Book Description: Astrobiology is the study of the origin, evolution, distribution, and future of life in the universe. It is an inherently interdisciplinary field that encompasses astronomy, biology, geology, heliophysics, and planetary science, including complementary laboratory activities and field studies conducted in a wide range of terrestrial environments. Combining inherent scientific interest and public appeal, the search for life in the solar system and beyond provides a scientific rationale for many current and future activities carried out by the National Aeronautics and Science Administration (NASA) and other national and international agencies and organizations. Requested by NASA, this study offers a science strategy for astrobiology that outlines key scientific questions, identifies the most promising research in the field, and indicates the extent to which the mission priorities in existing decadal surveys address the search for life's origin, evolution, distribution, and future in the universe. This report makes recommendations for advancing the research, obtaining the measurements, and realizing NASA's goal to search for signs of life in the universe.

Book Description: Extraterrestrial life is a common theme in science fiction, but is it a serious prospect in the real world? Astrobiology is the emerging field of science that seeks to answer this question. The possibility of life elsewhere in the cosmos is one of the most profound subjects that human beings can ponder. Astrophysicist Andrew May gives an expert overview of our current state of knowledge, looking at how life started on Earth, the tell-tale ‘signatures’ it produces, and how such signatures might be detected elsewhere in the Solar System or on the many ‘exoplanets’ now being discovered by the Kepler and TESS missions. Along the way the book addresses key questions such as the riddle of Fermi’s paradox (‘Where is everybody?’) and the crucial role of DNA and water – they’re essential to ‘life as we know it’, but is the same true of alien life? And the really big question: when we eventually find extraterrestrials, will they be friendly or hostile?

Book Description: Are we alone in the universe? As humans, are we unique or are we part of a greater cosmic existence? What is lifeÕs future on Earth and beyond? How does life begin and develop? These are age-old questions that have inspired wonder and controversy ever since the first people looked up into the sky. With todayÕs technology, however, we are closer than ever to finding the answers. Astrobiology is the relatively new, but fast growing scientific discipline that involves trying to understand the origin, evolution, and distribution of life within the universe. It is also one of the few scientific disciplines that attracts the publicÕs intense curiosity and attention. This interest stems largely from the deep personal meaning that the possible existence of extraterrestrial life has for so many. Whether this meaning relates to addressing the ÒBig QuestionsÓ of our existence, the possibility of encountering life on other planets, or the potential impact on our understanding of religion, there is no doubt that the public is firmly vested in finding answers. In this broadly accessible introduction to the field, Bruce Jakosky looks at the search for life in the universe not only from a scientific perspective, but also from a distinctly social one. In lucid and engaging prose, he addresses topics including the contradiction between the publicÕs fascination and the meager dialogue that exists between those within the scientific community and those outside of it, and what has become some of the most impassioned political wrangling ever seen in government science funding.

Book Description: In these lively and fascinating essays, scientists from around the world weigh in on the latest advances in the search for intelligent life in the universe and discuss just what that might look like. Since 2000, science has seen a surge in data and interest on several fronts related to E.T. (extraterrestrials); A.I. (artificial intelligence); and SETI (search for extraterrestrial intelligence). The debate has intensified over whether life exists outside our solar system, what that life would look like, and whether we’ll ever make contact. Included here are essays from a broad spectrum of the scientific community: cosmologists, astrophysicists, NASA planetary scientists, and geneticists, to name just a few, discussing the latest research and theories relating to alien life. Some of the topics include: If life exists somewhere in space, what are the odds that it evolves into something we would recognize as intelligent? What will space travel look like in the future, and will it all be done by cyborg technology? How long until we are ruled by robot overlords? (This is actually a serious consideration.) Are we simply a simulation in the mind of some supreme being, acting out a virtual reality game? For those who have ever wondered, Is there anybody out there? here are the latest theories and evidence that move us closer to answering that question.

Book Description: Mars has captured the human imagination for decades. Since NASA’s establishment in 1958, the space agency has looked to Mars as a compelling prize, the one place, beyond the Moon, where robotic and human exploration could converge. Remarkably successful with its roaming multi-billion-dollar robot, Curiosity, NASA’s Mars program represents one of the agency’s greatest achievements. Why Mars analyzes the history of the robotic Mars exploration program from its origins to today. W. Henry Lambright examines the politics and policies behind NASA's multi-decade quest, illuminating the roles of key individuals and institutions along with their triumphs and defeats. Lambright outlines the ebbs and flows of policy evolution, focusing on critical points of change and factors that spurred strategic reorientation. He explains Mars exploration as a striking example of "big science" and describes the ways a powerful advocacy coalitionâ€�composed of NASA decision makers, the Jet Propulsion Laboratory, the Mars academic science community, and many othersâ€�has influenced governmental decisions on Mars exploration, making it, at times, a national priority. The quest for Mars stretches over many years and involves billions of dollars. What does it take to mount and give coherence to a multi-mission, big science program? How do advocates and decision makers maintain goals and adapt their programs in the face of opposition and budgetary stringency? Where do they succeed in their strategies? Where do they fall short? Lambright’s insightful book suggests that from Mars exploration we can learn lessons that apply to other large-scale national endeavors in science and technology.
