Abstract: Solar system boundary exploration is of great significance to obtaining important scientific discoveries, promoting strategic and forward-looking technological breakthroughs, and enhancing human space exploration capabilities. On the basis of introducing the definition and future plans of Solar system boundary exploration missions, this paper analyzed the mission characteristics, studied the current mission requirements and technical challenges, and systematically discussed artificial intelligence technologies that need to be broken through, including intelligent processing of exploration data, intelligent perception of environment, event and state and control, intelligent planning of exploration missions, and lightweight and reliable intelligent algorithms. This paper can provide reference for the planning, demonstration, development, and implementation of Chinese Solar system boundary exploration missions.
