Abstract: Mission planning of interplanetary multi objective flyby is carried out for solar system boundary exploration, and the optimization of low thrust interplanetary transfer orbit combined with planet gravity assistance is completed. Based on the above research, the interplanetary flight schemes for the exploration of the tip and tail of the heliosphere are given. The results show that a probe launched during 2024-2025 and 2027-2030 can arrive at about 100 AU from the solar center before 2049, and touch the nasal tip and tail of the heliosphere. Among them, the tip explorer is located in the central region of the nose tip when it flies to the distance of 100 AU, which can effectively complement the Voyager 1 and Voyager 2. The mission planning method used in this paper can provide the basis for the autonomous mission planning technology of solar system boundary exploration, and the relevant research results can provide valuable reference for the implementation of the first solar system boundary exploration mission in China in the future.
