There is an unbridged gap between human aspirations to travel into space and the barriers to realizing such dreams. Despite optimistic predictions, a viable space tourism industry has yet to emerge, with only a handful of 'millionaire' space tourists having experienced travel in outer space. Space tourism remains an elusive dream. This is the first comprehensive, multidisciplinary work on the emergent phenomenon of space tourism. Leading specialists from a range of fields cover a wide spectrum of topics including the space history and technology underpinning current developments; space tourists' motivations; and the environmental, social, and legal aspects concomitant with a space tourism industry. The book is unique in its focus on virtual forms of space travel, such as those manifesting in virtual reality, films, and games. The volume takes a nuanced and critical approach to the development of aspirations to leave Earth, stressing the far-reaching implications for the environment and for human life and society on Earth. The book is written in an approachable manner, making it accessible to both academics and the interested general reader. Owing to its interdisciplinary character, it should be of interest to practitioners and teachers across the sciences, humanities, and social sciences.
