Abstract

The study of volatiles and the search for water are the primary objectives of the Luna-27 mission, which is planned to land on the south pole of the Moon in 2028. Here we present the tunable Diode Laser Spectrometer (DLS-L) that will be onboard the lander. The DLS-L will perform isotopic analysis of volatiles that are pyrolytically evolved from regolith. This article dives into the design of the spectrometer and the characterisation of isotopic signature retrieval. We look forward to expanding our knowledge of Lunar geochemistry by measuring D/H, ¹⁸O/¹⁷O/¹⁶O, ¹³C/¹²C ratios in situ, which would be the one-of-a-kind direct study of the lunar soil isotopy without sample contamination.

月球-27 号着陆器上探索月球挥发物同位素的光谱仪

研究挥发物和寻找水是计划于 2028 年在月球南极着陆的月球-27 号任务的主要目标。在此，我们介绍将搭载在着陆器上的可调二极管激光光谱仪（DLS-L）。DLS-L将对从碎屑中热解出来的挥发物进行同位素分析。本文深入探讨了光谱仪的设计和同位素特征检索的特点。我们期待着通过现场测量 D/H、18O/17O/16O、13C/12C 比率来扩展我们的月球地球化学知识，这将是在没有样品污染的情况下对月球土壤同位素进行的独一无二的直接研究。
