The Mapping Imaging Spectrometer for Europa (MISE) is an infrared compositional instrument that will fly on NASA's Europa Clipper mission to the Jupiter system. MISE is designed to meet the Level-1 science requirements related to the mission's composition science objective to "understand the habitability of Europa's ocean through composition and chemistry" and to contribute to the geology science and ice shell and ocean objectives, thereby helping Europa Clipper achieve its mission goal to "explore Europa to investigate its habitability." MISE has a mass of 65 kg and uses an energy per flyby of 75.2 W-h. MISE will detect illumination from 0.8 to 5 μm with 10 nm spectral resolution, a spatial sampling of 25 m per pixel at 100 km altitude, and 300 cross-track pixels, enabling discrimination among the two principal states of water ice on Europa, identification of the main non-ice components of interest: salts, acids, and organics, and detection of trace materials as well as some thermal signatures. Furthermore, the spatial resolution and global coverage that MISE will achieve will be complemented by the higher spectral resolution of some Earth-based assets. MISE, combined with observations collected by the rest of the Europa Clipper payload, will enable significant advances in our understanding of how the large-scale structure of Europa's surface is shaped by geological processes and inform our understanding of the surface at microscale. This paper describes the planned MISE science investigations, instrument design, concept of operations, and data products.
木卫二测绘成像光谱仪（MISE）是一台红外成分探测仪器，将搭载美国国家航空航天局（NASA）的“木卫二快船”任务前往木星系统。MISE旨在满足与该任务的成分科学目标相关的一级科学要求，即“通过成分和化学性质了解木卫二海洋的宜居性”，并为地质科学以及冰壳和海洋目标做出贡献，从而帮助“木卫二快船”实现其任务目标“探索木卫二以研究其宜居性”。MISE的质量为65千克，每次飞越所需能量为75.2瓦时。MISE将在0.8至5微米波段进行探测，光谱分辨率为10纳米，在100千米高度时每个像素的空间采样为25米，并有300个跨轨像素，能够区分木卫二上两种主要的水冰状态，识别感兴趣的主要非冰成分：盐、酸和有机物，以及检测痕量物质和一些热特征。此外，MISE将实现的空间分辨率和全球覆盖范围将由一些地面设备的更高光谱分辨率加以补充。MISE与“木卫二快船”其他有效载荷收集的观测数据相结合，将使我们在理解木卫二表面的大规模结构如何受地质过程塑造方面取得重大进展，并增进我们对微观尺度表面的理解。本文介绍了计划中的MISE科学调查、仪器设计、操作概念和数据产品。
