Book excerpt: In Space Enterprise - Living and Working Offworld, Dr Philip Harris provides the vision and rationale as to why humanity is leaving its cradle, Earth, to use space resources, as well as pursuing lunar industrialization and establishing offworld settlements. As a management/space psychologist, Dr. Harris presents a behavioral science perspective on space exploration and enterprise. In this his 45th book, Phil has completely revised and updated the two previous editions of this classic, placing new emphasis on the need for more synergy and participation by the private sector. He not only provides a critical review of what is happening in the global space community, but offers specific strategies for lunar economic development. The author analyzes the human factors in contemporary and future space developments, especially relative to the deployment of people aloft.
