Two days later, Xu Ziling set off for home again.

Along with them were Yang Kaiming, Li Cheng, Duan Zhan, Xia Xueyi, and then the Du brothers and sisters.

Yang Kaiming and the others are of course in charge of safety, Xia Xueyi is an assistant, and the Du brothers and sisters are all in charge of soy sauce.

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

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

Every September, when freshmen enter the school, the car drives to the school gate, and Xu Ziling looks at a pair of guard posts with live ammunition on each side, as well as the incoming freshmen and their parents.

I was very emotional.

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

It's really not a fake.

Under the leadership of Yang Kaiming and Li Cheng, I can still vividly remember the first time I entered USTC, as if it was just yesterday.

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

How could he have thought of this kind of change?

Slowly entering the gate, Xu Ziling went directly to the Materials Department, stopped the car in front of the teaching building, and 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 mobile phone and started contacting his classmate.

"Come here in about 10 minutes..." The phone hung up quickly, and he raised his head and explained to Xu Ziling.

"Well, then you wait here for a while, let's go up first." Xu Ziling could think that Du Hui would definitely go up with his classmate, so he didn't even ask him if he wanted to go up together. After speaking, he called the others to go upstairs .

Li Litian is still the dean now, and it is the time when the freshmen start school, and of course there are many things. When Xu Ziling and the others arrived at his office, they saw what he was talking with a few others.

Seeing Xu Ziling and the others come in, he just pointed to the sofa next to him to signal them to sit first.

A few minutes later, I only heard Mr. Li say: "Just follow this plan, and distribute it quickly."

"Okay." Several people nodded and left the office.

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

"Sit, sit." Li Litian asked them to sit down, and sat down on the sofa himself. He nodded to Xia Xueyi and Du Hui with a smile, and asked them how they felt in Nitan.

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

Of course, it was about Du Hui and his students.

"It's not bad." Xu Ziling said with a smile. In the past two months, Du Hui's two brothers and sisters have often been able to stay up all night on a problem until they figure it out before resting. He is very satisfied with this kind of learning energy, " Both of them are good seedlings, 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 weak point of the country. He can produce a few young experts. Of course, he has a reason to be happy. .

……

About the graduate student, Xu Ziling had already had a preliminary communication with Mr. Li before. A few minutes later, the office door knocked and Du Hui came in with a girl. Mr. Li was not surprised.

The girl was 23 or [-] years old, with long hair, not very beautiful, but the good-looking type. She came in with Du Hui, and greeted several people very politely.

Xu Ziling had special training in observation skills. In ordinary people's words, whether the words were true or false could not escape his eyes. Afterwards, 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 evaluation of this girl in his mind.

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

"Originally, I didn't bring 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, not for a graduate degree, then once you become my The students, just like Du Hui and others, need to go abroad, and the course will not be too simple, you should think about it first... I will give you an answer in a week, but when I give the answer, it means you leave the country time, so you should think about what I said first, lest you don’t want to go when the time comes...Okay, you go back first. "

She didn't expect to reply right away, so after Xu Ziling finished speaking, she asked her to go back and wait for news. The girl didn't say much, and said goodbye to Xu Ziling and Mrs. Li very politely, and then left the office.

"Go play with you too. I need to go to other places these days. When I return to Africa, I will notify you." The girl left, looking at Du Hui's eyes and knowing that he is probably thinking about it right now. She was on her body, and there was nothing for the two siblings to stay here, so Xu Ziling simply waved them away.

There were three people left in the room, and Xu Ziling didn't stay for too long. He talked to Mr. Li about some school matters, and agreed to start his first lecture ten days later, and he led Xia Xueyi away from 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 core software, 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. It was just before four o'clock in the afternoon.

Compared with the last time they came here, Xu Ziling and the others have their own plane this time. They don't need to fly to Lanzhou City and then drive hundreds of kilometers into the desert. Instead, they land the plane directly at the small airport of the satellite launch center. .

The person who came to receive him was an acquaintance, Director Cao. As soon as he got off the plane, he extended his hand warmly and said to Xu Ziling with a big smile: "Xu Gong, welcome, welcome. It's been a few years since we left before."

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

"Where...where..."

After a few words of politeness, Xu Ziling introduced the people around him. After exchanging pleasantries, he boarded the car and headed to the central base under his leadership.

Whether it's Yang Kaiming, Xia Xueyi, or Xia Xueyi, it's an attractive thing to get close to the satellite launch.

On the second day after arriving, Xu Ziling started to get busy, while the others enjoyed visiting the launch center and assembly workshop.

They were having a good time, but Xu Ziling was a bit busy here. This time it was different from last time with the help of Professor Xie's team. There were only a group of people from the Great Wall Company, including a few powerful experts and technicians. In comparison, it must be a lower grade.

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

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

On the scheduled launch date, there is no abnormal weather, with light wind, clear weather and high visibility, all conditions are suitable for the launch.

Early this morning, all the personnel in 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 is done, it is afternoon.

Three o'clock is the planned launch time.

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

Take off, the booster stage is separated, the first-stage rocket is separated, the second-stage rocket is ignited, the second-stage rocket is ignited again, and enters the transfer orbit.

Nine minutes later, the satellite reached the designated orbit.

The orbit is changed, the attitude adjustment is completed, and the satellite solar panels are deployed.

The satellite officially started working.

Since it is close to the orbit, the launch does not take a long time. From the start of ignition, to the start of the satellite's computer, system initialization, and then start 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 is the first satellite belonging to their military factory.

Compared with the previous "Hawkeye" satellites, this time their own use is somewhat different. For example, in terms of communication, it is more advanced than the two launched before, and the capacity has also increased a lot. There is no need to transfer The signal conversion, but directly use the satellite signal.

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 is another one. According to the plan, the time to launch the other one is the next night, so on that day, everyone did not celebrate, but It is to wait for the second one to succeed before celebrating.

The cost of a satellite is nearly one billion US dollars. Of course Xu Ziling will not allow its launch to fail. On the first day of his arrival, he asked the lion to inspect both the rocket and the satellite, and agreed to launch after confirming that there were no abnormalities. .

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

Continuous launches are rare in the Northern Satellite Launch Center, but it is not uncommon to launch them before. With previous experience, starting from the next afternoon, all personnel were proficient in pre-launch preparations, and then launched on time at night.

Ignition 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 extremely smooth.
