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.

Book Description
Higher education reforms have been on the agenda of Western European countries for 25 years, trying to deal with self governed professional bureaucracies politically weakened by massification when an emerging common understanding enhanced their role as major actors in knowledge based economies. While university systems are deeply embedded in national settings, the ex post rationale of still on-going reforms is surprisingly uniform and “de-nationalized”. They promote (1) the “organizational turn” of universities, to varying extent substituting collegial loosely coupled entities by “integrated, goal-oriented entities deliberately choosing their own actions (and therefore open to differentiation), that can thus be held responsible for what they do” (2) the diversification of stakeholders, supposedly offering solutions to problems as various as the democratisation of universities, the shrinking of State budget resources and the diversification of university missions offering answers to changes in the making and in the use of science. When it comes to accounting for these reforms, two grand narratives of public management share the floor. NPM implies a strengthening of the capacity of the core State to direct public services organizations through management by objectives and results or contractualization, assessment, evaluation and. “Governance” focuses on “network-based” governance systems, where coordinating power and control are collectively shared between the major ‘social actors or partners’ at all levels of the decision-making system. Our results suggest that all higher education systems under study were more or less transformed according to both these narratives. It is therefore needed to understand how they combine or create contradictions. This leads us to test a third neo-weberian model. This model reaffirms the role of the State, of representative democracy, (central, regional and local), of public law (suitably modernized), preserves the idea of a public service with a distinctive status, culture and terms and conditions. It shifts from an internal orientation to bureaucratic rules towards an external orientation in meeting citizens’ needs and wishes by means of standardization of work processes and their products, based on a distinctive public service and a particular legal order survived as the foundations beneath the various packages of modernizing reforms. This book traces the national dynamics of public policies, organizational design and steering tools in seven European higher education and research systems, using these narratives to interpret and test the actual changes and the degree of national specificities and European convergence. This book is not a sum of national chapters like other presumably comparative. It does not intend to tell once again the story of the transformation of the relationships between the state and universities. It tries to use Higher education system to discuss issues on state intervention and steering and more generally the NPM, governance and neo-weberian models in a specific field. Furthermore, this book intends breaking the walls between specialists in higher education and specialist in public management and research policy. This well rooted division of labour is less that ever justified as the university mission in research (fundamental, applied, strategic) is underscored by commentors and reformers themselves. For that reason, we have chosen to observe the consequences of the dynamics of public policies, organizational design and steering tools on two specific issues related to the development of research training and organizing within universities: the transformation of research funding on the one hand and the expansion of graduate studies and doctoral schools on the other.

Book Description
The 2014 Ukrainian crisis has highlighted the pro-Russia stances of some European countries, such as Hungary and Greece, and of some European parties, mostly on the far-right of the political spectrum. They see themselves as victims of the EU “technocracy” and liberal moral values, and look for new allies to denounce the current “mainstream” and its austerity measures. These groups found new and unexpected allies in Russia. As seen from the Kremlin, those who denounce Brussels and its submission to U.S. interests are potential allies of a newly re-assertive Russia that sees itself as the torchbearer of conservative values. Predating the Kremlin’s networks, the European connections of Alexander Dugin, the fascist geopolitician and proponent of neo-Eurasianism, paved the way for a new pan-European illiberal ideology based on an updated reinterpretation of fascism. Although Dugin and the European far-right belong to the same ideological world and can be seen as two sides of the same coin, the alliance between Putin’s regime and the European far-right is more a marriage of convenience than one of true love. This unique book examines the European far-right’s connections with Russia and untangles this puzzle by tracing the ideological origins and individual paths that have materialized in this permanent dialogue between Russia and Europe.

Book Description
In recent years, planetary science has seen a tremendous growth in new knowledge. Deposits of water ice exist at the Moon's poles. Discoveries on the surface of Mars point to an early warm wet climate, and perhaps conditions under which life could have emerged. Liquid methane rain falls on Saturn's moon Titan, creating rivers, lakes, and geologic landscapes with uncanny resemblances to Earth's. Vision and Voyages for Planetary Science in the Decade 2013-2022 surveys the current state of knowledge of the solar system and recommends a suite of planetary science flagship missions for the decade 2013-2022 that could provide a steady stream of important new discoveries about the solar system. Research priorities defined in the report were selected through a rigorous review that included input from five expert panels. NASA's highest priority large mission should be the Mars Astrobiology Explorer Cacher (MAX-C), a mission to Mars that could help determine whether the planet ever supported life and could also help answer questions about its geologic and climatic history. Other projects should include a mission to Jupiter's icy moon Europa and its subsurface ocean, and the Uranus Orbiter and Probe mission to investigate that planet's interior structure, atmosphere, and composition. For medium-size missions, Vision and Voyages for Planetary Science in the Decade 2013-2022 recommends that NASA select two new missions to be included in its New Frontiers program, which explores the solar system with frequent, mid-size spacecraft missions. If NASA cannot stay within budget for any of these proposed flagship projects, it should focus on smaller, less expensive missions first. Vision and Voyages for Planetary Science in the Decade 2013-2022 suggests that the National Science Foundation expand its funding for existing laboratories and establish new facilities as needed. It also recommends that the program enlist the participation of international partners. This report is a vital resource for government agencies supporting space science, the planetary science community, and the public.

Book Description
"To commemorate the 50th anniversary of the first successful planetary mission, Mariner 2 sent to Venus in 1962, the NASA History Program Office, the Division of Space History at the National Air and Space Museum, NASA's Science Mission Directorate, and the Jet Propulsion Laboratory organized a symposium. "Solar System Exploration @ 50" was held in Washington, D.C., on 25-26 October 2012. The purpose of this symposium was to consider, over the more than 50-year history of the Space Age, what we have learned about the other bodies of the solar system and the processes by which we have learned it. Symposium organizers asked authors to address broad topics relating to the history of solar system exploration such as various flight projects, the development of space science disciplines, the relationship between robotic exploration and human spaceflight, the development of instruments and methodologies for scientific exploration, as well as the development of theories about planetary science, solar system origins and implications for other worlds. The papers in this volume provide a richly textured picture of important developments - and some colorful characters - in a half century of solar system exploration. A comprehensive history of the first 50 years of solar system exploration would fill many volumes. What readers will find in this volume is a collection of interesting stories about money, politics, human resources, commitment, competition and cooperation, and the "faster, better, cheaper" era of solar system exploration"--
