This book is a new look at one of the hottest topics in contemporary science, Dark Matter. It is the pioneering text dedicated to sterile neutrinos as candidate particles for Dark Matter, challenging some of the standard assumptions which may be true for some Dark Matter candidates but not for all. So, this can be seen either as an introduction to a specialized topic or an out-of-the-box introduction to the field of Dark Matter in general. No matter if you are a theoretical particle physicist, an observational astronomer, or a ground based experimentalist, no matter if you are a grad student or an active researcher, you can benefit from this text, for a simple reason: a non-standard candidate for Dark Matter can teach you a lot about what we truly know about our standard picture of how the Universe works.

This book contains the expanded lecture notes of the 32nd Saas-Fee Advanced Course. The three contributions present the central themes in modern research on the cold universe, ranging from cold objects at large distances to the physics of dust in cold clouds.

Since the publication of The New Science of Astrobiology in the year 2001 the first edition of the present book two significant events have taken place raising the subject from the beginning of the present century to its present maturity. Firstly, in 2001 the Galileo Mission still had two years to complete its task, which turned out to be an outstanding survey of the Jovian system, especially of its intriguing satellite Europa. Secondly, the Cassini Huygens Mission was still on its way to Saturn. Its present success has surpassed all expectations of ESA and NASA. Astrobiologists still did not know that Titan was the fifth body in the Solar System that possibly contained a water ocean (including the Earth and the three Galilean satellites other than Io). For these reasons the book includes overviews of the evolutionary and molecular biology that are necessary. There is a discussion of other sectors of culture that are the natural frontiers of astrobiology, especially the humanities."

Life in Space explores the many aspects and outcomes of NASA's research in life sciences, a little-understood endeavor that has often been overlooked in histories of the space agency. Maura Mackowski details NASA's work in this field from spectacular promises made during the Reagan era to the major new directions set by George W. Bush's Vision for Space Exploration in the early twenty-first century. At the first flight of NASA's space shuttle in 1981, hopes ran high for the shuttle program to achieve its potential of regularly transporting humans, cargo, and scientific experiments between Earth and the International Space Station. Mackowski describes different programs, projects, and policies initiated across NASA centers and headquarters in the following decades to advance research into human safety and habitation, plant and animal biology, and commercial biomaterials. Mackowski illuminates these ventures in fascinating detail by drawing on rare archival sources, oral histories, interviews, and site visits. While highlighting significant achievements and innovations such as space radiation research and the Neurolab Spacelab Mission, Mackowski reveals frustrations-lost opportunities, stagnation, and dead ends-stemming from frequent changes in presidential administrations and policies. For today's dreams of lunar outposts or long-term spaceflight to become reality, Mackowski argues, a robust program in space life sciences is essential, and the history in this book offers lessons to help prevent leaving more expectations unfulfilled.

The book presents a unique overview of activities in human spaceflight and exploration and a discussion of future development possibilities. It provides an introduction for the general public interested in space and would also be suitable for students at university. The book includes the basics of the space environment and the effects of space travel on the human body. It leads through the challenges of designing life support systems for spacecraft as wells as space suits to protect astronauts during extravehicular activities. Research being carried out by humans in Earth orbit is being brought into context to other forms of space exploration. Between the end of 2007 and May 2009 ESA, the European Space Agency, carried out an astronaut recruitment process. It was the first time that astronauts had been recruited newly to the corps since its creation in 1998 and the positions were open to citizens of all of the member states of ESA. Two of the contributors to this book participated in the selection process and hence contribute to a general discussion of how one carries out such a selection programme. The book concludes with one person's experience of flying aboard the space shuttle on a mission to map planet Earth, bringing together topics taken up in earlier parts of the book.

This publication presents the proceedings of ICPMSE-3, the third international conference on Protection of Materials and Structures from the Low Earth Orbit Space Environment, held in Toronto April 25-26, 1996. The conference was hosted and organized by Integrity Testing Laboratory Inc, (ITL), and held at the University of Toronto's Institute for Aerospace Studies (UTIAS), where ITL is located. Twenty industrial companies, seven wliversities and eight government agencies from Canada, USA, United Kingdom, France, Israel, Russia, Ukraine and the Netherlands were represented by over 55 participants indicating increasing international co-operation in this critical arena of protection of materials in space. Twenty-five speakers, world experts in their fields, delivered talks on a wide variety of topics on various aspects of material protection in space, Representatives from the Canadian, American, European and Israeli space agencies as well as from leading space research laboratories of major aerospace industries gathered at UTIAS to discuss the latest developments in the field of material and structure protection from the harsh space environment, These proceedings are organized into four sections: a) AONOV and Radiation Effects on Materials and Structures in the Leo Space Environment; b) Interaction of Matter with the LEO Environment; c) Large Scale Coating Process Developments for Protection in LEO; d) Synthesis and Modification of Materials and Surfaces for Protection in LEO, This is the third in our on-going series of bi-annual international space materials conferences wllich began in 1992 in Toronto.

