| 火星原位资源利用指利用火星当地资源生产火星探测所需原料和能源，减少任务载荷，降低发射成本，是火星探测不可或缺的关键技术。金属和二氧化碳是火星重要的原位资源，部分金属可以在二氧化碳气氛中燃烧，使得金属/CO2燃烧体系在火星上扮演地球上化石燃料/空气燃烧体系的角色成为可能。从拓展金属/CO2燃烧技术在火星探测中应用的角度出发，梳理了火星二氧化碳收集方式、火星矿物分布和冶炼、金属/CO2燃烧技术的主要应用方式（Mg/CO2火箭发动机和Mg/CO2金属燃烧器）的研究进展，并对今后的研究进行了展望。 |

| Abstract: |
| In-situ resource utilization (ISRU) of Mars refers to the use of local resources of Mars to produce raw materials and energy needed for Mars exploration, to reduce mission load and launch costs, which is an indispensable key technology for Mars exploration. Metals and carbon dioxide are important in-situ resources on Mars. Some metals can be burned in carbon dioxide atmosphere, which makes it possible for metal/carbon dioxide combustion system to play the role of fossil fuel/air combustion system on Mars. From the point of view of expanding the application of metal/CO2 combustion technology in Mars exploration, this paper reviews the research progress of Mars carbon dioxide collection mode, Mars mineral distribution and smelting, and the main application modes of metal/CO2 combustion technology (Mg/CO2 rocket engine and Mg/CO2 metal burner), and prospects the future research. |
