xu Yuan was naturally aware of all these situations, and nodded immediately to show that he understood.

Chen Jianfang next to him was also not idle. He followed suit and talked about the measurement, control and communication network for this rendezvous and docking.

"The communication network for this rendezvous and docking is composed of two relay satellites, 2 land-based tracking and control stations at home and abroad, three survey ships, and the Yanjing Flight Control Center and Xijing Tracking and Control Center."

“It is ensured that the instructions can be accurately delivered to the spacecraft so that it can complete the rendezvous and docking according to the calculated orbital plan.”

As for the Space Technology Research Institute and the Magic City Aerospace Technology Research Institute, there is no need to worry about the strength of either side.

After all, so many space missions have been carried out, and there will definitely be no mistakes in the necessary procedures.

At this point, Xu Yuan didn't have anything to keep an eye on.

All we can do is wait patiently for the launch time to come.

To ensure that the rocket can accurately send the Shenzhou spacecraft into orbit, it is necessary to achieve a zero-window launch.

The positive and negative error cannot exceed 1 second.

Therefore, whether the launch is advanced or delayed, it will cause errors in the original orbit calculation plan.

Just like that, while everyone in the control center hall was on high alert, people at home were also paying attention to this historic moment.

The CCTV broadcast the launch and docking mission in real time.

This allows everyone to watch the entire process of this space orbital docking test mission on TV.

Since it happened to be the seven-day holiday, many people cancelled their holiday activities because of this incident.

Decided to just stay home and watch the whole thing.

Although the launch was still several hours away, many people had already decided to stay up all night, taking advantage of this time to discuss the event excitedly on Weibo.

"I don't have to go to work tomorrow. I can stay at home and watch the rocket launch and the orbital docking of Tiangong-1. It's so cool."

"From the news it seems like the launch is only around 5am. What if I get up too late and miss it?"

"What? You're still sleeping. Shouldn't we stay up all night?"

"The rocket launch doesn't seem to be anything to look at. The key is the autonomous rendezvous and docking two days later."

"Anyway, we have seven days off, so we must watch the whole thing."

"I had planned to take my son to the zoo tomorrow, but I decided to ask him to watch the rocket launch with me. Guys, am I doing the right thing?"

"What you did is absolutely right, buddy. You can visit the zoo anytime. If we miss the first orbital docking, we will lose it."

"Just think of it as cultivating children's interest in aerospace in advance. Maybe they can work in the aerospace system in the future."

……

At this time, in a room in a residential area, Liu Ping was holding his laptop and chatting with netizens on a forum.

Discuss the launch of the Shenzhou spacecraft and the docking of Tiangong-1.

As an extreme aerospace enthusiast, he usually pays special attention to the developments in the aerospace field.

He will be the first to know any new information released and share it with his friends in the group.

Even when the China Aerospace Science and Technology Corporation announced the launch mission of Tiangong-1, he was the first to discover and spread it in the group.

If you observe his bedroom and workstation, you will find models of rockets and the Chang'e-1 lunar satellite. He can definitely be called a serious space enthusiast.

Ever since he learned about the launch of Tiangong that day, he has been looking forward to this day.

Originally, when he got off work this afternoon, a female colleague wanted to ask him out to see a movie and have dinner tomorrow.

Even explicitly stated that they wanted to invite him.

But he didn't even think about it and just refused.

After all, he had planned long ago to watch the special live broadcast of the launch and docking all night long.

How could you easily change your plan just because of someone else's words?

Just when he was chatting enthusiastically with his friends, the advertisement screen on TV suddenly disappeared, and was replaced by two familiar hosts, a man and a woman.

Apparently this special live show has begun.

"Welcome everyone to watch this special live broadcast of Wanli Threading the Needle."

……

"Threading a needle through thousands of miles?"

Liu Ping was stunned when he heard what the host said.

But he reacted in a flash.

Carry out such a long-distance precise orbital docking mission in orbit at the same altitude.

It's just like threading a needle through thousands of miles.

Thinking of this, he put his notebook aside and focused all his attention on the TV.

The same situation also occurs among other people in major cities.

Everyone is looking forward to the successful completion of this mission.

Because the central station launched a special live broadcast program, Chen Yuran chose to stay and work overtime instead of going home.

She also thought that after the launch was successful, she would follow others to the flight control center for an interview, and she would be able to meet Xu Yuan at that time.

As for the option of mission failure, it never appeared in her mind at all.

no way.

She has absolute trust in the person she loves.

Time passed minute by minute, and soon several hours passed. At 5 a.m., the rocket officially stood on the launch pad in the picture.

The Shenzhou spacecraft is on top of the rocket.

In the command hall of Yanjing Flight Control Center, Xu Yuan, Chen Jianfang, He Luping, Gao Duo and others.

Attention is also focused on the huge screen in front.

The countdown that has emerged is particularly eye-catching.

Fifty-eight minutes left until launch.

"All tests on the rocket's electrical performance and other aspects have been completed, and the propellant has been filled."

"Rocket trajectory correction successful."

Xu Yuan sat in his seat, listening to the various announcements in the hall, his expression becoming increasingly calm.

On the other hand, Chen Jianfang, Gao Duo and even He Luping seemed more and more nervous as the launch time approached.

Although they are all veterans in the aerospace system and have participated in many rocket and satellite launch missions, they should not be so nervous.

But after all, this was the first orbital docking test mission, and there was no experience to compare with before. Even with Xu Yuan's two models as a guarantee, it was inevitable that he could not be completely calm.

Xu Yuan also expressed his understanding of their situation, as this mission has become the focus of attention of the whole world.

