Chapter 751: Which star should I get?
Although the personnel adjustment was a big deal, for Gao Zhendong himself, there was not much change. The Third Factory was still the same Third Factory, and daily production and administrative management were taken over by others. The only difference was that it was Yan Chengde before and it is Zheng Liangshu now.

Gao Zhendong's main work recently is still to study chemistry books. That expensive paper is a completely new field for him. The paper is relatively in-depth and the results are new, but it is not based on a completely new theory. He can't just throw it out before he understands it.

This is different from the groundbreaking things mentioned above. He can make up whatever he wants with those things. At most, they are just what he got in a dream and can become a good story.

But this won’t work. If you rashly bring it out without understanding it yourself, you’ll just end up making a fool of yourself.

"…with malononitrile as the starting material…"

"…the first intermediate is monoclinic…"

"…After recrystallization from ethanol, the third intermediate shows triclinic crystal system…"

"…The synthetic route is…"

This is a big challenge for Gao Zhendong, whose mind is full of electronics, metal materials, computers, and software. Especially since he cannot extract relevant teaching materials from the system, it still takes a lot of effort for him to understand this stuff.

It was impossible to extract the textbooks from the system. Firstly, they were too expensive. Even if he wanted to read them, they would not exist. Secondly, chemistry was quite far from his major. He had never read most of the basic professional textbooks such as inorganic chemistry, organic chemistry, electrochemistry, analytical chemistry, physical chemistry, structural chemistry, etc., and could not extract them at all.

Fortunately, the basic theory of chemistry has not developed much. With the university chemistry textbooks of these days, you can still verify and absorb some things. As long as you reach a certain level, you can fool people.

At least it can fool people, so we can take it out and find Mr. Xiang and others who are engaged in urea technology and engineering plastics to proceed to the next step. Otherwise, if we say that this thing was made up out of thin air, no one will believe it.

As for whether Mr. Xiang is familiar with this branch, that is another question. He is not, but he can find someone who is.

The paper is divided into several parts. Another part is another thing, another synthesis route, which Gao Zhendong still has to work on.

While Gao Zhendong was taking a break, the phone rang.

The call came from the Defense Work Committee: "Comrade Zhendong, please come to the Defense Work Committee right now. There is an important meeting that needs your participation."

Gao Zhendong put away his thesis, got in a car and rushed to the Defense Work Committee.

While Gao Zhendong was still on the road, in a conference room, the leaders of the Defense Work Committee, the chief engineer, and several comrades were discussing something.

"Leader, Gao Zhendong has never been involved in this direction before, right? Is there little point in inviting him?" asked the chief engineer.

"At least he knows something about the Rockets, and he's smart. If it's a question of whether to do it or not, there's no need to ask him to come. But if we're discussing what to do, maybe asking him to come can yield some different results."

When Gao Zhendong rushed to the Defense Work Committee without stopping, he saw this scene. Each person had several reports in front of them. They looked similar and they were probably doing some kind of argumentation or discussion.

Seeing Gao Zhendong coming, the leader pointed to an empty chair and said, "Zhendong, sit down and take a look at this."

After saying that, he handed a set of materials in his hand to Gao Zhendong. It seemed that he had not expected that he would be needed to attend the meeting, but for some reason, he was still called over.

Gao Zhendong turned his gaze to the materials in his hand, and his eyes widened when he saw them.

"Preliminary Thoughts on the Development of Artificial Satellites"

"Suggestions for early launch of artificial satellite projects"

"..."

These are several proposals on the development of artificial satellites. Although the names of the reports are different from those he knew in his previous life, the names on them are still very familiar to Gao Zhendong. They are well-known and famous.

The reason why Gao Zhendong widened his eyes was that this matter was brought forward too much. We originally proposed satellites very early. We had the idea in 58, but due to economic, technical and other reasons, it was not officially launched until 65, and it was not launched until 70. However, we did not develop one satellite at a time. In fact, the research on the second satellite was started long before the first one was launched. Therefore, the second satellite was launched relatively quickly, and its structure and mission were very different from the first one.

It's only 62 years now! But Gao Zhendong thought about it carefully, it seems to be about the same. In his previous life, he knew that he started working on satellites after Miss Qiu got married. If we calculate it based on this node, it doesn't seem too outrageous to start considering it now?

Gao Zhendong quickly browsed through the materials, while the leaders and comrades beside him were still discussing this topic.

He put down the materials and listened for a while.

During a break in the speeches, the leader turned to him and asked, "Zhendong, what do you think after reading this?"

Gao Zhendong shook his head: "Not yet, has it been decided to do it now?"

