On the Cover: From this early portrait of Earth and its Moon together; to thousands of images of the outer planets, their rings and satellites; to the family gallery of Sun and planets that closed out its imaging mission, Voyager has done more than any other spacecraft to show us our place in the solar system.
Voyager 1 took this image on September 18, 1977, 13 days after it was launched. Nearly 13 years later, on February 14, 1990, it looked back toward Earth again, and returned a series of images of the planets that we feature in this issue. JPL / NASA
