Abstract: Four key technologies and solutions were summarized four key technologies and solutions: accurate prediction of water ice resources, scientific in-situ analysis, efficient extraction, and its transformation and utilization. For the demand of the detection and utilization of water ice resources in the polar regions of Moon, taking advantage of the deep low temperature and occurrence characteristics of water ice in the lunar polar regions, an integrated scheme of “Detecting, Mining and Utilization” on lunar water-ice resources was this paper proposed, and the application scenarios and functions, design plans and evaluations, application prospects, etc. The project provides technical reference and a scientific basis for future exploration, development and utilization of water ice resources in lunar polar regions, support for China’s fourth lunar exploration project and lunar scientific research station construction and other major missions.
