The naming method of space equipment is closely related to the characteristics of the times and is the product of the characteristics of the times. In the early days of China's space industry development, the international situation was tense, and most space projects were led by the military. The purpose of project establishment was often to catch up with the Soviet Union and surpass the United States. The name of aerospace engineering, which bears the heavy responsibility of national defense and the significance of national image engineering, should not be based on romance, but should reflect the values of China at that time. For example, the Long March rocket series, which still undertakes the carrying mission today, was named after the chairman's poem "Seven Laws and the Long March" adapted by the space pioneer in the 1960s. The upper stage of the Long March rocket, that is, the last stage is responsible for putting the equipment into orbit. It also quotes the famous sentence "The Red Army is not afraid of the expedition, and Qianshan is just idle", which continues the fine tradition of our party and army and also indicates that China's space industry is not afraid of the expedition.
Now China's economic development is in good condition, and astronaut idolize's concept of promoting traditional culture is more and more deeply rooted in people's hearts. Today, the average age of China's R&D team is very young: the aircraft carrier team is 37 years old, the quantum physics team is 35 years old, the Big Dipper is 33 years old, and the C9 19 aircraft team is 28 years old. The aerospace field is no exception. The average age of teams such as Tian Yan and Tiangong is only about 30 years old. The age structure of astronauts is getting younger and younger, and their lives have been far away from that special era in the past. The romantic color of the idolize sea possessed by astronauts was aroused. Reflected in the China spacecraft, there are more romantic names, which make people think.
The code name "Chang 'e" of the moon landing plan is full of mythical significance. The moon probe Yutu II released by Chang 'e IV made the myth really shine into reality. In addition to the name, the symbol of the Chang 'e Project is also full of implications: the whole word "Moon" is written in the style of China's calligraphy, the blue crescent represents the moon, and the two sides in the middle are represented by a pair of footprints, which symbolizes the ultimate dream of China people to land on the moon. The blue crescent moon looks like a faucet from the end of the pen, representing China; The flying white at the tail of the new moon is composed of doves of peace, which expresses China's good wishes for the peaceful development of space.
