Viewing the Chinese nation's space dream and spirit from Tian Wen

At the launching ceremony of China Aerospace Day 2020 held on April 24th, the name and mission logo of China's first Mars exploration mission were officially announced. China's planetary exploration mission was named "Tian Wen Series", the first Mars exploration mission was named "Tian Wen No.1", and the subsequent planetary missions were numbered in turn.

Tian Wen, which comes from Songs of the South, imagines and questions everything from the origin of the universe to the integration of Yin and Yang. From the structure of heaven and earth to stars. Taking "Tian Wen" as the project name is deeply rooted in the essence of China traditional culture, which is easy to be accepted by the masses, easy to remember and spread. It also shows the determination and perseverance of Chinese people to go further into deep space, and guides the public, especially teenagers, to establish their ideal feelings of loving and advocating science. Expressed the tenacity and persistence of the Chinese nation in pursuing truth; It embodies the cultural inheritance of natural and cosmic space exploration; It means that the pursuit of scientific truth is long and the pursuit of scientific and technological innovation is endless.

Facing the vast universe, the Chinese nation has never lacked imagination, let alone the determination and ability to understand the universe. Looking back at history, the practical activities of the Chinese nation from ignorance to civilization are exactly the course of our exploration and yearning for the starry sky in the universe.

Shangshu is one of the oldest relics of China culture. When we open this book, the highlight is the cognition and exploration of Chinese ancestors on the starry sky. After Yao, one of the ancestors of the Chinese nation's humanities, came to power, he ordered Xihe and Heshibi to "learn from the sun, the moon and the stars and respect people", that is, to understand the operation of the sun, the moon and the stars, make a calendar, and tell the people all over the world to live and produce according to the scientific laws of the universe. In order to accomplish this task, he appointed Xi Zhong, Uncle Xi Zhong and Uncle He Zhong to be stationed in the southeast, northwest and northwest directions respectively to observe and record the movement of the sun, moon and stars in all directions. The four of them established the vernal equinox, summer solstice, autumn equinox and winter solstice, and set a year as 366 days, divided into 12 months, with 29 or 30 days in each month, which solved the time difference problem in the form of four years plus a leap month, and its accuracy surprised scientists today.

"Huainanzi" said, "I invited the Queen Mother of the West, a fairy medicine, and my wife Chang 'e stole the moon, committing herself to the moon as a toad and the essence of the moon. "the Goddess Chang'e flying to the moon" is a myth that Chinese people worship and yearn for the stars since ancient times.

Do you know the Wanhu Mountain on the moon? At the end of the Ming Dynasty, about14th century, there was an official named Wan Hu who put the largest 47 rockets that could be bought at that time on the back of a seat. He tied himself to a chair and held a big kite in one hand. Naturally, he asked his servant to light 47 rockets at the same time, hoping to fly forward with the help of the power of rockets and the rising power of kites. Unfortunately, the rocket exploded and thousands of families gave their lives for it. In order to commemorate "the first man who tried to fly by rocket", a crater on the moon was named "Wan Hu" at an International Astronomical Union in 1970s. Wan Hu was the first pioneer of manned rocket flight and the first person to "fly". This is the spirit of the Chinese nation to explore the universe and space, even at the cost of life.

Time flies, the revolutionary ancestors washed away the backwardness and shame of modern China. Time is up 1970. On April 24th, the Long March-1 carrier rocket was launched at 2 1: 35, and the satellite entered the scheduled orbit at 2 1: 45. Dongfanghong music resounded through space and shocked the world. When the music of "Dongfanghong" sounded in space, it marked that modern China officially opened the space age. China astronauts live up to expectations!

Over the past 50 years, from "Dongfanghong" 1 to "Tianwen" 1, which will be launched soon, China astronauts have forged a manned space spirit that is particularly hard-working, especially capable of fighting, especially tackling key problems, and especially dedicated.

Yang Liwei, Fei, Nie Haisheng, Zhai Zhigang, Liu Boming, Jing Haipeng, Liu Wang, Zhang, Liu Yang and Wang Yaping are all favored by the Air Force. Their flight time ranges from 800 hours to 2000 hours. They have made a lot of contributions in the Air Force, and they are all excellent talents who have been selected at different levels.

Great cause produces great spirit. In the struggle for the cause of "two bombs and one satellite", the vast number of developers have cultivated and carried forward a lofty spirit, which is the national spirit of "two bombs and one satellite" of "loving the motherland, selfless dedication, self-reliance, hard struggle, great cooperation and courage to climb". The chief designers of various spacecraft look up at the starry sky with their feet on the ground. The older generation of scientists and researchers carried forward the spirit of "loving the motherland, selfless dedication, self-reliance, hard struggle, strong cooperation, and courage to climb", camped out in the wind, fought hard, and cooperated in unity, overcoming all kinds of unimaginable difficulties and obstacles, breaking through one technical difficulty after another, and achieving great achievements that the Chinese nation is proud of. Scientists Qian Xuesen, Qian Sanqiang, Ren Xinmin, Wang and shenzhou spaceship's chief designer Qi Faren Zhang Bainan perfectly interpreted the spirit of "two bombs and one satellite".

Over the past decades, the Chinese nation has possessed the manned space spirit of being particularly capable of fighting, tackling key problems and contributing, as well as the spirit of loving the motherland, selfless dedication, self-reliance, hard struggle, great cooperation and courage to climb. China has made great achievements in manned space flight one after another! Long March rocket, Dongfanghong 1, Shenzhou manned spacecraft, Tiangong space station, Chang 'e lunar probe, Yutu lunar rover, Beidou navigation satellite, the question mark is coming soon. China's space industry has brought us unparalleled achievements and national pride.

German philosopher Hegel said: A nation should have a group of people who look up at the stars. I hope that the teenagers present here will look up at the stars on the premise of being down to earth. Looking up at the stars is to have an aerospace dream; Down-to-earth is to learn space knowledge.

Our aerospace industry is a great cause, our astronauts are a group of great people, and our motherland is a great country!
