Preparation and experimental study of aqueous simulated lunar soil in lunar polar region

The polar region of the Moon has great scientific value and research significance because of abundant mineral resources, possible water and ice and unique geographical location resources, and is becoming a new hot spot in the new round of international lunar exploration. China?s Chang ?e-7 probe will also go to the polar region of the Moon carry out the sampling and detection mission of water-bearing lunar soil. In this paper, a set of water-bearing simulated lunar soil preparation system in polar regions is proposed, and the preparation and research of water-bearing simulated lunar soil in polar regions are carried out from several aspects, such as preparation of water-bearing simulated lunar soil, research and development of vacuum system, design of simulated lunar soil bucket and vacuum test. The test results show that the water-bearing simulated lunar soil developed by the system has no abnormal situation in vacuum environment, and can be applied to the subsequent ground test of Chang ?e-7 detector
