The Lunar Reconnaissance Orbiter Lyman-Alpha Mapping Project (LAMP) has been mapping the Moon since its launch in 2009. Faint ultraviolet illumination of the lunar dark side includes light from stars and from hydrogen Ly α emissions, mostly attribut

We obtained New Horizons LORRI images to measure the cosmic optical background (COB) intensity integrated over 0.4 μ m ≲ λ ≲ 0.9 μ m. The survey comprises 16 high-Galactic-latitude fields selected to minimize scattered diffuse Galactic light (

Ultraviolet spectroscopy is a powerful method to study planetary surface composition through reflectance measurements, atmospheric composition through stellar/solar occultations, transits of other planetary bodies, and direct imaging of airglow and a

The Cassini Orbiter Ultraviolet Imaging Spectrograph (UVIS) obtained interplanetary hydrogen Ly α observations from 1999 to 2017, with mid-2004 to 2017 observations obtained from Saturn orbit. During its Saturn orbital phase, the spacecraft moved fr

Abstract Europa Clipper will arrive at Jupiter at the end of this decade and will explore Europa through a series of flybys. One of its many goals is to characterize Europa's topography and global shape using the Europa Imaging System and Radar for E

Juno flew within 1053 km of the surface of Ganymede on June 7, 2021. A unique data set of the interaction of its magnetosphere with the magnetosphere of Jupiter was obtained during the flyby. Auroral imaging was carried out by the UVS experiment simu

We combine novel laboratory experiments and exospheric modeling to reveal that “dynamic” Ly-α photolysis of Plutonian methane generates a photolytic refractory distribution on Charon that increases with latitude, consistent with poleward darkeni
