Living in Space is a captivating study across a wide spectrum of the issues that humanity faces, as we look beyond our home planet at future needs, future business endeavors, future learning opportunities, and future homes for our children and theirs. The authors who contributed to this volume present us with a wonderful diversity of perspectives, including the arts, philosophy, business, science, and technology, and the story that emerges from their fine writings engages the imagination. These chapters also engage our vision, and I hope this book helps us to muster the will and the commitment to proceed with the development of space for the benefit of all humanity, as it should be. I hope you enjoy this book as much as I did. — Edgar Mitchell, Sc.D., Apollo 14 Astronaut, March 26, 2009
