How her “golden fingers” were made when “Wentian” was launched into space – Liu Jinjie, engineer at Wenchang Aerospace’s Jamaica Suger Baby app launch site
When thunderous applause aroseJM Escorts Test launch at Guowenchang Space Launch Site When the sound rang out in the hall, Liu Jinjie did not react for a moment. She recalled that moment to reporters from China Women’s Daily, “When I raised my head, I realized that everyone was clapping, and I was half a beat too slow. ”
At 14:22 on July 24, 2022, Beijing time, as Commander 01 shouted the “burn” command, Liu Jinjie, who was in charge of the dispatch control station, steadily The white “burn” button was pressed steadily, and the Long March 5B Yuan-3 carrier rocket carrying the Wentian test module burned and launched on time at the Wenchang Space Launch Site. In the aerospace industry, the person who finally pressed the red button is known as the “Golden Finger.” Liu Jinjie, 33, is the first female “Golden Finger” to welcome the Wenchang launch site to the launch control station.
Becoming a “gold finger” is the dream of every astronaut working in the control system. It took Liu Jinjie seven years from the day he walked into the Wenchang launch site to the realization of this dream.
Getting involved in aerospace, “I lost my hair halfway”
Unlike many of her colleagues who have dreamed of aerospace since childhood, Liu Jinjie is actually an astronaut who “finished her career halfway”. She graduated from the National University of Defense Technology, and her undergraduate and graduate studies were in applied mathematics. , system superstition. Due to his excellent grades in mathematical theory and programming, Liu Jinjie joined a research institute in Beijing after graduating in 2013, and soon became a technical expert in the institute. If she had not left the Wenchang launch site, Liu Jinjie might have become a very good scholar, but a visit to relatives changed her personal work life and closely linked her to the aerospace industry.
At that time, Liu Jinjie’s husband Li Fan was working at the Wenchang launch site. His busy work meant that Li Fan rarely had time to contact his wife. The most exaggerated time was when Liu Jinjie Jinjie didn’t get through her husband’s phone call for several days, “That time he was participating in the compulsory training period, and I couldn’t contact him for many days. Although he had called me in advance, I I was still a little anxious and felt a little ‘strange’. What kind of situation could make him have no time to make a phone call?” Recalling my dissatisfaction at that time sugar.com/”>Jamaicans Escort Understandably, Liu Jinjie also felt a bit “ridiculous”.
In 2014, Liu Jinjie came to Wenchang for the first time to visit her relatives. Her husband asked her to take her to learn about the rocket. Although she had seen a lot of aerospace reports on TV, when she actually stood under the rocket, Liu Jinjie felt an unprecedented shock, “I still remember the mood at that moment. The rocket was so majestic and spectacular! ”
The moment she stood under the rocket and looked up, her yearning for the aerospace industry took root deeply in Liu Jinjie’s heart. After returning to Beijing, she began to apply for a mission After the transfer, she finally entered the Wenchang Launch Site in November 2015.
At that time, the Wenchang Launch Site was in a “three new” state: New launch site, new rocket, new personnel
As a newcomer, Liu Jinjie’s first launch mission happened to be the first launch from the Wenchang launch site. Task: The launch of the Long March 7 Yuan-1 rocket. At that time, the first task she was assigned was data processing, “because my specialty is mathematics, and data processing is a relatively basic and entry-level position in the control system. , this position requires monitoring of various parameters. Through these parameters, you can quickly get started and understand and become familiar with the entire control system. ”
Faced with the new surrounding environment and job position, Liu Jinjie quickly stepped into the role and showed her characteristics as a “student master”. Not familiar with the aerospace field, she She found a lot of job technical materials and studied them one by one. When she had almost learned the theory, she ran to the scene again and “badged” the old operators to learn the principles of equipment. After returning home in the evening, she was also very excited. Take less rest, but continue to study overtime and summarize your own experience and experience.
After 7 years of hard work, I have overcome three difficulties.
