Different five-star red flags

As the final battle of China's lunar exploration project, the launch mission of Chang 'e V was a complete success. After about 19 hours of lunar work, the lunar exploration project Chang 'e V successfully completed the automatic sampling of the lunar surface. 18 At 23: 00 on February 3, the elevator took off smoothly with the lunar "local products" and set foot on the return journey. Before the sampling task was completed, a "fabric version" of the five-star red flag carried by the lander was successfully deployed on the surface of the moon. This is the first time that China has realized the "independent display" of the national flag on the surface of the moon, which also marks the complete success of the lunar national flag display system. This is another successful demonstration on the surface of the moon after the perfect interaction between the Chang 'e III lander and the Yutu lunar rover on 20 13 15, and the China flag was brought to the back of the moon by the Chang 'e IV probe on 2018, which also made the China probe mark "China" on the moon again.

Can be displayed on the moon, the origin of this five-star red flag is not simple. The production team spent eight years developing this national flag. As far as material selection is concerned, the flag mainly adopts domestic high-performance aramid fiber materials, and adopts the "high-efficiency short-process embedded composite spinning technology" which won the first prize of national scientific and technological progress, thus overcoming the technical problem of preparing high-quality yarn from high-modulus differential fibers. With the support of this technology, the team successfully developed the moon display flag with A4 paper size and weight less than 12g, which is 40% lower than the weight required by aerospace.

As a national symbol, where the national flag is, the country is there. No matter how far away, no matter how high, when you see the national flag, you will see the motherland and your hometown. In fact, the five-star red flag, the national flag of People's Republic of China (PRC), was not born for a long time. From 1 year1October, when the first five-star red flag was raised in Tiananmen Square, until Chang 'e V planted the five-star red flag on the moon, only 7 1 year passed, which may be only a short moment in the history of human development, but it was in this short moment that the people of China created countless miracles, especially in the difficult year of 2020. In the face of "natural and man-made disasters", the pace of China's development is more firm. "I will never move." Throughout the year, China people are persevering and United: foreign trade, bravely facing economic hegemonism, and making every move; Resolutely win the battle against poverty and create a sense of happiness and gain for the broad masses of the people; Together, we stopped the COVID-19 epidemic and selflessly shared China's anti-epidemic experience with the world.

This year, we climbed Mount Everest again, planted a five-star red flag at the highest point of the earth, and re-measured the height of Mount Everest. This year, China made a major breakthrough in manned deep diving. Endeavour marks a new record for China to dive 10909 m in the deepest part of the world's oceans. This year, China astronauts successfully completed the Chang 'e-5 lunar exploration mission, and China's lunar exploration project took a solid step!
