RaveNPR...a powerful report ... The book makes for fascinating reading. The history, dating back to Ancient Greece and before, and stretching to current events, is meticulously researched. There are copious notes and bibliographical references. The science is carefully explained, with Tyson\'s trademark passionate clarity ... Tyson retells the history of space exploration, and of the Cold War, excelling in bringing forth the entangled advances of science and military interests ...
