Abstract

月球极区水冰探测对揭示月球演化、支撑未来月球科研站建设至关重要. 然而, 通过现有遥感手段与返回样品难以精确获取其赋存形态、含量及来源. 嫦娥七号( Chang’E-7 )飞跃器将搭载月壤水分子分析仪(LUWA), 首次对月球南极永久阴影区水冰开展就位探测. 本文介绍了LUWA的组成、原理及其与水冰钻取装置协同实现“钻探采样－接样密封－加热分析”的探测过程. 为确保载荷在轨实现高灵敏度、宽动态范围的水冰含量探测和高精度水同位素分析, 针对三个测水功能模块搭建了地面定标试验装置, 提出了定标方法; 围绕整机性能指标, 搭建了月壤水冰就位探测模拟试验平台, 模拟极区水冰的钻采、接样、密封、加热与分析全过程, 为在轨月壤水冰含量等数据反演提供重要支撑.
