The Cassini Ultraviolet Imaging Spectrograph Investigation
Larry W. Esposito,Charles A. Barth,Joshua Colwell,George M. Lawrence,William E. McClintock,A. Ian F. Stewart,H. Uwe Keller,A. Korth,Hans Lauche,Michel C. Festou,Arthur L. Lane,Candice Hansen,Justin N. Maki,Robert A. West,Herbert Jahn,Ralf Reulke,Kerstin Warlich,Donald E. Shemansky,Yuk L. Yung +18 more
TL;DR: The Cassini Ultraviolet Imaging Spectrograph (UVIS) as discussed by the authors is part of the remote sensing payload of the Cassini orbiter spacecraft and has two spectrographic channels that provide images and spectra covering the ranges from 56 to 118 nm and 110 to 190 nm.
Journal ArticleDOI
Rapid and extensive surface changes near Titan's equator: evidence of April showers.
Elizabeth P. Turtle,Jason Perry,Alexander G. Hayes,Ralph D. Lorenz,Jason W. Barnes,Alfred S. McEwen,Robert A. West,A. D. Del Genio,J. Barbara,Jonathan I. Lunine,E. L. Schaller,T. L. Ray,Rosaly M. C. Lopes,Ellen R. Stofan +13 more
TL;DR: The detection by Cassini's Imaging Science Subsystem of a large low-latitude cloud system early in Titan’s northern spring and extensive surface changes in the wake of this storm are reported, which suggests that the dry channels observed at Titan's low latitudes are carved by seasonal precipitation.
Journal ArticleDOI
Jupiter's Cloud Structure from Galileo Imaging Data☆
Don Banfield,Peter J. Gierasch,M. Bell,Eugene A. Ustinov,Andrew P. Ingersoll,Ashwin R. Vasavada,Robert A. West,M. J. S. Belton +7 more
TL;DR: The vertical structure of aerosols on Jupiter was inferred from data obtained by the NASA Galileo Solid State Imaging system during the first six orbits of the spacecraft as discussed by the authors, which is consistent with previous conclusions based on data of lower spatial resolution.
Journal ArticleDOI
The Cassini UVIS stellar probe of the Titan atmosphere.
Donald E. Shemansky,A. Ian F. Stewart,Robert A. West,Larry W. Esposito,J. T. Hallett,Xianming Liu +5 more
TL;DR: The Cassini Ultraviolet Imaging Spectrometer (UVIS) observed the extinction of photons from two stars by the atmosphere of Titan during the Titan flyby to determine the asymptotic kinetic temperature at the top of the atmosphere.
Journal ArticleDOI
Ultraviolet Imaging Spectroscopy Shows an Active Saturnian System
Larry W. Esposito,Joshua Colwell,Kristopher Larsen,Willian E. McClintock,A. Ian F. Stewart,J. T. Hallett,Donald E. Shemansky,Joseph M. Ajello,Candice Hansen,Amanada R. Hendrix,Robert A. West,H. Uwe Keller,A. Korth,Wayne Pryor,Ralf Reulke,Yuk L. Yung +15 more
TL;DR: Neutral oxygen in the saturnian system shows variability, and the total number of oxygen atoms peaks at 4 × 1034, which is consistent with initially pure water ice bombarded by meteors.
