This book offers a look at some of the most fascinating early American space robot programs like the Pioneer, Viking, and Voyager. With a focus on early robot spacecraft that came out of the Space Age, readers will be taken through the period of exploration from the past six decades, during which time the United States became the first country to reach every major planet from Mercury to Neptune. This eBook provides a historic snapshot of how space robots emerged from simple, often unreliable exploring devices into sophisticated scientific platforms that now extend human consciousness and intelligent inquiry to the edges of the solar system and beyond.
