Description
Ambassadors from Earth relates the story of the first unmanned space probes and planetary explorers—from the Sputnik and Explorer satellites launched in the late 1950s to the thrilling interstellar Voyager missions of the '70s—that yielded some of the most celebrated successes and spectacular failures of the space age. Keep in mind that our first mad scrambles to reach orbit, the moon, and the planets were littered with enough histrionics and cliffhanging turmoil to rival the most far-out sci-fi film. Utilizing original interviews with key players, bolstered by never-before-seen photographs, journal excerpts, and primary source documents, Jay Gallentine delivers a quirky and unforgettable look at the lives and legacy of the Americans and Soviets who conceived, built, and guided those unmanned missions to the planets and beyond. Of special note is his in-depth interview with James Van Allen, the discoverer of the rings of planetary radiation that now bear his name.
