The spirit of manned spaceflight has inspired generations of young people, "How can I become an astronaut?" "I'm sure many children have had such problems. Recently, the Zhejiang Provincial Science and Technology Museum's "Science and Vision" activity entered the Hangzhou Baochuta Experimental School, and the "Uncle Mars" Zheng Yongchun answered this question, Zheng Yongchun is also a planetary science expert and popular science writer.
At the beginning of the event, the science performance team of Zhejiang Science and Technology Museum brought a very interesting "Science Classroom". The teachers at the Science Museum recreated the classic Magdeburg hemisphere experiment with metal lids, cola cans and other common objects, allowing the children to witness the power difference caused by the air pressure difference.
In the sharing session, Zheng Yongchun brought two rocket models and threw the first question to the children, "What is the difference between manned rockets and cargo rockets?" The children scrambled to answer, some said the size difference, some said the function is different, and finally the child said the key point - the manned rocket needs to take into account the problem of the return capsule. Zheng Yongchun smiled and nodded, "That's right, manned rockets should consider more safety, comfort, and reliability." ”
What can you see in space? Zheng Yongchun showed pictures of the aurora in space, stars, and the earth's surface in space vision, and said, "Less than 600 people in the world have ever been in space," and then shared with the children how to become an astronaut.
In the early days, astronauts were mainly pilots, and now more and more people from other industries have begun to enter space, such as Gui Haichao, an astronaut of the "Shenzhou 16" crew, who is a professor at Beijing University of Aeronautics and Astronautics. Astronauts need to be very well-rounded, not only scientists who can complete scientific tasks, but also electricians, engineers, doctors, and even cooks because they have to deal with the unforeseen situations in space.
Zheng Yongchun told the children that in order to become an astronaut, they must first have excellent grades, and at the same time they should be full of a strong interest in science and aerospace, "you can only do this well if you really like one thing", and he encouraged the children to study hard and cultivate their comprehensive quality, not only to pay attention to astronomy and aerospace knowledge, but also to have a broad understanding of scientific knowledge in other fields. And astronauts not only need high intelligence, but also high emotional intelligence, after all, spending a long time with their companions in the sky requires good communication and getting along skills to cope with various challenges in extreme environments.
As Zheng Yongchun said, the aerospace industry needs more young people who are interested in science to join in. This event provided a valuable opportunity for the children to better understand the aerospace industry and stimulate their interest in science and desire to explore.
This year marks the 20th anniversary of the implementation of the "88 Strategy" and the 20th anniversary of the take-off of China's manned spaceflight. In order to commemorate this precious 20 years, the Zhejiang Provincial Science and Technology Museum introduced the "China Wentian" China Manned Space Engineering Science Exhibition in September this year. Before the start of the event, Zheng Yongchun also visited the popular science exhibition with the docent of the Zhejiang Science and Technology Museum. In this exhibition, children can not only learn about real spacecraft, but also learn about rockets, spacecraft, space stations, astronauts, and space life, and further inspire them to love and participate in science by witnessing the great achievements of China's manned space program.
The Science Pineapple Award hosted by the Zhejiang Science and Technology Museum will be held on the evening of November 11 at the Olympic Sports Center in Ouhai District, Wenzhou City, which is a scientific feast to pay tribute to curiosity, and this year's theme is "Everything can be followed, you are me", Zheng Yongchun is also one of the guests. It is believed that through such popular science activities and science festivals, more children will pursue their dreams in the temple of science and contribute to the realization of the Chinese dream.
ABOUT
In order to inherit the spirit of scientists, empower the development of the new era, and encourage and guide young people to learn the spirit of the older generation of scientists, Zhejiang Science and Technology Museum is driven by the responsibility of social science communication and based on core needs to create a new popular science brand - "Science and Vision". Through scientists telling the stories behind scientific research, scientists can see people, things, things, and spirits, which is amiable, respectable, sensible, and learnable.
