December 31, 1965, in the small town of June Fourth in Northwest China.
Today is sunny and sunny, which can be regarded as a rare good day.
However, the temperature is a bit frighteningly low, with 17 or 18 degrees below zero. It can only be said that in the desert, the sun's temperature cannot be retained at all.
In the early morning, Zhou Jimin returned to the capital, had breakfast with his family at home, and then came to Wenjin Street.
By the time he got here, his vehicle and his outfit had been changed to a panda vest.
At the door of the office, the old man had already put on a gray tunic suit and a hat.
Zhou Jimin stood up straight and said, "Leader, I'm ready. Do you want to leave now?"
Let’s go!
The old man nodded solemnly and said only these two words.
Next, unlike that day's itinerary, the 65 supersonic plane parked directly on the runway in the suburbs.
This place is deserted, with no one within a radius of more than ten kilometers.
The plane climbed into the air and headed northwest.
After arriving near the June Fourth Town, we did not land at the airport, but went directly to the launch tower.
At this moment, many people gathered at the control center near the transmitting tower.
Many people in the small town came. It was basically the first time for both ordinary residents and scientific researchers to see such a major event as satellite launch.
After landing, not long after greeting everyone, the old man asked Zhou Jimin why he wanted to launch two satellites?
"No need to wait, today is a good day..."
The latter didn't explain more, but the elderly actually understood it.
Regarding scientific research, Zhou Jimin’s advice is correct.
At the control center, the old man, accompanied by Wang Ping'an and others, listened to Zeng Qingfeng's explanation.
However, Zhou Jimin had already arrived at the transmission tower at this moment, and he needed to confirm again.
He checked all the liquid fuel, gyroscope, calibrator device, positioning system device, camera, etc.
After confirming that there were no discrepancies, we left the tower.
Returning to the control center, Zhou Jimin saluted the old man:
"Leader, the Shenlong-1 satellite rocket is ready, please approve the launch mission!"
At this moment, everyone in the audience looked at the old man and Zhou Jimin. Some were excited, some were nervous, some were curious, and so on.
"Approved!"
The powerful voice resounded throughout the entire control center.
After receiving the order, Zhou Jimin immediately ordered everyone to prepare. The countdown was quickly displayed on the big screen in front of the control center hall.
The countdown started from one hundred seconds, and everyone held their breath and stared.
It was the first time for everyone to watch a satellite launch, but they also felt the tense and exciting atmosphere.
At the same time, we also saw all the preparations made by the satellite research team led by Zhou Jimin.
Three!
Two!
One!
As the countdown ended, Zhou Jimin pressed the start button, and the base of the transmitting tower in the distance instantly sprayed out white gas.
Soon there was a flame, a purple-red flame, especially gorgeous.
Immediately afterwards, amidst the earth-shaking roar, the rocket slowly took off. When it reached a height of more than 100 meters, it suddenly accelerated and went straight up.
At the ground control center, all technicians are working nervously and observing all the data.
"The rocket is flying on the predetermined orbit and the flight speed is stable..."
"At an altitude of three thousand meters, everything is normal now. It has accelerated to..."
"The Shenlong-1 rocket is adjusting its direction and is about to reach the predetermined altitude of 70 kilometers. The first-stage rocket fuel capsule is about to leave..."
"Secondary engine ignition is successful, continue to accelerate..."
The entire control center echoed with the announcer’s voice.
Remote telescopes on the ground monitor the trajectory of the rocket after liftoff. It is estimated that it will not be able to monitor it after the second stage rocket cabin separates.
At that time, all we can do is look at the relevant flight data and pictures transmitted back from the satellite.
"Boss Panda, are we almost successful?"
At this moment, Xu Lei, who was standing next to Zhou Jimin, asked a slightly idiotic question with trembling lips.
The former shook his head, "The second-stage rocket capsule has not separated yet, and the fairing has not fallen off yet. It is far from a success. However, everyone waits patiently. It will be soon..."
Under the eyes of everyone, the fairing soon fell off, and the rocket had reached the predetermined height and speed.
Immediately, the second-stage rocket shuts down and separates. With the energy obtained and the gravity of the earth, it begins an inertial flight until it reaches a position tangent to the predetermined orbit.
At this time, the third-stage rocket engine ignited and began the final acceleration phase of flight.
When it accelerates to the predetermined speed, the third-stage engine shuts down, and the rocket's carrying mission is completed.
Buzz!
With the mission of the rocket completed, it can basically be determined that the satellite launch has ended perfectly.
Zeng Qingfeng and other scientific researchers know the process best, so they immediately cheered.
For a time, the entire control center fell into a sea of joy.
In space, satellites have begun to work according to established procedures.
The computer control system of the supercomputer, under the previously set program, spreads the solar panels on the two wings of the satellite, and at the same time, various tasks are about to begin.
On the ground, after cheering, Zhou Jimin stared at the signal receiving display screen.
Everyone also became quiet.
After a while, as expected, a happy sound and picture came.
Success!
