The Voyager Missions
Sep 7, 1977
The two Voyager probes to the outer planets are probably the most ambitious of all automatic space-craft launched up to the present time. They should send back important new information about Jupiter, Saturn and their satellites - they may even go on to study Uranus and Neptune before finally leaving the Solar System altogether. Patrick Moore discusses the Voyager projects with Dr Garry Hunt of University College London, who has been involved in the planning of the missions.
