Planetary Exploration Horizon 2061: A Long-Term Perspective for Planetary Exploration synthesizes all the material elaborated and discussed during three workshops devoted to the Horizon 2061 foresight exercise. Sections cover the science of planetary systems, space missions to solar system objects, technologies for exploration, and infrastructures and services to support the missions and to maximize their science return. The editors follow the path of the implementation of a planetary mission, from the needed support in terms of navigation and communication, through the handling of samples returned to Earth, to the development of more permanent infrastructures for scientific human outposts on the Moon and Mars.

This book also includes a special chapter entirely devoted to contributions from students and early-career scientists: the "Horizon 2061 generation� and a final chapter on important avenues for the actual implementation of the planetary missions coming out of our "Dreams for Horizon 2061�: International cooperation, and the growing role and initiatives of private enterprise in planetary exploration.

Provides a logical link between scientific questions and the technologies needed to thoroughly address them Organized chapters present a logical road map of subjects, while also stimulating a cross-disciplinary understanding of the scientific and technical challenges of planetary exploration Contains illustrations and tables that capture and synthesize knowledge of a broad readership

This title was first published in 2001. Focusing on the distinctive ways in which rural social, economic and political life is experienced in developed societies in late modernity, this striking volume draws on empirical material from a wide range of countries within and outside the EU. It also incorporates comparative case studies from South Africa, Australia and New Zealand.

Over the last fifteen years, space-based exploration of the solar system has increased dramatically, with more and more sophisticated orbiters and landers being sent to Mars. This intense period, rich in unprecedented scientific results, has led to immense progress in our perception of Mars and of its evolution over geological time. In parallel, advances in numerical simulations and laboratory experiments also shed new light on the geochemical evolution of the planet Mars. The ISSI-Europlanet Workshop entitled "Quantifying the Martian Geochemical Reservoirs" was held in Bern in April 2011 with the objective to create a diverse interdisciplinary forum composed of scientists directly involved in space-based exploration of the Martian surface, meteoriticists studying SNC meteorites, and planetary and/or Earth scientists simulating, numerically or experimentally, the physical and chemical processes occurring on or within Mars. The chapters of this book provide an overview of current knowledge of the past and present Martian geochemical reservoirs, from the accretionary history to the secondary alteration processes at the surface. In addition to the detailed description of data from Mars and the methods used to obtain them, the contributions also emphasize comparison with features on Earth, providing a perspective on the extent to which our knowledge of terrestrial systems influences interpretation of data from Mars. Areas that would benefit from future work and measurements are also identified, providing a view of the short-term and long-term future of the study of Mars.This collection of chapters constitutes a timely perspective on current knowledge and thinking concerning the geochemical evolution of Mars, providing context and a valuable reference point for even more exciting future discoveries. It is aimed at graduate students and researchers active in geochemistry and space science. Previouslypublished in Space Science Reviews, Vol. 174/1-4, 2013.

This volume discusses the evolutionary paths linking planets and their atmospheres to their origin within circumstellar disks. It reviews the main phases of this evolution, summarizes what we understand and what are the important open questions, and suggests ways towards solutions. Dust accretion within disks generates planet cores, while gas accretion on these cores leads to the diversity of their fluid envelopes. The formation of planetary proto-atmospheres and oceans is an essential product of planet formation. A fraction of the planets retain their primary proto-atmosphere, while others lose it and may form a “secondary” atmosphere. When the disk finally dissipates, it leaves us with the combination of a planetary system and a debris disk. Using the next generation of observing facilities, we will be able to reconstruct more accurately the evolutionary paths linking stellar genesis to the possible emergence of habitable worlds.Originally published in Space Science Reviews, Volume 205, Issue 1-4, December 2016

Liquid water is essential for the emergence of life at least as we know it on Earth. Written by recognized experts in the field, this volume provides a complete inventory of water throughout the Solar System and a comprehensive overview of the evolution of water from the interstellar medium to the final planetesimals and planets.Through a series of up-to-date review papers, the book describes how water influences the geophysical evolutions of bodies and how it is in turn affected by such evolutions. Processes like atmospheric escape under the effect of stellar irradiation and collisional impacts are discussed in detail, with specific emphasis on the consequences for the budgets of water and volatile elements in general. Specific papers on the emergence of life on Earth and the prospects of habitability on extrasolar planets are included.The papers take an interdisciplinary approach to habitability, addressing it from the perspectives of astronomy, planetary science, geochemistry, geophysics and biology. Comprehensive yet easy to read, this volume serves as an invaluable resource to scholarly, professional and general audiences alike.​Originally published in Space Science Reviews in the Topical Collection "The Delivery of Water to Protoplanets, Planets and Satellites"

This volume takes an interdisciplinary approach to the evolution of terrestrial planets, addressing the topic from the perspectives of planetary sciences, geochemistry, geophysics and biology, and solar and astrophysics.The review papers analyze the chemical, isotopic and elemental evolution of the early Solar System, with specific emphasis on Venus, Earth, and Mars. They discuss how these factors contribute to our understanding of accretion timescales, volatile delivery, the origin of the Moon and the evolution of atmospheres and water inventories of terrestrial planets. Also explored are plate tectonic formation, the origin of nitrogen atmospheres and the prospects for exoplanet habitability.The papers are forward-looking as well, considering the importance of future space missions for understanding terrestrial planet evolution in the Solar System and beyond. Overall, this volume shall be useful for academic and professional audiences across a range of scientific disciplines.Previously published in Space Science Reviews in the Topical Collection "Reading Terrestrial Planet Evolution in Isotopes and Element Measurements"

Thanks to the observation of a growing number of planetary atmospheres, we are at the dawn of a major scientific revolution in atmospheric and climate sciences. But are we ready to understand what will be discovered around other stars? This book brings together 15 review chapters that study and provide up-to-date information on the physical and chemical processes that control the nature of atmospheres. It identifies commonalities between various solar system atmospheres, analyzes the dynamic processes behind different atmospheric circulation regimes, and outlines key questions remaining in solar system science.Through this comprehensive overview, the volume will help researchers understand the possible nature of the exo-atmospheres to be discovered in the coming decades thanks to upcoming new generations of telescopes.Previously published in Space Science Reviews in the Topical Collection "Understanding the Diversity of Planetary Atmospheres”
