The rejuvenation of a great nation: from educated youth to national treasure scientist

After the rocket is assembled, it must be quickly transferred vertically from the assembly and testing plant to the launch tower at the launch site.

This distance is 2.8 kilometers.

Vertical transportation is extremely difficult.

You know, this is a huge thing that is dozens of stories high and weighs nearly a thousand tons.

Transporting such an object to the launch tower is as difficult as walking several kilometers with a badminton racket in your hands, or even more difficult.

Therefore, transshipment is also a very difficult technical job.

The Long March 5 rocket was transferred to the launch tower and protected by the launch tower five days before the launch.

Next comes the most critical moment: waiting for the best time to launch.

Generally rocket launches take place in the evening, and the weather must be good, and there are strict requirements on wind direction and so on.

Of course, this is in normal times, ensuring the best launch results.

If there are special circumstances and the satellite must be launched into space as quickly as possible, it doesn’t matter if it’s windy or rainy.

On this day, the best window for launch finally arrived.

After communicating with Mr. Qian, Wang Haoran decided to launch the rocket at around 7 o'clock in the evening.

Before the launch, Wang Haoran and his staff conducted the final test.

Zhao Aiguo, chief engineer of Longguo Aerospace, followed Wang Haoran and was obviously a little nervous.

"Comrade Haoran, I think it is a bit risky to use a brand new hydrogen-oxygen engine in such an important launch mission," said Zhao Aiguo.

Wang Haoran looked at him and said with a smile: "Our engine has been tested many times. Generally speaking, there is no problem with safety."

Zhao Aiguo said: "It was mainly because of a rocket launch a few days ago. They exploded again. It exploded about ten seconds after it flew into the air."

"They've been working on hydrogen-oxygen engines for so long, but they still have major accidents from time to time. It's a bit unsettling."

Wang Haoran smiled and said, "The Squids were indeed early in the space industry, but I think they were very careless in their approach."

"To use a Chinese word, they are too sloppy."

“Their sense of responsibility is not as strong as ours.”

"Moreover, they have been engaged in happy education for a long time, and a large number of lower-class people have been educated into useless people."

"That's why they are more likely to have problems than us!"

"Besides, we can't throw the baby out with the bathwater because we are worried about other people's problems."

"To launch geosynchronous satellites and develop high-thrust rockets, you can't avoid hydrogen-oxygen engines."

Wang Haoran spoke eloquently and expressed his own views.

Zhao Aiguo smiled and nodded: "You are right."

"I guess there will be a lot of peepers during our launch, right?"

He said and looked up at the sky.

Wang Haoran knew what he meant, smiled and said, "This is inevitable."

"We can't stop them from spying with satellites."

"Maybe, their important officials are still staring at the satellite's spying images."

Reconnaissance satellites are low-altitude satellites that basically orbit the earth at a rapid speed.

So, they can just take a few glances, take a few photos, and then rush past.

In this day and age, high-definition satellite spy cameras are not mature enough, and the images are blurry to the point of exasperation.

However, this time, the three geostationary satellites launched by Brother Long all have extremely high-resolution synthetic aperture radars, which are much more advanced than Jusa's Keyhole series.

After all, their Keyhole satellites are only a few hundred kilometers high in space.

Brother Long’s satellite will be a geosynchronous orbit satellite!
From an altitude of more than 30,000 kilometers, it is theoretically possible to spy on the earth with an accuracy of decimeter level.

Most importantly, the area it scans is quite large.

Zhao Aiguo nodded and said, "So, we can't hide the fact that we launched a navigation satellite at all."

Wang Haoran said: "It couldn't be hidden in the first place."

"So, let them snoop."

“We just have to do our own thing.”

Zhao Aiguo said solemnly: "So, this time we can only succeed, and we must not fail."

“Otherwise, we’ll likely be laughed at.”

Wang Haoran smiled and shook his head and said, "Look, you are putting pressure on yourself again."

"I just said that we just need to be ourselves. Why should we care about what others think of us?"

"Look at the Squids, they have failed so many times. Do they care about being laughed at?"

"They will package their own failure as the failure of all mankind, and will carve flowers on the shit from all kinds of angles, saying that they won in the end."

Zhao Aiguo nodded embarrassedly and said, "Maybe there is still something wrong with my mentality."

Wang Haoran smiled and said, "You are just too nervous."

