Foreword
In late summer of 1977, the United States launched two unmanned Voyager spacecraft onan extensive reconnaissance of the outer planets, a decade-long odyssey that could take themto 3 planets and as many as 18 planetary satellites. The first encounter was with the giantJovian planetary system, 645 million kilometers (400 million miles) away. Passing by Jupiterand its complex satellite system in 1979, the Voyager spacecraft have collected and returned toEarth an enormous amount of data and information that may prove to be a keystone in understandingour solar system.
This publication provides an early look at the Jovian planetary system and contains aselected sample from the more than 30,000 images collected during this phase of the Voyagermission. While Voyager achieved an impressive record of accomplishments, full realization ofthe scientific value of this program must await the remaining Voyager encounters with Saturnand perhaps Uranus, and a detailed analysis of the data from all the spacecraft investigations.
