On the launch rack of the Chauncey Satellite Launch Center, above the white candle dragon rocket, the sky has just revealed the light of the day.

The morning star was still twinkling in the sky.

Gu Song, Jian Yushu, Guo Yue, and He Anzhi are all quietly waiting for the arrival of the scheduled launch time of the Candle Dragon rocket.

This time, I was no longer as nervous, anxious, and looking forward to it as before.

With the support of iterative thinking and sufficient funding, in fact, many links have been tested and improved and optimized several times.

In their hearts, they have a lot of certainty.

In He Anzhi's mind, he never imagined that the development of carrier rockets could be carried out in such a way and with such efficiency.

Just like he couldn't imagine before, why private companies like Flint Space and SpaceX were able to make breakthroughs in the space field so quickly.

One is to develop its own satellites and participate in the improvement of recyclable rockets, and the other is to directly develop its own launch vehicles.

The point is, both sides succeeded.

Among them, the development speed of the Candle Dragon rocket certainly has played a role in how to dispatch the methodology of system engineering.

But I'm afraid the most important thing is the quick solution given by the young man next to him on many key difficulties.

When he was full of anticipation and suggested to his superiors that he should do his best to absorb Flint Aerospace as an important partner of the Aerospace Science and Technology Group, the superior leaders were silent for a while, and then told him to digest and consolidate the existing achievements first.

Under the constant questioning of He Anzhi, who felt very incomprehensible, the superior leader told him that Gu Song wanted to participate in a more important top-secret project.

He Anzhi had no choice but to leave the office of the superior leader. He didn't know that the superior leaders also knew that Gu Song was the top scientific adviser of the project because of the inseparable relationship between the space system and the hypersonic gliding vehicle.

So now, he can only wait for the successful launch of the candle dragon rocket with peace of mind. Then, he will devote himself to the comprehensive upgrade of the Divine Arrow series of rockets.

Gu Song's heart was indeed calm.

The first test, which took place here last August, was only a preliminary demonstration for the sake of safety.

For this candle dragon rocket, he has actually poured months into it.

From the engine, to the materials, to the sensors, to the guidance system...... So many things, their design details, have been simulated in the mind.

As long as there are no problems with the installation, testing, and launch command and control teams, there will be no problems.

And these things are one of the things that China's aerospace system has always done the best.

So after the countdown was over, the Candle Dragon rocket began to take off as scheduled.

After a short period of more than two minutes, the first stage of the rocket separated.

At this time, the rocket had just flown near the Kármán line, and the follow-up orbit mission was handed over to the Chang'an Satellite Tracking and Control Center to command and dispatch, while the Chaunxi Launch Command Center nervously began to monitor the recovery of the first-stage rocket.

Unlike the last test, this time, the first-stage rocket was dropped from an altitude of nearly 100 kilometers and then recovered.

To achieve this goal, the first-stage rocket retains enough fuel and turns off the engine in advance to separate from the main body of the rocket.

Then, after adjusting the attitude, re-ignite and try to stabilize on the recovery track.

In this process, the engine will continue to ignite repeatedly to control the speed of the rocket's descent, as well as the trajectory and attitude of the rocket's descent.

In the launch command center, everyone could only watch.

Under the current technical conditions, it is basically impossible to carry out any remote control of the rocket.

The difference is thousands of miles, from the discovery of an abnormality here, to the solution through calculation, to the issuance of instructions, it has long been irreparable.

What's more, during the high-speed flight of the rocket, the plasma generated by high heat will seriously interfere with the reception and transmission of signals.

Therefore, it is possible to rely only on the navigation system installed on the rocket, which can achieve automatic control.

Real-time perception of their own attitude and position, comparison of track data in the system, according to the pre-set automatic program for correction.

Now, the data on the big screen made the people in the hall feel a little incredible.

Gu Song touched Guo Yue's shoulder and gave him a thumbs up.

Guo Yue smiled speechlessly: "If you want me to praise you, just say it." ”

Such an awesome performance is naturally due to the fact that the navigation system on the rocket is powerful to a certain extent.

In essence, everyone's biggest concern is that in the first half of the first-stage rocket recovery process, the orbit will deviate to the limit.

Now, in the second half of recycling, it is becoming more and more certain.

After all, the altitude is getting lower and lower, and the speed is decreasing.

And the state of the engine is still stable enough, and the fuel is sufficient.

Now, Skyrim can see the point of light of the first stage rocket again.