“Relax for a while!”

"Since we have done comprehensive testing and simulated many launches, and all the problems that have arisen have been solved, I think we will definitely succeed!"

The final test of the rocket is completed.

Wang Haoran, Zhao Aiguo and others all evacuated the transmission tower.

Everyone needs to retreat at least two kilometers away to ensure their own safety.

In the on-site command hall, Wang Haoran glanced at the time and said, "Let's start refueling!"

As soon as Wang Haoran gave an order, someone started adding liquid hydrogen and liquid oxygen fuel through remote control.

As mentioned earlier, since the liquid hydrogen and liquid oxygen fuel cannot be completely sealed, for safety reasons, it must be injected just before launch.

Just at this moment, a light drizzle began to fall in the night sky.

The weather in the mountains is like this. A cloud passing by may turn into a rain shower.

Therefore, weather forecasts are often impossible to be completely accurate.

Zhao Aiguo hurried over and said, "Comrade Haoran, it suddenly started raining."

"Should we suspend the launch and wait for the weather to clear?"

Wang Haoran shook his head and said, "As long as there is no violent discharge, there will be no problem."

"I think it's OK to fire."

Zhao Aiguo shook his head and said, "Okay!"

Liquid hydrogen and liquid oxygen fuel injection continues.

"Prepare for the launch countdown immediately!" Wang Haoran gave the order.

The countdown to launch has begun.

The fuel injection is still proceeding rapidly.

While the liquid hydrogen and liquid oxygen fuel are being injected, the fuel tank has actually begun to leak and release pressure continuously, so it is necessary to continuously replenish the fuel to make up for the part that has evaporated.

With only three seconds left in the ignition countdown, the remote-controlled hydrogen elimination ignition device began to spray high-temperature, high-speed metal ions to eliminate the low-temperature hydrogen before ignition to prevent hydrogen accumulation and explosion.

It is this device that ensures that the hydrogen is effectively processed before ignition.

Therefore, the ignition of this liquid hydrogen and liquid oxygen engine must be carried out strictly according to the procedures, and no mistakes are allowed.

"three!"

"two!"

"one!"

"ignition!"

Give an order!
The engine ignition started successfully!
"boom!"

Fierce flames spurted out of the engine nozzles.

The huge rocket was pushed up.

The speed was even slow at first.

It was like a montage shot in a movie. Then, as the thrust became stronger and stronger, the rocket accelerated rapidly.

In just a dozen seconds, the rocket flew out of people's sight and flew to the other side of deep space.

However, no one cheered in the command hall.

Because launching into space is actually just the first step to success.

Because the atmosphere near the earth's surface is dense and exerts great resistance on rockets, in order to leave the atmosphere as quickly as possible, a vertical upward launch is usually adopted at the beginning of the rocket launch.

Vertical launch also makes it easy to maintain stability in flight.

By the time the first stage separates, the rocket has already passed through the dense atmosphere.

Then, the second-stage rocket ignited and continued to accelerate.

When the second stage rocket separated, the rocket had already reached a high enough speed. The remaining four boosters did not ignite immediately, but continued to rise by relying on the huge inertial speed. Under the control of the ground control station, it deviated from the original vertical direction and turned to fly. Finally, it arrived at the Earth's circular transfer orbit, waiting for the opportunity to enter the geosynchronous orbit...

The whole process is still very complicated.

In the next few days, Wang Haoran stayed in the command hall almost all the time, carefully commanding every orbit change of the satellite.

Finally, after more than six days, the satellite successfully entered the geosynchronous orbit.

The rocket released two satellites into geostationary orbit.

The two satellites quickly deployed their solar panels, began self-inspection, and established contact with the ground station and began sending back signals.

At the same time, the rocket thrusters ignited further and maneuvered the remaining satellite to a position that formed a 23-degree angle with the geostationary orbit over the equator.

This is a geosynchronous orbit.

Near here, the third satellite was released and moved to the preset orbit under the command of the ground station.

The remaining part of the rocket began to slowly descend and entered the atmosphere to be destroyed.

Wang Haoran almost personally controlled the third satellite to the preset inclined synchronous orbit.

He breathed a sigh of relief at this moment.

His original plan was successful.

This is really great.

The next step is to control the satellite and prepare it for operation.

"Comrade Haoran, there shouldn't be any problem, right?" Zhao Aiguo also breathed a sigh of relief at this moment.

