Abstract

The Cassini Imaging Science Subsystem acquired about 26,000 images of the 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.

3. From 11 to 13 December 2000 the ISS acquired a 1 × 2 mosaic every hour for 38 hours producing 29 pairs of images each separated from the other by one planetary rotation (10 hours). Wind measurements were taken from these image pairs. Spatial resolution ranged from 122 to 114 km/pixel resulting in a wind speed precision of ∼3.3 m/s. Images were navigated on the planetary limb calibrated radiometrically assembled into spatial mosaics and mapped with a simple cylindrical projection. Illumination effects were removed by dividing the brightness values by the cosine of the solar incidence angle. Zonal winds were measured with an automatic line-shifting method. Each map line spans 0.1° latitude (∼1250 km). Because blocks of five lines were shifted and digitally correlated the latitudinal resolution of our zonal velocity profile is 0.5°.
