This 12-frame mosaic from the Galileo Solid-State Imaging Experiment (SSI) covers much of the anti-Jovian hemisphere of Io at 1.45 km/pixel, with Jupiter in the background. Unlike the other mosaics from the I24 flyby, these images were acquired in full-frame mode. Images acquired in that mode did not suffer from the scrambling inflicted on the summation mode images during I24. This mosaic was designed as part of a stereo pair along with a similar mosaic acquired during C21 in July 1999; however, the relative blandness of much of the terrain outside Io's mountains and volcanoes, plus the unusual phase functions of many of its surface materials complicate the development of digital elevation models from these two data sets. The scrambled raw data for this image was unscrambled by a program developed at JPL using the LabVIEW software from National Instruments of Austin, TX.
