The live broadcast screen slowly shifted to Ye Fan's body.

At this time, Ye Fan was in a building three kilometers away from the launch center, and there were a large number of staff members busy around him.

This time the rocket was launched, Ye Fan was actually confident.

After all, with Datang Technology's scientific and technological reserves, making this kind of thing is like playing, if Datang Heavy Industry's dozens of industrial machine tools are turned on, a rocket can be produced in three days.

Ye Fan in the picture, different from the calm and casual in his usual days, he was not smiling at this time, and was staring closely at the live broadcast of the rocket on the big screen in front of him.

"The rocket preparation procedure has been completed, the launch time has been reached, please indicate." A female staff member put down the walkie-talkie in her hand and spoke.

"Very good, the countdown to the rocket launch begins, ten seconds."

Ye Fan looked at the dense buttons on the console, and his eyes fell on the red button in the center.

The red button also has a palm-sized transparent glass cover on it, which is a physical anti-mistouch device to avoid accidentally touching it and causing unnecessary trouble.

I saw Ye Fan gently lift the lid and put his hand on the red button.

"Now start the countdown, ten, nine, eight, seven, six, five, four, three, two, one!"

"Ignition!"

Ye Fan pressed heavily on the red button, and with a crisp sound, the rocket carrying Ye Fan's hope was officially launched.

At this time, the large rocket launch tower had been opened, and the tail end of the "Qinglong" rocket was slowly emerging with a light blue light.

This is the light of the ion engine starting at power, and in less than a second, the rocket, which was still stationed, began to slowly move towards the sky.

Thanks to the ion engine, the distance from the ground to the atmosphere is 30,000 meters, and the rocket engine does not need to work.

The ion engine will accelerate the rocket to a very high speed, and then let the rocket engine take over, which is equivalent to raising the launch site directly to an altitude of 30,000 meters.

However, in the eyes of outsiders, this rocket of Datang Technology is simply incredible.

Because if it is a fuel rocket, the light emitted by the start of the rocket engine is generally an orange-red flame, and it is very spectacular.

And this was the first time they had seen a blue rocket tail.

In less than three seconds, the rocket left the rocket launch tower directly, and then began to accelerate continuously, directly rushing to a height of several hundred meters.

The countless onlookers at the scene suddenly waved their hands at the rocket frantically, warmly celebrating the successful launch of Datang Technology's rocket this time.

You must know that the most difficult thing about rocket launch is the ignition stage, if the preparation is not done well, then in the ignition stage, it is easy to have problems.

For example, some rocket launch accidents, most of them explode when they stay in the rocket ignition stage, which is caused by the negligence of the staff during the inspection stage.

After the rocket lifts off, it begins to make turns according to the program, and the rocket begins to make turns according to the program.

The launch of the rocket will actually "fly diagonally" after rising to a certain height, rather than maintaining a vertical attitude.

Because the earth has a rotation, if it flies diagonally, it can save a lot of fuel and can send heavier things into space.

In just half a minute, the rocket has already flown directly to an altitude of more than 30,000 meters.

At this point, the entire shell of the rocket has turned red, because of the temperature rise caused by the violent friction with the air caused by the huge acceleration.

However, this is only a spike in the temperature of the shell, and the rocket has a double shell.

The materials used in the first shell are not the same as those used in the second shell, and the first shell completely dissolves when it rises to 60 kilometers into the atmosphere.

At this time, the second-stage rocket engine has already started working, and the violent friction with the air will make the temperature even higher.

The air at this altitude is already very thin, and although there is still a distance of air friction, the situation is much better than that of the air-rich surface.

When the rocket lifts off to the atmosphere for 90 kilometers, it can be regarded as having left the gravitational circle of the earth, and it is only one foot away from entering space.

And the one who bears this "kick in the door" role is the first-stage engine of the last stage of the rocket launch.

"Whoosh!"

As the last stage of the rocket was abandoned and separated, the first stage of the rocket engine began to start at power, and flew into space with the tip of the last stage of the rocket.

In another three minutes, the rocket passed through the last black barrier and rushed directly to the Earth's low-earth orbit.

Low Earth orbit is generally some small satellites, or some orbits floating on space junk.

Because the distance between low earth orbit and the earth is very close to that of high earth orbit, it is necessary to adjust the orbit in real time, otherwise it will fall to the earth like space junk and burn up like space junk.

By the time the cargo capsule reached low-earth orbit, the mission had been completed, and its three communications satellites were lightly sprinkled out like seeds.

The electromagnetic propulsion engines carried on the three communication satellites are running at half power, and their electromagnetic propulsion engines are enough to maintain the orbit change needs of the communication satellites for more than 10 years.

Although communication satellites are said to be a cover for people's ears, they are also things that can be used with real money, and they can't be left alone like space junk.

At the same time, the cargo compartment at the other end has begun to crack, and there is a part of a mining spacecraft inside, which has activated optical stealth and electromagnetic wave shielding functions, and is flying towards the far side of the moon under the slow acceleration of the electromagnetically propelled engine.

This time the rocket launch was a complete success, which was what Ye Fan expected, if it could fail with Datang Technology's technical reserves, it would really be a big laugh.

"Look, now Datang Technology has successfully completed the task of rocket launch, it can be said that they are the first private enterprise in China that can launch rockets, let us applaud Datang Technology!"

"From Datang Technology, we see the shadow of Musk's company, once Musk launched a plan to launch rockets to seize 2000+ space orbit positions,

To be honest, the position of the space orbit still belongs to the first-come, first-served model, and I look forward to Datang Technology being able to achieve complete success in the future and make its own outstanding contributions to China's aerospace industry!! ”
