Discover what the solar system looks like up close in this definitive collection of space exploration. Since the 1960s, the NASA has been sending unmanned satellites to explore the planets, moons, and sun. These probes have amassed a stunning visual record of other worlds, revealing not one but scores of new frontiers, from rust-red Mars to Saturn with its ethereal rings. Michael Benson has pulled together the most spectacular of these images into a volume that focuses on the awesome appearance of these celestial bodies. He discusseswhat the photos actually reveal about the places in simple language children will understand. The book includes a glossary, a bibliography, and an index.
