The emerging commercial space industry is raising new types of ethical questions about the privatization of space travel and planetary exploration. The industry is carrying out commercial endeavors ahead of the development of specifically established government regulations and industry standards. Much of the oversight of commercial space flight emerges from the Federal Aviation Administration and commercial space industries. As lucidly explained in this book, the ethical issues of space flight involve human safety issues, environmental quality concerns, and business conduct and integrity practices typically associated with new technologies and entrepreneurial ventures. The author compares the ramifications of current planetary space flight endeavors to those of the long-distance ocean voyages early peoples seeking resources and livelihoods in distant lands made. The text also describes novel ethical concerns related to living in space and encountering life-forms that may exist on other planets. The viewpoints expressed in the book are pragmatic and based on the author's experiences as director of a technology ethics program. Green discusses the philosophical principles underlying each ethical concern of interest. A case study, discussion questions, and recommended further readings from primary sources supplement each chapter. Recommended. All readers.
