摘要

探索木星轨道上的特洛伊小行星的“露西”任务携带了一台名为L 'Ralph的仪器，一台可见/近红外多光谱成像仪和一台短波红外高光谱成像仪。它是美国宇航局首次执行特洛伊任务的“露西”号的核心仪器之一。拉尔夫号的主要目的是绘制这些天体的表面地质和组成，但它也将用于寻找可能的脆弱的外逸层。它结构紧凑，质量低(32.3 kg)，功率高效(24.5 W)，具有高灵敏度和出色的成像能力。这些特点，以及它的高度冗余，使拉尔夫非常适合这种长时间的多次飞越侦察任务。

L’Ralph: A Visible/Infrared Spectral Imager for the Lucy Mission to the Trojans

Abstract The Lucy Mission to the Trojan asteroids in Jupiter’s orbit carries an instrument named L’Ralph, a visible/near infrared multi-spectral imager and a short wavelength infrared hyperspectral imager. It is one of the core instruments on Lucy, NASA’s first mission to the Trojans. L’Ralph’s primary purpose is to map the surface geology and composition of these objects, but it will also be used to search for possible tenuous exospheres. It is compact, low mass (32.3 kg), power efficient (24.5 W), and robust with high sensitivity and excellent imaging. These characteristics, and its high degree of redundancy, make L’Ralph ideally suited to this long-duration multi-flyby reconnaissance mission.

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.