Earth as an Evolving Planetary System, Fourth Edition discusses key topics dealing with the evolution and interaction through time of Earth's crust, mantle, core, atmosphere, hydrosphere, and biosphere. It addresses the questions of why Earth is unique among planets of the solar system, and how the various subsystems in the planet have interacted over 4.6 billion years in the habitable planet that we live on. This new edition includes over 100 new pages of material, data, and images and is a key reference for students and researchers in Earth and planetary sciences. Earth as an Evolving Planetary System, Fourth Edition includes new material that has become available since the third edition, including new sections on the Mid-lithosphere discontinuity, geoneutrinos, mantle oxidation, continental emergence, Earth cycles (new chapter) and recycling processes, the evolution of Earth from a stagnant lid to a plate tectonic regime, the controversy over how the continents have grown, when plate tectonics began, and exoplanets.

This textbook was inspired by an undergraduate elective course given on virtual organizations and technology. The instructor could not find a suitable text that covered both the organizational and technological aspects including examples based on today's industry. Other books were either too strategic or too technical for an audience of undergraduate business and technology students who were to use the book. But why was that the case? For the same reason that business and IT people in industry tended not to speak the same "language": indeed, the integration of technology into business strategy has been a recent occurrence, and traditional strategy issues have been decided too high in the organizational structure while technology was too detailed in tactical implementation. With the Internet and the advent of e-commerce, m-commerce, and c-commerce (and the other letters of the alphabet soon to follow), business and technology finally started to become closer, and the interest in technology as an enabler for strategic business decision-making evolved into a mainstream concept. How are we defining a virtual organization? Most definitions of the concept of virtual organizations start with stating that it is "a network between organisations or individuals . . . ". The Oxford Concise Dictionary defines 'virtual' as: "that is such/or practical purposes, though not in name or according to a strict definition. " An organization may be thought of as a number of individuals systematically united for some end or work.

Many new tests of gravity and, in particular, of Einstein's general relativity theory will be carried out in the near future: The Lense--Thirring effect and the equivalence principle will be tested in space; moreover, gravitational waves will be detected, and new atomic interferometers and clocks will be built for measurements in gravitational and inertial fields. New high-precision devices have made these experiments feasible. They will contribute to a better understanding of gravitational physics. Both experimental developments and the theoretical concepts are collected in this volume. Exhaustive reviews give an overall insight into the subject of experimental gravitation.

This book presents the most important and crucial problems of space automation in context of future exploration programs. These programs could involve such issues as space situational awareness program, planetary protection, exploitation of minerals, assembly, manufacturing, and search for new habitable location for next human generations. The future exploration of Space and related activities will involve robots. In particular, new autonomous robots need to be developed with high degree of intelligence. Such robots would make space exploration possible but also they would make space automation an important factor in variety of activities related to Space.

Long before the space race captured the world's attention, K. E. Tsiolkovskii first conceived of multi-stage rockets that would later be adapted as the basis of both the U.S. and Soviet rocket programs.
Often called the grandfather of Russian rocketry, this provincial scientist was even sanctioned by Stalin to give a speech from Red Square on May Day 1935, lauding the Soviet technological future while also dreaming and expounding on his own visions of conquering the cosmos. Later, the Khrushchev regime used him as a "poster boy" for Soviet excellence during its Cold War competition with the United States. Ironically, some revisionists have since pointed to such blatant promotion by the Communist Party in an attempt to downplay Tsiolkovskii's scientific contributions.
James T. Andrews explores the complexities of this man to show that Tsiolkovskii was much more than either a rocket inventor or a propaganda tool. He was a science popularizer, novelist, technical inventor, and visionary, whose science fiction writings included futuristic drawings of space stations long before they appeared on any engineer's drawing board.
Mining a myriad of Russian archives, Andrews produces not only a biographical account but also a study of Soviet technological propaganda, local science education, public culture in the 1920s and 1930s, and the cultural ramifications of space flight.

