Book excerpt: 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.

Book Synopsis Imagining Outer Space by : Alexander C.T. Geppert

Download or read book Imagining Outer Space written by Alexander C.T. Geppert. This book was released on 2018-04-25. Available in PDF, EPUB and Kindle. Book excerpt: Imagining Outer Space makes a captivating advance into the cultural history of outer space and extraterrestrial life in the European imagination. How was outer space conceived and communicated? What promises of interplanetary expansion and cosmic colonization propelled the project of human spaceflight to the forefront of twentieth-century modernity? In what way has West-European astroculture been affected by the continuous exploration of outer space? Tracing the thriving interest in spatiality to early attempts at exploring imaginary worlds beyond our own, the book analyzes contact points between science and fiction from a transdisciplinary perspective and examines sites and situations where utopian images and futuristic technologies contributed to the omnipresence of fantasmatic thought. Bringing together state-of-the-art work in this emerging field of historical research, the volume breaks new ground in the historicization of the Space Age.

Book Synopsis Planetary Astrobiology by : Victoria Meadows

Download or read book Planetary Astrobiology written by Victoria Meadows. This book was released on 2020-07-07. Available in PDF, EPUB and Kindle. Book excerpt: Are we alone in the universe? How did life arise on our planet? How do we search for life beyond Earth? These profound questions excite and intrigue broad cross sections of science and society. Answering these questions is the province of the emerging, strongly interdisciplinary field of astrobiology. Life is inextricably tied to the formation, chemistry, and evolution of its host world, and multidisciplinary studies of solar system worlds can provide key insights into processes that govern planetary habitability, informing the search for life in our solar system and beyond. Planetary Astrobiology brings together current knowledge across astronomy, biology, geology, physics, chemistry, and related fields, and considers the synergies between studies of solar systems and exoplanets to identify the path needed to advance the exploration of these profound questions. Planetary Astrobiology represents the combined efforts of more than seventy-five international experts consolidated into twenty chapters and provides an accessible, interdisciplinary gateway for new students and seasoned researchers who wish to learn more about this expanding field. Readers are brought to the frontiers of knowledge in astrobiology via results from the exploration of our own solar system and exoplanetary systems. The overarching goal of Planetary Astrobiology is to enhance and broaden the development of an interdisciplinary approach across the astrobiology, planetary science, and exoplanet communities, enabling a new era of comparative planetology that encompasses conditions and processes for the emergence, evolution, and detection of life.
