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.

An Astrobiology Strategy for the Exploration of Mars

An Astrobiology Strategy for the Exploration of Mars PDF Author: National Research Council
Publisher: National Academies Press
ISBN: 9780309179416
Category : Science
Languages : en
Pages : 130

Book Description
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.

Planetary Astrobiology

Planetary Astrobiology PDF Author: Victoria Meadows
Publisher: University of Arizona Press
ISBN: 0816540063
Category : Science
Languages : en
Pages : 593

Book Description
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.

The Realities of 'Reality' - Part II: Making Sense of Why Modern Science Advances (Volume 2 of 2)

The Realities of 'Reality' - Part II: Making Sense of Why Modern Science Advances (Volume 2 of 2) PDF Author: Fritz Dufour, MBA, DESS
Publisher: Fritz Dufour
ISBN:
Category : Philosophy
Languages : en
Pages : 204

Book Description
The difference between Part I and Part II – Volumes 1 & 2 – of this series, is that in Part I the author showed how what we call reality starts with the inner self whereas Part II describes what, in fact, impacts and modifies the environment or reality and what are the factors behind that dynamics. What impacts and modifies the environment is science. This Volume 2 starts by showing how technology plays an important role in scientific progress. Although the relationship between the two is symbiotic, science can exist without technology but technology desperately needs science. Military technology is an example of how technology can help science advance. Some military inventions end up having civilian use. Science being at the center of society, the book makes the case for the direct impact of such social sciences as politics and economics on the advancement of science. Politics, says the author, influences science because of uncertainty in science, and economics does it thanks to the availability of money to scholars and scientists for their research. On the other hand, government also influences scientific progress through regulations. The book gives cyberspace regulation as an example. Furthermore, by showing how art influences science, the author really argues for the polyfactorial aspect of scientific progress. In that line of thought, he goes on to also prove that factors such as skepticism, curiosity, and the quest for knowledge greatly influence the advancement of science. That, says the author, “is a ninety-degree turn … By ending Part two that way, I wanted to, somehow, link it to Part I, which argues that reality starts from within.”

Universal Life

Universal Life PDF Author: Alan Boss
Publisher: Oxford University Press
ISBN: 0190864079
Category : Science
Languages : en
Pages : 240

Book Description
After decades of painstaking planning, NASA's first dedicated exoplanet detection mission, the Kepler space telescope, was launched in 2009 from Cape Canaveral. Kepler began a years-long mission of looking for Earth-like planets amongst the millions of stars in the northern constellations of Lyra and Cygnus. Kepler's successful launch meant that it was only a matter of time before we would know just how many Earth-like planets exist in our galaxy. A revolution in thinking about our place in the universe was about to occur, depending on what Kepler found. Are earths commonplace or rare? Are we likely to be alone in the universe? Only Kepler could start to answer these vexing questions. Universal Life provides a unique viewpoint on the epochal events of the last two decades and the excitement of what will transpire in the coming decades. Author Alan Boss's perspective on this story is unmatched. Boss is the Chair of NASA's Exoplanet Exploration Program Analysis Group, and was also on the Kepler Mission science team. Kepler proved that essentially every star in the night sky has a planetary system, and that most of these systems contain a habitable world, potentially capable of evolving and supporting life. Universal Life summarizes the current state of exoEarth knowledge, and also reveals what will happen next in the post-Kepler world, namely the narrowing of the search for habitable worlds to the stars that are the closest to Earth, those that offer the best chances for future ground- and space-based telescopes to search for, and detect, possible signs of life in their atmospheres. We have come far in the search for life beyond the Earth, but the most exciting phase is about to begin: we may soon be able to prove that we are not alone in the universe.

Review and Assessment of Planetary Protection Policy Development Processes

Review and Assessment of Planetary Protection Policy Development Processes PDF Author: National Academies of Sciences, Engineering, and Medicine
Publisher: National Academies Press
ISBN: 0309478650
Category : Science
Languages : en
Pages : 139

Book Description
Protecting Earth's environment and other solar system bodies from harmful contamination has been an important principle throughout the history of space exploration. For decades, the scientific, political, and economic conditions of space exploration converged in ways that contributed to effective development and implementation of planetary protection policies at national and international levels. However, the future of space exploration faces serious challenges to the development and implementation of planetary protection policy. The most disruptive changes are associated with (1) sample return from, and human missions to, Mars; and (2) missions to those bodies in the outer solar system possessing water oceans beneath their icy surfaces. Review and Assessment of Planetary Protection Policy Development Processes addresses the implications of changes in the complexion of solar system exploration as they apply to the process of developing planetary protection policy. Specifically, this report examines the history of planetary protection policy, assesses the current policy development process, and recommends actions to improve the policy development process in the future.
