A stunning memoir from the astronaut who spent a record-breaking year aboard the International Space Station, a candid account of his remarkable voyage, of the journeys off the planet that preceded it, and of his colorful formative years. The veteran of four space flights and the American record holder for consecutive days spent in space, Scott Kelly has experienced things very few have. He describes navigating the extreme challenge of long-term spaceflight, both existential and banal: the devastating effects on the body; the isolation from everyone he loves and the comforts of Earth; the pressures of constant close cohabitation; the catastrophic risks of depressurization or colliding with space junk, and the still more haunting threat of being unable to help should tragedy strike at home; an agonizing situation Kelly faced when, on another mission, his twin brother's wife, Gabrielle Giffords, was shot while he still had two months in space.
