China's first Mars mission was named Tian Wen-1. Today is the fifth China Aerospace Day. The name and logo of China's first Mars exploration mission were announced at the launching ceremony of China Aerospace Day in 2022. 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 exploration missions were numbered in turn.
Why was it named Tian Wen? What do you mean? "Tian Wen" is the name of China's first Mars exploration mission and a long poem written by the romantic poet Qu Yuan. This poem is about Qu Yuan's exploration of the phenomena of heaven, earth, nature and the world. "At the beginning of ancient times, who preached? Facing the unknown world, Qu Yuan raised his own questions and expressed his persistent pursuit of truth.
From the origin of the universe to the integration of yin and yang; From the structure of heaven and earth to the trend of stars; From the darkness of heaven and earth to the change of the world; From the mountains and rivers of Kyushu to the lakes and seas in all directions; From the four seasons to the life and death of all things, Qu Yuan thought about the orbit of the sun, the period of the moon, the structural laws of celestial stars, the periodic changes of day and night, and the Big Dipper at the north and south poles, which are almost universally applicable.
Facing the questions of thousands of years ago, today's China is answering. Chang 'e-4 lander and lunar rover successfully completed the scientific exploration of the back of the moon for 16 months; A number of tasks, such as the launch of the Long March 5 remote three carrier rocket and the offshore technical test of China's first carrier rocket, are under way; Major projects such as high-resolution Earth observation system are under construction; High score, Beidou's accurate plotting and high-precision positioning in the anti-epidemic war. The Chinese nation's exploration of the stars and the sea has been on the road.
The symbol of the first Mars exploration mission, "Arriving at the Star in Nine Days", takes "China Planetary Exploration Project" as the overall concept, and the overall pattern is inclined upward, full of dynamic, flowing and upward impact, representing the spirit of "chasing dreams and being brave in exploration". The eight planets in the solar system are arranged in turn, and each planet presents its own characteristic color. Planets are embedded in C-shaped orbits, shining in the sky like diamonds, waiting for China people to pick the stars.
The open elliptical orbit forms the unique image of the letter "C", which contains three meanings. One is "China", which stands for "China" of planetary exploration; Second, "cooperation" represents the spirit of "win-win cooperation"; Three "c3", the most important physical quantities in planetary exploration engineering design, are important representations of the carrying capacity of deep space exploration and the ability of the probe to reach the extraterrestrial world.
The ancient people's exploration and the modern people's exploration echo the "heavenly question" from a distance. It is reported that the Mars probe will be launched this year to "orbit", "land" and "patrol" Mars, which is a milestone in China's space industry and a new starting point for our deep space exploration.
China Aerospace Day was launched in 2022 with the theme of "carrying forward the space spirit and embracing the sea of stars". This year, China Aerospace Day was also held online for the first time. The launching ceremony of China Aerospace Day in 2022 was held on the website of China National Space Administration and other online platforms. Fifty years ago today, China successfully launched the first man-made earth satellite "Dongfanghong-1". Over the past 50 years, under the strong leadership of the CPC Central Committee, the vast number of space workers have kept in mind their initial intentions, overcome difficulties and embarked on a unique road of self-reliance and independent innovation. "China Aerospace Day" originated from "Dongfanghong No.1". This year, with the theme of "carrying forward the space spirit and embracing the stars and the sea", I hope to encourage young people to set up lofty ideals, advocate exploration and creation, and realize the value of life through hard running. Encourage astronauts to gather their visions and goals, face risks and setbacks, and build a space power in constant struggle; Call on the whole society to persevere in the spirit of indomitable spirit, patriotism and dedication to pursue dreams, and unswervingly do something. On the basis of equality, mutual benefit, peaceful use and inclusive development, NASA is willing to make joint efforts with the international community to make new and greater contributions to exploring the mysteries of the universe and enhancing human welfare.