This volume contains five articles describing the mission and its instruments. The first paper, by the project scientist Richard C. Elphic and his colleagues, describes the mission objectives, the launch vehicle, spacecraft and the mission itself. This is followed by a description of LADEE's Neutral Mass Spectrometer by Paul Mahaffy and company. This paper describes the investigation that directly targets the lunar exosphere, which can also be explored optically in the ultraviolet. In the following article Anthony Colaprete describes LADEE's Ultraviolet and Visible Spectrometer that operated from 230 nm to 810 nm scanning the atmosphere just above the surface. Not only is there atmosphere but there is also dust that putatively can be levitated above the surface, possibly by electric fields on the Moon's surface. Mihaly Horanyi leads this investigation, called the Lunar Dust Experiment, aimed at understanding the purported observations of levitated dust. This experiment was also very successful, but in this case their discovery was not the electrostatic levitation of dust, but that the dust was raised by meteoroid impacts. This is not what had been expected but clearly is the explanation that best fits the data. Originally published in Space Science Reviews, Volume 185, Issue 1-4, 2014.

It is within the means of many nations to conduct or participate in cost-effective Earth observation missions. This study provides a definition of cost-effective Earth observation missions and information about background material and organizational support. It discusses cost drivers and provides advice on achieving cost-effective missions and discusses training and education. The conclusions and recommendations range from more general factors, which drive the small satellite mission activities, to visions of future cost-effective Earth observation missions. Complementary to large complex missions, small satellite missions have specific advantages: more frequent missions opportunities and therefore faster return of science and application data, a larger variety of missions and greater diversification of potential users; more rapid expansion of the technical and/or scientific knowledge base; greater involvement of local and small industry. This volume will prove to be a useful source of information to governments, space agencies, academia, and industry.

New Horizons: Reconnaissance of the Pluto-Charon System and the Kuiper Belt C. T. Russell Originally published in the journal Space Science Reviews, Volume 140, Nos 1-4, 1-2. DOI: 10. 1007/s11214-008-9450-0 (c) Springer Science+Business Media B. V. 2008 Exploration is mankind's imperative. Since the beginnings of civilization, men and women have not been content to build a wall around their settlements and stay within its con nes. They explored the land around them, climbed the mountains, and scanned the horizons. The boldest among them pushed exploration to the most distant frontiers of the planet. As a result, much of the Earth was inhabited well before the days of the renowned European - th th plorers of the 15 and 16 centuries. Exploration did not cease, after the circumnavigation of the globe; it continued to the present. Today explorers are going in new directions, not just east and west, north and south. They explore backward in time and upward in space. Arc- ology explores the shorter time scales, and geochemistry the longer time scales of geophy- cal events: asteroidal and cometary collisions, magnetic reversals, continental formation and more. However, on Earth we cannot go back inde nitely, for much of the evidence of the very earliest days has been lost.

Andrew F. Nagy Originally published in the journal Space Science Reviews, Volume 139, Nos 1-4. DOI: 10. 1007/s11214-008-9353-0 (c) Springer Science+Business Media B. V. 2008 Keywords Aeronomy The term "aeronomy" has been used widely for many decades, but its origin has mostly been lost over the years. It was introduced by Sydney Chapman in a Letter to the Editor, entitled "Some Thoughts on Nomenclature," in Nature in 1946 (Chapman 1946). In that letter he suggested that aeronomy should replace meteorology, writing that the word "meteor is now irrelevant and misleading." This proposal was apparently not received with much support so in a short note in Weather in 1953 Chapman (1953)wrote: "If, despite its obvious convenience of brevity in itself and its derivatives, it does not commend itself to aeronomers, I think there is a case for modifying my proposal so that instead of the word being used to signify the study of the atmosphere in general, it should be adopted with the restricted sense of the science of the upper atmosphere, for which there is no convenient short word. " In a chapter, he wrote in a 1960 book (Chapman 1960), he give his nal and de nitive de nition, by stating that "Aeronomy is the science of the upper region of the atmosphere, where dissociation and ionization are important." The Workshop on "Comparative Aeronomy" was held at ISSI during the week of June 25-29, 2007.

A new and detailed picture of Mercury is emerging thanks to NASA's MESSENGER mission that spent four years in orbit about the Sun's innermost planet. Comprehensively illustrated by close-up images and other data, the author describes Mercury's landscapes from a geological perspective: from sublimation hollows, to volcanic vents, to lava plains, to giant thrust faults. He considers what its giant core, internal structure and weird composition have to tell us about the formation and evolution of a planet so close to the Sun. This is of special significance in view of the discovery of so many exoplanets in similarly close orbits about their stars. Mercury generates its own magnetic field, like the Earth (but unlike Venus, Mars and the Moon), and the interplay between Mercury's and the Sun's magnetic field affects many processes on its surface and in the rich and diverse exosphere of neutral and charged particles surrounding the planet. There is much about Mercury that we still don't understand. Accessible to the amateur, but also a handy state-of-the-art digest for students and researchers, the book shows how our knowledge of Mercury developed over the past century of ground-based, fly-by and orbital observations, and looks ahead at the mysteries remaining for future missions to explore.

