Virts spent more than 200 days in space and took more photographs of Earth from above than anyone else.
With a foreword by Buzz Aldrin and 300 photographs, the book marries Virts' photographs with glimpses of everyday life in orbit.
Hundreds of Virts' photographs accompany his stories, and each chapter includes a Viewfinder, a gallery of Virts' photographs of space-station life and the spectacular panorama of Earth and the cosmos that come with it.
