This article primarily explores a multi-energy complementary system for manned Mars bases. Rather than solely relying on nuclear energy, this system aims to ensure energy supply stability and sustainability for future Mars bases, energy for vehicular travel, and rocket fuel production using local in-situ resources on Mars. Through an in-depth analysis of the Martian environment, resources, and energy demands, combined with the latest energy technologies, we investigated multi-energy complementary solutions and technical pathways that integrate primary (e.g., solar and wind) and secondary (e.g., electrical and chemical) sources for energy consumption in Mars bases, exploration vehicles, and rocket fuel production using resources local to Mars. We designed and analyzed the Mars orbital solar power station in detail, an important component of the multi-energy complementary system. The power station harvests solar energy efficiently to convert it into electrical energy and supply it wirelessly to the Mars manned base. This solution effectively utilizes the abundant solar energy resources in the Mars orbit, while avoiding (i) direct construction of large-scale energy facilities on the Mars surface, (ii) and challenges such as, minimal electricity generation by solar photovoltaic panels at nights and due to coverage by Mars dust. We further examined the differences in the design and construction of the Mars orbital and Earth space solar power plants. The applicability of different types of energies (e.g., solar, wind, and potential chemical energy) was also evaluated for the Martian environment. Comparative analysis revealed the advantages of multi-energy complementary systems in improving energy utilization efficiency, enhancing system stability, and reducing single energy source dependence. Overall, the proposed multi-energy complementary energy system, especially with the application of the Mars orbital solar power station, provides a feasible energy solution for long-term large-scale manned missions on Mars, which is of great significance for promoting its exploration and colonization.
