"The big question-whether there was or is life on the Red Planet . . . gets a close, smart and readable examination."---Jeffrey Kluger, TIME "The 'life' on Mars [Weintraub] envisions in these terrific pages isn't romantic civilizations of green warriors: It's humans, moving first to set foot on the red planet and then to explore it and then to colonize it. Weintraub tackles every aspect of how humans could set up shop, all of it based on the successive space probes that have been launched over the decades. Weintraub tells the stories of this amazing exploration-tale with the authority of an astronomy professor and the verve of a true believer."---Steve Donoghue, Christian Science Monitor "Explore not only our potential futures (and a reality check on Mars hype) but also how our fascination with our neighboring planet got us to where we are today."---Mary Beth Griggs, Popular Science "Surveying 'the many attempts to identify life on Mars' since the 17th century, the book urges caution about 'chasing Martians' in light of the risk that we might inadvertently destroy any life there 'before we have a chance to fully explore the red planet.'" * Times Higher Education * "[Life on Mars] is a comprehensive review of Mars. . . . Well worth the read."---Niamh Shaw, BBC Sky at Night
