The start of science and technology

The fire tongue is sprayed from the rocket, the long laund is five rocket straight to the sky.

One second, two seconds, three seconds, the rocket was safe and no unexpected occurrence. At this moment, the sky is cloudless, only one rocket rushes to the vast space!

In the command center, everyone's face has elapted some, and the rocket launch process is critical.

Most launch accidents occur at this time! But now they can't fall light, according to the plan, have been waiting for the rocket to send the day to the earth and the cross track of Mars is successful!

The audience between the live broadcasts can't wait, and they will leave a message on the barrage.

"Thank you the rocket sent by the old iron!"

"Good fireworks!"

"good job!"

"Plank!"

"Flying is so fast! I can't see it!"

Du Xingyu's mobile phone shooting effect is limited, it has been not very clear, nearly 60 meters high rockets have become a small black stick in the picture, not carefully see.

Du Xingyu said: "Everyone, now we go to the command center."

He hurriedly ran to the command center, the rocket was still boosted, but the rocket recycling has begun.

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

Du Xingyu explained to the audience: "Our Long March 5th, four rockets are the three-stage rocket design, when it is 70 kilometers, the first rocket arrow will automatically fall off. This is the most important in Rocket Recycling Part of the cost, the most expensive engine is on the first level arrow! "

There is also a big screen in the command center, which is a satellite taking photo and a rocket internal camera image, and it will be clearer.

"Lifting the 94th second, the first rocket engine offline, the first level arrow is beginning to separate!" In the command center, the electronic sound of the intelligent system sounded.

In the picture, the State of the Rocket is automatically detached from 70 kilometers!

At the same time, the second-level rocket engine starts ignition, the rocket body continues to be empty!

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

"Ready, the recycling platform is open, the sea fishing boat has also been in place!" Tao Ran said seriously, he did not agree with Du Xingyu's program at first, he did not worry.

Du Xingyu said to the audience: "Rocket recycling has certain dangers, so large rocket arrows, from 70 kilometers, if the recycling failed, the power is equivalent to the launch missile!"

"So build the recycling platform in the sea, avoid danger, we will directly watch the monitoring screen!"

He took the mobile phone camera to the monitoring screen of the command center, in the air, hundreds of tons of heavy first rocket arrows were still falling rapidly.

This is not a model of the Star No. 1 model that Du Xingyu launched, with its gravity potential, if it is the square of the original Avenue, you can blow the square directly!

On the bar, the audience is worried: "Is it so fast?"

"Let me open, let me pick up!"

"Can you pick it up? Oh, I am afraid not being smashed!"

"As we all know, people can not be in general, I can manually contact a few hundred tons of heavy rocket arrows from 70 kilometers without anger!"

"Nima, I am going up is a slippery!"

Rocket arrow is rapidly close to the ground, in the command center, they constantly adjust the power parameters of the rocket, adjust the orientation of the rocket, so it can be positioned, fall to the sea recycle platform.

It is getting closer and closer to the rocket, and when it reaches its own height, the automatic ignition system is turned on again.

The extinguished rocket engine restarted, the sprayed flame is accompanied by a reverse rising airflow to curb the trend of rocket falling!

The rocket first-level arrow is beginning to fall slowly in the air, and everyone's nerves are tight, the most critical time is coming!

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

The rocket first arrow is already in front of the eye, at this time, it is still fine-tuning! Even if it is just a few centimeter, it may also lead to this recycling!

"The recovery frame has been opened!"

"Location no error!"

"Started!"

The rocket first arrow is slowly falling on the sea recycling platform, and the rocket engine is turned off when the arrow is in the recovery frame.

The rocket level arrow, in good ends on the recycling frame!

"Success!" In the Command Center, some people excitedly called.

"Great! Success!" He Jingcheng couldn't help the lotion. In the past, the rocket they launched, they were directly dropped directly into the sea, and they can fish, and they can only waste it.

This is still the first time in history, they successfully reclaimed the rocket level arrow, this cost hundreds of millions of things!

"Really succeeded!" Taoran took a deep breath, these days, his position has been shaking.

He keeps Du Xingyu's program, but can't find a reason to refute him!

Now, the recycling of the first-class arrow is let him know that Du Xingyu's plan is true! This old is gently, I just graduated from the Avenue, I really created a miracle!

"Okay, good! Let's cheer!" Cao Liang was also excited. He said: "The rocket is still boosted, and now there is no time to celebrate!"

"Yes!" He Jingcheng said, "" The first-level arrow is successful, and the second-level arrow body and the whole coaster are separated, ready for the second recycling! "

"Yes!" Everyone was waiting, and it was in the work again.

At this time, the Long March is five, which has already fly out of the flat layer, and it is entering space!

In the live broadcast room of Du Xingyu, the audience is still excited.

"Jiangnan observation is normal!"

"For the big meal!"

"Doctor who drink tea sends a gift rocket!"

"Wuhu, cattle fork!"

"It's too strong, the first-class arrow has been successfully recycled! I would like to call you the world's hard-working agency!"

......

"The Rockets have fly out of the atmosphere, the rectifier is separated!"

"The secondary rocket engine is closed, the secondary rocket arrow is separated!"

"Three-stage rocket engine ignited, the three-level rocket will enter the TMI orbit (Earth and Mars transfer track)."

The three-stage rocket archer does not need to be recycled, and it will continue to travel with the day-honored No. 1 Mars detector until you enter the TMI track.

"All pay attention, prepare to recycle the entire flow cover and the secondary rocket arrow!"

In the ground command center, the second-level rocket arrow and the rectifier cover were started again.

The rough process is the same as before, but this time is more easier than the last time. Because the secondary rocket arrow is more easier than the first level, it is easier to control.

On the sea recycling platform, the secondary rocket arrows also succeeded on the recovery frame, there is no half an error and crash accident!

"The second-level rocket arrow is successful!"

"The rectifier is successful!"

"I announced that the rocket recycling work, successfully completed!" In the Command Center, He Jingcheng shouted!
