What would it be like to visit Mars—to explore the distinctive, untouched terrain that inspired astronomers and stirred so many sci-fi writers? imaginations? Two highly capable robotic geologists—Spirit and Opportunity—made that amazing voyage, and spent the last four years roaming the Red Planet?s unique landscape. Thanks to 120 stunning 3-D and color images shot by these rovers, we can come along—and right now, it?s the closest we can get to actually setting foot on Mars. These super-realistic pictures pop off the page, allowing us to see for ourselves the rocks, craters, valleys, and other geologic configurations that define the Martian terrain. Compelling and accessible text guides us on this exhilarating tour, revealing the thrill of each discovery, along with the perils and near misses. Featuring a fold-out flap with embedded 3-D viewer (which actually allows customers to view the three-dimensional images right in the store), it?s the perfect gift for any armchair astronomer.
