Progress and Key Challenges of Lunar Resource Exploration and In-situ Utilization
Lunar construction(LC)is one of the important future directions of human exploration,utilization,and development of the Moon.This paper reviews the research progress of LC and in-situ resource utilization(ISRU),focusing on the key basic science issues including what materials to use and how to build.First,the main supporting technologies for ISRU on the lunar surface are summarized,including lunar soil property analysis,lunar soil simulant preparation,and lunar soil in-situ additive manufacturing technologies.Second,the progress of the intelligent construction of the lunar base is introduced,including the development of the lunar base construction scheme,the comparison of in-situ construction technology,and the analysis of the lunar base construction environment.Finally,the key scientific challenges of LC and ISRU are discussed,including resource exploration,scientific site selection,lunar base bearing safety,lunar soil melting and sintering,and space construction schemes.
