Here we describe the novel, multi-point Comet Interceptor mission. It is dedicated to the exploration of a little-processed long-period comet, possibly entering the inner Solar System for the first time, or to encounter an interstellar object originating at another star. The objectives of the mission are to address the following questions: What are the surface composition, shape, morphology, and structure of the target object? What is the composition of the gas and dust in the coma, its connection to the nucleus, and the nature of its interaction with the solar wind? The mission was proposed to the European Space Agency in 2018, and formally adopted by the agency in June 2022, for launch in 2029 together with the Ariel mission. Comet Interceptor will take advantage of the opportunity presented by ESA's F-Class call for fast, flexible, low-cost missions to which it was proposed. The call required a launch to a halo orbit around the Sun-Earth L2 point. The mission can take advantage of this placement to wait for the discovery of a suitable comet reachable with its minimum V capability of . Comet Interceptor will be unique in encountering and studying, at a nominal closest approach distance of 1000 km, a comet that represents a near-pristine sample of material from the formation of the Solar System. It will also add a capability that no previous cometary mission has had, which is to deploy two sub-probes - B1, provided by the Japanese space agency, JAXA, and B2 - that will follow different trajectories through the coma. While the main probe passes at a nominal 1000 km distance, probes B1 and B2 will follow different chords through the coma at distances of 850 km and 400 km, respectively. The result will be unique, simultaneous, spatially resolved information of the 3-dimensional properties of the target comet and its interaction with the space environment. We present the mission's science background leading to these objectives, as well as an overview of the scientific instruments, mission design, and schedule.
在此，我们介绍新颖的多点彗星拦截器任务。该任务致力于探索一颗几乎未被研究过的长周期彗星，它可能首次进入内太阳系，或者遭遇一个源自另一颗恒星的星际物体。该任务的目标是解决以下问题：目标物体的表面成分、形状、形态和结构是什么？彗发中的气体和尘埃成分是什么，它与彗核的联系以及它与太阳风相互作用的性质是什么？该任务于2018年提交给欧洲航天局，并于2022年6月被该机构正式采纳，将于2029年与阿里尔任务一同发射。彗星拦截器将利用欧洲航天局F级快速、灵活、低成本任务征集所提供的机会，它就是针对该征集提议的。该征集要求发射到日地L2点的晕轨道。该任务可以利用这一位置等待发现一颗其最小速度能力可及的合适彗星。彗星拦截器将在以1000千米的标称最近接近距离遭遇并研究一颗代表太阳系形成时近乎原始物质样本的彗星方面独具特色。它还将具备一项以往彗星任务都没有的能力，即部署两个子探测器——由日本宇宙航空研究开发机构（JAXA）提供的B1和B2——它们将沿着不同轨迹穿过彗发。当主探测器以标称1000千米的距离飞过，探测器B1和B2将分别以850千米和400千米的距离沿着不同弦线穿过彗发。结果将是关于目标彗星三维特性及其与空间环境相互作用的独特、同步、空间分辨信息。我们介绍导致这些目标的任务科学背景，以及科学仪器、任务设计和时间表的概述。
