Cassini Imaging of Jupiter’s Atmosphere, Satellites, and Rings

Jupiter system as the spacecraft encountered the giant planet en route to Saturn. We report findings on Jupiter’s zonal winds, convective storms, low-latitude upper troposphere, polar stratosphere, and northern aurora. We also describe previously unseen emissions arising from Io and Europa in eclipse, a giant volcanic plume over Io’s north pole, disk-resolved images of the satellite Himalia, circumstantial evidence for a causal relation between the satellites Metis and Adrastea and the main jovian ring, and information on the nature of the ring particles. The Cassini spacecraft was launched in October 1997 and, en route to Saturn, en-countered Jupiter in December 2000. Dur-ing this event, the Cassini Imaging Science Subsystem (ISS), the highest resolution two-dimensional imager on the Cassini or-biter (1), collected 26,000 images of Ju
