It is reported that the research team finally decided to adopt a new composite material, which can meet the requirements of strength and dyeing performance, so as to ensure that the national flag can resist the harsh environment on the surface of the moon and does not fade, cross-color or deform.
Extended data
The national flag display system is only 1 kg:
Because the weight of the Chang 'e V national flag display system is only 1kg, the development team has made a lot of efforts to reduce the weight of the whole system, not only to reduce the materials, but also to "slim down" the equipment. Facing the harsh temperature difference environment on the surface of the moon, it also puts forward high requirements for the technological design and integrated design of the national flag display system.
When the national flag display system was established, the development team successively demonstrated the scheme of using four-pole, three-pole and two-pole as the national flag, but considering the complexity and weight, the two-pole was finally chosen to present it.
Li Yunfeng, head of the national flag display system project, said that the pole structure scheme was adopted because it is a relatively mature technology in the space system. The solar panels of spacecraft, including satellites and spaceships, are all deployed with pole structure, and its purpose is to ensure reliability.
A new vision of the northern night-the "cloth version" national flag unveiled by the moon is not simple! 1 years later, the materials were carefully selected and the test was more stringent.