Wang Haoran smiled and said, "It should be considered that we have preliminarily completed our preset plan."

"But we can't say we have succeeded yet."

"Because, since we are launching a navigation satellite, we must achieve the purpose of navigation, and then it will be considered a success."

In principle, three-point positioning works.

However, no one can tell what the actual situation will be when used for satellite ground navigation.

Everyone is now crossing the river by feeling the stones.

Many comrades in China think that if this method is feasible, why didn’t Judas do it this way?
They have so many geniuses, why don’t they use this trick?

Why do scientists in Jusa conclude that 24 satellites are needed to successfully establish a network?

There are still many experts in China who lack confidence.

They think that if Jusa can't do it, we certainly can't do it either.

Zhao Aiguo swallowed his saliva and said, "If this succeeds, it will be a great initiative."

"Who knows, maybe we can actually build a global satellite navigation system before the Squids."

Wang Haoran smiled and said, "We will definitely succeed!"

"Teacher Zhao, I'm afraid you haven't thought about it before, that we can take the lead in the two major fields of electronics and computers, right?"

Zhao Aiguo chuckled and said, "You are right to criticize."

"I never thought we could be so advanced in microelectronics and computers."

"But they landed on the moon in the late 60s."

"And more than once, this is unique in the world."

"Based on this alone, they are much more advanced than us in the field of aerospace."

“We have to admit this.”

Wang Haoran smiled and said, "As for the moon landing, it's still unclear whether it's true or not."

"You've also seen that there are many voices within Squidward that question the moon landing."

"All six of their moon landings took place during the reign of Eagle King Old Ni."

"After the old monk left, they never mentioned the moon landing again."

"Personally, I have my doubts about their landing on the moon."

Zhao Aiguo scratched his head, still a little unconvinced, and said: "But when they landed on the moon, it was broadcast live around the world."

"You might have been young at that time, but I watched their live broadcast."

"When I saw the astronauts on the moon talking to old Nidi, I was really shocked."

Wang Haoran shook his head. More than a decade of publicity had made most people firmly believe that they had successfully landed on the moon.

"Do you think it's normal that the Earth-Moon communication and the images of their astronauts on the Moon can be so smooth?"

"That's 38 kilometers away. Even with today's communication technology, we can't guarantee that the live broadcast will not be interrupted."

"Squid has made too many false statements. We can't let them lead us astray."

Zhao Aiguo said: "But, in the field of communication technology, they are also unique and leading the world."

"They are such a big country, they won't lie, right?"

Wang Haoran said: "They lied too many times."

“They actually have no credibility.”

"In 1969, processors and memory were very limited, with only a few KB of memory. Under such circumstances, it was impossible to achieve smooth transmission of images and sounds between the Earth and the Moon."

"Teacher Zhao, we need to have a little common sense!"

Wang Haoran knew that it would be difficult for him to convince Zhao Aiguo.

It is difficult to change the thinking of adults.

Zhao Aiguo came from a time when Brother Long was penniless. Just a few years ago, Brother Long was still lagging behind Yusa in all aspects.

So, there are some people who just can't turn around.

They have no confidence at all.

I don't believe I can surpass the powerful squid.

Soon, the three satellites were debugged.

The communication between them and the ground station is also very smooth.

The conditions are ripe for trying satellite navigation.

Wang Haoran returned to the capital and reunited with Mr. Qian.

As soon as Mr. Qian saw Wang Haoran, he held his hand tightly and said, "Comrade Haoran, I didn't expect that everything would go so smoothly."

“We have conducted preliminary tests and there is absolutely no problem using three stars for navigation!”

Wang Haoran smiled and said, "We still need to conduct a comprehensive test."

"Comrades in the army should be allowed to give it a try."

Mr. Qian nodded and said, "It is mainly the comrades in the army who are testing it."

"Field marches, missile launches, warship navigation, and aircraft navigation are all being arranged for testing."

Wang Haoran smiled and said, "I hope it will have a good effect."

In the following days, the troops launched a series of exercises using satellite navigation terminal equipment.

All in all, the navigation network consisting of three satellites does play a very important role.

All tests were completed successfully.

Wang Haoran reported this to his leader, who was so happy that he waved his hand and said, "Such a good thing should be publicized immediately!" (End of this chapter)
