Abstract: Focusing on the requirements of scientific findings and Mars exploration mission innovations,and exploring advanced exploration modes,a novel scenario of Mars multi-mode combination exploration mission is proposed.Its characteristics rest with the combination of several exploration modes such as orbiting,landing,multi-point penetrating and ballooning,and consequently three-dimensional multi-layer and multi-source informationis obtained and scientific exploration is carried out in depth through one mission. Therefore,Mars can be exploredin three-dimensional multi-mode combinational ways,which not only develops the capability and technology for exploration activity but also helps to get a good grasp of Mars and heighten a comprehensive effect of exploration activity.The design results of multi-mode combination exploration not only apply to Mars exploration but also help to explore other extraterrestrial bodies such as Venus and Saturn.