The leader also shook his head: "Not yet. We are discussing various aspects now. We are discussing other things like rockets, launches, telemetry support, etc. Today, we are discussing the functions of the satellite itself. You have a smart mind and many clever ideas, so I called you over to listen together."

Gao Zhendong finally understood that this was part of the preliminary planning work. He did not rush to speak, but listened to what others were saying.

"I think that the first satellite should not be used for scientific research. It should mainly prove that we can launch a satellite into space and maintain normal operation for a period of time."

"Proof? How to prove it?"

"I think it can be summarized into a few points: we can hit it, hear it, and observe it."

Upon hearing this comrade's idea, Gao Zhendong almost laughed out loud. This idea was actually similar to the requirements for the first artificial satellite: "able to go up, be able to catch, be able to hear, and be able to see." However, the "ability to catch" aspect of satellite telemetry was temporarily put aside.

"Spend so much money just to hear a noise?" Some comrades still have some doubts.

"If we can hear the sound, it proves that the technology is effective."

"I think we still need to carry some mission payload up there, as resources are limited."

"..."

Seeing that Gao Zhendong had been listening for a long time and was gradually getting into the mood, the leader turned around and asked Gao Zhendong: "Comrade Zhendong, what do you think?"

Gao Zhendong thought for a while. He actually had some understanding of satellites, which were highly relevant to the military.

Read the error-free version at 69shuba! 6=9+shu_ba is the first to publish this novel.

"If it is a long-term plan, planning a series of satellites, then we can do anything, but for the first one... I guess there won't be much we can do. Communication satellites are usually in synchronous orbit, which is too high. It's not realistic to launch the first one that high."

The synchronous orbit is tens of thousands of kilometers high. It goes without saying that it is impossible for the first satellite to reach that high.

Although Gao Zhendong said this, other comrades knew as soon as they heard it that this comrade had some knowledge about satellites. Being able to talk about the synchronous orbit at this time can definitely be regarded as someone who has a relatively good understanding of satellites.

Gao Zhendong continued his thoughts: "For the same reason, broadcast satellites and the like are not suitable either."

Although our first satellite broadcasts music in space, it is not a broadcasting satellite in terms of type. Broadcasting music is just a way for it to prove its existence. In fact, the satellite does not have the actual function of a broadcasting satellite.

At this point, Gao Zhendong knew what he should do.

"Leaders and experts, if you want to know what function the first satellite will have, I can't say. Sometimes the first satellite is not entirely based on technical considerations. But I do have some ideas about what the second satellite will do."

The leader was amused by Gao Zhendong's sly remark: "Then tell me about the second one."

Gao Zhendong said: "For the second one, I suggest that it can be made into a test satellite to test the power supply system, detect the basic outer space environment, telemetry system, etc. From the third one onwards, we can consider a recoverable satellite or a camera satellite, and we can also start to consider launching satellites into synchronous orbit."

As for the idea of ​​hitting a synchronous orbit satellite, Gao Zhendong has not yet considered the big task of the entire global satellite positioning system. Our satellite positioning system covers more orbits than just the synchronous orbit. This thing is really not something we can handle now, but for communication satellites, it is possible. The geostationary orbit where communication satellites stay is a type of synchronous orbit.

Even if the synchronous orbit cannot be hit, it seems possible to hit a few photographic reconnaissance satellites in low orbit.

Although it took a total of five years from 65 to 70 to launch the satellite into space, in fact, our satellite did not enter the detailed design until 5, which was still a very fast pace.

If I'm lucky, maybe it can be used again? Gao Zhendong thought to himself.

"Photograph?"

"Yes, photography, whether it is a returning film capsule or remote transmission, as long as the camera resolution and transmission speed reach a certain threshold, photography is useful, such as for crop yield estimation, disaster prevention and mitigation, land resources survey and assessment, etc."

Gao Zhendong said it seriously. This is not what I said. I heard it on TV in my previous life.

The leader of the Defense Work Committee almost laughed when he heard this. This kid is quite cunning. He knows how to tell lies with open eyes. However, it is not all lies. These things can really be used.

"You've got to put something this expensive up there and just look at these contents? Agricultural yield estimates can be done by comrades in the agricultural sector."

"Then let's make it a transmission type, then it can do more things." Gao Zhendong was still serious.

"Can our communications technology support it?"

"Sometimes, even if you can only upload one photo a day, it can play a big role, such as disaster assessment..." Gao Zhendong got involved in disaster prevention and mitigation.

"And, when transferring photos, it's not just the communications technology that can affect performance."
