Abstract

The Interstellar Mapping and Acceleration (IMAP) mission probes the interaction between our heliosphere and the interstellar medium (ISM) in unprecedented detail. The broad science that IMAP addresses has been organized into three distinct science themes: A) Acceleration and the broader context of the solar wind and space weather; B) Exploring the outer heliosphere through energetic neutral atoms, and C) Sampling of the interstellar and interplanetary material. This paper summarizes the scientific goals of the latter theme and identifies the key scientific opportunities for IMAP available due to its unique ability to directly sample the interstellar and interplanetary material from 1 au. It is organized into three broad scientific questions that directly relate to IMAP's science objectives: 1) What is the state of the pristine upstream LISM and how does it relate to its origins and evolution? 2) How does the VLISM interact with the heliosphere? 3) How does interstellar material, as well as interplanetary dust, affect the near-Sun environment?

用IMAP直接采样星际和行星际物质。

星际测绘和加速（IMAP）任务以前所未有的细节探测了我们的日球层和星际介质（ISM）之间的相互作用。IMAP所涉及的广泛科学被分为三个不同的科学主题：A)加速和太阳风和空间天气的更广泛背景；B)通过高能中性原子探索外日球层，C)星际和行星际物质取样。本文总结了后一个主题的科学目标，并确定了IMAP的关键科学机会，因为它具有直接从1au采集星际和行星际物质的独特能力。它被组织成与IMAP的科学目标直接相关的三个广泛的科学问题：1)上游原始LISM的状态是什么？它与它的起源和演变有什么关系？vism如何与日球层相互作用？3)星际物质以及行星际尘埃如何影响近日环境？

期刊介绍： Space Science Reviews (SSRv) stands as an international journal dedicated to scientific space research, offering a contemporary synthesis across various branches of space exploration. Emphasizing scientific outcomes and instruments, SSRv spans astrophysics, physics of planetary systems, solar physics, and the physics of magnetospheres & interplanetary matter. Beyond Topical Collections and invited Review Articles, Space Science Reviews welcomes unsolicited Review Articles and Special Communications. The latter encompass papers related to a prior topical volume/collection, report-type papers, or timely contributions addressing a robust combination of space science and technology. These papers succinctly summarize both the science and technology aspects of instruments or missions in a single publication.
