When the spring breeze once again blows green into the northwest Gobi Desert, when the millennium poplar trees on the banks of the weak water once again bloom with tender leaves, and when people's attention once again focuses on Dongfeng Aerospace City, the Shenzhou 20 manned flight mission begins - at 11:00 on April 23, the three astronauts who carried out this mission made their first public appearance. Chen Dong served as the commander and was the first astronaut in China's second batch to make three space flights. The astronaut Chen Zhongrui and flight engineer Wang Jie, who achieved their dream of flying for the first time, are both the third batch of astronauts in China. The day they went to Tianyu was determined by the mission headquarters to be 17:17 on April 24th. 55 years ago, China's first artificial satellite, Dongfanghong-1, was launched on this day, playing the prelude to the exploration of space by the Chinese nation; Ten years ago, the State Council approved the establishment of this day as "China Aerospace Day", giving China's aerospace industry its own holiday. Chasing dreams, the sky opens up a new journey, and the spirit is hard to write about with the colors of red and blue. Since the Chinese nation's dream of flying into space came true in 2003, 26 flying heroes have appeared in the Wentian Pavilion. They have gone on expeditions for the motherland, marked new heights of Chinese exploration in space, fulfilled the clank oath of "willing to fight for manned space for life" with practical actions, and constantly wrote new era chapters in the Chinese nation's progressive history. Chen Dong: The second batch of astronauts who flew three times in China's first three flights still excited Chen Dong. Every space journey is unique, and we look forward to gaining more experience and breakthroughs through flying He said. On October 17, 2016, Chen Dong achieved his dream of flying into space and embarked on his first space journey. When the fairing was just opened, he looked out of the porthole and couldn't help but exclaim, "Wow! It's very beautiful!" Commander Jing Haipeng immediately asked, "Are you feeling good?" Chen Dong replied, "Especially beautiful." Jing Haipeng then asked, "Do I ask you if you're feeling good?" Chen Dong replied with a smile, "Great!" That year, Chen Dong was 38 years old. At that time, he still seemed like a novice, with infinite longing for the universe shining in his eyes, and a huge enthusiasm overflowing in every move he made. In 2022, Chen Dong was given the opportunity to fly again and served as the commanding officer leading the expedition for the first time. He said, 'This time, my body and blood also have space memory, and I feel basically no discomfort.' This is the first manned flight during the construction phase of China's space station. During the 183 days of living in space, Chen Dong and his teammates experienced 9 combination configurations, 5 rendezvous and docking missions, 2 separation and evacuation missions, and 2 transposition missions. They fully completed the construction of the space station with Tianhe core module, Wentian experimental module, and Mengtian experimental module as the basic configurations, creating multiple "firsts" in the history of China's manned spaceflight, and were known as the "busiest crew". On November 17, 2022, the crew of Shenzhou XIV carried out the third extravehicular activity. This is the first extravehicular activity after the completion of the basic configuration assembly of the space station's "T" shape, and the first time that the large and small robotic arms have "merged" to cooperate in operation. On that day, Chen Dong stood on the robotic arm, with the vast deep space above his head and the space station and Earth beneath his feet. Quietly, he felt an unprecedented visual impact amidst it. I saw the magnificent panoramic view of the space station Chen Dong recalled that the space station slowly flew around the Earth's home, and the blue sea and white clouds decorated the Earth like blue and white porcelain, creating a sense of pride. He said he is proud of the crew, proud of the millions of aerospace technology workers, and even more proud of the great motherland. Chen Dong's WeChat avatar is a photo of Zhang Weimei, and he will change it every now and then. These photos were taken from the portholes during his mission. After returning from space, Chen Dong couldn't forget the starry sky. "I used to want to go to space, but now I want to go even more. In 2024, Chen Dong was selected as the crew member of Shenzhou 20 and once again served as the commander, accompanied by two new teammates who were flying for the first time. I will give it my all, concentrate my energy, and lead the crew with more profound professional skills to complete all the assigned tasks Facing the reporter, he remained calm and composed. Chasing dreams in the sky, conquering the stars three times. For Chen Dong, time has not only accumulated a few silver strands on his temples, but also polished a calm and composed demeanor. According to the plan, this mission involves both complex extravehicular activities and meticulous experimental operations, as well as challenges such as daily maintenance and repair. Once the ride group was established, Chen Dong and the instructor team tailored personalized training plans based on the characteristics of the ride group and tasks, scientifically planned the course sequence according to task priorities, and increased training frequency for weak links. Our crew adheres to the principle of 'having more hands on the ground is the only way to be proficient in space'; The concept of 'putting in all effort on the ground, space can respond effectively' Chen Dong said. During those days in space, after a busy day of work, Chen Dong would always lie by the porthole and gaze at Earth, searching for the outline of his motherland. When I look at my motherland, I feel as if it is also gazing at me. We are like kites, no matter how high or far we fly, the other end of the string is always tightly held in the hands of our motherland Chen Dong said, "The motherland sent me into space, and I am guarding the Heavenly Palace for the motherland." Chen Zhongrui: The space pilot who dreams of becoming a tractor driver waved calmly to Chinese and foreign journalists through the huge arc-shaped glass, with a warm smile on his face. The Wentian Pavilion at Jiuquan Satellite Launch Center became the starting point for him to realize his dream of flying into space. And the starting point of his life dream is to return to his hometown - a place called Chen Dazhao Village in Huaxian County, Henan Province. When he was a child, Chen Zhongrui's dream was to become a tractor driver. When he first learned to walk, he staggered onto the tractor and learned