Abstract

The invention discloses a lunar surface water molecule and isotope composition in-place measuring system and method, and relates to a system and method for performing in-situ sampling extraction on lunar surface water ice in a lunar permanent shadow polar area and performing in-place water molecule content and isotope composition measuring by adopting a laser absorption spectrum-mass spectrum combination means. The system comprises an electric control unit, an analysis unit and a water ice extraction device, and is based on a lunar exploration landing platform. The method comprises the following steps: the landing platform lands in a to-be-measured area, an instrument is started for self-inspection, a water ice extraction device is heated to extract water vapor, an analyzer is started to measure the water content and hydrogen isotope, cooling is conducted to complete the analysis process of the area, moving to the next area is conducted, and finally measuring is completed.

Description

technical field [0001] The invention relates to a system and method for in-situ measurement of water molecules and isotope compositions on the lunar surface. Background technique [0002] The distribution, content and source of lunar water and volatiles are directly related to major issues such as the origin of the moon and the evolution of the magma ocean. At the same time, lunar water is also an important strategic resource, providing support for future lunar bases and manned lunar exploration activities. Therefore, it is of great scientific significance and strategic value to carry out lunar water ice detection. However, in the past, international lunar water ice detections all adopted remote sensing indirect technical solutions, including full-lunar neutron spectrum detection, imaging spectrometer, reflectivity detection, etc. At present, lunar water ice detection and isotope measurements have not been directly carried out in place, and this is the first time in our co...