After separating from the main body, the first-stage rocket re-ignited at high altitude, and after a parabolic trajectory, the recovery trajectory was re-aligned with the Chauncee Satellite Launch Center.

The re-entry ignition lasted more than 20 seconds, slowing down the initial falling speed of the rocket at high altitudes.

Now, the third ignition of the first-stage rocket began, that is, the landing ignition.

This ignition, which will last longer, will reduce the speed of the rocket to the point where a soft landing can be achieved.

From the big screen, everyone saw that the tail of the first-stage rocket was spraying flames, and the speed of the rocket was getting slower and slower.

After the speed has dropped to a certain level, the landing bracket deploys smoothly.

In the command hall, everyone waited with bated breath, as if this would not interfere with the rocket because of their exhaled breath.

Then, the huge first-stage rocket was firmly erected on the specially vacated recovery table.

The most excited is He Anzhi.

He almost jumped to his feet to hug Gu Song.

Fortunately, after he jumped up, he remembered Gu Song's identity a little embarrassed, and put away his hand again, and the whole person had the style of an Asian dance king.

The command hall was immersed in a sea of cheers, only the commander was still forcibly calming, and the command team was ready to check the status of the first stage rocket that had been recovered.

Because according to the original plan, if the first-stage rocket is successfully recovered, the maintenance of the first-stage rocket must begin immediately.

Then, complete the hoisting of the same type of booster rocket, two-stage rocket, three-stage rocket and communication satellite as soon as possible, and try the next launch.

Gu Song remembered the limit of Musk's play, and wanted to achieve a successful launch of the rocket within 24 hours, recover it and quickly maintain the refueled, and carry the load again to successfully launch.

Think about it, what's the difference between this and a flight?

This time, the Candle Dragon Rocket is not ready to play that kind of limit.

The first-stage rocket is pulled back to the workshop and carefully inspected. After confirming that the conditions for re-launch are met, it will be assembled with other rocket components and re-launched at the right time.

Don't worry, with the first successful experience, the second time is more secure.

This side was immersed in joy, and good news came from Chang'an, the communication satellite was successfully launched into orbit.

For the launch of the satellite, the success of the recovery of the first-stage rocket does not affect whether the subsequent second-stage rocket can push the satellite into orbit.

In this regard, Huaguo's experience has been very rich and stable.

Jian Yushu couldn't wait to announce it to the public.

The first-generation Candledragon rocket, which Flint Aerospace participated in the in-depth research and development, successfully launched the first communication satellite of the "Qunxing" program into orbit, and successfully realized the recovery of the first-stage rocket.

It's going to be big news that will make waves all over the world!

Less than half a month ago, SpaceX's success seemed so insignificant in a moment!

……

Gu Song had a celebratory breakfast with them, and then set off for northern Sichuan.

On this trip, there is another task, which is to bring the old man Xie Hongxin back to Yanjing.

The Chinese New Year is approaching in a month, and the project he is responsible for is nearing completion.

Before the winter break, there will be some small construction. But he and Nie Ziqiang have been training the team for so long, and there are people under his hands who can help him keep an eye on him, and he doesn't need to stay here until the end.

Woke up too early and slept all the way.

The car arrived at the county seat of North Sichuan and drove directly to the gate of the newly built North Sichuan Middle School.

The school is very conspicuous in this ordinary small county town.

From the design style to the construction effect, it is properly eye-catching. Gu Song believes that the quality of the construction is also fully in line with the design standards.

After making a call to Xie Hongxin, Zhao Hongtao parked the car and walked to the engineering headquarters with the boss.

Xie Hongxin stood at the door of the headquarters and looked at Gu Song strangely as he walked over.

Gu Song sneered, the old man was different from his mother-in-law. The mother-in-law was worried before, just worried that Gu Song was just playing and worried about trouble in the future.

But once the relationship is determined, it is natural that the more you look at it, the more you like it.

But the old man is different, after all, he is the pearl in his hand, and he was arched by this kid.

But he also admires this kid and likes it, to some extent, it is still Party A.

What is this called?

Gu Song smiled and said, "Uncle, why are you still outside the house, come in, it's cold outside." ”

Xie Hongxin took him and Zhao Hongtao into the door, beckoned the people below to bring hot tea, and then said, "Handle the business first, go to check and check?"

Gu Song's scalp tingled when he heard this: "Uncle, if you are staring at it personally, it must be no problem." Let's ...... Let's just talk about private matters. ”

Zhao Hongtao listened to it interestingly and couldn't help pursing his mouth.

