November 12 at 10:03, accompanied by a deafening loud noise, the Long March 7 Yao6 carrier rocket held the "Tianzhou 5" cargo spacecraft and pierced the sky, sending "space express" to the Shen 14 astronaut crew, and the launch mission was a complete success. As an important battle in the final stage of the space station construction, the launch site staff were under pressure, fought continuously and persisted. After 12 days of the successful launch of the Mengtian Experimental Cabin, they won the final victory again, bringing a successful conclusion to the 2022 launch mission of the Wenchang Launch Site. Behind this, there is a group of children from the land of Hunan who stick to the island, look up to the empty heart, protect the construction of China's space station, and silently contribute to the aerospace cause of the motherland.

Liu Meng: A communications clerk who cares about the "Long March"

Liu Meng, male, born in November 1998, from Zhangjiajie, Hunan, is mainly responsible for communication support work in the "Tianzhou 5" mission.

communication system is one of the five major components of the launch site system and is also a basic project to ensure the smooth progress of various operations. If the communication is cut off, the command post will become blind and mute, and it will be difficult for major systems to operate normally. Liu Meng is an important node to ensure the smooth progress of communications at the accusation center.

Liu Meng's hometown Sangzhi County is the starting point of the Long March of the Red Second and Red Sixth Army Corps. The revolutionary spark sowing by the Red Army's Long March has been engraved in Liu Meng's heart since he was a child. He used his spare time several times to retrace the Long March and inspire the enthusiasm of the "Long March" in his heart.

In December 2019, Liu Meng came to Wenchang Space Launch Center with full enthusiasm for the "Long March" to continue his love affair with "Long March". He remembered the shock in his eyes and the excitement in his heart when he saw the rocket rushing straight from the launching tower. It is also here that he told himself that he should do his best to make every "Long March" launch vehicle successfully launch.

The qualities of the simplicity, enterprising and unafraid of hardships in the western Hunan Han Dynasty were extremely obvious in him. The job knowledge required for the communication position is significantly different from what he learned in college, but he took the initiative to make progress and humbly asked several seniors for advice. He learned command and dispatch, rapid editing system, and IPTV system, becoming an "insider" in the communication position.

When the equipment inspection was conducted after the Wentian Experimental Cabin task training, it was found that the IPTV system video recording function suddenly failed, which would directly cause the task data to lack important image information. All video files show that "the video storage has been overwritten by loop", and the manufacturer cannot provide an effective solution for this. Under the leadership of the team leader, they drew the fault tree, checked the problem points, and wanted to deal with it. After gradual investigation, they finally restored the system to normal. However, if such a problem occurs on the day of the mission, there is no such opportunity to slowly investigate it. Because the training has been completed, the equipment status has been frozen and large-scale changes cannot be made.

At this time, Liu Meng proposed that the IPTV virtual TV wall recording method can be used for emergency backup, so that there is no need to change the line, and the state changes are not large, which can perfectly meet the task needs. After asking the manufacturer, they quickly started discussions and practiced the feasibility. After the troubleshooting and emergency measures were verified, it was already early morning without realizing it. It is precisely with this meticulous work attitude and the double insurance that Liu Meng and his team can carry out communication guarantee tasks calmly and successfully ensure the smooth implementation of the Inquiry Task.

"Tianzhou 5" mission is only 12 days away from the DreamTian mission. During these 12 days, Liu Meng did not relax his requirements. He always upholds a rigorous and meticulous work style, works diligently and conscientiously, and does not miss any hidden dangers of problems and strives to escort the "Long March" to take off. Born on the Long March and learned from the Long March because of the Long March. Liu Meng said that he will always be passionate about the Long March, continue to work hard, go further, do his best to send more "Long March" launch vehicles into space.

Zhang Liang: The "Secretly Mile Eye" of Watching the Haiyuntian

Zhang Liang, male, born in April 1991, from Loudi, Hunan, is the main operator of the vehicle-mounted optical TV live recording system during the "Tianzhou 5" mission.

If it were not for the ambition to serve the country, Zhang Liang today might be a knowledgeable scholar or a clinician who saved lives and healed the wounded. And the choice nine years ago made him an astronaut.

In 2013, 22-year-old Zhang Liang graduated from Shanghai Jiaotong University and came to Wenchang Aerospace Launch Center. At that time, the conditions of Wenchang Aerospace Launch Center were still very difficult. Zhang Liang was not afraid of the arduous environment here and devoted himself to the initial construction of the launch site.

As the construction of the launch site gradually became complete, it had higher requirements for scientific research capabilities. Zhang Liang felt that his ability was insufficient. In 2015, Zhang Liang picked up the book again and studied for a postgraduate degree from Shanghai Jiaotong University. He successfully graduated and obtained a master's degree in 2018.

Returning to the launch site, Zhang Liang actively participated in the construction of a small-diameter optical live recording system in Wenchang launch site. Optical equipment tracking and measurement is a fine job. The small joystick controls a huge optical equipment with a variable orientation of 360°. It is a slight difference. If you are not careful, you may lose the target, resulting in the lack of task data collection.

htmlIn the past 2004, Zhang Liang has successively completed the compilation and improvement of textbooks, job test bank, job work instructions, emergency plans and other documents of the vehicle-mounted optical live recording system; he served as the commander of the vehicle-mounted optical live recording system to successfully complete many major test launch tasks such as lunar exploration, fire exploration, and space station. As the backbone of equipment technology, it completes the analysis and investigation of multiple faults such as equipment servo power failure, fiber splitter failure, interactive industrial control machine failure, system time failure, data loss, etc., to ensure the successful completion of various transmission tasks.

