John Larsen is an Alberta writer, a former navy diver and military public affairs officer, who spent three years in conversation with astronaut Jeremy Hansen to write this book. Earthrise follows Hansen from a childhood in a farming community near London, Ontario, where he dreamed of the Moon, through his years of training with the Canadian Space Agency, to his seat on NASA's Artemis II, the first crewed Artemis flight around the Moon. Much of it is told from Hansen's side of the experience: the long preparation, the crew of four, and the family waiting on the ground. Larsen presents the mission as a story about teamwork and about people staying human under pressure, and he wrote it for general readers rather than space specialists. The title points back to the Earthrise photograph taken on Apollo 8, and the book opens with a foreword by Chris Hadfield.
The book is not a technical history of the rocket. It stays close to one person: what it took for Hansen to get a seat, what he carried with him, and who was waiting at home. Larsen has said it is not only for space fans, and the human parts carry it.
Read for yourself, the lesson is about any long goal. The visible moment is short. Most of the work happens in the years before it, among the people who make it possible, and in the conversations you have before you go.