The ground signal tower and the satellite signal are successfully connected, and then the satellite launch is considered a complete success.
The old man was very happy and there were tears in the corners of his eyes.
"Comrade Panda, do you think it is possible for us to catch up?"
There was no one else around where the two of them were standing. Everyone was cheering loudly and celebrating, and they didn't seem to notice them.
Zhou Jimin knew very well what the old man meant, which was to ask if it was possible to catch polar bears and bald eagles.
This chapter is not over yet, please click on the next page to continue reading!
After all, in terms of land area and population, the mainland is currently among the top three countries in the world.
However, in terms of economic strength, military strength, technology, etc., the mainland is extremely backward.
A few years ago, we still had to find people to buy food to survive the cold winter of famine. Now, the problem of enough food for everyone has not yet been completely solved.
How about catching up with polar bears and bald eagles?
However, Zhou Jimin will not talk about these important matters foolishly, because this is not something he can discuss, let alone what he should pay attention to.
"Leader, I remember a saying that goes like this: if you get fat first, you won't be fat, but if you get fat later, you will lose weight."
After pondering for a moment, Zhou Jimin said in a roundabout way:
"We have now successfully launched the first satellite. After dinner in the afternoon, we will launch the second satellite immediately..."
"After this stage is completed, we will start developing medium-altitude satellites and geostationary satellites..."
"We will continue to develop manned satellites and other scientific research projects later..."
"But, leader, these are very expensive, and the demand for talents is also very large... You may need to be mentally prepared."
His outspokenness impressed the old man.
Of course, the old man didn't say anything. He just said that you just have to work hard and leave the logistics support to them.
"Leader, you are not an old man, you are getting stronger and stronger..."
"Haha, yes, I am ambitious for a thousand miles."
The two looked at each other and laughed.
At three o'clock in the afternoon, not long after lunch, the second satellite launch mission was about to begin.
This time it is a fixed rocket launch mission, and it is also a low-latitude reconnaissance satellite.
There is no way, technological breakthroughs always start from the simplest and then advance step by step.
It is impossible to launch geostationary satellites at once, that would be awesome.
The lifespan of reconnaissance satellites is very short, usually about 21 days.
I don’t know if the two satellites developed by Zhou Jimin can survive a month.
By evening, the second satellite had successfully entered its intended orbit.
At this time, it can basically be announced that the satellite launch mission was successfully completed.
The next stage is the research and development mission of a medium-altitude, one-year-life satellite.
The tasks at this stage will be more important, and the difficulties can be imagined.
However, the breakthrough from zero to one has been achieved, and it will not be so difficult to go from one to two to three.
That night, the entire June Fourth town fell into a carnival.
The screens in several canteens have already started playing New Year’s videos.
Today is the last day, and tomorrow is New Year’s Day.
Therefore, it is not abrupt at all to play a Happy New Year music video at this time.
On the contrary, the old man who stayed in the cafeteria to eat was watching the TV with great interest.
Not only is the melody of the song "Happy New Year" nice and the lyrics festive, but also because the short film is well produced and looks like it has a New Year atmosphere.
"Comrade Panda, you made this too?"
"No, it's purchased from the island..."
Zhou Jimin immediately denied it and refused to admit it even to death.
Anyway, Xiaoyue's facial features are more like Xu Mei's, so there is no need to worry about people finding out that this is his child.
Moreover, he is now wearing a panda vest, which is very different from his original appearance.
"It's pretty good. It sounds great. Can I take some to the capital?"
"Leader, this matter is not my responsibility. Besides, how many TV sets can there be in Beijing? And the price of a music video is not cheap. I'm afraid not many people in Beijing can afford it..."
"You kid can definitely afford it, haha, don't look so grim, let's go, we're going back."
"Okay, leader, I'll see you off."
Not to mention, the small town at this time, because of the song "Happy New Year", the atmosphere of the New Year is instantly full.
In addition, the streets and alleys are filled with lanterns and other New Year decorations, which is really amazing.
On the way back, the old man praised it again and said that the June Fourth town had done very well in these aspects.
Zhou Jimin mourned for the leaders of the capital city in his heart. He estimated that they would suffer a disaster after returning.
After arriving at Wenjin Street, Zhou Jimin went home.
"Dad, why did you come back just now? We have finished eating the chicken legs, and there is no more for you..."
As soon as they got home, Xiaoxian and the others held his arms and muttered.
There is some emotion in the tone.
New Year's Day can be considered a small holiday, but if dad is not at home, it is not a reunion.
Holding the children in his arms, Zhou Jimin smiled and said to them, I will eat them tomorrow, but you are not allowed to snatch them from me.
"No, we have to rob it and not give it to daddy, hehehehe!"
"You're not a fat pig, why are you humming?"
Xiaoyi's nose was scratched by her father, and before she could say anything, Xiaoxian and the others started to hum.
"We are little pigs, dad you are the big pig..."
Even Xiaowan and Xiaojing, who were not very fluent in speaking, also hummed, which made Zhou Jimin smile.
What about Big Pig? Is he that fat?
