On the afternoon of September 21, the fourth lesson of "Tiangong Classroom" began, and Shenzhou 16 astronauts Jing Haipeng, Zhu Yangzhu and Gui Haichao taught space science popularization to young people across the country, demonstrating a number of wonderful scientific experiments in the microgravity environment of space. In this lecture, Beihang University is where the ground classroom in Beijing is located, and it is also the school where Gui Haichao works. After almost 4 months of space "business trips", his students met the teacher again on the "podium".
Su Wenjie, a direct doctoral student at the School of Astronautics and Astronautics of Beihang University and a student of Gui Haichao, was very excited to finally meet her mentor through video. "It is very wonderful to see these basic principles manifested in new ways in space through Mr. Gui's hands." Su Wenjie said that the space station is a great scientific research platform, many experiments that cannot be carried out on the ground can be carried out here, "I hope to see more experiments in space in the future, I also look forward to devoting myself to the space industry, maybe in the future there is an opportunity for Mr. Gui to take the spacecraft we designed and go to space again." ”
"Our space development is too rapid!" Just after class, Chen Haochu, a student of the primary school affiliated to Beijing Chaoyang Normal School, sighed, "I have participated in the first lesson of 'Tiangong Classroom' before, and today I have the opportunity to come to the scene again, and the principles explained in this class are more detailed. ”
As a teacher in this Beijing ground classroom, Zhang Xiaotian, associate professor of the School of Astronautics and Astronautics of Beihang University, and Gui Haichao made a "heaven and earth partnership". "Seeing Gui Haichao on the space station, just like I usually see his state in the office or laboratory, I am also very happy as his colleague." This time, Zhang Xiaotian and Gui Haichao lit candles on the ground and jointly demonstrated the experimental phenomenon of heaven and earth contrast for students.
Li Jingxuan, a professor at the School of Astronautics and Astronautics at Beihang University, was a neighbor of Gui Haichao, and his research direction was engine combustion. Under ground and weightless conditions, the stability characteristics of flames can vary greatly. "This lecture transports flames into space and conducts experiments under ideal weightless conditions, which is also a very valuable lesson for us combustion researchers."
"Teacher Gui's space trip this time is a process of turning dreams into reality for us Beihang students." Liu Rui, Secretary of the Party Committee of the School of Astronautics and Astronautics of Beihang University, said that this kind of teaching form of space-earth dialogue can give students greater encouragement, and I believe that under the drive of Gui Haichao, students will study harder, improve their professional level, and realize their aerospace dreams in the future. "I look forward to Mr. Gui returning to Earth and school, and then telling the students about his work status and research direction on the space station, exploring the development of new scientific payloads and carrying out new work together."
