The seeds of dreams have blossomed ■ PLA Daily reporter Wei Yumeng correspondent Wu Futong In recent days, the news of "falling from the sky" has made everyone look forward to it - "the first space teaching activity of" Tiangong classroom "of China space station is about to begin!" At this moment, looking up at the stars and tracing the footprints of the rapid development of China's manned space industry, people realize that it has been eight years since the first teaching of Chinese astronauts in space. The novelty and shock brought about by the space lecture recorded in history are unforgettable to the Chinese people—— This is the largest classroom in the world and appears in the new era of China's aerospace. This class has the highest podium: it is located in space more than 300 kilometers away from the earth; This class has the most students: 60 million primary and secondary school students and hundreds of millions of spectators. This is a magical class. For example, science fiction writer Liu Cixin said, "the greatest thing about this class is not to simply show a few knowledge points, but to describe a space world different from the earth's gravity world for children like a brush." On the morning of June 20, 2013, a lecture hall in remote space opened the skylight of thinking for many children on the earth. When the two gyroscopes drew different wonderful tracks in weightlessness, and when teacher Wang Yaping's beautiful face was reflected in the water ball, at that moment, the children not only saw the sky where the dream took off, but also felt that a seed called "aerospace" was planted in their hearts. From the first space lecture on the Shenzhou 10 mission to the six-month stay of the Shenzhou 13 crew in the space station, the children sitting in the ground classroom witnessed the rapid development of China's aerospace industry and realized the joint growth of their own life. Under the watering of time, the seeds of dreams have blossomed. On the road of pursuing dreams, every flower blooms colorful. Eight years ago, Wang Nan, who was also the representative of physics, was amazed at the real performance of the theory in the textbook; Eight years later, she has become an aerospace researcher, contributing her wisdom and strength to the Chinese nation's march towards the depths of space. 13 years ago, 7-year-old Wang Jingtian squatted in front of the TV to wait for the launch of Shenzhou 7 spacecraft. The shock of the huge roar of the engine made him jump from the ground excitedly; 13 years later, he witnessed the launch of Tianhe core module in Wenchang, Hainan, and made Aerospace Science Popularization videos with like-minded friends to convey more the charm of the times of China's aerospace. In 2022, a satellite musical instrument device called "cosmic music box" is planned to be launched. It will collect waveform data from outer space and listen to the voice of the eight wastelands of the universe. Its designer is a group of students from Tsinghua University and the Central Conservatory of music. Eight years ago, they also listened to the "first space lesson" that ignited their dreams among the 60 million primary and secondary school students. There are more children who bring into their work the "vision and mind of family and country and benefiting the world" and the "scientific spirit of seeking truth from facts and pursuing truth" learned from the "aerospace" lesson. Look up at the stars, down-to-earth and work hard. With a dream, you have the courage and perseverance to explore the unknown world. This is not only a personal Aerospace dream, but also the flying dream of the whole nation. In the vast universe, the future of dream seeds will become a gorgeous garden. Some people say that part of the "Chinese dream" is to be done in space. The development of China's aerospace industry not only means the improvement of the country's comprehensive national strength, but also an era card for the great rejuvenation of the Chinese nation. Since we planted the first seed in the 1950s, generations of astronauts have been going forward to overcome difficulties. Every time the predecessors make progress, they plant a seed of dream in the hearts of future generations. On the "road to heaven", from satellite launch to manned spacecraft, from space teaching to space station construction, Chinese voice, Chinese face and Chinese steps have left an eternal imprint in space. For decades, the seeds of dreams have blossomed, and more seeds are waiting to be bred. "The dream of flying never loses weight, and the tension of scientific dream is unlimited." keep curious and explore, and dream is the source of eternal vitality and vitality. A nation with dreams will be a nation that continues to make progress! On June 20, 2013, astronaut Wang Yaping gave a space class and started a dialogue with students. Data picture Letter to Wang Yaping The "heavenly palace class" has begun! In the twinkling of an eye, more than a month has passed since the Shenzhou 13 flight crew entered the Tianhe core module. During this time, in addition to adapting to the space environment, carrying out extravehicular activities and completing space station related technical verification, the three astronauts residing in the "heavenly palace" also prepared a new "open class" for the children in the earth's home. As eight years ago, the lecturer of this class still has our familiar Teacher Wang Yaping. But what is different from eight years ago is that the platform of this class is larger - in the space station built by China, there will be two experimental modules of "asking heaven" and "dreaming heaven" in the future; The content of the curriculum is richer - new links such as space cytology research experiment display, buoyancy loss experiment, effervescent tablet experiment and so on are added. At the same time, the students attending the class have also changed. In front of the screen, not only the majority of teenagers are watching carefully, but also a group of people are listening to lectures from space for the second time. The children who were amazed by the experiments of