Analysis of Energy Demand and Technical Approach in Solar System Boundary Exploration

The exploration of the solar system boundary is of great scientific value and social significance to the heliospheric physics, interstellar space physics and the origin and evolution of the solar system, and has been highly concerned by various space research institutions in the world. Limited by long flight distance and long mission time, the solar system boundary probe needs to solve the energy technology problems of long life, high power and high reliability, which is one of the basic conditions and key technologies of the implementation of the solar system boundary emplacement exploration. On the basis of the study of ultra-remote earth surgery explorations at home and abroad and the demonstration of the marginal exploration mission in our solar system, the demands of the probe energy system were summarized, and the preliminary scheme of the energy system and the key technologies and technological difficulties were analyzed, which can provide reference for further demonstration of exploration missions.
