AI 中文摘要
欧空局主导的木卫冰卫星探测器（JUICE）任务搭载了一台由NASA提供、西南研究院建造的紫外光谱仪（JUICE-UVS）。JUICE-UVS旨在开展多种测量，以深化对木星冰卫星潜在宜居性的理解，并研究木星及其系统，将其作为气态巨行星的原型。JUICE-UVS在50-204纳米波长范围内观测光子，沿7.5度狭缝以中等光谱和空间分辨率工作，该狭缝由7.3度×0.1度和0.2度×0.2度的连续区域组成。JUICE-UVS将对冰卫星的大气、羽流、表面及局部空间环境，木星的大气与极光，木卫一及其等离子体环，以及木星系统的其他目标（环、小卫星等，视情况而定）开展综合研究。采用的观测技术包括：天底推扫成像、圆盘扫描、临边凝视、恒星与太阳掩星、木星凌日观测，以及中性云/等离子体环的凝视与扫描。本文结合JUICE任务的宜居性与木星系统目标，阐述了UVS研究的科学计划、仪器细节、操作概念及数据格式。
英文摘要
The Jupiter Icy Moons Explorer (JUICE) mission, led by ESA, has an Ultraviolet Spectrograph (JUICE-UVS) contributed by NASA and built at Southwest Research Institute. JUICE-UVS is designed to provide a diversity of measurements to further our understanding of the potential habitability of icy ocean worlds at Jupiter and to study Jupiter and the Jovian system as an archetype for gas giants. JUICE-UVS observes photons in the 50-204 nm wavelength range at moderate spectral and spatial resolution along a 7.5 deg slit composed of 7.3 deg x 0.1 deg and 0.2 deg x 0.2 deg contiguous sections. JUICE-UVS performs a comprehensive study of icy satellite atmospheres, plumes, surfaces, and local space environments; Jupiter's atmosphere and aurora; Io and its Io Plasma Torus; and other Jupiter system targets (rings, small moons, etc.) as available. The variety of observational techniques employed include: nadir push-broom imaging, disk scans, limb stares, stellar and solar occultations, Jupiter transit observations, and neutral cloud/plasma torus stares and scans. This paper describes the UVS investigation's science plans, instrument details, concept of operations, and data formats in the context of the JUICE mission's habitability and Jupiter system goals.