After the two of them took a cup of hot tea and drank it, Xie Hongxin sighed: "When did you have this bad idea?"

Gu Song sweated profusely, what is a bad mind? But you can't say that you like her when you are young, right? That is outrageous.

"That's it...... I just naturally think she's good. After all, you taught it!"

Xie Hongxin rolled his eyes: "Don't be blind and make sycophants." I don't think I can put any score in front of you! I can't deal with it in the future, and I'm embarrassed!"

"What's so hard about that...... You are an elder, you can play as much as you want!"

"Really?"

Gu Song nodded continuously.

"Let's go, don't drink tea, it's almost noon anyway, go drink, talk about it!"

Gu Song put down the teacup: "You are cooked here, where is it delicious?"

Xie Hongxin waved his hand: "Come with me, I'm ready for the wine." If I want you to drink well today, I have to listen to your drunken mantra!"

Gu Song is like a glutton, anyway, he has the artificial intelligence "Xie Xiaobao" in his head to suppress emotions, even if he really can't drink well, he won't talk nonsense.

When he arrived at the place, Xie Hongxin said it badly, but he didn't really want him to drink it.

It was Gu Song himself, who toasted him very seriously.

Xie Hongxin sighed and asked, "Yin Ran is still young, what are you going to do?"

Gu Song put down the wine glass and served him vegetables, and then said: "I am wholeheartedly devoted to Yinran, but now she is indeed still young and has to study." We had just made our hearts to each other, and Yin Ran needed to get to know me in another capacity. Therefore, it is not possible to directly talk about marriage now. You and your aunt believe me, just wait for her to finish college. When the time comes, I will marry her home in style. ”

Xie Hongxin glared: "You also said that you don't talk about marriage directly, you just want to marry home." ”

Gu Song gritted his teeth and didn't know how to answer.

Xie Hongxin took a bite of the dish and suppressed the wine, and then sighed: "I also talked a lot on the phone with her mother, and I was very contradictory. Xiao Song, I have known you for so many years, and you and Aunt Wang can trust you. But after all, you are now famous, your family is big, and your identity is precious, and we are all worried that Yin Ran will follow you in the future, and there will be many rights and wrongs. ”

Gu Song lowered his head and said, "I also talked to my aunt about this issue. The day has not passed that day, and I am now talking in empty words, no matter how well I say it, you are still more or less worried. But then again, even if it's not me and Yin Ran who are in love, but which other kid she is in love with, you and Auntie will be more worried, won't you? ”

"I just can't understand you anymore. I know where your roots are and what your roots are. But now it's a rocket and a robot, I know a ghost?" he said this, looked left and right, lowered his head and asked in a low voice, "I heard your aunt say, you ...... Still in the Pivot Sea?"

Gu Song nodded, and also replied in a low voice: "I am participating in two top-secret projects." ”

Xie Hongxin raised his head, looked at him blankly a few times, and then said helplessly: "Look, I don't dare to drink too much wine with you." If you get drunk and say something you shouldn't say, and I listen to something I shouldn't hear, then what's the point?

Gu Song laughed and laughed, this is really a trouble that can't be helped.

He could only smile and continue to pour wine: "There are many more good places than awkward places!"

Xie Hongxin pinched the wine glass and looked at him: "Then let's say something open between men and men now." You said that you would wait until Yin Ran finished college, then you could bear not touching her for four years? I don't believe it!"

Gu Song was embarrassed, why didn't he see him so bright before reading the file.

But that's really hard to answer.

I've endured this for so many years, and I don't know how many forest products have been fertilized with enthusiasm. Now that the two of them are in love, they are both adult men and women, and if they want to endure it for another four years, it is better to explode on the spot!

Xie Hongxin looked at his ghost appearance, gritted his teeth and drank the wine.

Gu Song used drinking to hide his embarrassment, and saw Xie Hongxin eating food silently, as if he was going to wait for him to answer.

Gu Song urgently organized words in his head.

Uncle, I won't force Yin Ran...... Eh, there is a high probability that the old man will be furious: you, you still want to force a relationship?

Uncle, I will be responsible for Yin Ran...... What if he comes back with a message: be responsible for her, just wait until the cave room is full of candles.

Uncle, since it's an open talk between men, you know it...... Could it be that the old man could only say helplessly: We must do a good job of safety measures? I am still studying, what should I do if I have a big belly?

Gu Song felt that the bright topic between men was a proposition!
