Description:

Neptune : The planet, rings and satellites tells the real story of the Voyager Mission to the outer planets. Written by two scientists directly involved with the mission, this book is the first to describe events from the point of view of the people who were really there. From this unique standpoint, the authors recreate the excitement generated as reams of spectacular data were fed back from Neptune, and interpret the results of all the Voyager investigations in non-scientific language. Four pages of spectacular colour photographs illustrate the wonders of this amazing planet.This book details the major advances in our knowledge of Neptune and its system, and will remain a definitive description of that planet for years to come.
