The National Aeronautics and Space Administration's Jet Propulsion Laboratory has been making images and data obtained by the Galileo Solid State Imaging (SSI) system available on an ongoing basis for some time (see, for instance, the
Scout Report for September 12, 1997). However, for the first time, complete image data from the first nine orbits (G1-G9) have been merged, validated, and made available via the Planetary Data System (discussed in the
Scout Report for June 3, 1994). Users can search this impressive collection by a number of parameters, including target name, spacecraft clock, latitude/longitude, filter, phase angle, exposure, gain, and compression ratio. The JPL notes that to support the various needs of the scientific community, "the archived files are raw data files which merge the multiple downlinks of data to provide the best final version of an image. Supporting data such as calibration files are also available. Such files include dark currents, radiometric calibrations, blemishes, hot pixels, etc." Additional resources at the site include complete SSI data sets from the Galileo Cruise Phase (Earth launch to Jupiter arrival, 10/89-12/95).
