  1. UVIS Input to Cassini Quarterly Report L.W. Esposito January 24, 2007 (For November 2006 - January 2007)

  2. UVIS Accomplishments • Science Highlights • Detailed modeling of spectra of Iapetus, Phoebe, Hyperion and Enceladus • Rhea data analyzed to look for bound oxygen atmosphere (no detectable atmosphere). Upper limits calculated for oxygen atmosphere column density based on non-detection • Investigated whether UVIS can detect dense jets in Enceladus’ plume • Analysis of wakes and waves in Saturn’s rings shows self-gravity and overstability

  3.
