火星二氧化碳及水资源利用的研究进展

Progress in In-situ Resource Utilization of Atmospheric on Mars

摘要: 对于未来火星采样返回、载人火星探测任务而言，火星原位资源利用技术的研究具有必要性。在火星上提取并提前存储火星可用物资，可保障载人火星探测任务甚至火星殖民的需求。基于火星原位资源利用概念，对火星大气可利用的资源进行分析，分别从两大方面（二氧化碳资源和水资源利用）对国内外相关技术的发展情况进行分析，给出宇航员在火星活动和返回舱返回时，获取所需甲烷和氧气的方法。

Abstract: The technology of in-situ resource utilization (ISRU) on Mars is necessary for the future long-term missions such as Mars sampling return and manned Mars exploration.The extraction and the storage of available resources on Mars will guarantee the needs of the manned Mars mission and even Mars colonization.In this paper,based on the concept of Mars in-situ resource utilization,the available resources of Mars atmosphere is analyzed and the developments of related technologies at home and abroad from two aspects (H₂O and CO₂) are interpreted.Finally,the methods of obtaining the required methane and oxygen for astronaut activity on the Mars and return to the earth are given.
