Du Xingyu started the live broadcast at this time, and the notified audience entered the live broadcast room.

    "Hello, everyone. You should see that our rocket launch preparations have been completed. In three minutes, we will launch on time."

    "Here, we went to the farmers'' market to buy a live rooster, weighing 2.1kg. We also designed a small space capsule for it. At that time, the rocket will send the chicken to an altitude of 20 kilometers!"

    "This rocket, I named it star one, which means our first step towards the stars!"

    In the live studio, the audience laughed.

    "Observe three minutes of silence for this chicken. Soon it will become a high-altitude roast chicken!"

    "I hope the launch succeeds!"

    "What about my little sister? I came to see my little sister!"

    "Hurry up, I can''t wait!"

    "Sit and wait for the monkey to go to heaven!"

    At this time, the number of viewers in the live studio showed that there were 1000 people.

    Du Xingyu explained a few words and asked Xu Lianqiu to appear on the camera. The audience in the live studio immediately increased by 1000, and some people gave small gifts directly.

    "There are only 30 seconds left, everybody!" Du Xingyu and others sat in the distance. They connected the rocket control system through a laptop computer.

    "Start counting down!" Du Xingyu looked at the time and counted down: "ten, nine, eight, seven..."

    The students were unconsciously nervous. Although they didn''t make the rocket, they had a strong sense of participation as classmates and audience.

    "Three, two, one! Fire!" the ignition program starts automatically, and the igniter inside the rocket responds accordingly.

    The hot flame ejected from the bottom of the rocket, generating a strong air flow, pushing the rocket to the sky.

    During this period, accompanied by the roaring noise, the rocket took off!

    "Fly!" they exclaimed, looking at the sky in surprise.

    They could see that the star one was steadily taking off towards the clouds. The rooster in the space capsule was crowing in horror.

    "It really took off!" the audience were stunned in the live studio.

    Many people watch the live broadcast with a fun attitude and don''t think the rocket made by Du Xingyu can take off.

    But now, the rocket actually rose to the sky. Their hearts were no less shocked than the audience.

    Barrage: "66666666!"

    "Cow beer! Cow beer! Cow beer!"

    "A congratulatory message from Jiangnan Vocational College of science and technology!"

    "The anchor is too hung up! The rocket made has really taken off!"

    "This is the hardest anchor I''ve ever seen! Focus decisively!"

    "Lying in the trough, it''s true!" Zong Ming, who watched the live broadcast, was eating potato chips. This scene made him stop and stare at the computer screen.

    "Take off, it seems that the height has been thousands of meters!" Lin Guangyan looked up, but in more than ten seconds, there was only one small black spot left on XingKong No. 1.

    "No! No!" Zhou Bin said with an excited face, "students who have achieved this level are definitely the first in the history of Hangda. It is estimated that we teachers and professors dare not say we can do it!"

    "Let''s go and have a look. I want to know the specific process!" he took Lin Guangyan to Du Xingyu to see the computer monitoring screen.

    "At present, the lift off altitude has reached 8.5km, and the rocket is in good condition. The driver may be a little frightened, but his life is in good condition." Du Yuxing''s notebook shows the data and pictures of the rocket''s internal monitoring system.

    "Our rocket really took off!" until now, Wang Wei and others still can''t believe it.

    To be honest, they only thought Du Xingyu was whimsical at first. Help is purely because of the relationship between classmates and roommates. They don''t dare to think about it!

    "Great!" Xu Lianqiu''s pretty face was flushed and extremely beautiful, which was caused by excitement.

    Du Xingyu himself was a little excited. He carried out such a scientific research experiment for the first time.

    He took a deep breath to restrain his excitement and said, "it''s not over yet. It''s the hardest place to recycle later!"

    There have long been many experiences and precedents in rocket launch technology, but the whole world is in the exploratory stage of rocket recovery technology.

    If their experiment is successful, the significance of this rocket launch will not be limited to a student graduation project, but will affect the whole aerospace industry!

    The rocket continued to rise, breaking through the clouds, until the rising fuel burned out, and the lift off distance reached 26.3 kilometers. At this time, it had entered the stratosphere.

    Then the rising thrusters stopped working and the rocket began to fall. This is a particularly critical step. If you fall at an altitude of 26 kilometers, the hard metal structure will break!

    Du Xingyu made two preparations, parachute and thruster section II fuel.

    "Everyone, stay away. If you hit you, you''ll die!" Wang Wei shouted with a horn and asked the students to step back.

    The students quickly evacuated, and the Rockets were still falling rapidly in the sky.

    "Your recovery is still fixed?" Zhou Bin found that Du Xingyu was adjusting the destination of the rocket by adjusting the micro air jet device.

    "Yes, I designed a fixed-point recovery system, which will fall within a diameter of 10 meters around the landing point," Du Xingyu said.

    "Fixed point recycling!" Zhou Bin''s heart was shocked. NASA has studied this technology for more than ten years! So far, there is no breakthrough! Can he do it as a student?

    The rocket is constantly adjusting its direction, and its distance from the ground is getting closer and closer. If such a rocket falls on the ground and is unprepared to directly hit the square ground, it is equivalent to a small bomb!

    "Here we are!" Du Xingyu kept staring at the distance sensor. When the calculated landing distance was reached, the propeller started for the second time, using the second fuel reserve to generate reverse propulsion force to offset the gravitational potential energy of the falling rocket.

    The falling speed of the rocket began to slow down. Du Xingyu pressed the button, and the space capsule containing the rooster was ejected. The parachute opened at the same time, and the space capsule began to fall slowly.

    The body of the rocket continues to slow down and land towards the landing point.

    "It''s going to fall!" everyone was nervous. In the sky, it was clear that the rocket was falling. Its tail flame is still burning!

    "Five hundred meters!"

    "Three hundred meters!"

    "One hundred meters!"

    "Twenty meters!" the star one rocket stopped at a distance of twenty meters from the ground and didn''t hit it directly.

    "Land!" Du Xingyu shouted. The rocket landed slowly and smoothly at the set landing point. Except that the coating of the arrow body was lost due to atmospheric friction, all other parts were intact.

    "Success!" Du Xingyu first stood up and shouted excitedly.

    "Landing succeeded!" Wang Wei jumped up excitedly.

    "Did we launch successfully? Did we recycle the rocket? Wang Wei, take a picture of me. Am I dreaming?" Zhao Qingquan was a little confused.

    "It''s true to have a fart dream!" Lu Liang exclaimed. "I admit that my calculation is wrong. I once estimated that the success rate of the rocket launch was zero percent, but now it actually launched successfully and landed perfectly - Du Xingyu, you are really God!"

    "My God, Du Xingyu! You did it!" Xu Lianqiu hugged Du Xingyu excitedly and shouted excitedly.
