Two days later, Xu Ziling set off to return to China again.

accompanied by Yang Kaiming, Li Cheng, Duan Zhan, Xia Xueyi, and then the Du family brothers and sisters.

Yang Kaiming and the other big men, of course, are responsible for safety, Xia Xueyi is an assistant, and the Du family brothers and sisters are completely soy sauce.

Originally, I was going to fly directly to the Northern Satellite Launch Center, but considering that there was still time left and there was something going on at the school, I finally decided to stay in Star City for a few days.

The day after returning to China, Xu Ziling went to school, accompanied by Xia Xueyi and the Du family brothers and sisters.

Every September, when the new students enter the school, the car drives to the school gate, Xu Ziling looks at the pair of loaded sentry posts on each side, and welcomes the new students and their parents.

I was filled with emotion.

I entered this door four years ago, and now it's time to graduate in a blink of an eye.

The white horse is really not fake.

Under the leadership of Yang Kaiming and Li Cheng, the scene when I first entered HKUST is still vivid, as if it was just yesterday.

But now, his identity has changed from a student to a teacher.

How could you have thought of this kind of change in the first place?

Slowly entering the gate, Xu Ziling went directly to the Department of Materials, stopped the car in front of the teaching building, and said to Du Hui: "You call your classmate to Mr. Li's office......

"It's good." Whether he could pass the "interview" or not, Du Hui was not sure, nodded, took out his mobile phone and began to contact his classmate.

"Come over in about ten minutes......" The phone quickly hung up, and he looked up and explained to Xu Ziling.

"Well, then you wait here, let's go up first." Xu Ziling could think that Du Hui would definitely be with his classmate, so he didn't ask him if he wanted to go up together, and after finishing speaking, he beckoned several other people to go upstairs.

Li Litian is still the dean, and now it is the time for the new students to start school, of course, there are a lot of things, and when Xu Ziling and a few people arrived at his office, they saw him and a few people talking about something.

Seeing Xu Ziling and them coming in, he just pointed to the sofa next to him and motioned for them to sit first.

A few minutes later, I only heard Li Lao say: "Just follow this plan, you can distribute it quickly." ”

"It's good." A few people nodded in agreement, and then left the office.

"Old Li. (Teacher.) Seeing that they were finally done, Xu Ziling and the others immediately stood up and said hello.

"Sit, sit." Li Litian asked a few people to sit down, and he also sat down on the sofa, smiled and nodded to Xia Xueyi and Du Hui, and asked how a few people felt in Nitan.

After the two answered, they talked to Xu Ziling.

Of course, it's about Du Hui and his students.

"Not bad." Xu Ziling said with a smile, in the past two months, Du Hui's two siblings have often been able to stay up all night until they figure out a problem before resting, just with this kind of learning momentum, he is very satisfied, "Both of them are good seedlings, give a few years, I guarantee that two good experts will be born in the field of materials." ”

"Really?" Li Lao listened to Xu Ziling's words, and immediately became happy, he is an expert in materials, and the field of materials has always been the weakness of the country, and he has a reason to be happy to be able to produce a few young experts.

……

Regarding the graduate student, Xu Ziling had already had preliminary communication with Li Lao before, and a few minutes later, there was a knock on the office door, and Du Hui came in with a girl, and Li Lao was not surprised.

The girl was twenty-three or four years old, with long hair, and her appearance was not very beautiful, she was the kind of durable type, and she came in with Du Hui and greeted a few people very politely.

Xu Ziling has had special training in observation, and if ordinary people say true or false, they still can't escape his eyes, and then Du Hui introduced this girl named Fu Feixia, and he has been observing.

After asking a few questions and making a few jokes, he had a rough evaluation of the girl in his heart.

didn't rush to give an answer, Xu Ziling asked her to go back first and wait for news.

"Originally, I didn't take students, but Du Hui highly recommended you, so I only came here today. Let me explain to you first, if you really want to learn something, not for the graduate degree, then once you become my student, like Du Hui and them, you need to go abroad, and the course will not be too simple, you should think about it yourself...... I'll give you an answer in a week, but when I give my reply, it's when you leave the country, so you think about what I'm saying first, so that you don't want to go when you get it...... Alright, you go back first. ”

I didn't think about replying immediately, after Xu Ziling finished speaking, she asked her to go back and wait for the news, the girl didn't say much, and said goodbye to Xu Ziling and Li Lao very politely, and then exited the office.