gyroscope and water polo have grown up now. Once ignorant pupils have gradually understood the mysteries of science. Some of the middle school students in those years entered the University and continued to move forward towards the palace of deeper knowledge; Some of them go to work and struggle for the career they choose. The magic of time lies in the moment when dreams are planted. Eight years ago in the summer, they saw the flash of their dreams through a special class. Eight years later, before the first space teaching of the "Tiangong class" on the Chinese space station, many children of the "space class" wrote a letter to teacher Wang Yaping, who planted the seeds of their dreams. Now, let's open the treasure of time and see what they want to say. —— editor The stars live up to the dreamers Dear sister Yaping: All along, in my mind, you are not only a calm and resolute flying hero under severe training conditions, but also a kind, lovely, professional and rigorous space teacher in the camera. Over the years, I have regarded you as a goddess of worship and an example of struggle. Now I am very excited to have the opportunity to communicate with you by letter. But at this moment, I would like to take you as a close sister Yaping and say something from my heart. In June 2013, I was still a sophomore studying in Gaomi No. 1 middle school in Shandong Province, and you have been identified as one of the members of the Shenzhou No. 10 crew, preparing for the final stage of the flight mission. When I first saw your picture on TV, my family praised you as "talented and beautiful"! I don't know what kind of mood you felt a few days before the launch? I've been looking forward to this live broadcast every day since I learned that there will be space lectures in Shenzhou 10 mission - I can see and hear what you say in space in a few seconds. In those days, the words "teaching in space" were still very strange to everyone, and the students around me didn't understand it. Why did I always feel elated when I mentioned it. Therefore, I not only want to watch the live broadcast myself, but also want to watch it with the whole class and even the whole grade. I'll never forget that morning. At 10:00 on June 20, 2013, we couldn't wait to turn on the TV. When I and more than 50 students in my class saw your gyro, pendulum and water polo experiments demonstrated in weightless environment, as well as various stunts that are difficult to achieve on the earth, the emotion surging in my heart is difficult to describe in a single word. I am amazed at the wonderful sparks from the collision between the special space environment and ordinary physics experiments. I am glad that the "Newton's law" and "cosmic speed" just learned in the textbook have been verified by you in such a special and intuitive way. I am moved by the light in the eyes of the students around me - the magic of space exploration and the charm of astronauts have finally been seen by more people Understand! In the "water polo reflection" lens, your big watery eyes and the water polo with flowing waves complement each other, as well as the witty sentence "you see, you can still see my reflection through the water polo". The whole picture has become the most beautiful and beautiful memory left to me by the "space classroom". Later, the college entrance examination was over. When filling in the volunteer, because I can always hear "so and so measurement and control station" or "so and so measurement and control ship" in the launch live broadcast, I did not hesitate to fill in all the preferred majors of the six parallel volunteers as "automation" or "measurement and control". This is to be closer to you and the aerospace industry. Finally, I was admitted to the school of control science and engineering of Shandong University and entered my favorite measurement and control major. In the four years of college, I still didn't give up my interest in "Aerospace Science Popularization". In 2016, Tiangong two launched, and I began to use my spare time to carry out the "heavenly palace diary" space science popularization articles on the WeChat official account of the college. Although the road of space science popularization is not as easy as expected, I still want to sow the seeds of space dream in the hearts of more people as you did in your space teaching. As long as the words I write can make more people know more about aerospace, even a little, is great happiness for me, and my efforts will not be in vain. In September 2018, I was admitted to Beihang University, a school I yearned for but missed in the college entrance examination. Coincidentally, when you were a high school student in Tiangong No. 1, you explained to me "the axis fixing of the top"; Now, sitting in the laboratory of Beihang, I have studied the gyroscope in the inertial navigation system. Maybe this little top is to maintain the rotating and unswerving fate between me and you! Finally, as a Chinese, I would like to thank you and tens of thousands of astronauts for their dedication to the motherland's aerospace industry, fearless of difficulties, dangers and sacrifices. As an ordinary girl, I want to say: sister Yaping, thank you for being like a dazzling star over the years, always guiding and encouraging me to strive forward. Perhaps all along, you don't know who I am, but you have already become the light I yearn for on the way to pursue my dreams. In the future, I will continue to follow your example and contribute my own small but firm strength to China's aerospace industry. Wang Nan December 2019 (now, Wang Nan, who wrote the above letter, has graduated from graduate school and has officially become an astronaut. As written in the letter, she keeps running on the road of pursuing her dreams and tries her best to release her light and heat for the development of China's aerospace industry.) There is a record called growth To Mr. Yaping and all astronauts: On the afternoon of September 25, 2008, the sun was directly on the playground of the mother's unit. That day was the school sports meeting. The students were sweating on the playground. When I
