摘要
在月表开展探测活动时,宇航员和设备的操作导致扬尘浓度远远高于自然状态下的扬尘。带电的月尘颗粒不仅会影响航天设备性能,其高度的磨损性和生物毒性还会对宇航员的健康构成严重威胁。为系统性地了解月尘污染,本文首先介绍了月尘的物理、化学特性和带电特性,以便深入了解其污染行为的本质。其次总结以往探月任务中的月尘污染问题,详细分析了这种污染对探月设备各系统的危害。最后调研了已有月尘防控方案,评估了其优缺点、适用场景以及未来的发展方向,特别是对以电磁力为主的多种防尘除尘技术进行了详细分析。未来的研究将侧重于电场主动防尘与除尘关键技术在模拟月球环境中的应用,以确保月球探测活动的顺利进行和宇航员的健康安全。
During lunar surface exploration activities,the operations of astronauts and equipment significantly elevate dust concentrations beyond natural levels.These charged lunar dust particles not only affect the performance of space equipment but also pose serious health threats to astronauts due to their high abrasiveness and biotoxicity.To systematically understand lunar dust contamination,we first reviewed the physicochemical and electrical properties of lunar dust to gain insights into its contaminating behavior.By summarizing the dust-related issues encountered in previous lunar missions,we provided a detailed analysis of the impact of this contamination on various systems of lunar exploration equipment.Finally,we examined existing lunar dust mitigation strategies,evaluating their strengths,weaknesses,suitable scenarios,and future development directions,with a focus on dust prevention and removal technologies that primarily utilize electromagnetic forces.Future research will concentrate on in-depth investigations of key technologies for active dust prevention and removal through electric fields in simulated lunar environments,ensuring the smooth progress of lunar exploration activities and safeguarding the health and safety of astronauts.
