Outer space = infinite fascination! A delight for space fans and experts alike, this book is your unique guide to the legendary Voyager missions. After the worldwide success of Apollo VII-XVII, the authors again scoured the NASA archives to gather all the key facts and discoveries of this interstellar spacecraft, including previously unpublished information. First launched in 1977, the twin Voyager 1 and 2 space- craft have significantly expanded our knowledge of space, corrected many scientific theses and, last but not least, produced the most distant image of the earth: the famous "Pale Blue Dot."
