From the Goddess Chang'e flying to the moon to the Cowherd and the Weaver Girl, fairy tales about the universe have always touched our hearts. Curiosity about the unknown makes humans fly, out of the atmosphere and into the universe. If we look big when standing in the room, we will feel small when we walk into the wilderness; If standing in the wilderness feels that the earth is huge, then standing in the universe, the earth is just a point. Therefore, those of us who live on the earth are insignificant to the whole universe. Space flight is a great science that makes us leave the earth. Its appearance not only satisfies our curiosity about the mysterious unknown field of the universe, but more importantly, it enables human beings to develop and utilize the resources of the universe, leaving more and more precious wealth for our descendants and making human species endless. China's space industry has reached a higher level in the world. The new rocket independently developed in China uses non-toxic and pollution-free propellant, which has the advantages of large thrust, low cost and high performance, and can be called "green" rocket. The progress of space technology will accelerate the progress of space technology in China and promote the development of many scientific fields in China. At the same time, it will also have a great impact on the improvement of China's comprehensive national strength and its position in the world. In the process of watching the space exhibition, what surprised me most was shenzhou spaceship's parachute. The parachute hung on the ceiling nearly ten meters from the ground, but it was still dragged to the ground. It is said that this parachute is 1200 square meters. That's it, taking the Shenzhou VI spacecraft's return capsule home, reducing the descending speed from180m per second to10m per second, that's it, crossing the hot atmosphere, blocking the high temperature and completely falling to the ground. Surprisingly, however, this parachute was sewn by hand. This reminds me of Meng Jiao's poem: "She sewed carefully, and she mended it thoroughly, fearing that the delay would make him come home late". The people of the motherland sew parachutes for space heroes, protect them from going home safely, and expect astronauts to return to the embrace of the motherland as soon as possible. These two moods are too similar. Another interesting thing is the food for astronauts. In the environment of weightlessness in space, food should not have too much juice or residue. In order to prevent food from floating around in the spacecraft cabin, space food needs to be processed into bite size, and the food packaged in metal should be able to withstand the test of impact, vibration and acceleration. Such a harsh requirement is to make delicious, fried rice, apples and even ice cream. Think about ice cream that doesn't freeze in the sun and can keep its original flavor. Isn't it amazing? I don't know much about aerospace, but a team that considers every detail is really desirable. I hope that one day, I can join the aerospace research.
