As the nearest celestial body to the earth, the moon is the first stop for mankind to open the "interstellar era". This year, China will comprehensively promote the fourth phase of the lunar exploration project, including Chang'e 6, Chang'e 7 and Chang'e 8 missions. Wu Weiren, chief designer of China's lunar exploration project, said that Chang'e VI would collect more samples from the back of the moon to achieve the goal of 2000 grams. Chang'e 7 is preparing to land at the south pole of the moon. Its main task is to carry out leaping exploration and try to find water. Chang'e 8 will be launched around 2028. Chang'e 7 and Chang'e 8 will form the basic model of the lunar Antarctic scientific research station, including the lunar orbiter, lander, lunar rover, jumper and several scientific exploration instruments.
