The tongue of flames ejected from the bottom of the rocket, and the Long March 5 rocket flew straight into the sky.
In one second, two seconds, three seconds, the rocket was safe and sound, and no accident happened. At this moment, the sky was cloudless, and only one rocket rushed into the vast space!
In the command center, everyone's faces eased a little. During the rocket launch, the first ten seconds were crucial.
Most launch accidents occurred at this time! But now they cannot be careless. According to the plan, they have to wait until the rocket sends Tianwen-1 to the intersection orbit between Earth and Mars before they can be considered successful!
The audience in the live broadcast room could no longer wait and left messages on the barrage.
"Thank you for the Rockets you sent!"
"What a big firework!"
"Awesome, awesome!"
"Sealing!"
"It flew so fast! I can't see it!"
Du Xingyu's mobile phone shooting effect is limited, so he can't see it clearly. After more than ten seconds, the rocket nearly 60 meters high has turned into a small black stick on the screen, and it is impossible to see clearly without looking carefully.
Du Xingyu said: "Everyone, let's go to the command center now."
He hurriedly trotted 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 ten kilometers left, get ready!"
Du Xingyu explained to the audience: "Our Long March 5 Yao-4 rocket is designed with a third-stage rocket. When it is launched to 70 kilometers, the first-stage rocket body will automatically fall off. This is the most important part of rocket recycling. The most expensive engine is on the first-stage arrow body!"
There is also a large screen in the command center, with satellite photos and rocket internal camera images, which can be seen more clearly at this time.
"At the 94th second of the launch, the first-stage rocket engine was turned off, and the first-stage arrow body began to separate!" In the command center, the electronic sound of the intelligent system sounded.
In the picture, the rocket's lowest level automatically falls off and falls directly from a height of 70 kilometers!
At the same time, the second stage rocket engine began to ignite and the main body of the rocket continued to take off!
"Is the recycling platform ready?" He Jingcheng asked.
"It's ready, the recycling platform has been opened, and the sea fishing boat has been in place!" Tao Ran said seriously. Although he did not agree with Du Xingyu's plan at first, he did not slacken at all when he was working.
Du Xingyu told the audience: "Rocket recycling is dangerous. Such a large rocket body falls from a height of 70 kilometers. If the recycling fails, its power is equivalent to the launch of a missile!"
"So we build the recycling platform on the sea to avoid danger, so we can just look at the surveillance screen!"
He pointed the camera of the mobile phone at the surveillance screen of the command center. In the sky, the first-stage rocket body weighing hundreds of tons was still falling rapidly.
This is not comparable to the Starry Sky One model launched by Du Xingyu. With its gravity potential energy, if it were in the Hangda Plaza, it would have been blown up directly!
On the barrage, the audience was worried: "It's dropped so quickly?"
"Get out of the way, let me catch it!"
"Can you catch it? Haha, I'm afraid it's not being smashed!"
"As we all know, people cannot be generalized. In extreme anger, I can manually catch a rocket body weighing hundreds of tons falling from 70 kilometers!"
"Damn, I'll just be a slip shovel when I go up!"
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 maritime recycling platform according to its positioning.
As the rocket is getting closer and closer to the sea, when it reaches a certain height, the automatic ignition system is turned on again.
The extinguished rocket engine restarted, and the jet flames were suppressed by a reverse upward airflow!
The first-stage rocket body began to slowly descend in the air, and everyone's nerves became tense, and the most critical time was about to come!
Five hundred meters, three hundred meters, one hundred meters!
The first-stage rocket body is already in front of you. At this time, it is still making fine adjustments to its position! Even if it is only a few centimeters of landing gap, it may lead to the failure of this recycling!
“The recycling rack has been opened!”
"No error in positioning!"
"Start to take the place!"
The first-stage rocket body slowly landed on the marine recycling platform with extremely slow movements. When the bottom of the arrow body landed on the recycling rack and the arrow body was stable, the rocket engine was shut down for the second time.
The first-stage rocket body fell intact on the recycling rack!
"Success!" Some people shouted excitedly in the command center.
"Great! Success!" He Jingcheng looked unconcealed with joy. The rockets they fired in the past were all dropped directly into the sea after disintegrating from the air. They could catch any of them, and they could only waste them.
This is the first time in history that they have successfully recovered the first-stage rocket arrow body, a thing that costs hundreds of millions of dollars!
"It's really successful!" Tao Ran took a deep breath. His position has been shaken these days.
He was suspicious of Du Xingyu's plan, but he could not find a reason to refute him!
Now, the successful recycling of the first-level arrow body made him know that Du Xingyu’s plan was correct! This young student who had just graduated from Aviation University really created a miracle!
"Okay, okay! Come on everyone!" Cao Liang was also very excited. He said: "The Rockets are still taking off, and it is not time to celebrate the achievements yet!"
"Yes!" He Jingcheng said, "The first-level arrow body is recovered successfully. The second-level arrow body and the fairing will be separated soon. Prepare for the second recycling!"
"Yes!" Everyone was ready and started working again.
At this time, Long March 5 had already flown out of the stratosphere and entered space!
In Du Xingyu's live broadcast room, the audience was also very excited.
"The observation in Jiangnan is normal!"
"Say a thumbs up to the boss!"
"The doctor who drinks tea gives the Rockets a gift!"
"Wuhu, awesome!"
"It's too strong, the first-level arrow body has been successfully recycled! I would like to call you the hardest-core anchor in the world!"
...
"The rocket has flew out of the atmosphere and the fairing is separated!"
"The second-stage rocket engine is turned off, and the second-stage rocket body is separated!"
"The third-stage rocket engine is ignited, and the third-stage rocket is about to enter the TMI orbit (the orbit of the Earth and Mars)."
The third-stage rocket body does not need to be recovered, and it will continue to move forward with the Tianwen-1 Mars rover until it enters the TMI orbit.
"All of the matter is to be prepared to recover the fairing and the second-stage rocket body!"
In the ground command center, the second-stage rocket body and fairing were recycled again.
The roughly 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, it is easier to control.
On the offshore recycling platform, the second-stage rocket body also successfully landed on the recycling rack, without any error or crash!
"The second-stage rocket body was recovered successfully!"
“The fairing was recycled successfully!”
Chapter completed!
