We arrived at the Science and Technology Museum. Much more interesting than I expected. The whole science and technology museum is divided into four floors, and each floor has an exhibition hall with different contents. About natural science, such as gravity, volcanic eruption, the generation of lightning, the characteristics of major planets, etc. Related to mechanical power, such as: models of trains and airplanes, power generation principles, wind power generation principles, etc. About high technology, for example; Robot model, videophone, satellite navigation, submarine cable, etc. There is also our student paradise, in which there is a computer demonstration of the idiom "mantis catches cicada, yellowbird comes last", which is very interesting.
But what excited me most about this trip to the Science and Technology Museum was watching the simulated launch of manned spacecraft. The whole launch process is the same as the official launch. From taking off, speeding up, rushing out of the atmosphere, entering orbit and returning to the ground, the whole process seems to be immersive, with photos taken by astronauts in space and some plots of astronauts working and living in spacecraft. They do all their activities in almost zero gravity. One of the uncles threw away his flying book and pen. These small objects float in the spaceship in zero gravity, unlike the rapid landing on the earth. It's really interesting. My aunt also told us some aviation knowledge, which made us feel that space flight was really amazing. Especially through her explanation, I learned that from/kloc-0 "Shenzhou I" in 999 to "Shenzhou VII" in 2008, China finally realized the dream of the ancient and romantic fairy tale "the Goddess Chang'e flying to the moon". Our country is really great! Our astronauts are really amazing! However, the launch of Shenzhou VII spacecraft and the spacewalk of Chinese astronauts will be a new starting point for our space exploration. I think this wonderful dream will be realized by us at that time!
