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.

Three recent developments have greatly increased interest in the search for life on Mars. The first is new information about the Martian environment including evidence of a watery past and the possibility of atmospheric methane. The second is the possibility of microbial viability on Mars. Finally, the Vision for Space Exploration initiative included an explicit directive to search for the evidence of life on Mars. These scientific and political developments led NASA to request the NRC's assistance in formulating an up-to-date integrated astrobiology strategy for Mars exploration. Among other topics, this report presents a review of current knowledge about possible life on Mars; an astrobiological assessment of current Mars missions; a review of Mars-mission planetary protection; and findings and recommendations. The report notes that the greatest increase in understanding of Mars will come from the collection and return to Earth of a well-chosen suite of Martian surface materials.

The search for life in the solar system and beyond has to date been governed by a model based on what we know about life on Earth (terran life). Most of NASA's mission planning is focused on locations where liquid water is possible and emphasizes searches for structures that resemble cells in terran organisms. It is possible, however, that life exists that is based on chemical reactions that do not involve carbon compounds, that occurs in solvents other than water, or that involves oxidation-reduction reactions without oxygen gas. To assist NASA incorporate this possibility in its efforts to search for life, the NRC was asked to carry out a study to evaluate whether nonstandard biochemistry might support life in solar system and conceivable extrasolar environments, and to define areas to guide research in this area. This book presents an exploration of a limited set of hypothetical chemistries of life, a review of current knowledge concerning key questions or hypotheses about nonterran life, and suggestions for future research.

Astrobiology is an expanding, interdisciplinary field investigating the origin, evolution and future of life in the universe. Tackling many of the foundational debates of the subject, from discussions of cosmological evolution to detailed reviews of common concepts such as the 'Rare Earth' hypothesis, this volume is the first systematic survey of the philosophical aspects and conundrums in the study of cosmic life. The author's exploration of the increasing number of cross-over problems highlights the relationship between astrobiology and cosmology and presents some of the challenges of multidisciplinary study. Modern physical theories dealing with the multiverse add a further dimension to the debate. With a selection of beautifully presented illustrations and a strong emphasis on constructing a unified methodology across disciplines, this book will appeal to graduate students and specialists who seek to rectify the fragmented nature of current astrobiological endeavour, as well as curious astrophysicists, biologists and SETI enthusiasts.

This book aims at providing a brief but broad overview of biosignatures. The topics addressed range from prebiotic signatures in extraterrestrial materials to the signatures characterising extant life as well as fossilised life, biosignatures related to space, and space flight instrumentation to detect biosignatures either in situ or from orbit. The book ends with philosophical reflections on the implications of life elsewhere. In the 15 chapters written by an interdisciplinary team of experts, it provides both detailed explanations on the nature of biosignatures as well as useful case studies showing how they are used and identified in ancient rocks, for example. One case study addresses the controversial finding of traces of fossil life in a meteorite from Mars. The book will be of interest not only to astrobiologists but also to terrestrial paleontologists as well as any reader interested in the prospects of finding a second example of life on anotherplanet.

The United States possesses a treasure-trove of extraterrestrial samples that were returned to Earth via space missions over the past four decades. Analyses of these previously returned samples have led to major breakthroughs in the understanding of the age, composition, and origin of the solar system. Having the instrumentation, facilities and qualified personnel to undertake analyses of returned samples, especially from missions that take up to a decade or longer from launch to return, is thus of paramount importance if the National Aeronautics and Space Administration (NASA) is to capitalize fully on the investment made in these missions, and to achieve the full scientific impact afforded by these extraordinary samples. Planetary science may be entering a new golden era of extraterrestrial sample return; now is the time to assess how prepared the scientific community is to take advantage of these opportunities. Strategic Investments in Instrumentation and Facilities for Extraterrestrial Sample Curation and Analysis assesses the current capabilities within the planetary science community for sample return analyses and curation, and what capabilities are currently missing that will be needed for future sample return missions. This report evaluates whether current laboratory support infrastructure and NASA's investment strategy is adequate to meet these analytical challenges and advises how the community can keep abreast of evolving and new techniques in order to stay at the forefront of extraterrestrial sample analysis.

This book aims to contribute significantly to the understanding of issues of value (including the ultimate value of space-related activities) which repeatedly emerge in interdisciplinary discussions on space and society. Although a recurring feature of discussions about space in the humanities, the treatment of value questions has tended to be patchy, of uneven quality and even, on occasion, idiosyncratic rather than drawing upon a close familiarity with state-of-the-art ethical theory. One of the volume's aims is to promote a more robust and theoretically informed approach to the ethical dimension of discussions on space and society. While the contributions are written in a manner which is accessible across disciplines, the book still withstands scrutiny by those whose work is primarily on ethics. At the same time it allows academics across a range of disciplines an insight into current approaches toward how the work of ethics gets done. The issues of value raised could be used to inform debates about regulation, space law and protocols for microbial discovery as well as longer-range policy debates about funding.

PEN Literary Award Winner: “The best, most entertaining examination of the possibility of other life in the universe since [Carl] Sagan’s best work.” —Boulder Daily Camera It’s been decades since Carl Sagan first addressed the general public about the possibility of extraterrestrial life from a scientist’s perspective. We’ve learned a lot in those years, and now planetary scientist David Grinspoon investigates the big questions: How widespread are life and intelligence in the cosmos? Is life on Earth an accident, or in some sense the “purpose” of this universe? And how can we, working from the Earth-centric definition of “life,” even begin to think about the varieties of life-forms on other planets? In accessible, lively prose, and using the topic of extraterrestrial life as a mirror with which to view human beliefs, evolution, history, and aspirations, Grinspoon takes us on a three-part journey—the history of our expanding awareness of other planets and our ideas on alien life dating back to the earliest days of astronomy; the science of cosmic evolution and the evolution of life on Earth, including a critique of the “Rare Earth hypothesis”; and the beliefs that humans hold, addressing the limits of our ability to conceptualize or communicate with intelligent aliens and the scientific and philosophical implications of far-future evolutionary possibilities. Rich in personal and often amusing anecdotes, Lonely Planets explores the shifting boundary between planetary science and natural philosophy, and reveals how the search for extraterrestrial life unites our spiritual and scientific quests for connection with the cosmos. Includes a new foreword about recent Mars discoveries “An outstanding introduction to cosmic evolution.” —San Jose Mercury News “[A] terrific book.” —San Diego Union-Tribune “A personable chat on life, the universe and everything.” —Publishers Weekly
