Observations with the Visual and Infrared Mapping Spectrometer (VIMS) during Cassini's flyby of Jupiter

Constraining the surface properties of Saturn's icy moons, using Cassini/CIRS emissivity spectra

“…Hendrix et al (2005) used a similar model to analyze UV solar phase curves from Galilean satellites obtained from combined Galileo UVS, HST, and IUE observations, obtaining also global porosities of ∼95% for Europa. Near-infrared solar phase curves with very good angular resolution near opposition were obtained for Europa by VIMS during the Cassini Jupiter flyby, yielding porosities of ∼99%, using a similar model and assumptions as previous authors (Brown et al, 2003).…”

Observations in the Saturn system during approach and orbital insertion, with Cassini's visual and infrared mapping spectrometer (VIMS)

“…Previous reports on VIMS observations of Venus (Baines et al 2000) and Jupiter and its satellites (Brown et al 2003;Bellucci et al 2004;Chamberlain & Brown 2004;McCord et al 2004;Simonelli & Buratti 2004) made en route to the Saturn system have already appeared. VIMS is an imaging spectrometer capable of obtaining data at 352 separate wavelengths simultaneously, with an angular resolution of 0.17 × 0.17 mrad over the wavelength region 0.35-1.08 µm (the Vis, or visual channel), and an angular resolution of 0.25 × 0.5 mrad over the range 0.85-5.2 µm (the IR, or infrared channel).…”

Carbon dioxide segregation in 1:4 and 1:9 CO2:H2O ices

“…In the Jupiter system, the Galilean satellites Europa, Ganymede and Callisto (Brown et al, 2003;McCord et al, 1997McCord et al, , 1998 also show CO 2 features in their spectra. In all these cases, * Corresponding author.…”
