A detailed overview of the knowledge gaps in our understanding of the heliospheric interaction with the largely unexplored Very Local Interstellar Medium (VLISM) are provided along with predictions of with the scientific discoveries that await. The new measurements required to make progress in this expanding frontier of space physics are discussed and include in-situ plasma and pick-up ion measurements throughout the heliosheath, direct sampling of the VLISM properties such as elemental and isotopic composition, densities, flows, and temperatures of neutral gas, dust and plasma, and remote energetic neutral atom (ENA) and Lyman-alpha (LYA) imaging from vantage points that can uniquely discern the heliospheric shape and bring new information on the interaction with interstellar hydrogen. The implementation of a pragmatic Interstellar Probe mission with a nominal design life to reach 375 Astronomical Units (au) with likely operation out to 550 au are reported as a result of a 4-year NASA funded mission study.
本文提供了对日球层与基本上未被探索的本地星际介质（VLISM）相互作用方面知识空白的详细概述，并对即将到来的科学发现进行了预测。文中讨论了在这个不断扩展的空间物理学前沿取得进展所需的新测量方法，包括在整个日鞘进行原位等离子体和拾取离子测量、对VLISM特性（如元素和同位素组成、中性气体、尘埃和等离子体的密度、流动和温度）进行直接采样，以及从能够独特辨别日球层形状并带来与星际氢相互作用新信息的有利位置进行远程高能中性原子（ENA）和莱曼阿尔法（LYA）成像。作为美国国家航空航天局（NASA）一项为期4年的资助任务研究的结果，报告了一个务实的星际探测器任务的实施情况，该任务的标称设计寿命是到达375天文单位（au），可能运行到550 au。
