According to media reports, at 23:10 on December 3, 2020, after about 19 hours of lunar surface work, the Chang'e -5 probe of China's lunar exploration project successfully completed the lunar surface sampling, and the ascendant successfully took off with the lunar "local products" and embarked on a return voyage. Before takeoff, the five-star red flag carried by the lander successfully unfolded on the surface of the moon, and a touch of bright Chinese red excited and moved the world.

Unlike the national flags on Chang'e -3, Chang'e -4 and Yutu lunar rover, the national flag carried by Chang'e -5 is a real "fabric version" flag.
The five-star red flag on the moon is not as easy as imagined. Due to the strong electromagnetic radiation in the universe and the temperature difference of plus or minus 150 ℃ on the surface of the moon, if the national flag made of ordinary materials on the earth is exposed to the moon, it will immediately fade and cross color, and the flag surface will even break and decompose.

The National Space Administration announced the lunar exploration project Chang'e 5 probe on the lunar surface flag display photos.

In order to ensure that the first fabric national flag in China's space history can be successfully displayed on the moon, the scientific research team has gone through hardships to resist the harsh environment of the lunar surface, without fading, cross-color, and deformation.
The scientific research team selects the most advanced aramid production line with Yantai Taihe New Materials Co., Ltd., draws specialized technical forces, and uses special processes to produce high-performance aramid fiber materials. Taihe light for the selection of time more than 1 years. For dozens of selected fiber materials, through various physical tests such as thermal matching, high and low temperature resistance, anti-static, anti-moon dust, etc., it was finally decided to develop a new high-performance composite material; Wuhan Textile University in the research and development of fabrics, Using its "high-efficiency short-process embedded composite spinning technology", which won the first prize of national scientific and technological progress, a high-quality fiber material containing silk was developed. "During the first space environment simulation experiment in Beijing, the national flag had a red and yellow color problem." Cao Genyang, a member of the team, introduced that they also prepared micro-nano silk powder by using Xu Weilin's "ultra-fine powder of high-quality natural polymer materials and high-value-added reuse technology", which won the second prize of national scientific and technological invention, which essentially solved the problem of red and yellow color under extreme conditions and achieved a breakthrough in the core technical difficulties. At the same time, after more than a year of research, the team used small molecule control technology to put on a layer of protective clothing for silk powder, aramid and other materials. On the basis of protecting the color of the national flag, the technical problem of high dose ultraviolet radiation resistance was solved. Anhui Huamao Group adopted special production technology in the "one-stop" production process of spinning, weaving, dyeing and sewing to overcome the difficulties of spinning production and aimed at the low fiber coloring rate, invented to adapt to high and low temperature dyeing process, to solve the technical problems such as brilliance, viscosity, sewing flatness. Through the continuous efforts of the enterprise, the final success of the preparation of high-quality moon display flag fabric.
The successful application of the moon landing flag has added dazzling technological brilliance to the five-star red flag! The vast universe, the sky builds dreams, the China Industrial Textile Industry Association encourages member companies to adhere to innovative development, use new materials to help China's aerospace, and make greater contributions to the grand cause of mankind's exploration of the universe.
