On the morning of the third day after returning to China, Li Zhiwei and Xiao Yang went to the satellite launch site in the desert in the northwest of the country, because the launch time was in the afternoon, they arrived in the morning under the leadership of the launch site staff to visit the entire launch base, and even Zhao Nan and others allowed them to take pictures in several places.

The specific affairs are all taken by Mi Qilin to do it, Xiao Yang was idle for most of the day, except for chatting with the deputy minister of general assembly who came with Zhao Qingfeng in the afternoon, the rest of the time was either hanging out with Li Zhiwei, Xiao Ivan and others, or accompanying his wife and children to take pictures everywhere.

At two o'clock in the afternoon, the rocket was transported from the assembly workshop to the launch frame, half an hour, the rocket was erected on the launch stand, after inspection, the rocket began to be injected with fuel, at half past three, the fuel filling was completed, and finally the detection passed, the launch frame began to clear, Xiao Yang and others watched the final process of fuel filling accompanied by the staff, and then entered the safe range and began to wait for the launch.

"ICBMs, this thing is the carrier, right?" Little Ivan deliberately took a photo of the rocket at close range and sent it to Oman, who couldn't come, because of the comparison, Aman quickly called, "What is the height of the little bear?" More than 1.9 meters! Standing underneath the rocket, it's no different from a chicken, which is much better than the DF missiles we've seen before. ”

"That's definitely different." With the introduction of the staff in the afternoon, Xiao Yang has a more detailed understanding of this aspect, "The rocket used to launch the satellite is liquid fuel, and the DF missile we saw before is solid fuel, compared with solid fuel and liquid fuel, I think you should also know the difference, and this satellite is not the weight of an ordinary warhead, and can only use a rocket with the maximum thrust, so you are much larger than the DF missile." ”

"Satellite-launched rockets run on liquid fuel? I really don't know about that, but if it's so, I wonder how it's so much bigger than a missile. Aman suddenly realized that he knew that some rockets used to launch satellites were also suitable for missiles, but he didn't know that even if it was the same model, there were also types, and he understood when he heard Xiao Yang's explanation.

"Well, it's that simple." Now that he is learning and selling, Xiao Yang has no psychological burden at all, and he pulled Aman to explain the difference between the two, and then he showed off what he saw and heard today, and then he put it down with satisfaction.

Looking at his smug expression, little Ivan was speechless and said, "Is it really good for you to do this?" ”

Xiao Yang laughed, "Why is it bad?" Do you think this guy in Oman can't hear that I'm doing it on purpose? You guys...... Or is it too tender to come over when he has something important at hand? People are just for the roses, so ah...... Even if I talk for an hour, he has to listen honestly. ”

"......" Little Ivan and Addis opened their mouths wide, as if they had heard something incredible, and they were completely stunned.

How is that?

"He said he was busy, and I really believed it, but that's the case?" After a long time, little Ivan shouted, "When we go back, we must let him invite us to drink." ”

"yes, yes." Addis also nodded, "He hurt our feelings, we must make amends, otherwise we will not forgive him." ”

“……”

Xiao Yang rolled his eyes, with Aman's stinginess, it would be good to squeeze him with words, and he wanted him to drink? Isn't dreaming?

The launch of the rocket is not long, but it is absolutely shocking, especially at the moment when the ignition is lifted into the air, a huge flame erupts from the bottom of the rocket, emitting bursts of howls, that scene ......

As the countdown sounded, Xiao Yang and the others stopped talking, and looked at the launch pad in the distance with binoculars in their hands, and when the order to ignite was issued, they only saw the rocket spew out a puff of white smoke, and then orange flames came out, and then the rocket "slowly" took off into the air.

Ten meters, fifteen meters, twenty meters, as the altitude of the sky became higher and higher, the speed of the rocket became faster and faster, and in the end, it was even faster than their line of sight, and a white trajectory rose into the sky.

"That's it?" Only a few tens of seconds later, everyone only saw a faint light, and little Ivan put down the telescope and smacked his tongue, as if he was still unsatisfied.

"What else do you want?" Mi Qilin glanced at him, "Low-orbit satellites, you can enter the orbit range in ten minutes, you think about the speed, the human eye can only have that distance of sight, today can see for dozens of seconds, that is also because the weather is good, if the weather is a little worse, you can't see it for dozens of seconds." ”

When it comes to this kind of expertise, no one in their group understands it better than Mi Qilin, and when he said this, little Ivan found that he was speechless, so he could only shrug his shoulders and close his mouth very interestingly.

The satellite they customized belongs to the low-orbit satellite, but in terms of function, it is biased towards the comprehensive type, because it has a certain reconnaissance capability, but also has the ability to communicate, of course, this communication does not only refer to the communication of ordinary communication satellites, but can also be like a transit station, can quickly implement data transmission between satellites and satellites, satellites and the ground.

There are quite a few reconnaissance satellites in the world, and more than 100 of them have been launched in the United States and Russia alone, and when most of them can be controlled, there is no shortage of satellites in the information center, and the reason why such a satellite is customized is to speed up the data transmission between the satellite and the ground.

Directly transported on the original satellite, which is likely to cause the discovery of the country where the satellite is located, but through the satellite to control the satellite, the situation is different, after watching the launch scene, a group of people led by the staff to the command hall of the launch center, on the way Mi Qilin and Xiao Yang introduced the function of the satellite.

Of course, with Li Zhiwei here, he can't completely explain it.

"Although it is a low-orbit satellite, it can enter the orbit range in ten minutes, but it does not mean that the successful launch means that the satellite has entered the operational orbit, and it will take a period of fine-tuning to be able to officially enter, if nothing else, it should be about forty minutes, and our satellite can be used normally."

Arriving at the door of the command center, Mi Qilin stopped introducing, some of the things he said, Li Zhiwei can listen to them, because he doesn't understand these things anyway, plus the relationship between the two sides, let him know that it doesn't matter at all, but there are some things that they have to hide from others, even if the launch site and the person responsible for manufacturing satellites.

The place they watched just now was some distance away from the hall of the command center, and when they entered the hall, a person in charge immediately greeted them and told everyone that the satellite had been successfully launched into orbit and that it had now begun to enter the fine-tuning stage.

According to the general situation, the launch can be regarded as successful at the moment, so I can't help but say a few happy words, and then sit down and wait for the final result.
