Technology's opening live broadcast to build rockets

Tongues of flame spurted out from the bottom of the rocket, and the Long March 5 rocket flew straight into the sky.

One second, two seconds, three seconds, the rocket was safe and sound, without any accidents. At this moment, the sky is cloudless, and there is only one rocket rushing into the vast space!

In the command center, everyone's expressions softened slightly. During the rocket launch, the first ten seconds were crucial.

Most launch accidents occur at this time! But they can't take it lightly now. According to the plan, success will only be considered successful when the rocket sends Tianwen-1 to the intersecting orbit of the Earth and Mars!

The viewers in the live broadcast room couldn't wait and left messages on the barrage.

"Thank you Lao Tie for the rocket!"

"What a big firework!"

"awesome!"

"Pai Noodles!"

"It's flying so fast! It's almost out of sight!"

Du Xingyu's mobile phone shooting effect was limited and he couldn't see clearly anymore. After more than ten seconds, the nearly 60-meter-high rocket turned into a small black stick on the screen. It was impossible to see clearly unless he looked carefully.

Du Xingyu said: "Everyone, let's go to the command center now."

He hurriedly jogged to the command center. The rocket was still taking off, but the rocket recovery was about to begin.

He Jingcheng stared at the screen nervously and asked: "There are still ten kilometers, be ready!"

Du Xingyu explained to the audience: "Our Long March 5 Yaosi-4 rocket this time is a three-stage rocket design. When it lifts off to 70 kilometers, the first-stage rocket body will automatically fall off. This is the most important thing in rocket recovery. part, the most expensive engine is on the first-stage rocket body!”

There is also a large screen in the command center, which shows satellite photos and rocket internal camera images, which can be seen more clearly at this time.

"94 seconds after liftoff, the first-stage rocket engine shut down and the first-stage rocket body began to separate!" The electronic sound of the intelligent system sounded in the command center.

In the picture, the lowest stage of the rocket automatically fell off and fell directly from an altitude of 70 kilometers!

At the same time, the second-stage rocket engine begins to ignite, and the main body of the rocket continues to lift off!

"Is the recycling platform ready?" He Jingcheng asked.

"Ready, the recovery platform has been opened, and the offshore fishing boats are in place!" Tao Ran said seriously. Although he did not agree with Du Xingyu's plan at first, he did not slack off at all when he was actually working.

Du Xingyu told the audience: "Rocket recovery is dangerous. If such a large rocket body falls from a height of 70 kilometers, if the recovery fails, it will be as powerful as a missile!"

"So build the recovery platform at sea to avoid danger. Let's just watch the surveillance footage!"

He pointed the camera of his mobile phone at the surveillance screen of the command center. In the sky, the first-stage rocket body weighing several hundred tons was still falling rapidly.

This is not comparable to the Xingkong-1 model launched by Du Xingyu. With its gravitational potential energy, if it were in the square of Hangzhou University, it could directly blow up the square!

On the barrage, the audience became worried: "Did it fall so fast?"

"Get out of the way, let me catch it!"

"Can you catch it? Haha, I'm afraid it won't be smashed!"

"As we all know, people cannot be generalized. When I was extremely angry, I could manually catch a rocket body weighing several hundred tons falling from 70 kilometers!"

"Nah, I'll be a sliding shovel when I go up there!"

The rocket body is rapidly approaching the ground. In the command center, they are constantly adjusting the rocket's power parameters to adjust the rocket's orientation so that it can land on the offshore recovery platform according to its positioning.

Seeing that the rocket was getting closer and closer to the sea, when it reached a certain height, the automatic ignition system was turned on again.

The extinguished rocket engine was restarted, and the jet flames, accompanied by a reverse upward airflow, curbed the rocket's downward trend!

The first stage of the rocket began to slowly descend in the air, and everyone's nerves became tense. The most critical moment was about to come!

Five hundred meters, three hundred meters, one hundred meters!

The first stage of the rocket is already in front of us, and it is still making fine adjustments to its position! Even a placement gap of just a few centimeters may lead to failure of this recycling!

"The recycling rack is open!"

“There is no error in positioning!”

"Start getting into position!"

The first-stage rocket body slowly landed on the recovery platform at sea with extremely slow movements. When the bottom of the rocket body landed on the recovery rack and the rocket body was stable, the rocket engine stalled for the second time.

The first-stage rocket body landed on the recovery rack intact!

"Successful!" Some people in the command center shouted excitedly.

"Great! It's successful!" He Jingcheng couldn't hide the joy on his face. In the past, the rockets they launched would disintegrate in the air and fall directly into the sea. They would catch what they could, and waste what they couldn't catch.

This is the first time in history that they have successfully recovered the first stage of a rocket, which cost hundreds of millions!

"It really worked!" Tao Ran took a deep breath. His position had been wavering these days.

He remained suspicious of Du Xingyu's plan, but could not find a reason to refute him!

But now, the successful recovery of the first-level rocket body let him know that Du Xingyu's plan was right! This young student who just graduated from Hangzhou University has really created a miracle!

"Okay, okay! Come on, everyone!" Cao Liang was also excited. He said, "The rocket is still taking off, and it's not time to celebrate yet!"

"Yes!" He Jingcheng said, "The first-level rocket body has been recovered successfully. The second-level rocket body and fairing will be separated soon, and we are ready for the second recovery!"

"Yes!" Everyone stood ready and got back to work again.

At this time, the Long March 5 has flown out of the stratosphere and is entering space!

In Du Xingyu's live broadcast room, the audience was also excited.

"Jiangnan observations are normal!"

“Thumbs up for the boss!”

“The tea-drinking doctor gives a gift rocket!”

"Wuhu, Niucha!"

"It's so powerful. The first-level rocket body has been recovered successfully! I would like to call you the most hardcore anchor in the world!"

…

"The rocket has left the atmosphere and the fairing has separated!"

"The second-stage rocket engine is shut down and the second-stage rocket body separates!"

"The three-stage rocket engine is ignited, and the three-stage rocket is about to enter the TMI orbit (Transfer Orbit between Earth and Mars)."

The three-stage rocket body does not need to be recovered. It will continue to move forward with the Tianwen-1 Mars probe until it enters the TMI orbit.

"Attention everyone, prepare to recover the fairing and secondary rocket body!"

In the ground command center, the recovery work of the second-stage rocket body and fairing began again.

The general process is the same as before, but this time it is easier than the last time. Because the second-stage rocket body is smaller than the first-stage rocket, it is easier to control.

On the offshore recovery platform, the secondary rocket body also successfully landed on the recovery rack without any errors or crashes!

"The secondary rocket body was recovered successfully!"

"Fairing recovery successful!"

"I declare that the rocket recovery work has been successfully completed!" He Jingcheng shouted in the command center!

Thanks for the reward of crying and falling in love with loneliness.
