Day after day waiting.

The launch date is getting closer.

Rivi's mood also became a little anxious and apprehensive.

Sometimes standing next to the satellite launch tower, looking at the rocket that has been transferred in, and seeing the engineer holding the detection instrument and checking the status of the satellite rocket many times.

Occasionally, Levi can't help but remind the inspection engineers to check carefully and be sure to eliminate all hidden dangers.

After all, the hope of recalling the Death Fleet is all pinned on this chemical energy rocket.

In the event of a small probability event, the rocket launch fails, and the annunciator may not be damaged in the explosion or collision, but the probability of trying to get the announcer back is very small by his own efforts.

Therefore, this rocket can only succeed, not fail!

"Don't worry, it's very stable, and there will be no problems."

"Little brother, we are all old experience, believe in our technology, no problem."

"Absolutely foolproof!"

The inspection engineers said confidently, without much nervousness on their faces.

To tell the truth, if it was more than ten years ago, Xia Guo's annual space launch mission, only a few or a dozen times, every time it was launched, the whole satellite base, from the leaders to the grassroots engineers, was walking on thin ice, checking over and over again, for fear that there would be problems.

But now, Xia Guo has 40 or 50 space launch missions every year, and more than 30 times when there are few times, and the satellite base has launch missions almost every month, rocket launches are commonplace, and the psychological quality has long been tempered, and it is impossible to face a great enemy and be under pressure every time.

Moreover, Xia Guo's industrial technology level has gone up, the quality and reliability of rockets have been greatly improved, and the gradually strong technical strength has given these engineers the confidence not to be nervous.

Hear their assurances.

Levi didn't dare to urge it, for fear of urging out one flag after another, but it turned out to mess things up.

……

Soon.

On July 14th, there was no wind and it was cloudy.

Jiuquan Satellite Launch Center, satellite launch site, audience viewing area.

"Attention Fuel Department, prepare to refuel!"

Around ten o'clock in the morning, the sound of the radio set up at the top of the transmission tower sounded.

"Fuel starts filling!"

Starting from the first stage of the rocket, through two white filling tubes, the highly toxic oxidant nitrogen tetroxide (N2O4) in liquid state is pumped into the upper oxidant tank; Another filling tube pumps the equally toxic liquid burning agent metadimethylhydrazine (C2H8N2) into the lower combustion tank.

To be honest, rockets that use nitrogen tetroxide + metamethylhydrazine as a fuel combination, with small thrust and low thrust-to-weight ratio, should have been eliminated long ago and replaced by more advanced liquid oxygen kerosene rockets or hydrogen-oxygen rockets, instead of using such rockets and continuing to pollute the environment.

But this kind of rocket is cheap, even if the performance is a little worse, but the cost is at least 15% lower, and the technology is mature and reliable, it is foreseeable that this kind of rocket can fight for more than 20 years.

11.20 a.m.

The fuel filling of the thrusters of the rocket stages is completed.

Immediately, the engineers did a final inspection of the rocket and satellite status, and found no problems.

At 12 o'clock in the afternoon, the rocket was launched and entered the one-hour countdown stage.

……

Tianhai City.

In a private room at a local restaurant.

The food was already on the table, but the few people at the table did not move their chopsticks.

Instead, focus on the girl's mobile phone screen.

"Dad, Mom, you see, Brother Levi, he has a serious job, he is now an entrepreneur in the aerospace industry, and he plans to start his own aerospace company."

"Brother Livi did live broadcasts before, but also to raise entrepreneurial funds and complete the difficult original accumulation."

"Now, Brother Rivey has taken the first important step in his life, he has brought his invention of the satellite to our country's Expedition 2C rocket, which is about to take his rocket to the vast depths of space."

"It can be said that he has come to this point, and he has at least surpassed more than 99% of ordinary young people, and has done things that ordinary people dare not imagine."

"The road ahead will definitely be more difficult, but I believe that Brother Livi will rely on his smart mind to reach heights that no one dares to imagine."

Ji Yumo said.