"Since you like pigs so much, would you like me to teach you a pig song?"
"Okay, dad, teach me quickly!"
In an instant, it hit the vital point of the children, and they suddenly became excited.
After being noisy for half a night, the children also learned the Pig Song to a great extent.
It's New Year's Day soon, and this day is all about playing.
Although it didn't snow, it was cold and not many people were hanging out outside.
After playing with the children all day, they will return to study in the evening.
The final exam is in two days. If they don't hurry up, they may get zero marks in the exam.
"No, I still got full marks this time!"
Several children were very confident. The little goldfish next to them said: If you are too confident, don’t cry if you don’t do well in the exam.
If the third or fourth uncle said this, the children would definitely refute it, but if my sister-in-law said that, then forget it.
Can't win!
Because the little goldfish’s grades have always been very good, and he has skipped a grade in school. He will be in the third grade of junior high school next fall.
Therefore, they can only pretend not to hear.
Everyone couldn't help but laugh when they saw Xiaoxian and the others calm down and acting like ostriches.
"Humph!"
The children who were immersed in their homework looked up and hummed, then continued to read with their heads down.
Xiaojing's two children also hummed along, imitating their elder brothers and sisters, and reading books in a decent manner. They are very cute.
The New Year's Day festival has passed in a hurry, and the Spring Festival will be here soon.
After staying at home for two days, Zhou Jimin returned to work in the June Fourth town.
Today we are going to hold a seminar on research and development of satellites, mainly on project planning, personnel allocation and other aspects.
The first is to divide a group of technical personnel to follow up on the situation of the two satellites in the sky in the next month and a half.
The two satellites just launched a few days ago will transmit high-definition pictures and a large amount of data to the earth at regular intervals, which will play a very important role in the subsequent scientific research work.
Therefore, this is an item that must be prioritized and cannot be ignored.
The second is the subsequent research and development of medium-altitude satellites. This is more difficult research and is also very important.
"Hello, Andy, help me distribute these materials..."
In the conference room, regarding the second topic, Zhou Jimin interrupted Zeng Qingfeng’s speech and asked Andy next to him to help pass on the information.
"Have you all seen the information? The above is my latest design for reconnaissance satellites, as well as the technical development of related materials..."
The altitude of reconnaissance satellites is very low. Affected by the atmosphere, their lifespan is generally about seven to twenty days.
Because it is close to the earth, the reconnaissance satellite has a very good monitoring effect on the ground, and the information transmission speed is also very fast.
Unlike synchronous satellites, which are far away from the earth, it is almost impossible to transmit pictures and videos.
Unless technology develops in the future, it will be difficult to break through.
Of course, by that time, directly launching rockets to build a space station will definitely be more powerful than satellites.
Zeng Qingfeng and others looked down at the materials. No one spoke, they were all listening quietly.
According to Zhou Jimin's explanation, the height of the reconnaissance satellite he designed and improved is actually at a mid-altitude position.
Secondly, great improvements have also been made in terms of external coatings and materials.
The most important thing is the signal transmitting device, which is the most valuable part of the entire material.
After just watching for a while, Zeng Qingfeng and the others were so excited that they looked at Zhou Jimin as if they were looking at gods.
"Boss, is this really achievable?"
There is a reason for their excitement, because once the research and development is successful, it is very likely to establish a navigation system.
Although it requires a huge amount of money, as the saying goes, if you hear the truth in the morning and die in the evening, it is nothing more than that.
Just think about it, navigation systems all over the country and even the world, how incredible is this technology?
"Whether it can be realized or truly implemented depends on your efforts, not on these materials..."
Zhou Jimin shook his head, he was not excited at all.
It's just a piece of material, and it doesn't really turn the technology into a physical object.
What's more, even if it is a physical object, it is not 100% able to be sent to the sky, and then the technology can truly transform from paper to real life.
What happened before has raised Zhou Jimin's vigilance to the highest level.
Therefore, he appears here and plans to stay here often in the future.
Later, he reiterated the safety issue again.
And regarding this matter, Xu Lei and the heads of the other three research institutes were called over for a meeting.
"All research work must be carried out on the premise of safety, and the previous solid rocket technology incidents must not happen again..."
After repeated instructions, Zhou Jimin said that in the next few days, until the Spring Festival, he would work in the small town every day during the day.
Buzz!
Hearing the news, Zeng Qingfeng and Xu Lei were so happy that they invited him to their respective research institutes for guidance.
"Don't be anxious, I haven't finished speaking yet, why are you anxious?"
Seeing their excited expressions, Zhou Jimin was relieved and at the same time dumbfounded.
"I will work in my own research institute. I have my own research to do. If you don't understand anything or need to discuss it together, we can solve it together during lunch..."
He is pressed for time more than anyone else.
But he can't stay here all the time, so staying in the small town during the day and going home to sleep with his wife and children at night is the best way to deal with it.
Of course, in this way, he needs to spend more than two hours every day commuting, which is a bit of a waste of time.
But there is no way, some things must be done.
Besides, he may not have wasted the commuting time.