"You're going to play yours too, I need to go out of town these days, and I'll let you know when I get back to Africa." The girl left, looking at Du Hui's eyes, he also knew that his thoughts were only on her at this time, and there was nothing left for the two brothers and sisters to stay here, Xu Ziling simply waved them away.

There were three people left in the room, Xu Ziling didn't stay too long, and told Li Lao about some school things, and agreed to start his first lecture in ten days, and he led Xia Xueyi out of the University of Science and Technology.

The Eagle Eye Satellite is now lying in the assembly workshop of the Northern Satellite Launch Center, just waiting for Xu Ziling to write some software into the core, so he did not delay, in the afternoon, the group got on their Gulfstream 550, left Star City, and went to the Northern Satellite Launch Center.

After lunch, we set off and arrived at the launch center in the desert, which was just before four o'clock in the afternoon.

Compared with the last time they came here, Xu Ziling and the others had their own plane this time, and they did not need to take a plane to Lanshi and then take a car for hundreds of kilometers into the desert, but directly landed the plane at the small airport of the satellite launch center.

It was an acquaintance Director Cao who came to receive him, as soon as he got off the plane, he enthusiastically stretched out his hand, and said to Xu Ziling with a smile: "Xu Gong, welcome and welcome, goodbye before, it has been a few years in the blink of an eye." ”

Face is given to each other, people are so polite, of course Xu Ziling can't be rude, he held Director Cao's hand tightly and shook it: "Yes, it's been a few years in the blink of an eye, there are too many trivial things on weekdays, and I can't come to visit Director Cao, I'm really embarrassed." ”

"Where...... Where ......"

After a few polite words, Xu Ziling introduced the people around him, and after greetings, under his leadership, boarded the bus and headed to the central base.

Close contact with satellite launches, whether it is Yang Kaiming or Xia Xueyi, is an attractive thing.

The day after arriving, Xu Ziling began to get busy, and several of them visited the launch center and assembly workshop with relish.

They are happy to play, but Xu Ziling is a little busy here, this time is different from the last time with the help of Professor Xie's team, only a group of people from the Great Wall Company, among which there are several powerful experts and technical personnel, but compared with Professor Xie and them, it must be a grade lower.

Therefore, many things need to be done by him, so his personal working hours have greatly increased.

After three busy days, the satellite was finally loaded with a rocket, and then after another three days of debugging, all the preparations before the launch were completed.

On the scheduled launch date, there was nothing unusual about the weather, with light winds, clear weather, and high visibility, all of which were suitable for the launch conditions.

Early in the morning, all the personnel of the launch center began to be busy, moving the rocket from the assembly workshop to the launch platform, filling the rocket with fuel, and testing various systems such as communication, monitoring, and power.

After everything was done, it was afternoon.

Three o'clock is the time for the launch of the plan.

After up to 7 hours of pre-launch preparation, the solid rocket can be used to start ignition when the countdown reaches zero.

Takeoff, booster stage separation, first-stage rocket separation, second-stage rocket ignition, second-stage rocket second ignition, entering the transfer orbit, two-stage rocket separation and orbit change engine apogee ignition.

Nine minutes later, the satellite reached its designated orbit.

Orbit change, attitude adjustment is completed, and the satellite solar panel is deployed.

The satellite officially began to work.

Since it is in low orbit, the launch does not take a long time, from the ignition, to the satellite's computer startup, system initialization, and then start working, the whole process is less than an hour.

"Launch successful!" When Xu Ziling connected to the satellite, he was very excited, this was the first satellite belonging to their military factory.

Compared with the previous "Eagle Eye" satellites, this time they use some differences, for example, in terms of communication, they are more advanced than the two previously launched, and the capacity has also increased a lot.

It's just not these things, he didn't tell anyone.

Compared with the country, Xu Ziling also needs two, this one was successfully launched, and there is another one, in the plan, the time to launch the other one was the evening of the next day, so on that day, everyone did not celebrate, but waited for the second one to also be successful, and then celebrated.

The cost of a satellite is nearly one billion US dollars, Xu Ziling of course will not allow it to fail to launch, on the first day of coming, he asked the lion to inspect the rocket and satellite, and only agreed to launch after making sure that there was no abnormality.

Otherwise, he would never have allowed his satellites to disappear into space or fall from the sky.

Continuous launches, in the Northern Satellite Launch Center is not rare, but it is not uninitiated, there is previous experience, the next afternoon, all the personnel on the pre-launch preparations, and then at night on time to carry out the launch.

Ignited again, the rocket did not have any problems, the first stage rocket separated, the second stage rocket separated, and then entered orbit, the satellite began to work, and the whole process was exceptionally smooth.
