In an era of public Mars fascination, this book offers an objective presentation of the challenges of crewed Mars missions and discusses scenarios of Mars settlements under scientific, technical, social, economic, ethical and political aspects. With the aim to make the reader comprehend what is plausible and what is at stake, the book tries to clarify misconceptions and half-truths spreading rapidly in the public. The authors argue that approximations and misinformation should be countered for two main reasons. First, to avoid missing out on the benefits that Mars exploration may bring, including major scientific discoveries and an inspiring, federative human endeavor. Second, to remediate dangerous delusions – such as the idea that humanity could be transferred there should the Earth become inhabitable in the near term. In preparation for this book a group of European, world-renowned scientists from fields as diverse as astronomy, planetology, geology, biology, philosophy, or economics, as well as astronauts and science-fiction writers, was gathered to discuss Mars missions ranging from near-term robotic missions, all the way to large-scale settlements and even the feasibility of terraforming. For each, they draw arguments from their domains of expertise to discuss what is feasible and what is desirable. The result provides researchers with an objective review of the field, policy makers with a reference to make informed decisions, and the general public with a tool to form educated opinions.

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

Approaching the settlement of our Moon from a practical perspective, this book is well suited for space program planners. It addresses a variety of human factor topics involved in colonizing Earth's Moon, including: history, philosophy, science, engineering, agriculture, medicine, politics & policy, sociology, and anthropology. Each chapter identifies the complex, interdisciplinary issues of the human factor that arise in the early phases of settlement on the Moon. Besides practical issues, there is some emphasis placed on preserving, protecting, and experiencing the lunar environment across a broad range of occupations, from scientists to soldiers and engineers to construction workers. The book identifies utilitarian and visionary factors that shape human lives on the Moon. It offers recommendations for program planners in the government and commercial sectors and serves as a helpful resource for academic researchers. Together, the coauthors ask and attempt to answer: “How will lunar society be different?”