During the project development process, Zhang Liang not only wrote the program himself and repeatedly debugged it, but also had to manually interpret thousands of rocket flight pictures in the initial stage of machine learning. He was busy with work, so Zhang Liang took out the weekend to sit in front of the computer to handle the work. Finally, he achieved results in the early stage of the "Tianzhou V" mission and developed a video retrieval system to assist in the video analysis and interpretation of rockets after flight, effectively alleviating the pressure of data analysis work.

Zhang Liang introduced, "Don't look at it's very smart now. At the beginning, he was so stupid that he could use a burning candle as a rocket."

In addition, Zhang Liang also used his professional expertise to carry out a lot of exploration in data processing, image enhancement, and application of optical equipment. He also completed the research and implementation of key image registration, image enhancement, and object detection algorithms as the main person. Zhang Liang said that in the next step, he will explore more image intelligence algorithms and strive to promote the implementation of algorithms in the launch site.

Shi Min: Find important information in endless data

Shi Min, male, born in March 1989, from Changde, Hunan, currently an engineer in the first room of the Wenchang Aerospace Launch Center, and served as the operator of the software operation position of the center's machine subsystem in the "Tianzhou 5" mission.

Shi Min graduated from his master's degree in June 2013 and entered the Wenchang Aerospace Launch Center. He first worked in the communications subsystem and began his dream of pursuing aerospace. In his post, he studied carefully and trained hard, and completed many missions such as Changqi Changwu's first flight, Tianzhou-1, Changwu B's first flight, Tianwen-1 and Chang'e-5.

I remember that during the "Tianwen-1" launch mission, the telemetry decoding subsystem of the accusation center's telemetry and decoding system had several telemetry and decoding systems that had been continuously malfunctioned. The situation was urgent, and the staff of the post quickly responded and carried out troubleshooting overnight. As the pillar of the communication system, Shi Min immediately activated the emergency plan, combined with environmental conditions, coordinated power supply and distribution system, and screened for hidden dangers of power quality, and jointly investigated and researched the fault units, and repaired all the decoding units of the guarantee tasks to ensure that the tasks were carried out normally.

But the more you know about communication support capabilities, the more curious you are about aerospace measurement and control work, and the more you feel the shortcomings of your own capabilities. Communication provides services for measurement and control, so how does the measurement and control system operate? With this doubt and curiosity in mind, he gave up his position that had been on track and made achievements, and took the initiative to apply to transfer to the central machine system to meet new challenges.

Just arrived at the central machine position, Shi Min was completely confused. Unlike the working mode of the communication subsystem, this is the neural center of the computing. All the measurement and control data are collected here. The data volume is huge and the types are complex. What Shi Min needs to do is to search for important information in this endless data and perform preliminary processing and feedback to assist the commander's decision-making. With the belief of making up for what you can't do and what you lack practice, he began to learn new breakthroughs, worked hard, repeatedly learned and mastered equipment materials, practiced equipment operations, innovated processing and interpretation methods for different equipment data types, improved job abilities, gradually adapted to job needs, and became an excellent operator.

In this mission, in order to minimize the risk of failure and improve the emergency response capabilities of the entire team, Shi Min and his team conducted multiple emergency drills to simulate various possible failures and carry out targeted training.

12, with the successful launch of "Tianzhou 5", Shi Min and his team once again successfully completed the task. From identifying problems, dealing with problems, identifying data and analyzing data to identifying garbled codes to correct codes, Shi Min is working hard to innovate and make breakthroughs, constantly polishing and deepening the integration in practice.

Wu Bei: The trajectory of the rocket is the direction I pursue

Wu Bei, female, born in May 1997, from Changde, Hunan, is the commander of the vehicle-mounted radar subsystem in the "Tianzhou V" mission.

used to operate in Haidilao, but now he has changed his career to the field of aerospace measurement and control, and is a position operator for high-end and sophisticated equipment. Such a gorgeous turn is amazing. However, behind the stunning is Wu Bei's exponential hardships and efforts.

Due to the sharp turn of work, she made up for the theoretical knowledge of the relevant positions, and at the same time she practiced her operating skills boldly and carefully. When she encountered someone she didn't understand, she humbly asked the old comrade for advice, and finally successfully passed the on-the-job assessment.

radar equipment, coordination between positions is extremely important. As a novice, Wu Bei is determined not to be a team's shortcomings. He has to go through countless simulation drills in every task. She always maintains a high concentration of spirit throughout the whole process. She does her best every dispatching command, every operation, and every data command, and does it particularly rigorously and meticulously.

In just over two years, from an outsider who knows almost nothing to a successful execution of 8 space launch missions, Wu Bei's growth made the equipment manager Wang Lei feel deeply pleased. "I thought I was a delicate girl, but I didn't expect to grow into a capable female general so quickly!" The work on the

device is often a combination of brain and physical strength, so boys are more popular. In order to maintain the equipment, Wu Bei is not as good as a man and often climbs up to the top of the radar cabin like a gay man to do his work. The high temperature of Hainan for more than 30 degrees and the strong sunlight did not affect Wu Bei's patient and meticulous operation in the square cabin. Every time she checked, she would get soaked in clothes and tanned her face. When my father was videotaped with her, he felt distressed when he looked at her face that was darkened by the sun, but she said that she was doing a lot of fun, but she didn't expect that she could become a relationship with aerospace in this life and contribute her own strength to it.

In this "Tianzhou 5" mission, Wu Bei served as the commander of the radar subsystem for the third time with his strong comprehensive capabilities. Being a commander was a small goal when Wu Beichu set foot on the aerospace starry sea. It has been achieved now. Behind this is the personal practice and accumulation of every position in the sub-system. Wu Bei said: "The trajectory of rocket flight is the direction I pursue. As aerospace people in the new era, we are born at the right time and are fortunate to devote ourselves to the construction of the motherland's aerospace power. One day this dream will definitely be realized in our own hands!"
