火星液氧/甲烷推进剂原位制备技术研究进展

Review of In-Situ LOX/Methane Propellant Preparation on Mars

火星是人类深空探测的重要目标之一。利用火星上的大气、水等资源原位制备液氧、甲烷等推进剂,不仅为火星探测器返回地球、开展长周期火星探测等提供能源,也为人类建立火星生命保障系统提供必要的物质基础。分析了火星推进剂原位制备的重要性,对推进剂原位制备的资源、技术方案进行了对比分析,并重点叙述了CO_2捕集、水资源获取等方面的研究进展,以期为该领域相关研究提供参考。

Mars is an important target for human’s deep space exploration.Utilizing resources such as atmosphere and water on Mars to produce propellants such as liquid oxygen and methane could not only provide energy for Mars probe to return to earth and to carry out long term exploration on Mars,but also provide necessary material foundation for human to establish life support system on Mars.In order to provide references for domestic research on this area,the importance of in-situ propellant preparation on Mars,the available resources on Mars,and the differences between various methods of propellant preparation are analyzed.Furthermore,recent research ideas and achievements on CO2 capture and conversion and water acquisition,which are two main components of the propellant production system,are summarized in this review.
