标题： Voyager 3: A Concept Mission to Interstellar Medium

摘要： 旅行者3号是一个概念任务，它在合理的时间内将一个空间望远镜发送到星际介质中。 旅行者3号将在550天文单位（AU）的距离处利用太阳的引力透镜效应，直接拍摄一颗系外行星的图像。 航天器将使用其科学仪器套件来研究本地太阳系和星际介质的环境，并通过拍摄系外行星完成其主要任务。 提出了两种潜在的架构来满足这一任务指令，使用多次引力辅助和大功率电推进燃烧以达到必要的高速逃逸速度，从而到达550 AU。 本文扩展了科学任务目标、轨迹以及基准航天器的初步设计。 显示英文摘要

摘要： Voyager 3 is a concept mission that sends a space telescope to the interstellar medium in a reasonable amount of time. Voyager 3 would take a direct image of an exoplanet using the solar gravitational lensing at the distance of 550 astronomical unit (AU). The spacecraft would use its suite of scientific instruments to study the environment of the local solar system and interstellar medium and finalize its primary mission by imaging an exoplanet. Two potential architectures are proposed to meet this mission directive, using multiple gravitational assists and sizable electric propulsion burns to achieve the high escape speeds necessary to reach 550 AU. This paper expands on the science mission objectives, trajectory, and the preliminary design of the baseline spacecraft.
