摘　　要：来自太阳系边际及以外的星际空间的能量中性原子,是认识邻近星际介质及其与太阳风相互作用的重要载体。受限于太阳系边际就位探测的任务时长与探测难度,在近地空间对日球层边际能量中性原子实施遥感探测更为切实可行。研究日球层边际能量中性原子可以增进对局地/邻近星际介质的组成及性质了解,深入验证太阳系演化与系内行星演变过程等空间科学问题,对推动我国空间任务和前沿科学发展有着重大意义。本文对近年来国际上开展或计划开展的日球层边际能量中性原子遥感探测的案例进行了总结,分析其探测任务的关键技术与科学目标,梳理了未来该领域的发展趋势及方向,针对我国今后的太阳系边际探测任务规划与技术发展提出了建议。Energetic neutral atoms from the solar system's heliopause and beyond serve as important carriers for understanding the neighboring interstellar medium and its interaction with the solar wind.Due to the limited duration and difficulty of missions to the heliospheric boundary of the solar system,remote sensing detection of energetic neutral atoms in the near-Earth space is more feasible.Studying energetic neutral atoms at the heliospheric boundary can enhance our understanding of the composition and properties of the local or nearby interstellar medium,thoroughly verify space science questions such as solar system evolution and planetary evolution in the solar system,and has significant implications for advancing China's space missions and frontier scientific development.This paper summarizes recent international cases of remote sensing detection of energetic neutral atoms at the heliospheric boundary,analyzes the key technologies and scientific objectives of these missions,and outlines the future trends and directions in this field,providing suggestions for the planning and construction of future heliospheric boundary exploration mission in China.
