This book introduces the history of the discovery and observation of Jupiter, Saturn, Uranus and Neptune to provide a measure of context into which the Voyager mission can be placed. It will discuss the development of procedures for sending spacecraft deep into the Solar System and relate the discoveries made at each of the giant planets in turn, before bringing the story into the present century as both Voyagers pushed outside the Sun’s realm for the first time. However, in view of the tremendous quantity of new data from Galileo at Jupiter, Cassini at Saturn, the Earth-orbiting Hubble Space Telescope and observatories on the ground, an attempt will be made to bring the story up to date. In a small way, NASA’s Voyager Missions seeks to commemorate what may be one of few space science missions which could still be clearly remembered a thousand years from now: the missions which enabled us to explore our celestial neighbourhood for the first time and set sail for the stars.
