Discover what the solar system looks like up close in this definitive collection of space exploration images. Since the 1960s, 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 discusses what the photos actually reveal about the places in simple language children will understand. The book includes a glossary, a bibliography, and an index. “Dramatic, unframed color photos on thick glossy paper…the science details are just as exciting as the pictures. Starting with a long chapter on the early history of astronomy, Benson examines the Solar System from the perspectives of robot explorers launched in the last 60 years. He also gives in-depth descriptions of how the photos were taken by unmanned spacecraft…The informal text raises the big questions that will captivate young readers: Are we alone in the universe? Has Mars ever supported life? Does life exist there now? Or elsewhere? More than 20 space probes are in action right now, and engaged readers will want to reference the listed Web sites. The comprehensive glossary is also a handy resource.”—Booklist
