On the Cover: The blue planet Neptune and its tantalizing moon Triton are the last scheduled destinations on Voyager 2's Grand Tour of the outer solar system. Jupiter, Saturn and Uranus have all given up secrets to this robotic emissary from Earth, and the spacecraft will now probe the secrets of its last planet. After swinging past Triton and examining its atmosphere, Voyager 2 will begin a quest to find the edge of our solar system, and then will travel on forever through the realm of the stars.
