UVIS Accomplishments
• Science Highlights
–
–
–
Received Ed Stone award for the 2006 Outstanding Research Publication, for our Enceladus
paper:
• “Enceladus’ Water Vapor Plume”, published in Science
Detailed modelling 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
• Analysis was written up and supplied to Geraint Jones for inclusion in his Rhea paper
(we are co-authors)
• Rhea paper was submitted to Nature
