Voyager to Jupiter

Overview

When Voyager 1 flew past Jupiter in March of this year, it sent back results which surprised even the space-planners. The famous Red Spot was shown as a huge whirling storm, while one of the satellites, Io, a world larger than our Moon, has a brilliant red surface upon which active volcanoes can be seen. Patrick Moore and Dr Garry Hunt discuss Voyager l's remarkably successful mission.