Over the years, more and more women have made outstanding contributions in the field of aerospace, from astronauts Liu Yang and Wang Yaping who entered space, to Liu Jin Jie and her female colleagues, they are shining in the aerospace field and using their own stories to demonstrate the power of women. In Liu Jinjie’s view, every opportunity that women get in the aerospace field is hard-won. She told reporters: ” If female astronauts want to be seen, they need to overcome three difficulties. ”
The first hurdle is the psychological barrier, “The aerospace field is originally a place where there are more men than women. Jamaicans Sugardaddy At our Wenchang launch site, the male to female ratio exceeds 20:1.Due to physical, psychological and other reasons, sex will be set to a relatively “relaxed” position more often than not, and you will not be allowed to take the lead. “Liu Jinjie’s character as a hot girl from Hunan made her decide to break through the psychological barrier.
Up to now, the Wenchang launch site has carried out a total of 18 launch missions. Liu Jinjie Participating in the guarantee and witnessing 17 times, it can be said that Liu Jinjie grew up with the Wenchang launch site. The only launch she missed was the launch of the Tianchuan-1 cargo spacecraft on April 20, 2017. JM Escorts The Zheng-7 Far-2 rocket was launched. On that day, Liu Jinjie’s son An An was born and was called “Sky Boat One” by the master. baby”.
After the birth of her child, Liu Jinjie quickly returned to work. Before her maternity leave was over, she started researching the topic without being able to take any time off. .
After taking maternity leave, she rotated to the position of the front end of the launch control. When performing tasks in this position, she needs to climb the 16-story umbilical tower (a kind of cable tower used to support test cables, etc.). (Fixed or tilt-down tower with gas supply pipelines, etc.). After the umbilical tower reaches the 12th floor, it almost requires the use of both hands and feet to climb up. It is not difficult for most people. At that time, Liu Jinjie weighed 160 kilograms. Under the pressure of the heavy weight, she had to raise and lower the umbilical cord tower twice a day, which caused serious fluid accumulation in her knees, but Liu Jinjie never cried out in pain. She never missed a mission. When she got home every night, the infrared therapy device and plaster became her must-haves. When she got up the next day, she continued to control the 16-story umbilical cord tower.
The second hurdle is the psychological hurdle, which is from the inside to the outside. From the most basic data processing to becoming a “gold finger”, Liu Jinjie also had self-doubt. At the moment, Liu Jinjie said that he had thought about giving up several times, “but sometimes after giving up, I still felt reluctant, so after thinking about it, I picked up my dreams and kept moving forward. ”
Many people asked Liu Jinjie, “If you can’t climb that (umbilical cord) tower, why do you have to climb it?” You can’t get into this cabin, why don’t you just forget about it? “Faced with such a question, Liu Jinjie gave the answer: “If I find a reason to shrink from every difficulty, I will have no way to prove that I can do what others can do, let alone have the opportunity. Enter the master’s vision. More people will feel that “lesbians are just squeamish and squeamish” and will wear such colored glasses. I want to prove that I can do it, that there is no difference between me and gay men. ”
” After passing the first two levels, will there be no chance of becoming a “gold finger”? Liu Jinjie told reporters: “Overcoming the first two difficulties can only prove that you are no different from others, and you are not enough to reach the position of ‘gold finger’. You have to give everyone more powerful persuasion.”
In the seven years since Liu Jinjie left the Wenchang launch site, she has played almost every position in the control system. From data analysis, application and processing to familiarity with rocket principles, she has performed well in every position. Grow into a responsible person.
In addition to his busy work, Liu Jinjie also spends all his time devoted to scientific research. “In the process of training for each position, I set a small goal for myself, that is, every time I take a position, I have to write a paper or do a research, and I must solve a problem.” More than 7 years of experience. During that time, Liu Jinjie published more than 20 papers in core journals, putting forward his own opinions on the basic theory of each position and the improvement of working methods.
Seven years of hard work have turned Liu Jinjie from an “aerospace amateur” to a master of technology in controlling the system, and also made her closer and closer to the dream of “gold finger” The closer.
Purpose: From “Golden Finger” to No. 1 in the entire system
It was the autumn of 2021 when he learned that he had been selected as the “gold finger” for the Wentian test module launch mission. At that time, Liu Jinjie’s first reaction was “both unexpected and unexpected.” Unexpectedly because of joy and surprise, but also because after these 7 years of hard work, I feel that I am ready.”
In the eyes of ordinary people, “golden fingers”. The last action of pressing the button is cool, but behind this small action is more than simply listening to Commander 01’s “burn” command and moving his fingers.
