含冰模拟月壤水资源提取实验研究

地外水资源不仅可以确保人类在地外的生存，还能够通过光化学反应分解生成H2为火箭补给燃料，是原位资源利用的关键物质资源。文章首先对地外水资源的探测情况以及提取方法研究现状进行综述，然后基于提出的水资源提取新方法搭建了含冰模拟月壤水提取实验装置，并以CUG-1A模拟月壤为原料开展了初步的实验研究。结果显示：对于初始含冰量10%、初始温度-15 ℃的含冰模拟月壤，在500 W加热功率下，1 h之后收集到的冷凝水量为15 g。

Experimental study of water resource extraction from frozen lunar regolith simulants

The water resource is essential for the extraterrestrial in-situ resource utilization, and it can not only ensure the human survival in space but also refuel the rocket with hydrogen by the photochemical reaction. In this paper, the explorations and the methods for extracting the extraterrestrial water resources are reviewed firstly; then an apparatus is built based on the proposed novel water extraction method, and a preliminary study is conducted with the lunar regolith simulant CUG-1A. It is shown that the mass of the collected condensate reaches 15 g after one hour with a heating power of 500 W when the initial ice content of the frozen lunar regolith simulants is 10% and the initial temperature is -15 ℃.
