Where Is The New Moon Face National Flag? Academician Xu Weilin Of Wuhan Textile University Opened The "First Lesson" For Primary And Secondary School Students Across The Country

At 8:00 p.m. on September 1, the 2024 First Class, a public service program jointly sponsored by the Propaganda Department of the CPC Central Committee, the Ministry of Education and China Central Radio and Television Corporation, was broadcast on the CCTV comprehensive channel.

This year's First Lesson, with the theme of lovely China, invited experts in philology, history, wildlife rescuers, Olympic athletes, parachutists, captains of military transport aircraft, artificial intelligence experts, aerospace science and technology experts and other guests to show the ever-changing new look of the motherland by telling stories of self-improvement.

After more than an hour of the program, the host introduced the new progress of space science and technology: in June this year, after the successful landing of the Chang'e-6 probe on the back of the moon, a bright red flag with five stars was launched, which is the first time that China has independently and dynamically displayed the national flag on the back of the moon. How is this national flag made? Xu Weilin, academician of the Chinese Academy of Engineering and president of Wuhan Textile University, stepped onto the platform and revealed the secrets on the spot.

Xu Weilin brought the same backup version of the national flag as on the moon, attracting children to rush to touch it. "It feels strong!" "It's too thick!"

"There is no wind or rain on the moon, but the ultraviolet ray is very strong." Xu Weilin said that the temperature difference between the height of the moon and the height of the moon reaches 300 ℃, and the general fabric cannot withstand the extreme environment of the moon. Basalt is the main component of the lunar soil. The team decided to use basalt as the material for making the national flag.

In order to meet the performance requirements, the basalt wire should be very thin. How thin? The answer is 5.5 microns, close to one tenth of the hair. Academician Xu said that the team spent half a year to conquer basalt wire drawing, and then spent about two years to spin basalt fiber into yarn and weave it into a cloth with dense structure.

Basalt is acid and alkali resistant, high temperature resistant, corrosion resistant, and is abundant on the moon. Xu Weilin imagines; "In the future, we can take basalt to make clothes for the moon and build houses on the moon!"

"I hope to replicate a China on the earth on the moon in the future!" After listening to the academicians, Shen Zixia, a sixth grader of Wuhan Hongshan Experimental Foreign Language Primary School, was very excited. In the new semester, he would study harder and acquire rich knowledge, hoping to explore the possibility of the moon when he grew up, "In the future, we can all have a home on the moon. We can go to the moon to live there, reduce the burden of the earth, and let the beautiful earth have its own 'holidays'!"

Wang Ziyihao, a seventh grader at Wuhan American Canadian Foreign Language School, watches the First Lesson every year. This year, he becomes a junior high school student and will start a new learning stage.

"Difficult" earth digging "sampling on the moon, basalt materials making the national flag fly on the back of the moon, and simulating the moon soil burning bricks to build houses... These achievements have made me deeply proud of the strength of the country!" Wang Ziyihao was encouraged. He said that in the new semester, he should carry his dream, march forward bravely, and contribute his own strength to the prosperity of the motherland in the future.
