The five-star red flag carried by Chang'e 6 was successfully unfolded on the back of the moon. This is also the first time that China has independently and dynamically displayed the national flag on the back of the moon.
How is the five-star red flag shining on the moon made? What are its characteristics? Let's follow the CCTV reporter to uncover the secrets.
CCTV reporter Cui Xia: This is the Beijing Aerospace Flight Control Center. What you see on the big screen is a photo of Chang'e 6 displaying the national flag on the lunar surface. This national flag is made of special materials. In the photo, the national flag in the hands of Chang'e 6 shows a bright Chinese red under the sunlight.
Zhou Changyi, researcher at the National Space Science Center of the Chinese Academy of Sciences and chief designer of the payload subsystem of the Chang'e 6 probe: The national flag can inspire the patriotic enthusiasm of Chinese people around the world. I think people all over the country are looking forward to this picture and are proud of our great motherland.
The national flag displayed by Chang'e 6 was made by scientific researchers after more than a year of research using basalt melt drawing technology. It has stronger corrosion resistance, high temperature resistance, low temperature resistance and other excellent properties.
Zhou Changyi, researcher at the National Space Science Center of the Chinese Academy of Sciences and chief designer of the payload subsystem of the Chang'e 6 probe: The basalt stone comes from Weixian County, Hebei Province. After the basalt is transported back, it must be crushed and melted and pulled into filaments about one-third the diameter of a hair, and then spun into thread and woven into cloth. Because the basalt content on the moon is abundant, when we build a lunar base in the future, we will most likely have to make basalt into fibers and building materials.
