New Frontiers in Astrobiology presents a simple and concise overview of the emerging field of astrobiology. Astrobiology studies the evolution, origin, and future of life on Earth and beyond. This book provides a brief overview of the current research and future status of this fascinating field. The book covers a wide range of topics from the history of astrobiology, the big bang, prebiotic chemistry, theories of the origin of life, extreme environments on Earth, and the quest for intelligent life in space. Currently, there is a critical gap in knowledge related to the future scope of astrobiology and its applications in science and society. The hallmark of the book is that it takes critical perspectives to analyze the new frontiers in astrobiology post Mars 2020/ExoMars missions that encompass the latestdevelopments in the detection of biosignatures and habitability beyond our Solar System (exomoons, exoplanets). The book will be a valuable resource for students, researchers, and scientists who seek greater insights into understanding the current status and future of astrobiology. - Explores the background and historical developments in astrobiology - Provides concise cutting-edge reviews on fundamental questions on origin and distribution of life on Earth, habitability beyond Earth, and future of life on Earth - Integrates contemporary and critical views in new frontiers in astrobiology

Space Science and Public Engagement: 21st Century Perspectives and Opportunities critically examines the many dimensions of public engagement with space science by exploring case studies that show a spectrum of public engagement formats, ranging from the space science community's efforts to communicate developments to the public, to citizenry attempting to engage with space science issues. It addresses why public engagement is important to space science experts, what approaches they take, how public engagement varies locally, nationally and internationally, and what roles'non-experts'have played in shaping space science. Space scientists, outreach specialists in various scientific disciplines, policymakers and citizens interested in space science will find great insights in this book that will help inform their future engagement strategies. - Critically examines how expert organizations and the space science community have sought to bring space science to the public - Examines how the public has responded, and in some cases self-organized, to opportunities to contribute to space science - Outlines future engagement interests and possibilities
