Abstract
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.
