China's first Lunar probe "Chang'e 1" has a plan to complete four missions.
Chang'e 1's first mission is to obtain 3D images of the lunar surface. Its second task is to analyze the distribution of 14 useful elements and materials below the lunar surface. The third job of the lunar probe is to assess the thickness of the lunar soil and reserves of helium-3 resources. The fourth task is to explore the space environment 400,000 kilometers away from the moon, obtain data about solar winds, and study the impact of solar activity on the space environment between the earth and the moon.
