Featuring breathtaking photographs and documents from NASA's Jet Propulsion Laboratory, this illuminating book traces our history of Mars exploration. Starting with the earliest telescopic viewings, Mars moves through NASA's first flybys in the 1960s, to the landers in the 1970s, and the sophisticated rovers and orbiters now exploring every region of the planet. It also discusses in detail NASA's elaborate plans for crewed expeditions to Mars--along with compelling alternative missions.
