Huaxia, South, Changhai space launch site.

    This is a coastal launch base and one of the few low latitude launch sites in the world. Geosynchronous orbit satellites, high-quality polar orbit satellites, large tonnage space stations and deep space probes are launched here.

    The "tianwen-1" Mars probe to be launched this time also chose Changhai space launch site.

    NASA colleagues have long been ready. On the offshore launch platform, the "tianwen-1" Mars probe has been loaded on the Long March 5 remote-4 (b) carrier rocket.

    This rocket is different from the past. It has been transformed and equipped with the rocket recovery system designed by Du Xingyu, so it also attracts more attention.

    "Are you sure?" Cao Liang, the leader of the space administration, stood outside the launch site, looked at the 56.97 meter long rocket and asked he Jingcheng.

    "The rocket recovery and simulation test results are successful. The success rate of real launch should be more than 50 percent," he Jingcheng said.

    "50%?" Cao Liang frowned slightly and said, "why, you can give me a bottom line. The Mars exploration mission Bureau has been preparing for nine years! The last Mars probe was launched by a Russian rocket in 11 years... We have to fight for breath!"

    "I can''t guarantee anything else, but there will be no problem in the launch process!" he Jingcheng vowed. "Our rocket can definitely put tianwen-1 into orbit. If it can be recovered successfully, it will be an unexpected joy!"

    "It''s more than a surprise!" said another middle-aged man with thin hair, "then you will be world-famous and set a new record in the history of aerospace!"

    He is the head of the Mars probe design team, Mo Shen. This mission is related to his nine-year efforts and his team!

    Mo Shen said: "at present, only the National Space Administration and space exploration companies in the United States have mastered the basic rocket recovery technology in the world, but they still can''t reuse the recovered rocket engines."

    "If we can go ahead, we will not only look at the world with admiration, but also create a 10 billion aerospace market for us!"

    At present, the world, even the United States with the most developed aerospace technology, has to treat expensive rockets as disposable supplies. If China can master mature rocket recovery technology and reuse rockets, I''m afraid countries all over the world will have to come to the door and pay for help in launching satellites and spacecraft.

    The 100 billion aerospace market is no joke!

    "Look, we can''t expect too much. After all, we don''t have much experience in this field. I''m ready to fail a hundred times," he Jingcheng said.

    "Today''s first task is to send tianwen-1 to the earth fire track!" Cao Liang said with his back to his hands, "get ready. Don''t let reporters from other countries see jokes!"

    Today''s launch is an open launch. Journalists from various places and countries have long come to the launch site to watch and interview.

    The rocket will be launched at 12:41 noon. Du Xingyu came to the launch site at 6 a.m. and tested the rocket status with his colleagues for the last time. Everything was normal.

    Next, they all have to wait patiently in the command center until launch.

    After soliciting the consent of his superiors, Du Xingyu was allowed to broadcast the launch process live on his mobile phone.

    12: At 20, Du Xingyu opened the live broadcast.

    Tens of thousands of people immediately poured into his live studio to watch the rocket launch.

    "It''s on, it''s on!"

    "Where''s the rocket? Let me see the rocket?"

    "The anchor finally started broadcasting. I''ve been waiting for two months!"

    "Where''s your rocket?"

    The audience kept firing bullets. Du Xingyu stood outside the auditorium of the launch site, with the camera facing the launch pad and said, "look, that''s the Long March 5 remote 4 carrier rocket we''re going to launch this time. Tianwen 1 Mars probe has been installed in the rocket."

    "In twenty minutes, the rocket will fire on time."

    The audience looked at the launch site and marveled.

    "6666! Live broadcast of rocket launch!"

    "Last time it was a model. This time it''s real!"

    "Did the anchor participate in rocket design?"

    "Certainly not. The anchor has only been in the space agency for two months. How can he be so fast?"

    Du Xingyu explained: "everybody, the Mars probe and rocket are designed and manufactured by NASA''s predecessors. What I participated in was to install a recycling system on this rocket."

    "You should know that rocket recycling is a worldwide problem... Before, there were many voices on the Internet questioning me, saying that the star 1 rocket I made was just a toy!"

    "Look, today''s rocket has a total length of 56.97 meters, a wingspan of 17.3 meters and a takeoff thrust of 10524 × 1000 newtons, 867 tons of rocket body alone! "

    "Today I will recycle this rocket. The first stage arrow body, the second stage arrow body and the fairing are all recycled to ensure that they can be reused."

    Du Xingyu said, many people don''t understand, and asked on the bullet screen, "what''s the use of this?"

    "If it''s big, it''s technological progress, making great progress in aerospace technology. If it''s small, this time, if it''s successful, it will save the country at least one billion!" Du Xingyu said casually.

    When he finished, the barrage was immediately painted with "6666!"

    "Big brother ox fork!"

    "Save one billion at a time and ten billion at a time. Our country launches dozens of rockets every year, saving tens of billions a year?"

    "Blow, you can blow hard. There are a group of mentally retarded people who believe that this guy can do it. I eat the keyboard!" some people also start blowing when they disagree!

    "Tut Tut, can''t you, can''t you? No one really believes this liar? Other aerospace experts have publicly attacked him online!"

    "I just want to ask, if you fail, how many years will the anchor be sentenced to?"

    Du Xingyu looked at the barrage and said, "the one called ''early egg'', you said you should eat the keyboard if the launch is successful? Don''t advise later."

    Morning egg: "hehe, afraid of you? Who counsels who grandson!"

    Audience: "I want to cheat food and drink again!"

    "Remember, wait a minute, Aite him!"

    Du Xingyu is broadcasting live here. Reporters and photographers have set up equipment and started shooting.

    "Du Xingyu!" a crisp voice called his name. Du Xingyu looked back and saw that it was the last TV reporter, Lu Jiajia.

    It was hot in the south. She wore a cool white T-shirt and shorts, revealing healthy wheat skin and slim figure.

    "Sister Jiajia, are you there too?" Du Xingyu asked.

    "I''m a reporter from the science and technology channel. I''m basically going to cover the news of aerospace." Lu Jiajia''s eyes narrowed slightly when she smiled, like a crescent moon.

    "It''s great to see the news that you entered the space agency!" Lu Jiajia praised. Seeing his mobile phone lens, he said curiously, "are you broadcasting live?"

    "Yes." in Du Xingyu''s live studio, many viewers have been painting the bullet screen of "beautiful little sister".

    "I have something else to talk about later." Lu Jiajia was called away by his colleagues, and Du Xingyu continued to broadcast live.

    At 12:40 noon, only one minute before the rocket launch, he Jingcheng, Mo Shen, Tao Ran, Liu Yuan and others were already nervous in the command center.

    In Du Xingyu''s live studio, there are already more than 100000 viewers waiting for the ignition countdown.

    He Jingcheng''s voice came from the horn, "ten, nine, eight... Three, two, one!"

    "Fire!"