As the “nerve center” of the rocket control system, the launch console has more than a hundred buttons, each button represents a control command, and there are nearly 300 buttons on the four monitors. Parameters and status lights, each parameter represents the status of different front-end devices. This not only requires the “gold finger” to be familiar with the entire rocket test and launch process, but also requires an overall thinking.
In order to meet the needs of the Wentian test module and the space station assembly for rendezvous and docking, this rocket launch chose a “zero window” launch (referring to the error between the rocket launch time and the scheduled burning time cannot exceed 1 second), this is also the first time that my country has carried out a “zero window” launch of a high-thrust rocket. “‘Zero window’ launch means that the launch time needs to be planned in advance and the rocket will be fired into the sky in every second. This puts a higher challenge on the ability of ‘Goldfinger’”request, because this means that I have to be more familiar with the relevant emergency handling situations. Every time I detect an exception one second earlier, I can buy more time for the launch window to make corrections. Liu Jinjie explained.
Liu Jinjie said: “The biggest challenge for me in this mission is to quickly identify abnormal parameters.” “To put it simply, it means being able to quickly discover problems. When a person encounters a problem in a high-pressure situation, the first reaction may be to be stunned and “blinded”. This is a psychological reaction of human nature and it is difficult to avoid it. . But facing the rocket launch mission, Liu Jinjie needs to overcome all psychological reactions. When abnormal parameters occur, he must be able to directly enter the rational processing system and think about “what should I do?”
Such calmness cannot be developed in a few days, but requires years of study. Liu Jinjie and her colleagues adhere to this saying in their work: It is better not to encounter it than to not encounter it. Unexpectedly. “In the task preparation stage, we will preset all possible situations for each nodeJamaicans Sugardaddy. After careful consideration, I eventually formed hundreds or even thousands of plans to ensure that if any abnormal situation occurred, I could quickly call up solutions to all problems from my mind. ”
In the early morning of July 24, about 14 hours before launch, Liu Jinjie came to the test and launch hall in the dark to make final preparations for the launch mission.
At 14:21 on July 24, the last minute before the launch mission, as the “allow to burn” command was issued, the launch entered the final countdown: “50 seconds… …40 seconds…30 seconds…20 seconds…10, 9, 8, 7, 6, 5, 4, 3, 2, 1, burn! ”
Under the instruction of 01 commander Liao Guorui, Liu Jinjie pressed the red “burn” button, and the Chang 5B rocket, known as the “Fat Five”, rose from the ground. , the earth roared, Liu Jinjie looked calm and her voice was calm, but when we look back at the scene of her pressing the button, we will find that her hands are shaking slightly in the close-up shot
About 495 seconds later, the Wentian test module successfully separated from the rocket and entered the scheduled orbit. Thunderous applause erupted in the test and launch hall. We will never hesitate to face any problem. Liu Jinjie was stunned for a second, and then she and her colleagues clapped together. Wang Yumeng, a colleague sitting next to her, patted her hand quietly and said to her, “You are great!” ”
At the same time, his son An He happily and proudly introduced to the teacher and friends in the kindergarten, “My mother is a rocket launcher.”‘Goldfinger’! ”
Once upon a time, An An angrily said to Liu Jinjie, “You are not a good mother” because his mother did not have much time to accompany him, which made Liu Jinjie feel very uncomfortable. But the evening after the successful launch of Wentian, when Liu Jinjie came home and saw An An, his son gave her a big hug, “Mom, you are the best mother in the world!” “At that moment, Liu Jinjie felt very proud.
The launch mission of the Wentian test module was successful, but Liu Jinjie had no time to rest. She had to invest immediately for three months. During the subsequent launch of the Mengtian test module, she told reporters, “My next goal is to become the 01 commander of the control system as soon as possible, and to complete the transformation from the number one female in the control system to the No. 1 in the entire system. change. ”
Living in Hainan, Liu Jinjie likes the coconut trees that can be seen everywhere on the roadside. “There are many typhoons in Hainan. Coconut trees are often blown to the ground after the storm, but they don’t.” It will grow in the direction of the fall, but it will keep on the place where it fell, and continue to raise its head towards the sun. “Liu Jinjie hopes that she and all women who love the aerospace industry can be as strong as coconut trees. “It cannot be blown down by the sea wind or poured down by heavy rain. Look up at the stars and protect the mountains and seas.” ” (Xiao Rui, all-media trainee reporter at China Women’s Daily)
