Description

Technical Field

[0001] The present invention relates to the technical field of extraterrestrial exploration and resource development, and particularly to a microwave heating system and payload solution for extracting water resources from ice-containing lunar regolith. Background Art

[0002] In-situ acquisition and conversion utilization of water resources are key means to enhance deep space exploration capabilities. With the continuous development of remote sensing exploration technology on the surfaces of extraterrestrial celestial bodies, the evidence of the existence of water resources on the surfaces of the Moon, Mars, and near-Earth planets obtained by humans is becoming more and more sufficient. For example, foreign countries have used various detection means such as radar, neutron detectors, and spectrometers to confirm that a large amount of volatile resources such as water ice are stored in the polar regions of the Moon, and it is considered that water ice is most likely to be locally and dispersedly distributed in the range from the surface to a depth of several meters. On the surface of Mars, some orbital detectors (such as Mars Express and Mars Reconnaissance Orbiter) have confirmed the existence of water ice in the polar ice sheets through spectral analysis. Permanent ice caps composed of water ice and dry ice (solid carbon dioxide) exist at the North and South Poles of Mars. Currently, the direct evidence of water ice on the surface of asteroids is limited. The spectra of some carbonaceous asteroids show hydroxyl (-OH) absorption bands in the 3-micron wavelength band, indicating the existence of water ice or water-containing minerals (such as phyllosilicates) on or inside their surfaces. However, the occurrence form of water ice resources in lunar regolith is complex, and due to the extreme surface environment of extraterrestrial celestial bodies, involving high vacuum / low-pressure atmosphere, low / microgravity, low-temperature conditions, etc., it is difficult to in-situ mine and extract water ice resources.

[0003] Previous studies have proposed methods for heating lunar regolith and extracting water ice based on heat conduction, including methods such as direct heating of lunar regolith by solar concentrators and internal heating of drill tools. Since the distribution and occurrence position of water ice in lunar regolith are discrete, and the probability of containing water increases with depth, the existing surface heating methods have limited heat absorption range. Due to the small thermal conductivity of lunar regolith particles themselves, the efficiency of promoting the phase change sublimation (or evaporation) of water ice through heat conduction between particles is low, and the energy loss is large, etc., so the extraction rate and efficiency of water ice are both limited.
