　　At 18:00 on May 5, 2020, another Chinese new model rocket, the Long March 5B, was fired into the air, and the new-generation manned spacecraft test ship was accurately sent into the predetermined orbit. The first launch of the Long March 5B was a complete success.

　　At the moment when the separation of ships and arrows was completed accurately, the center of the test launch command hall, Hu Xudong, the commander of the launch mission of this launch, took off his glasses and wiped tears from his eyes. After a bit of anticipation of the carnival after success, more is the composure of completing the answer sheet.

　　"No. 01" refers to the "big steward" of the rocket launch mission. 15 minutes before the launch, the headquarters authorized "No. 01", and various data of the rocket and satellite were collected here, waiting for "01" to be analyzed Make the appropriate instructions. Hu Xudong, who once served as the commander of the first flight mission of the Beidou-2, Fengyun-2 and Changzheng-5 launch vehicle "01", has experienced such scenes countless times.

Hu Xudong, a graduate of Southeast University, has served as the "01" commander for multiple rocket launch missions, and is known as the youngest "01" commander. Correspondent for pictures

　　Three years ago, the same command hall, the same equipment, similar scenes, similar actions, but completely different moods.

　　On July 2, 2017, sitting in this seat, Hu Xudong watched the flight curve of the Long March 5 Yao-2 rocket abnormally, constantly shaking his head and sighing, couldn't help but fall off.

　　1038 days later, at the moment when the Long March 5B accurately completed the separation of the ship and arrows, looking at the big screen, Hu Xudong thought more about the scenes in the past three years.

　　After the failure of Yaozheng No. 2 on the Long March, Hu Xudong and the entire team carried out the task review day and night, searching for various hidden dangers and analyzing the reasons for the loss ...

　　Especially when entering the mission preparation period of Changzheng No. 5 B, equipment recovery and mission preparation are in parallel, gas supply equipment inspection and maintenance, filling pipeline blowout replacement, launch platform maintenance and transformation ... Almost every job he is on site, if Hu Xudong always feels "worried, and can't sleep well" when any job is left.

　　Compared with the picture of the test launch command center 3 years ago, Hu Xudong, who has just turned 40 this year, obviously has a lot of white hair. In order to pursue the 100% success of the first flight of the Long March 5B, he always asked himself to take 200% of the effort.

　　Long March Five B is an extension of Long March Five. There are great similarities, but there are also great differences.

　　"There are changes in hardware and software. It is a problem to test new rockets with the old methods." Hu Xudong introduced that the biggest difficulty of the Long March 5B test is to sort out the test operation adjustments brought about by the changes in technical status in advance.

　　Because of this year ’s epidemic, more than one-third of the staff in the post could not be invested in the Long March 5B mission, which also included several sub-system commanders. The shortage of manpower locked the always-smiling "big butler" brow.

　　After selecting a group of new commanders to fill the vacancies, Hu Xudong also organized the decomposition process of each system to further refine the test time, and each test requirement was accurate to 10 minutes.

　　Despite the shortage of personnel, the test launch quality standards have never been lowered. "There is a 'sky rule' for aerospace launches: progress is subject to quality, and progress is subject to safety. Ning Ken would work overtime for several hours a day, and it must not affect the quality because of the small number of people."

　　During the test of the first-level engine, Zhao Feng, the post operator, found that the sound was abnormal. Hu Xudong insisted that the experiment should be repeated with the unloaded equipment. The result showed that there was an abnormality in a component of the engine, and finally made a decision to replace the component at the launch site. A hidden danger in the launch mission of Long March 5B.

　　"Although the success rate of the first flight mission of a new type of rocket in the world is only 51%, as long as the rocket enters the launch site, we must strive to ensure 100% success." This is also the "iron rule" of Hu Xudong's work.

　　"The youngest '01' commander" "Net red is the most beautiful '01' commander" ...... Hu Xudong has many titles, but his favorite is "the dream-chaser of the new era."

　　After graduating from Southeast University, Hu Xudong chose to pursue his dream of aerospace heroes and resolutely came to the Xichang Satellite Launch Center under difficult conditions. With rich knowledge of the principles of the Long March 3A series rockets, excellent organization and command capabilities, and troubleshooting capabilities, it quickly grew into the youngest "01" commander.

　　At this time, Hu Xudong faced a dilemma: whether to stay in Xichang for better development, or go to the island to pursue the dream of a big rocket. The new launch site means new opportunities, but it is also full of variables. Hu Xudong did not hesitate and boarded the train south. Tracking equipment installation during the day, leaving every inch of the fuel pipeline with his footprints; studying drawings at night, the skin on his body was reddened by mosquito bites every day, so he spent his sleepless days for his dream night.

　　Now, hearing the good news of the successful launch of Rocket Long March 5B, Hu Xudong ’s teachers and alumni are extremely proud and excited.

　　“It ’s my luck to be Hu Xudong ’s teacher. After graduating for more than 10 years, he was obscured by his outstanding academic achievements and had little contact with the outside world. For a long time, his classmates missed him, but no one knew where he was? What kind of work? How is your health? "Jiang Huijuan, a retired teacher of the School of Energy and Environment at Southeast University and the class leader of Hu Xudong University, watched the launch site on TV and blessed the former lovers." For so many years, Xudong has worked hard. As a teacher, I you are proud!."

　　"The successful launch of the" Fat Five "is the pride of the Chinese people, and what makes me more proud is that the commander of the rocket launch mission" 01 "is our Hu Xudong principal of the School of Energy and Environment of Southeast University. I still remember the 16th year of Hu Xudong. Going back to my alma mater, I said, "Don't worry about earth and earth, be a celebrity," let me appreciate the style of Chinese astronauts for the first time. Thank you, Xu Xudong, and all Chinese astronauts for their outstanding contributions to the motherland, and pay tribute to you. " As a student of Hu Xudong, Wu Di, a 2016 undergraduate from the School of Energy and Environment at Southeast University, said excitedly, "I will study hard with my seniors as an example, build up my skills, strengthen my ideals and beliefs, and strive for a better tomorrow for my country. Contribute power. "(End)
