Blooms with such glorious rushes of exalted prose that I was dog- earing almost every page." --The New York Times Book Review As debate over the future of NASA heats up, award-winning author Stephen J. Pyne presents America's greatest space expeditions as the latest chapter in a continuous saga of discovery that goes back centuries. Pyne's luminous narrative not only recounts the Voyager 1 and Voyager 2 missions, launched in 1977 to explore the outer planets, but also fixes their place in Western civilization's urge to explore-an impulse that links NASA's scientists with Magellan, Columbus, Cook, Lewis and Clark, and other intrepid seekers through the ages. Pyne's eye-opening look at what he calls the third age of discovery "reminds readers of the rich cultural history that underlies humankind's exploration of the cosmos" (Science News).
