Two days later, Xu Ziling left for home again.

Traveling with him were Yang Kaiming, Li Cheng, Duan Zhan, Xia Xueyi, and then the Du family brothers and sisters.

Yang Kaiming and the other grown men are of course responsible for security, Xia Xueyi is the assistant, and the Du family brothers and sisters are just soy sauce.

Originally, I planned 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, it is the time when freshmen enter the school. As the car drives to the school gate, Xu Ziling looks at a pair of armed sentries on both sides, as well as the freshmen and their parents who are welcoming them.

I was filled with emotion.

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

It's true or not it's a lie.

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

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

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

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

"Okay." Du Hui was not sure whether he could pass the "interview", so he nodded, took out his cell phone and started to contact his classmate.

"Come over in about ten minutes..." The call was quickly hung up, and he raised his head to explain to Xu Ziling.

"Well, wait here for a moment, let's go up first." Xu Ziling could imagine that Du Hui would definitely be with his classmate, so he didn't even ask him if he wanted to go up together. After saying that, he called a few others to go upstairs.

.

Li Litian is still the dean, and it is the time when freshmen are about to start school. Of course, there are a lot of things going on. When Xu Ziling and others arrived in his office, they saw him and a few people talking about something.

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

A few minutes later, Mr. Li was heard saying: "Just follow this plan and distribute it quickly."

"Okay." Several people nodded in agreement and then left the office.

"Mr. Li. (Teacher.)" Seeing that they were finally done, Xu Ziling and others immediately stood up to say hello.

"Sit, sit." Li Litian asked several people to sit down, and he also sat down on the sofa. He smiled at Xia Xueyi and Du Hui nodded, and asked how they felt about being in Nitan.

After the two of them answered, they started talking to Xu Ziling.

Of course, we are talking about Du Hui and his students.

"Not bad." Xu Ziling said with a smile. In the past two months, the Du Hui brothers often stayed up all night to figure out a problem before resting. He was very satisfied with this motivation for learning, "

Both of them are good talents, and given a few years, I guarantee that two good experts will be born in the field of materials."

"Really?" Mr. Li immediately became happy after hearing Xu Ziling's words. He is an expert in materials. The field of materials has always been the country's weakness. Being able to produce several young experts, of course he has reasons to be happy.

.

…

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

The girl was twenty-three or four years old. She had long hair and was not very pretty. She was an attractive type. She came in with Du Hui and greeted a few people politely.

Xu Ziling had special training in observation. For ordinary people, whether what he said was true or false could not escape his eyes. After that, Du Hui introduced this girl named Fu Feixia, and he kept observing.

After asking a few questions and making a few jokes, he had a rough assessment of this girl in his mind.

Without rushing to give an answer, Xu Ziling asked her to go back and wait for the news.

"Originally I didn't take students, but Du Hui strongly recommended you, so I came here today. Let me explain to you first, if you really want to learn something, rather than just for a graduate degree, then once you become my

students, just like Du Hui and others, need to go abroad,

And the course will not be too easy, you should think about it first... I will give you an answer in a week, but when I give the answer, it will be when you leave the country, so you should think about what I said first.

In case you don’t want to go when the time comes...Okay, you can go back first."

She didn't expect to reply right away. After Xu Ziling finished speaking, he asked her to go back and wait for the news. The girl didn't say much. She politely said goodbye to Xu Ziling and Mr. Li, and then exited the office.

"You guys go and have fun. I need to go somewhere else these days. When I return to Africa, I will let you know." The girl left. Looking at Du Hui's eyes, she knew that he was probably thinking about everything at the moment.

With her on her body, the two brothers and sisters had nothing to do if they stayed here. Xu Ziling simply waved them away.

There were only three people left in the room. Xu Ziling did not stay too long. He talked to Mr. Li about some school matters and agreed to start his first lecture in ten days. Then he led Xia Xueyi out of the University of Science and Technology.

The Hawkeye 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, a group of people got on their Gulfstream 550, left Star City, and headed to the north.

Satellite launch center.

After lunch, we set off and arrived at the launch center in the desert just before 4pm.

Compared with the last time we came here, Xu Ziling and the others had their own plane this time. They did not need to fly to Lanshi and then drive hundreds of kilometers into the desert. Instead, they landed the plane directly at the small airport of the Satellite Launch Center.

.

The person who came to receive us was an acquaintance, Director Cao. As soon as he got off the plane, he warmly extended his hand and said to Xu Ziling with a smile: "Xugong, welcome, welcome. After we said goodbye before, it's been a few years in the blink of an eye."

Face is given to each other, and people are so polite. Of course, Xu Ziling can't be rude. He held Director Cao's hand tightly and shook it: "Yeah, it's been a few years in the blink of an eye. There are too many trivial matters on weekdays, so I haven't been able to visit Director Cao.

, I’m really sorry.”

"Where...where..."

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

It is an attractive thing for both Yang Kaiming and Xia Xueyi to have close contact with satellite launches.

The next day after arriving, Xu Ziling started to get busy, while the others visited the launch center and assembly workshop with great interest.

They had a good time, but Xu Ziling was a little busy here. This time, unlike last time, Professor Xie's team had help, only a group of people from the Great Wall Company, including several powerful experts and technicians, but with Professor Xie and the others

In comparison, it is definitely on a lower level.

Therefore, many things require his own hands-on work, which greatly increases his personal working time.

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

On the scheduled launch date, there were no abnormalities in the weather. There was light wind, clear weather, and high visibility. All conditions were suitable for launch.

Early that morning, all the personnel at the launch center started 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 is done, it's afternoon.

Three o'clock is the planned launch time.

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

Take-off, booster stage separation, first-stage rocket separation, second-stage rocket ignition, second-stage rocket secondary ignition, entering the transfer orbit, second-stage rocket separation and orbit change engine ignition at apogee.

Nine minutes later, the satellite reached the designated orbit.

Change orbit, complete attitude adjustment, and deploy satellite solar panels.

The satellite officially started working.

Because it is in close orbit, the launch does not take a long time. From the ignition, to the satellite's computer startup, system initialization, and then starting to work, the whole process takes less than an hour.

"The launch was 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, the one they use this time has some differences. For example, in terms of communication, it is more advanced than the two previously launched, and its capacity has also increased a lot. There is no need to transfer it at all.

signal conversion, but directly uses satellite signals.

It's just that he didn't tell anyone about these things.

Compared with the country, Xu Ziling also needs two. This one was successfully launched, and there was another one. The plan was to launch the other one on the night of the next day, so on that day, everyone did not celebrate.

It is to wait for the second one to be successful before celebrating.

The cost of a satellite is nearly one billion U.S. dollars. Of course, Xu Ziling would not allow its launch to fail. On the first day he arrived, he asked Lion to inspect both the rocket and the satellite to make sure there were no abnormalities before agreeing to launch.

.

Otherwise, he would never let his satellite disappear into space or fall from the sky.

Continuous launches are rare at the Northern Satellite Launch Center, but it is not unheard of. With previous experience, all personnel started the pre-launch preparations skillfully from the afternoon of the next day, and then launched on time at night.
Chapter completed!
