Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of high-fidelity simulation of lunar soil water ice material in the lunar permanent shadow area, and particularly relates to a lunar permanent shadow area ice-soil material formation and evolution mechanism simulation research device. BACKGROUND

[0002] Since the 21st century, humans have proven through remote sensing detection means that ice natural water exists in the lunar permanent shadow area at the north and south poles of the moon and exists in the form of ice-soil agglomerates in the lunar soil profile. Under the super-high vacuum conditions of the moon, why is there ice natural water? The scientific mechanism believes that it is due to the following three conditions: one is the extremely low temperature and lightless environment in the permanent shadow area, which provides the cold trap sublimation conditions for water material; two is the need for global thin water molecule injection flow; and three is the physical action of cold trap capture, absorption deposition and cold end migration between water molecules and lunar soil particles.

[0003] Planetary science and remote sensing detection evidence shows that the minimum temperature in the lunar permanent shadow area at the north and south poles of the moon can reach about 10-30 K, and the lunar atmospheric pressure is 10 -10 Pa order of magnitude, which is far beyond the research limit of the earth's permafrost and conventional water material science. Under the coupling conditions of low temperature and vacuum in the lunar permanent shadow area, complex physical actions such as cold trap capture, absorption deposition and cold end migration may occur between the global free diffusion of thin water molecules and lunar soil particles, and then ice-soil agglomerates are formed. Due to the limitation of deep space exploration capability, humans have not obtained on-site sampling and detailed evidence of lunar soil water ice material, and the formation and evolution mechanism of ice-soil material in the lunar permanent shadow area and the influence factors of environmental-material factors on the comprehensive properties of ice-soil agglomerates are not clear.

[0004] Facing the major needs of scientific detailed investigation, resource exploitation and utilization of ice-soil material in the lunar permanent shadow area, it is urgent to solve the basic problems of lunar soil water ice material simulation, lunar soil water ice comprehensive property testing and characterization. Looking at the technical status of countries around the world, lunar soil water ice material high-fidelity simulation is a worldwide problem. The current technical routes can be summarized into three categories: normal pressure water frozen ice, low temperature ice mixed soil and normal pressure vapor condensed ice, which can basically meet the envelope simulation and engineering verification of the harsh degree of lunar soil water ice mechanics, but the simulation material preparation method and process condition are not consistent with the scientific mechanism of the real formation and evolution mechanism of lunar soil water ice, resulting in a large gap between the thermal-electrical-optical-desorption properties of lunar soil water ice simulation material and the theoretical predicted value of real lunar soil water ice.
