Prospects and Ideas on the Simulation of the Fabric Feature of Lunar Icy Regolith and the Test of Its Mechanical Properties
With the technology development of deep space exploration,lunar icy regolith has gradually become a hot spot and focus of the exploration of extraterrestrial objects.Recent years,many countries have started in-situ detections of lunar icy regolith profiles,which makes it an urgent need to simulate the characteristics of water ice fabric and study its mechanical characteristics.However,there are obvious Earth-Moon differences between lunar icy regolith and frozen soil on the Earth,especially in its origin,evolution mechanism,occurrence form and distribution.The history of water ice exploration is first summarized.And the research progress of lunar icy regolith fabric simulation and its mechanical characteristics studies at home and abroad are introduced.The target characteristics of material is analyzed with emphasis,and the future development trend of lunar icy regolith fabric simulation and its mechanical characteristics study are predicted finally.Four key technical problems that need to be solved in the future research are put forward,and the corresponding research ideas are given.Finally,the current research problems and prospects for development and application of water ice fabric characteristics simulation and its mechanical properties test are summarized and prospected.