At the same time, with adoring and admiring eyes, he looked at the handsome man standing on a dirt slope with a serious expression and holding hands.

"Is that really the case?"

Doubts flashed on Gong Xiujuan's face, she looked at the man in the video carefully, and muttered: This young man is really so good?

"That's how it should be."

Ji Xingguo next to him thought for a while and said, "Look at that satellite launch tower, how powerful can that liar do?" Wife, don't doubt our daughter's gaze, she is a genius who can be admitted to Qingbei University, and she will be easily deceived by a liar? ”

"And my daughter has been coming to Tianhai for more than half a month, except for the first day I went to the station to pick it up, and the wine disappeared without a trace on the second day, it seems that I didn't take our daughter to heart, uh~"

Noticing his daughter Ji Yumo's white eyes and bulging cheeks, Ji Xingguo hurriedly changed his statement: "It shows that this kid is career-minded and doesn't want other young people to be children's private affairs all day long, which just shows that this guy is more reliable." ”

Gong Xiujuan nodded, what her husband said made a little sense.

But thinking of the unreasonable words that the kid said on the phone, she felt that even if as her daughter said, this kid was a genius, but he was also a genius with a not very normal brain, and he was not necessarily a good match for her daughter.

"Okay, let's stop talking, the rocket will be launched in fifteen minutes, let's watch the rocket launch."

Hearing the countdown broadcast on his mobile phone, Ji Yumo was shocked and reminded his parents to be quiet, and the big scene was coming soon.

……

"Five minutes to prepare!" Commander Zero gives the command.

"The rocket launch is ready!"

"Three minutes to prepare!"

“……”

The launch window was getting closer and closer, and everyone cheered up and their eyes widened.

On the dirt slope of the viewing area.

"Your Majesty, my hands are sore, I don't want to take this phone."

Lin Guoming, who has been holding a mobile phone next to him, wants to strike, he came to watch the rocket launch, not to be a humanoid mobile phone holder, and as long as this rocket is successfully launched, it won't be long before he is the lord of Blue Mercury, but now he, the "lord of the planet", has done the chores of helping to lift the mobile phone.

"Don't put your phone!"

Ji Yumo, who heard Lin Guoming's words, hurriedly said: "There are only two minutes left, hold on for the last time!" ”

Rivi shrugged his shoulders and gave Lin Guoming a helpless expression, and then returned his attention to the satellite tower in front of him.

Lin Guoming could only grit his teeth and insist.

……

"Ready in a minute!"

"30 seconds ready!"

"Ten, Nine, Eight, Seven......"

"Six, five, four, three!" Many viewers in the audience area also shouted: "Two! One! ”

"Ignition!"

In the control hall, the commander pressed the red launch button: "Launch!" ”

Then there was a boom.

A yellow cloud of dust and dust gas emerged from the lower part of the satellite tower, enveloping the entire tower.

Then, in the middle of the billowing smoke, a white column, dragging an orange-red tail flame, rose straight into the sky.

"Buzz~"

The sound of the high-speed tail flame hitting the air is getting louder and louder.

The rocket speed is constantly increasing.

Everyone in the audience area raised their heads, the elevation angle grew, and the rocket got higher and higher.

"Huhuhu~"

The roar that could be heard in the ears became smaller and smaller, and the rocket, which had been the size of a pencil, turned into a match and then a small dot.

When the dot burrows into the clouds in the sky, only its sound can be heard, and no trace can be seen.

And the whole process lasted less than a minute.

Rivi could see the minute the rocket lifted off, didn't notice a problem, and felt that everything was normal.

But whether the rocket normally completes the separation of the multi-stage booster, whether it normally realizes the programmed turn, and whether it accurately enters the orbit...... None of this is yet known.

He waited expressionlessly for a while, not like Lin Guoming next to him, and couldn't wait to cheer in advance.

After 586 seconds.

A voice came from the radio: "The satellite was accurately put into orbit, and this launch was a complete success!" ”

"It worked! Great, we made it! ”

Lin Guoming danced, jumped and jumped excitedly.

At this time, Levi was relieved.