The pressure on my shoulders is indeed enormous.

However, Xu Yuan had only one requirement, which was to ensure a zero-window launch so that the rocket could enter orbit accurately.

Based entirely on its own orbital calculations, the orbital docking test mission was successfully completed.

Obviously everyone had stayed up all night and it was almost six o'clock, but they were still excited.

The mind is highly concentrated without any slackness.

In addition to the fact that this day is a day that everyone has been looking forward to for a long time, the more important point is that the time for the rocket launch is approaching.

When the time reached 5:57:40:30, there were only seconds left before the rocket launch.

In a blink of an eye, the commander began to broadcast the last ten seconds.

ten.

Nine.

……

three.

One.

ignition!

As the word "ignition" sounded, a huge tail flame suddenly spurted out from the bottom of the rocket on the screen, pushing the rocket into space.

It was like a sharp sword piercing the sky before dawn.

At the same time, various tracking instructions for the rocket were issued in the hall, and the results were all normal without any problems.

It was not until the Shenzhou spacecraft and the rocket separated successfully that warm applause broke out in the hall.

"The rocket successfully achieved a zero-window launch and accurately entered the predetermined orbit."

Gao Duo looked at Xu Yuan with a cheerful smile on his face at this time, and felt a sense of relief after saying this.

Although this is just the beginning, it is at least a good start.

It helps to mobilize everyone's enthusiasm.

Xu Yuan remained focused. When he heard Gao Duo's words, he nodded and responded in a deep voice.

"It is true that the Shenzhou spacecraft has successfully entered orbit, but in the next two days, the spacecraft needs to complete five phase adjustment orbit changes under the guidance of the ground measurement, control and communication system."

"Until it moves from the initial orbit to a near-circular orbit of 330 kilometers."

Gao Duo listened to everything Xu Yuan said, and naturally understood the importance of these five changes of track.

The time of each orbit change and the orbital height reached are carefully calculated.

The final position after the orbit change is guaranteed, thereby achieving autonomous rendezvous and docking with Tiangong-1.

If an error occurs in the track change, recalculation will be required, which can easily cause docking errors.

This makes it impossible for the two spacecraft to complete rendezvous and docking, and even worse, a collision may occur, causing a space accident.

At this time, netizens were extremely excited. Just seeing the Shenzhou spacecraft successfully launched into orbit gave them a sense of joy that the docking had been completed.

They stopped watching the live special program on TV and picked up their phones and computers to express their feelings to each other.

"It was so cool when the rocket was launched into space. I look forward to the moment when the two spacecraft docked."

"The CCTV compared this docking mission to threading a needle over a thousand miles, which was a good experience of the difficulty and the romance at the same time."

"The docking of two spacecraft over thousands of miles is extremely difficult."

"Let me see how many people have stayed up all night like me."

"I have to go to bed, otherwise I won't be able to be confused when I witness the orbital docking in two days."

“I feel like we’re already halfway there.”

"I have a feeling that this docking will be successful."

"Isn't that nonsense? Being cautious is our old tradition. If we are going to do it, there will be no danger."

……

Xu Yuan didn't have time to use his mobile phone to surf the Internet at this time. When the Shenzhou spacecraft was flying steadily on the predetermined orbit, Xu Yuan stood up, stretched his body and said to Chen Jianfang and others.

"Academician He, and Professor Chen and Professor Gao, why don't you go and take a rest first."

"There's nothing serious going on here right now. Just let me keep an eye on it."

First of all, he is still young in his twenties and will not be too tired even if he stays up all night.

What's more, he slept for a while during the day.

In this situation, He Luping, Chen Jianfang and others must be allowed to rest first.

After all, he is old and if he really has health problems, it will affect the mission.

He Luping, Chen Jianfang and Gao Duo did not try to hold back. After hearing this, they stood up and prepared to go back to their room to rest.

"Thank you for your hard work. Call us immediately if anything happens."

Finally, Chen Jianfang made some more arrangements, then patted Xu Yuan on the shoulder and left with the others.

The ground measurement, control and communication system keeps tracking the spacecraft at all times, and guides it to perform phase adjustment and orbit change when the designated time is reached.

The entire track change process went very smoothly.

And after each orbit change, the orbit of the Shenzhou spacecraft will rise and get closer to Tiangong-1.

Because the lower the orbit, the faster the spacecraft flies, so the whole process is the Shenzhou spacecraft chasing the Tiangong. As some netizens said, threading a needle thousands of miles away can be seen as a very romantic thing.

After an afternoon rest, He Luping, Chen Jianfang, Gao Duo and others also returned to the command hall of the flight control center.

And let Xu Yuan go back to his room to rest.

At this point, Xu Yuan naturally wouldn't be shy about anything.

After saying hello to a few people, he got up and left.

These two days have undoubtedly been a huge drain on everyone's energy, after all, we need to stay focused at all times.

Fortunately, the Shenzhou spacecraft achieved precise orbit changes in the first four phase adjustments, and did not make the mistakes that everyone was worried about.

So they only have the last two crucial steps left to complete the launch mission.

That is, completing the last orbit change, allowing the Shenzhou spacecraft to enter an orbit at the same altitude as Tiangong-1.

It also established an air-to-air communication link with the Tiangong-1 target spacecraft and began autonomous navigation.

Complete approach and pan closer in several stages.

Through the rendezvous and docking measuring equipment, the four processes of capture, buffering, pulling in and locking are completed within fifteen minutes from the start of docking mechanism contact.

Of course, until the final successful locking process, no one in the hall dares to be careless.

Still keeping a close eye on the status of the spacecraft, waiting for the time for the final phase adjustment and orbit change.
