Flames spewed 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 the moment, the sky is cloudless, and only one rocket rushes into the vast space!

    In the command center, people''s faces eased a little. In the process of rocket launch, the first ten seconds are very important.

    Most launch accidents happen at this time! But now they can''t take it lightly. According to the plan, they have to wait until the rocket will send tianwen-1 to the cross orbit between earth and Mars!

    The audience in the live studio couldn''t wait to leave messages on the barrage.

    "Thank you for the Rockets sent by old fellow!"

    "What big fireworks!"

    "Awesome, awesome!"

    "Arrange noodles!"

    "How fast it flies! I can''t see it!"

    Du Xingyu''s mobile phone shooting effect is limited, and he can''t see clearly. After more than ten seconds, the nearly 60 meter high rocket has turned into a small black stick in the picture, which can''t be seen clearly without careful observation.

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

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

    He Jingcheng stared nervously at the screen and asked, "there are ten kilometers left, ready!"

    Du Xingyu explained to the audience: "our long March 5 yao-4 rocket is a three-stage rocket design. When it takes off to 70km, the first stage rocket body will fall off automatically. This is the most important part of rocket recycling, and the most expensive engine is on the first stage rocket body!"

    The command center also has a large screen with 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 is shut down and the first stage rocket body begins to separate!" the electronic sound of the intelligent system sounded in the command center.

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

    At the same time, the second stage rocket engine began to ignite and the rocket body continued to take off!

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

    "Ready, the recycling platform has been opened, and the sea fishing boats have been in place!" Tao Ran said seriously. Although he didn''t agree with Du Xingyu''s plan at the beginning, he didn''t slack off when he really worked.

    Du Xingyu said to the audience: "rocket recovery is dangerous. Such a large rocket body falls from a height of 70 kilometers. If the recovery fails, the power is equivalent to launching a missile!"

    "So build the recycling platform at sea to avoid danger. Let''s look at the monitoring screen directly!"

    He aimed the camera of his mobile phone at the monitoring picture of the command center. In the sky, the first stage rocket weighing hundreds of 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 original Hangda square, it would blow up the square directly!

    On the barrage, the audience were worried: "falling so fast?"

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

    "Can you catch it? Hehe, I''m afraid it''s not smashed!"

    "As we all know, people can''t be generalized. When I am extremely angry, I can manually catch hundreds of tons of rockets falling from 70 kilometers!"

    "NIMA, I''m just a sliding shovel!"

    The rocket body is rapidly approaching the ground. In the command center, they constantly adjust the dynamic parameters of the rocket, so as to adjust the orientation of the rocket, so that it can fall on the offshore recovery platform according to the positioning.

    Seeing that the rocket is getting closer and closer to the sea, when it reaches the set height, the automatic ignition system is turned on again.

    The extinguished rocket engine is restarted, and the jet flame is accompanied by a reverse updraft to curb the falling trend of the rocket!

    The first stage rocket body began to descend slowly in the air. Everyone''s nerves were tense. The most critical time was coming!

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

    The first stage rocket body is close at hand. At this time, it is still making position fine-tuning! Even if it is only a few centimeters, it may lead to the failure of this recycling!

    "The recycling rack has been opened!"

    "No error in positioning!"

    "Start landing!"

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

    The first stage of the rocket landed on the recovery rack intact!

    "It''s done!" some people shouted excitedly in the command center.

    "Great! Success!" he Jingcheng couldn''t hide his joy. The Rockets they launched in the past fell directly into the sea after disintegrating in the air. If they could catch anything, they could only waste it.

    For the first time in history, they successfully recovered the first stage of the rocket, which cost hundreds of millions!

    "Really succeeded!" Tao Ran took a deep breath. These days, his position has been shaking.

    He doubts Du Xingyu''s plan, but he can''t find a reason to refute him!

    Now, the successful recovery of the first-class arrow let him know that Du Xingyu''s plan is right! This young student who just graduated from aviation university has really created a miracle!

    "OK, OK! Let''s go!" Cao Liang was also excited. He said, "the rocket is still taking off. It''s not time to celebrate!"

    "Yes!" he Jingcheng said, "the first-class arrow body is recovered successfully. Immediately, the second-class arrow body and fairing will be separated and ready for the second recovery!"

    "Yes!" the people were ready and threw themselves into their work again.

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

    In Du Xingyu''s live studio, the audience were also excited.

    "Jiangnan observation is normal!"

    "Praise the big man!"

    "The doctor who drinks tea gives a gift rocket!"

    "Wuhu, ox fork!"

    "Too strong, the first-class arrow body has been recovered successfully! I would like to call you the world''s hardest core anchor!"

    ……

    "The rocket has flown out of the atmosphere and the fairing has separated!"

    "The two-stage rocket engine is turned off and the two-stage rocket body is separated!"

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

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

    "All attention, prepare to recover the fairing and two-stage rocket body!"

    In the ground command center, the recovery 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 two-stage rocket body is smaller than the first stage, it is easier to control.

    On the offshore recovery platform, the two-stage rocket body also successfully landed on the recovery rack, without any error or crash!

    "Successful recovery of two-stage rocket body!"

    "Fairing recovered successfully!"

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