On April 24, 2020, the National Space Administration announced that China's planetary exploration project was named "Tianwen Series", and the first Mars exploration mission was named "Tianwen I". At 12:41 on July 23 of the same year, China's new generation of high thrust carrier rocket, Long March 5, lifted the "Tianwen 1" probe into the sky and headed for Mars.
At 7:18 on May 15, 2021, "Tianwen 1" successfully landed on the Martian Utopia Plain. This is a key step for the Chinese people to explore the universe, and the official gave high praise to this exploration activity: "The mission of" Tianwen 1 "broke through the key technologies such as the second cosmic speed launch, interplanetary flight and TT&C communication, and soft landing of extraterrestrial planets, and achieved the first landing of extraterrestrial planets in China, which is another milestone of great significance in the development of China's aerospace industry." To achieve this goal, it is very difficult to face many tests of harsh natural conditions: "Mars exploration is risky and difficult. The exploration mission faces challenges such as the interplanetary space environment, the thin atmosphere of Mars, and the fire surface topography. At the same time, affected by long distance and long time delay, the landing phase has difficulties such as uncertain environment, complex landing procedures, and no ground intervention."
On November 8, 2021, good news came from "Tianwen No.1". The Lunar Exploration and Space Engineering Center of the National Space Administration released the news: "The 'Tianwen 1' orbiter successfully implemented the fifth near fire braking, accurately entered the orbit of the remote sensing mission, and carried out global remote sensing exploration of Mars." The People's Daily recorded this important historical moment: "Up to now, the orbiter has been in orbit for 473 days, with a distance of 384 million kilometers and a light travel time of 21 minutes and 20 seconds; The rover has worked on the Martian surface for 174 Martian days, and has driven 1253 meters in total. The two rovers are in good condition, and the working conditions of each system are normal. "
Many people are interested in the name "Tianwen". What does it mean? According to the introduction: "The name originates from Qu Yuan's long poem" Tianwen ", which expresses the Chinese nation's tenacity and perseverance in the pursuit of truth, reflects the cultural heritage of the exploration of nature and space, and implies that the journey to explore scientific truth is long, and the pursuit of scientific innovation is endless." It can be seen that the name of "Tianwen" connects the ancient and modern, and the spirit of exploring the unknown, It has been accompanied by the development of Chinese culture.
The history and culture behind the name "Tianwen" is very interesting. Since its birth, it has demonstrated the world's interest in exploring the unknown. This is not only a sigh of thousands of years for us to pursue the mysteries of the universe, but also an unremitting effort to explore the infinite.
