How Voyager 2 has been reprogrammed

The Pioneer 11 and the Voyager 1 encounters with Saturn have revealed a remarkable richness and diversity of physical phenomena. As a result of these discoveries and of continued earth-based studies, major changes have been made in the observations planned for Voyager 2. A description is presented of some of the opportunities for new observations to be made by Voyager 2, taking into account four major areas of investigation, including the atmosphere, rings, satellites, and magnetosphere. The study of the dynamics of Saturn's atmosphere is of interest because Saturn, like Jupiter, is a giant rapidly-rotating body composed mainly of hydrogen and helium, encircled by bands of clouds of frozen ammonia. More information is to be obtained concerning the B-ring and the F-ring, and images with better resolution of Hyperion and Iapetus are to be returned.
