On the way to explore the vast starry sky, young astronauts practice their ideals with actions.
At the Xichang Satellite Launch Center, there is such a slogan - "Screws are connected to the aerospace industry, and small buttons maintain national dignity." ”
China has a young team of astronauts, and they are the real hope. On the way to explore the vast starry sky, this group of young people with the universe in mind are practicing their ideals with actions.
"Living drawings" in Xinchen
In 2011, 20-year-old Yu Xinchen graduated from Tsinghua University majoring in engineering mechanics and aerospace engineering. When many students chose to go to graduate school or go abroad, he gave up the opportunity to study graduate school and plunged into the Xichang launch site for 10 years.
Yu Xinchen's aerospace road began with the elevator operator - the daily job is to pick up and drop people on the tower to the corresponding floors in the elevator. "Whether it is a doctorate or a master's degree, a graduate from Tsinghua University or Peking University, there will be this stage. I must polish the relatively high spirit when I first graduated. ”
In 2012, Yu Xinchen became an ordinary operator in the rocket's conventional power system. It took only a year for him to fill the job and began to serve as the system's rocket professional.
Yu Xinchen's learning ability is obvious to all, so when the rocket cryogenic power system needs to operate a hand, he becomes the right person. It's a high-intensity job. The cryogenic power system involves the filling of liquid hydrogen liquid oxygen low temperature propellant, the temperature of the low temperature propellant is extremely low, flammable and explosive, and the test process is complicated and cumbersome. This requires the operator to maintain a high degree of concentration 8 hours before launch, and there can be no flaws.
In order to quickly find possible leaks, Yu Xinchen gradually developed a skill - "listening to sound detection leaks". This skill has allowed him to successfully troubleshoot many times. At the same time, he often checked the status of each joint against the drawings, which allowed him to say the position and details of the joints with his eyes closed, so he was called "living drawings" by his colleagues.
The commander of the rocket cryogenic power system often deals with flammable, explosive, and leaky fuels and is called the "most dangerous post.". Yu Xinchen said: "The biggest challenge is not these, but every work before the launch, if a certain work goes wrong, it is likely to lead to the postponement or cancellation of the launch." In addition, there is also how to quickly and accurately locate and deal with it scientifically in a timely manner in the face of unexpected situations to ensure the smooth progress of the launch. ”
Since his work, he has participated in and successfully completed more than 80 space launch missions, successfully launched more than 110 satellites, eliminated major faults affecting the success or failure of launches for many times, and played an "escorting" role in each mission.
Why didn't you stay in Beijing in the first place? Yu Xinchen's answer was: "The state and the school have trained me to study aerospace for 4 years, and I still hope to apply the knowledge I have learned to the corresponding fields." ”
Yu Xinchen always remembers, "The dean of the School of Aeronautics and Astronautics at that time was Academician Wang Yongzhi, who was the first chief designer of manned spaceflight in China. When talking with us before graduation, Academician Wang mentioned the development plan of the national space industry, the future has lunar exploration, deep space exploration, etc., we have a lot of great undertakings to do and achieve."
In 2011, at the age of 20, Yu Xinchen graduated from Tsinghua University majoring in engineering mechanics and aerospace engineering. He plunged into the Xichang launch site and stayed for 10 years.
In 2019, Bao Shuo (former middle) served as the chief dispatcher for the first time and served as the commander of "Chang'e 4".
"Iron Man" Bao Shuo
In the early morning of May 15, 2021, "Tianwen-1" landed on Mars smoothly.
At that moment, a female dispatcher issued one instruction after another with a steady speed of speech, accurately and firmly. This calm woman is Bao Shuo, 29, the 29-year-old beijing chief dispatcher of "Tianwen-1", who is also the first female chief dispatcher of the Beijing Aerospace Flight Control Center.
In 1992, Bao Shuo was born into an ordinary family in Fengtai, Beijing. His father was a taxi driver and his mother was a Shougang worker. In her childhood, whenever others asked what Bao Shuo's ideal was, she would answer: "Become an astronaut." ”
In 2010, at the age of 18, Bao Shuo was admitted to Beijing Institute of Technology, majoring in information countermeasure technology.
Bao Shuo recalled: "The most impressive thing is Academician Wang Yue's class, the old man's patriotism and desire to serve the country deeply affected me, guiding me to make unremitting efforts for the research direction I love. ”
After graduation, Bao Shuo entered the aerospace system work.
