Insightful, good-humored essays on the possibilities of alien life and the uses of space exploration, based on an astrobiologist’s everyday conversations with his fellow humans—taxi drivers, to be precise.If you’ve ever sat in the back seat of a taxi, you know that cabbies like to talk. Sports or politics, your job or theirs, taxi drivers are fine conversationalists on just about any topic. And when the passenger is astrobiologist Charles Cockell, that topic is usually space and what, if anything, lives out there.Inspired by conversations with drivers all over the world, Taxi from Another Planet tackles the questions that everyday people have about the cosmos and our place in it. Will we understand aliens? What if there isn’t life out in the universe? Is Mars our Plan B? And why is the government spending tax dollars on space programs anyway? Each essay in this genial collection takes questions like these as a starting point on the way to a range of insightful, even poignant, observations. Cockell delves into debates over the inevitability of life and looks to both human history and scientific knowledge to consider what first contact will be like and what we can expect from spacefaring societies. He also offers a forceful argument for the sympathies between space exploration and environmentalism.A shrewd and entertaining foray into the most fundamental mysteries, Taxi from Another Planet brings together the wisdom of scientific experts and their fellow citizens of Earth, the better to understand how life might unfold elsewhere.

A guide to understanding the formation of life in the Universe The revised and updated second edition of Astrobiology offers an introductory text that explores the structure of living things, the formation of the elements required for life in the Universe, the biological and geological history of the Earth, and the habitability of other planets. Written by a noted expert on the topic, the book examines many of the major conceptual foundations in astrobiology, which cover a diversity of traditional fields including chemistry, biology, geosciences, physics, and astronomy. The book explores many profound questions such as: How did life originate on Earth? How has life persisted on Earth for over three billion years? Is there life elsewhere in the Universe? What is the future of life on Earth? Astrobiology is centered on investigating the past and future of life on Earth by looking beyond Earth to get the answers. Astrobiology links the diverse scientific fields needed to understand life on our own planet and, potentially, life beyond. This new second edition: Expands on information about the nature of astrobiology and why it is useful Contains a new chapter “What is Life?” that explores the history of attempts to understand life Contains 20% more material on the astrobiology of Mars, icy moons, the structure of life, and the habitability of planets New ‘Discussion Boxes’ to stimulate debate and thought about key questions in astrobiology New review and reflection questions for each chapter to aid learning New boxes describing the careers of astrobiologists and how they got into the subject Offers revised and updated information throughout to reflect the latest advances in the field Written for students of life sciences, physics, astronomy and related disciplines, the updated edition of Astrobiology is an essential introductory text that includes recent advances to this dynamic field.

On the Moon or Mars, where even the oxygen you breathe is made in a manufacturing process controlled by someone else, can you be free? In Interplanetary Liberty: Building Free Societies in the Cosmos, Charles S. Cockell argues that beyond Earth, space is especially tyranny-prone. Yet rather than consign humanity to a dim future of extraterrestrial despotisms, he suggests that the construction of free societies is possible using uniquely blended and reformulated classical liberal ideas for the space frontier. Considering politics, science, engineering, art, education, prisons, and other facets of society, this book lays out the general ethos and culture around which settlements might be constructed to secure the establishment and flourishing of freedom in the cosmos.
