We report on Ultraviolet Spectrometer observations of Ganymede from four orbits of the Galileo primary mission. During 12 observation sequences, regions on Ganymede's leading, trailing, and anti-Jovian hemispheres were observed at several latitudes a

The Galileo ultraviolet spectrometer has observed Jupiter's volcanically active moon Io in the 2100–3200 A wavelength range at 13.7 A resolution. We find that both sulfur dioxide frost on the surface and sulfur dioxide gas in Io's atmosphere are de

The Galileo ultraviolet spectrometer has measured the first-ever disk-resolved spectral ultraviolet albedos of regions on Europa's trailing and antijovian hemispheres at spatial resolutions approaching 55 km. We find that the ultraviolet albedo (2400

In 1996 and 1997 the Galileo Ultraviolet Spectrometer (UVS) obtained the first measurements of Jupiter's nightside midultraviolet (MUV) polar auroral spectrum from 1620 to 3231 A at 13 A resolution. The reduced polar spectra, after removal of off-axi

In 1996 during the first four orbits of the satellite tour the Galileo ultraviolet spectrometer (UVS) (11304320 A) and extreme ultraviolet spectrometer (EUVS) (540-1280 A) performed near-simultaneous observations of the Jupiter aurora in both the nor