After 5 years of hard work, she achieved excellent results in terms of professional, psychological and physical qualities. Physically, it is necessary to practice until continuous work can still be energetic and concentrated; psychologically, in the face of high intensity, maintain a stable state of mind to deal with emergencies.
In 2019, Bao Shuo served as the chief dispatcher for the first time and served as the commander of "Chang'e 4".
A year later, in 2020, the 28-year-old Bao Shuo was appointed chief dispatcher.
The training was arduous: he could only sleep 3 hours a day, in order to insist on 30 hours without rest when commanding; and in order to maintain physical fitness, Bao Shuo insisted on running at 5 o'clock in the morning every morning. In order to change her doll tone, she secretly practiced after work, practicing until it changed from a doll sound to a sonorous and powerful voice.
In the early morning of November 24, 2020, the "Chang'e 5" probe soared into the sky, and Bao Shuo used a sonorous and powerful dispatch password to start the 25-day trip of "Chang'e 5".
In this way, during the mission, Bao Shuo did not rest for more than 20 consecutive hours, and under the code name of "Beijing", he intensively issued thousands of calm and powerful instructions.
Colleagues commented on Bao Shuo: "As long as she enters the flight control hall, she is like a changed person, becoming An Iron Man, and can not drink water, eat, or rest for a long time." ”
That string was always stretched in Bao Shuo's heart, and she did not dare to slack off in the slightest, because "there has been no girl in this post for 40 years, and she must make a good start."
Zhou Chengyu, known as the "eldest sister"
"Rocket Girl" Zhou Chengyu
Young, but known as "big sister"; small in stature, but can support the dream of spaceflight.
Zhou Chengyu was called the real "rocket girl" by netizens, and was also called "big sister" by colleagues. In fact, this "big sister" is after 95, only 1.58 meters tall, but her work ability is very strong, which makes her competent enough to be the commander of the connector system of the "Chang'e 5" lunar exploration mission, and become the first female commander in the history of Wenchang Space Launch Site.
Zhou Chengyu is from Guizhou. In the work, the "big sister" can bear hardships, is willing to endure hardships, and is a famous hard role.
The title of "Big Sister" is not an empty word, but is obtained with practical actions. In a 3-kilometer test, the seemingly petite Zhou Chengyu defeated more than half of his male compatriots. The move of "big sister" broke the stereotype of women by colleagues in the unit.
In the work, the tenacity, not afraid of hardship, and the courage to break through shown by the "big sister" are even more impressive to colleagues. During the "Long March 5" Yaosan rocket test mission, Zhou Chengyu was positioned at the secondary connector gas distribution station located on the 15th floor of the umbilical tower. The road to the 15th floor is a 180-level steel platform with an inclination angle of nearly 90 degrees, so it is difficult to walk upright in many places, and it is necessary to use both hands and feet to climb up, like a "ladder". It is difficult for normal people to run once, and Zhou Chengyu sometimes goes back and forth four times a day.
The 15th floor working environment, with less than 8 square meters of space and no air conditioning, is enough to make people feel terrified – the test room is equipped with 2 gas distribution tables, 4 adapter boxes and hundreds of cables and gas supply lines. Although there are only 3 people working inside, there is no place for everyone to sit, and they have to endure the noise of high-pressure gas flowing at all times. In such an environment, Zhou Chengyu insisted on working for 60 days, and he was not late for a day. The re-flight battle of the "Long March 5" rocket left Zhou Chengyu's arduous footprints.
At the same time, she is also the most frequent changing of guards in the power system team of Wenchang Launch Site. Every change of guard requires great courage. The requirements for knowledge and ability in different positions vary greatly, which requires Zhou Chengyu to always insist on learning. It is also this spirit that allows her to adapt to different positions as soon as possible.
The first time Zhou Chengyu made his first shot, he undertook the "Chang'e 5" mission and became the first female conductor of the entire launch site.
She looks calm, but there is a lot of pressure behind her.
Because the working principle of the connector system is quite complex, and the equipment is widely distributed and there are many coordinated interfaces, if you are not careful, you will step on the "thunder". Zhou Chengyu must tense his nerves at all times, and he cannot appear at all.
Not afraid of suffering, dare to climb, brave innovation, this is a new generation of astronauts.
It is precisely because of the young generation of astronauts like Yu Xinchen, Bao Shuo, and Zhou Chengyu who have aerospace dreams, are full of vigor and hope, and are constantly working hard that we have completed a huge and complex aerospace project.
Today, they are taking on new challenges.
Post-90s astronauts interpret their responsibilities and responsibilities with actions, and from them, we also see the infinite bright future of China's aerospace.
