New Frontiers in Astrobiology
Author: Rebecca Thombre
Publisher: Elsevier
ISBN: 0323859275
Category : Science
Languages : en
Pages : 340
Book Description
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

Extreme Events in Geospace
Author: Natalia Buzulukova
Publisher: Elsevier
ISBN: 0128127015
Category : Science
Languages : en
Pages : 800
Book Description
Extreme Events in Geospace: Origins, Predictability, and Consequences helps deepen the understanding, description, and forecasting of the complex and inter-related phenomena of extreme space weather events. Composed of chapters written by representatives from many different institutions and fields of space research, the book offers discussions ranging from definitions and historical knowledge to operational issues and methods of analysis. Given that extremes in ionizing radiation, ionospheric irregularities, and geomagnetically induced currents may have the potential to disrupt our technologies or pose danger to human health, it is increasingly important to synthesize the information available on not only those consequences but also the origins and predictability of such events. Extreme Events in Geospace: Origins, Predictability, and Consequences is a valuable source for providing the latest research for geophysicists and space weather scientists, as well as industries impacted by space weather events, including GNSS satellites and radio communication, power grids, aviation, and human spaceflight. The list of first/second authors includes M. Hapgood, N. Gopalswamy, K.D. Leka, G. Barnes, Yu. Yermolaev, P. Riley, S. Sharma, G. Lakhina, B. Tsurutani, C. Ngwira, A. Pulkkinen, J. Love, P.

Volcanism and Tectonism Across the Inner Solar System
Author: T. Platz
Publisher: Geological Society of London
ISBN: 1862396329
Category : Science
Languages : en
Pages : 448
Book Description
Volcanism and tectonism are the dominant endogenic means by which planetary surfaces change. This book aims to encompass the broad range in character of volcanism, tectonism, faulting and associated interactions observed on planetary bodies across the inner solar system - a region that includes Mercury, Venus, Earth, the Moon, Mars and asteroids. The diversity and breadth of landforms produced by volcanic and tectonic processes is enormous, and varies across the inner solar system bodies. As a result, the selection of prevailing landforms and their underlying formational processes that are described and highlighted in this volume are but a primer to the expansive field of planetary volcanism and tectonism. This Special Publication features 22 research articles about volcanic and tectonic processes manifest across the inner solar system.

Book Description
The Earth has limited resources while the resources in space are virtually unlimited. Further development of humanity will require going beyond our planet and exploring of extraterrestrial bodies and their resources. This book investigates Outer Solar Systems and their prospective energy and material resources. It presents past missions and future technologies and solutions to old problems that could become reality in our life time. The book therefore is a great resource of condensed information for specialists interested in current and impending Outer Solar Systems related activities and a good starting point for space researchers, inventors, technologists and potential investors.

Recapturing a Future for Space Exploration
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309163846
Category : Science
Languages : en
Pages : 464
Book Description
More than four decades have passed since a human first set foot on the Moon. Great strides have been made in our understanding of what is required to support an enduring human presence in space, as evidenced by progressively more advanced orbiting human outposts, culminating in the current International Space Station (ISS). However, of the more than 500 humans who have so far ventured into space, most have gone only as far as near-Earth orbit, and none have traveled beyond the orbit of the Moon. Achieving humans' further progress into the solar system had proved far more difficult than imagined in the heady days of the Apollo missions, but the potential rewards remain substantial. During its more than 50-year history, NASA's success in human space exploration has depended on the agency's ability to effectively address a wide range of biomedical, engineering, physical science, and related obstacles-an achievement made possible by NASA's strong and productive commitments to life and physical sciences research for human space exploration, and by its use of human space exploration infrastructures for scientific discovery. The Committee for the Decadal Survey of Biological and Physical Sciences acknowledges the many achievements of NASA, which are all the more remarkable given budgetary challenges and changing directions within the agency. In the past decade, however, a consequence of those challenges has been a life and physical sciences research program that was dramatically reduced in both scale and scope, with the result that the agency is poorly positioned to take full advantage of the scientific opportunities offered by the now fully equipped and staffed ISS laboratory, or to effectively pursue the scientific research needed to support the development of advanced human exploration capabilities. Although its review has left it deeply concerned about the current state of NASA's life and physical sciences research, the Committee for the Decadal Survey on Biological and Physical Sciences in Space is nevertheless convinced that a focused science and engineering program can achieve successes that will bring the space community, the U.S. public, and policymakers to an understanding that we are ready for the next significant phase of human space exploration. The goal of this report is to lay out steps and develop a forward-looking portfolio of research that will provide the basis for recapturing the excitement and value of human spaceflight-thereby enabling the U.S. space program to deliver on new exploration initiatives that serve the nation, excite the public, and place the United States again at the forefront of space exploration for the global good.
