An outstanding science communicator, great storyteller, passionate space promoter, visionary, Carl Sagan believes that the desire to wander and expand the frontiers of knowledge is inherent in human nature and is related to our survival as a species. His heartfelt, compelling book interweaves philosophical musings with enthusiastic descriptions of triumphant explorations of the planets and moons, from both human lunar exploration and robotic missions. By introducing us to our space neighbors, Sagan not only enlightens and delights the reader, he also helps to understand how to protect the Earth.
