多尔丹加任欧空局局长

欧空局6月17日宣布，现任局长让一雅克·多尔丹已再次当选，任期4年，2015年6月期满。这将是他的第三个任期。在多尔丹看来，除眼下欧洲各国政府预算削减的难题外，欧空局还面临一项挑战。即如何发展与欧盟委员会的关系。欧空局现为一个独立的政府间组织。它最终是否将成为欧盟的一部分是一个很可能需要多年才能解决的问题之一，这任欧空局局长本来轮到由德国政府选定，但国政府未能落实其自己的候选人。

Effects of commercialisation in the European space sector

Space activities are evolving from publicly financed to commercial undertakings. In 2000, the 50% mark was reached in Europe and this figure shows a steadily increasing tendency. Reduced public funding and increased technical maturity in space technologies have been the major forces driving this commercialisation process. European industry has adapted itself to this new environment with a number of mergers over the last decade. Strategic alliances represent the second, current phase in this process in order to cope with the challenges of the global space sectors. Besides national space legislation, new regulatory frameworks, initiated by the European commission and the WTO, as well as an increasingly internationally oriented workforce will accelerate this commercialisation process.

Policy assessment of the impacts of remote-sensing technology

The successful innovation and diffusion of commercial satellite enterprises may soon encroach upon the military's historic predominance in remote-sensing capabilities. The increasing world demand for remote-sensing data and services and the forces of globalization have opened unprecedented opportunities for informational and technological trade for industrialized nations, while simultaneously creating a risk to both state security and individual privacy rights. Even as scientists and international trade advocates have sought technologies to bolster information flows, the intelligence and military communities have sought to restrict technological access in the interest of national security. The tension caused by concentrating power among various levels of government is an intrinsic part of democratic government; however, remote-sensing technologies could disrupt the balance between concentrated interests (federal government officials and agencies) and diffused interests (local governments and individual citizens). This paper aims to examine holistically the opposing forces underlying the development, diffusion, and use of remote-sensing technologies. The analysis reveals the dimensions of this problem and provides insight into the efficacy of various short- and long-term government policies.     

The essential role of human spaceflight

The question is: should the United States and nations at large pursue a human spaceflight program (and if so, why)? I offer an unwavering positive answer to this question, and state the reasons for it while considering the broad challenges and benefits of (human) spaceflight. Space exploration is a human activity that is intrinsically forward-looking, and as such, has positive potential. Both national and international space programs can galvanize the population, inspire the youth, foster job-creation, and motivate the existing workforce. The nature of the enterprises involved—their scale, novelty, and complexity—requires a steady and continuous upward progression toward greater societal, scientific and technological development. That is, in order to overcome the challenges of human spaceflight, progress is required. More to the point, the survival of humanity depends on expanding beyond the confines of our planet. Human spaceflight, in short, presents us with an opportunity to significantly advance the nation and the global community.     

The NASA Astrobiology Roadmap

The NASA Astrobiology Roadmap provides guidance for research and technology development across the NASA enterprises that encompass the space, Earth, and biological sciences. The ongoing development of astrobiology roadmaps embodies the contributions of diverse scientists and technologists from government, universities, and private institutions. The Roadmap addresses three basic questions: How does life begin and evolve, does life exist elsewhere in the universe, and what is the future of life on Earth and beyond? Seven Science Goals outline the following key domains of investigation: understanding the nature and distribution of habitable environments in the universe, exploring for habitable environments and life in our own solar system, understanding the emergence of life, determining how early life on Earth interacted and evolved with its changing environment, understanding the evolutionary mechanisms and environmental limits of life, determining the principles that will shape life in the future, and recognizing signatures of life on other worlds and on early Earth. For each of these goals, Science Objectives outline more specific high-priority efforts for the next 3-5 years. These 18 objectives are being integrated with NASA strategic planning.
