Light up the vast starry sky with knowledge

  Looking out from the porthole of the Chinese space station, the blue earth is full of vitality, surrounded by a deep universe full of unknowns. In addition to the beautiful scenery that cannot be seen enough, the three space lectures are also fresh in my memory. I sincerely hope that through this meaningful space class, young people’s interest in advocating science and knowledge-seeking reading will be stimulated.
  In 2013, I taught for the first time. In just 40 minutes, I opened a “door of science” for children. After returning to the ground, I received many letters filled with childlike innocence and enthusiasm for knowledge. Some said, “I also want to fly into space and explore the mysteries.” Some said, “Please pass the baton to me!” Many children asked, “When will there be space classes again?” With these expectations, after eight years of unremitting efforts, “Mr. Yaping” finally succeeded in chasing his dream again and ascended the “podium”. During the Shenzhou 13 mission, I completed two space teaching activities with Zhai Zhigang and Ye Guangfu. The astronauts’ in-orbit work and life scene display, the cytology experiment in the microgravity environment, the space parabolic experiment… The content is more abundant, and the scientific equipment is more advanced.
  Some classmates wrote to me and uploaded them to the Chinese space station after listening to the class. I replied happily: “As long as you dare to chase your dreams and chase your dreams, you will be able to usher in the launch moment of your dreams.” This kind of interaction reflects the aerospace industry. An Invocation and Inspiration for Adolescent Science Literacy. As the science fiction writer Liu Cixin said: “The best part of the space class is that, like a paintbrush, it depicts a space world different from the earth’s gravity world for children.”
  Becoming an astronaut is a process of constant knowledge. During the selection and medical examination, I ran into Yang Liwei while walking and asked curiously, “What’s the hardest thing about being an astronaut?” He just said two words: “Learn.” After that, I became deeply aware of these two words. amount of. In the first year of joining the team, we have to study more than 30 courses such as aerodynamics, astronomy, advanced mathematics, and aerospace medicine. Knowledge reserve is like building a house. It must be done little by little, and there is no shortcut. The daytime is full of courses, and the homework, preview and review are done at night. The lamp on the desk has never been turned off before midnight.
  In addition to the “hardcore” expertise, literature and reading aloud also accompany our life in space well. Our Shenzhou 13 astronaut crew read the general preface of Ba Jin’s Torrent Trilogy, which is called “poetry from afar”. In addition to work and training, I also relax by watching movies, especially science fiction. Whenever I see the experience of astronauts on the screen, my heart resonates strongly, and while watching, I recall my days in space. Walking out of the cinema and looking up at the sky, I can’t help but think of myself lying on the porthole looking at the earth from a distance, and my love for the aerospace industry spontaneously arises in my heart, which is an unforgettable intoxication.
  Now that I have returned to the ground safely, I am still eager to take my children’s scientific dreams to space again, complete new explorations, light up the vast starry sky with knowledge, and continue to write new brilliance in China and human spaceflight.
