Only 628 people in human history have left Earth. Tim Peake traces the lives of some of these remarkable men and women, from Yuri Gagarin to Neil Armstrong, Valentina Tereshkova to Peggy Whitson. He describes the wondrous view of Earth, the surreal weightlessness, the extraordinary danger, the surprising humdrum, the unexpected humour, the psychological pressures, the physical toll, the thrill of launch and trepidation of re-entry. He also examines the surprising, shocking and often poignant stories of astronauts back on Earth, whose lives are forever changed as they readjust to terra firma. A former Apache helicopter pilot, flight instructor and test pilot, Peake was the first British astronaut to visit the International Space Station. In conversation with Andy Fryers, Sustainability Director, Hay Festival Global.
