The Visual and Infrared Mapping Spectrometer (VIMS) returned many both targeted and serendipitous observations of the Galilean Satellites during the Cassini mission flyby of Jupiter in December 2000. These observations consist of reflectance spectra between 0.35 and 5 †m with 12-nm spectral resolution of the integral disk of the satellites at a variety of phase angles and central longitudes. Selected observations have been calibrated and analyzed, including comparisons with earlier Galileo NIMS measurements. The objectives are to search for new spectral features, validate and expand on earlier discoveries, and improve the calibrations of VIMS. This is an ongoing effort and the latest results will be presented. At the time of the writing of this abstract, several results seem apparent. A major objectives was to search for the 13CO2 spectral feature next to the 12CO2 band near 4.26 †m observed by NIMS and analyzed earlier for Callisto and Ganymede [1,2]. A weak spectral feature appears in both the NIMS and VIMS spectra at the expected wavelength. If real, this implies an approximately chondritic ratio of 12C to 13C. The spectral absorption features at 4.05, 4.26, and 4.57 †m, interpreted as begin due to SO2, CO2 and CN, respectively, from the NIMS observations of Callisto and Ganymede [1] appear also in the VIMS data with the expected strengths, confirming the NIMS detections. Other findings are expected. [1] McCord, T.B. et al., Science, 278, 271, 1997; JGR, 103, 8603, 1998. [2] Hibbitts, C.A. et al., JGR, 105, 22,541, 2000.
