Landing on the back of the moon is of great significance. First of all, the probe that landed on the back of the moon will get many unique scientific research achievements, which will be a great contribution to world space and astronomy. The back of the moon is a crater that is extremely difficult to land. There are many craters on the back of the moon, especially in the Antarctic-aitken basin, where the topography and elevation map are extremely complex, and a large number of systems with landing sensors are needed. Von Kamen Crater belongs to one of the core areas, and for Chang 'e IV, it is equivalent to going over mountains and mountains.
In addition, international cooperation has been strengthened. There are many international organizations on the rocket fairing of Chang 'e IV mission. It can be seen that this mission is highly international. In science, the low-frequency electric detector cooperates with the Netherlands, the lunar neutron and radiation dose detector cooperates with Germany, the neutral atom detector cooperates with Sweden, and the lunar small optical imaging detector cooperates with Saudi Arabia. Therefore, this is also a major breakthrough in international cooperation.