how to operate it like an adult. When he was in elementary school, watching adults drive tractors to farm the harvested wheat made his heart itch. At that time, as soon as his foot could press the accelerator, the adults were afraid of danger and wouldn't let him drive. He was so aggrieved that he burst into tears. During the summer vacation after graduating from junior high school, a chance encounter planted his dream of flying in his heart. He thought, isn't flying a plane in the air more impressive than driving a tractor on the ground? It is said that recruiting pilots requires high physical fitness. During his three years in high school, Chen Zhongrui had to wake up half an hour early every day to go for a run on the playground and train with sports talents... In September 2003, Chen Zhongrui was admitted to the former Air Force Changchun Flight Academy and became a flight student as he wished. After nearly two years of intense and solid learning and training, Chen Zhongrui welcomed his first experience of flying in life. That day, Chen Zhongrui piloted a fighter jet soaring above the white clouds, and under his control, the plane did not sway or deviate, flying out on a stable trajectory. Later, he was one of the first batch of flight trainees to fly solo. One day in November 2003, snowflakes were drifting in the sky. School notice: All students gather in front of the auditorium. In no time, a group of people surrounded a nimble soldier passing by him - space hero Yang Liwei went to school to give a report. That year, Yang Liwei entered space aboard the Shenzhou V manned spacecraft, fulfilling the Chinese nation's millennium dream of flying to the sky. This is my first time interacting with astronauts Chen Zhongrui said. Ten years later, he had another encounter with astronauts. When Shenzhou 10 returned to Earth, I was on a training mission in the air and received instructions to clear the airspace to welcome the astronauts home. These two experiences made Chen Zhongrui have a deep desire in his heart when flying the plane - to fly higher, even higher, to break out of the atmosphere and appreciate the vastness of space. In 2018, the third batch of astronaut selection work in China was officially launched. Chen Zhongrui signed up without hesitation and, through rigorous selection, turned his dream into reality. From the sky to space, from a pilot to an astronaut, Chen Zhongrui has faced hardships step by step, and Guan Guan is sad. Completing over 30 theoretical courses within a year is very challenging for him, who is in his 30s and returning to the classroom. There are many professional courses such as thermodynamics and orbital mechanics, which are completely unfamiliar to me. When he was a pilot, he used to memorize the operation manual thoroughly before operating it. As an astronaut, not only do you need to refer to the manual step by step, but even the crew needs to work together according to the manual to ensure that every step and operation is accurate and error free. He had to exert great effort to change the way of thinking and operating habits he had developed before, and eliminate the muscle memory that had been imprinted on his body through unremitting efforts. Follow this arduous journey to reach the sky. Through adversity, straight to the stars. After being selected for the Shenzhou 20 crew, Chen Zhongrui deeply understands that every operation and detail in space is related to the success or failure of the mission, and ground training must be precise and accurate. Every time there is a large-scale experiment or operation, Chen Zhongrui strives for excellence and pursues perfection. He repeatedly memorizes and familiarizes himself with the task process and operation manual, deducing and practicing over and over again. The commander Chen Dong commented on him like this: "Good psychological quality, calm and calm. The operation is quick, steady and reassuring." For so many years, whether as a fighter pilot or an astronaut, Chen Zhongrui can still find the joy from his childhood when operating machinery: "This is a natural feeling, the more complex the operation is, the more excited it will be." On April 24, Chen Zhongrui and his teammates will ride the Shenzhou spaceship to the "Space Home" of Chinese people. This space pilot, who aspired to be a tractor pilot in his childhood and later became a fighter pilot, will soar higher and higher in the nine heavens this spring. Wang Jie: From manufacturing spacecraft to riding spacecraft, the aerospace engineer Bayannur in Inner Mongolia means "rich lake" in Mongolian. For thousands of years, agricultural civilization and nomadic civilization have collided and blended here, giving birth to a "Jiangnan on the Great Wall". Wang Jie was born in a small village in Urad Front Banner, Bayannur City. In October 2003, astronaut Yang Liwei returned from outer space and landed on the grasslands of Siziwang Banner, Inner Mongolia. Wang Jie, who was still a high school student, heard about the profession of astronauts for the first time and began to have curiosity and longing for the aerospace industry. In 2018, the third batch of astronaut selection work was launched. This time, based on the requirements of the space station mission, the selection scope has been further expanded, not only selecting space pilots from the Air Force, but also selecting space flight engineers and payload experts from relevant research institutes and universities. This is the first time in our country. At this time, Wang Jie had already graduated from graduate school and became a researcher at the Fifth Academy of China Aerospace Science and Technology Corporation. Feeling that he met the requirements in all aspects, Wang Jie registered to participate in the selection. He has performed well in clinical medical examinations, aerospace environment adaptability endurance, psychological testing, and other selection processes. He successfully passed the preliminary selection, multiple selection, and final selection, and officially became a space flight engineer among the third batch of astronauts in China in September 2020. The challenge arrived as scheduled. After a physical test of 3 kilometers, Wang Jie fell behind while running and was quickly "trapped" by fellow astronauts who were also Air Force pilots. Although it's not the last place, it's still counted down Wang Jie still felt embarrassed when he mentioned this matter. The simulated weightlessness water tank extravehicular activity training is even more difficult for Wang Jie. He needs to wear underwater training clothes, control his body posture with both hands, complete extravehicular transfer, upper and lower robotic arms, equipment assembly, and other operations. Each training session lasts for five or six hours, requiring physical strength
