Chang'e and Jade Rabbit set on the moon

Chang'e-3 is the second stage of China's three-step lunar exploration strategy of "orbiting, landing, and returning", achieving China's first direct landing on the moon. As the leading mission of the fourth phase of the lunar exploration project, Chang'e-4 opened the curtain of the fourth phase of the lunar exploration project and achieved the world's first landing on the far side of the moon. The scientific payload on the Chang'e-4 lander can conduct low-frequency radio astronomical observations on the far side of the moon, detecting the cosmic ray radiation on the lunar surface; The scientific payload on the rover can explore and study the surface structure, topography, and mineral composition of the moon. The goal of this mission is to explore the topography, geological structure, mineral and chemical composition of the lunar surface, the internal structure of the moon, the Earth Moon space environment, and to conduct detailed research on the far side of the moon, especially the Aitken Basin. Chang'e-4 also attempted relay communication on the far side of the moon and conducted the first low-frequency radio astronomical observation. These tasks not only deepen our understanding of the geological structure and evolution of the far side of the moon, but also.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Chang'e-3 and Chang'e-4 are the second steps of the Chang'e project, achieving China's first extraterrestrial landing and the world's first lunar landing. The Chang'e-4 mission mainly includes two parts: the lunar lander and the rover on the far side of the moon. The lander is equipped with multiple scientific instruments for studying information on rocks, structures, and minerals on the surface of the moon. The rover is used to detect changes on the surface of the moon and observe cosmic rays. The main mission objectives of Chang'e-4 include carrying out exploration activities on the lunar surface topography, geological structure, mineral composition and chemical composition, internal structure of the moon, lunar space and lunar surface environment, and building a basic supporting lunar exploration engineering system; Explore the far side of the moon, especially the largest known meteorite craters in the solar system; Attempt relay communication on the far side of the moon; Conduct the world's first low-frequency radio astronomical observation. This mission is of great significance for gaining a deeper understanding of the geological structure, mineral composition, and formation and evolution of the far side of the moon.
