Scott Kelly writes astronaut memoir about long-duration spaceflight, training and the physical and psychological demands of living aboard the International Space Station. Endurance follows his path from an unfocused student to Navy pilot and astronaut, then centres on his nearly year-long mission in orbit. Kelly describes launches, spacewalks, maintenance failures, exercise routines, isolation and the small practical details of eating, sleeping and working in microgravity. The book also discusses the strain placed on family relationships by repeated missions and extended absence. His prose is straightforward and operational, with risk and routine often sharing the same page. Endurance fits astronaut memoir, space exploration and aviation autobiography, particularly for readers interested in what daily life in orbit actually requires beyond headline moments. Read more Less
