Description

Technical Field

[0001] The present invention belongs to the technical field of high-realism simulation of lunar soil and water ice materials in the permanent shadow zone of the moon, and in particular to a device for simulation research on the formation and evolution mechanism of ice-soil materials in the permanent shadow zone of the moon. Background Art

[0002] Since the beginning of the 21st century, humans have proved through long-distance remote sensing that there is natural water in the permanent shadow areas at the north and south poles of the moon, and it exists in the lunar soil profile in the physical form of ice-soil aggregates. Why is there natural water in the ultra-high vacuum conditions of the moon? The scientific mechanism is believed to be due to the following three conditions: first, the extremely low temperature and no light environment in the permanent shadow area provide the cold trap condensation conditions for water substances; second, there must be a thin water molecule injection flow from the world; third, physical effects such as cold trap capture, adsorption deposition and cold end migration occur between water molecules and lunar soil particles.

[0003] Evidence from planetary science and remote sensing exploration shows that the lowest temperature in the permanent shadow areas at the north and south poles of the moon can reach about 10 to 30K, and the atmospheric pressure on the lunar surface is 10 -10 Pa level, such extreme low temperature and vacuum conditions far exceed the research limits of the earth's frozen soil and conventional water material science. Under the low temperature and vacuum coupling conditions in the permanent shadow area of ​​the moon, complex physical effects such as cold trap capture, adsorption deposition, and cold end migration may occur between the dilute water molecules from global free diffusion and the lunar soil particles, thus forming a stable ice-soil aggregate. Due to the limitations of deep space exploration capabilities, humans have not yet obtained field sampling and detailed investigation evidence of lunar soil water ice materials. The causes and evolution mechanisms of ice-soil materials in the permanent shadow area of ​​the moon, as well as the factors affecting the comprehensive physical properties of ice-soil aggregates by environmental-material factors, are still unclear.

[0004] In order to meet the major needs of scientific investigation, resource mining and utilization of ice-soil materials in the permanent shadow area of ​​the moon, it is urgent to solve basic problems such as simulation of lunar soil water ice materials, comprehensive physical property testing and characterization of lunar soil water ice. Looking at the technical status of countries around the world, high-fidelity simulation of lunar soil water ice materials is a global problem. The current technical routes can be summarized into three categories: normal pressure water frozen ice, low-temperature ice mixed soil, and normal pressure steam condensation ice. They can basically meet the envelope simulation and engineering verification of the harsh mechanical requirements of lunar soil water ice. However, the preparation method and process conditions of the simulant are less consistent with the scientific mechanism of the real formation and evolution mechanism of lunar soil water ice, resulting in a large gap between the physical properties of the lunar soil water ice simulant, such as thermal-electrical-optical-desorption characteristics, and the theoretical predicted values ​​of real lunar soil water ice. Summary of the invention

[0005] In view of this, the present invention aims to propose a simulated research device for the formation and evolution mechanism of ice-soil materials in the permanent shadow zone of the moon, so as to solve the problem that the existing preparation methods and process conditions of ice-soil material simulations in the permanent shadow zone of the moon are not in line with the scientific mechanism of the actual formation and evolution mechanism of lunar soil water ice, resulting in a large gap between the physical properties such as thermal-electrical-optical-desorption characteristics of lunar soil water ice simulations and the theoretical predicted values ​​of real lunar soil water ice.