James L. Burch*C. Philippe Escoubet Originally published in the journal Space Science Reviews, Volume 145, Nos 1-2, 1-2. DOI: 10. 1007/s11214-009-9532-7 (c) Springer Science+Business Media B. V. 2009 The IMAGE and CLUSTER spacecraft have revolutionized our understanding of the inner magnetosphere and in particular the plasmasphere. Before launch, the plasmasphere was not a prime objective of the CLUSTER mission. In fact, CLUSTER might not have ever observed this region because a few years before the CLUSTER launch (at the beginning of the 1990s), it was proposed to raise the perigee of the orbit to 8 Earth radii to make multipoint measu- ments in the current disruption region in the tail. Because of ground segment constraints, this proposal did not materialize. In view of the great depth and breadth of plasmaspheric research and numerous papers published on the plasmasphere since the CLUSTER launch, this choice certainly was a judicious one. The fact that the plasmasphere was one of the prime targets in the inner magnetosphere for IMAGE provided a unique opportunity to make great strides using the new and comp- mentary measurements of the two missions. IMAGE, with sensitive EUV cameras, could for the rst time make global images of the plasmasphere and show its great variability d- ing storm-time. CLUSTER, with four-spacecraft, could analyze in situ spatial and temporal structures at the plasmapause that are particularly important in such a dynamic system.

Voted the Best Space Book of 2018 by the Space Hipsters The dramatic inside story of the epic search and recovery operation after the Columbia space shuttle disaster. On February 1, 2003, Columbia disintegrated on reentry before the nation's eyes, and all seven astronauts aboard were lost. Author Mike Leinbach, Launch Director of the space shuttle program at NASA's John F. Kennedy Space Center was a key leader in the search and recovery effort as NASA, FEMA, the FBI, the US Forest Service, and dozens more federal, state, and local agencies combed an area of rural east Texas the size of Rhode Island for every piece of the shuttle and her crew they could find. Assisted by hundreds of volunteers, it would become the largest ground search operation in US history. This comprehensive account is told in four parts: Parallel Confusion Courage, Compassion, and Commitment Picking Up the Pieces A Bittersweet Victory For the first time, here is the definitive inside story of the Columbia disaster and recovery and the inspiring message it ultimately holds. In the aftermath of tragedy, people and communities came together to help bring home the remains of the crew and nearly 40 percent of shuttle, an effort that was instrumental in piecing together what happened so the shuttle program could return to flight and complete the International Space Station. Bringing Columbia Home shares the deeply personal stories that emerged as NASA employees looked for lost colleagues and searchers overcame immense physical, logistical, and emotional challenges and worked together to accomplish the impossible. Featuring a foreword and epilogue by astronauts Robert Crippen and Eileen Collins, and dedicated to the astronauts and recovery search persons who lost their lives, this is an incredible, compelling narrative about the best of humanity in the darkest of times and about how a failure at the pinnacle of human achievement became a story of cooperation and hope.

Unlike other American astronauts, Virgil I. ""Gus""Grissom never had the chance to publish his memoirs. Killed along with his crewin a launch pad fire on January 27, 1967, Grissom also lost his chance to walkon the moon and return to describe his journey. Others went in his place. Thestories of the moon walkers are familiar. Less appreciated are Grissom'scontributions. The international prestige of winning the Moon Race cannotbe understated, and Grissom played a pivotal and enduring role in securing thatlegacy for the United States. Indeed, Grissom was first and foremost a ColdWarrior, a member of the first group of Mercury astronauts whose goal it was tobeat the Soviet Union into space and eventually to the moon. Drawing on extensive interviews with fellow astronauts, NASA engineers, family members, and friends of Gus Grissom, George Leopold deliversa comprehensive and corrective account of Grissom’s life that places his careerin the context of the Cold War and the history of human spaceflight. Calculated Risk: TheSupersonic Life and Times of Gus Grissom adds significantly to ourunderstanding of that tumultuous and ultimately triumphant period in American history.

NASA's Genesis mission, launched on August 8, 2001 is the fifth mission in the Discovery series. Genesis addresses questions about the materials and processes involved in the origin of the solar system by providing precise knowledge of solar isotopic and elemental compositions for comparison with the compositions of meteoritic and planetary materials. This book describes the Genesis mission, the solar wind collector materials, the solar wind concentrator and simulations of its performance, the plasma ion and electron instruments, and the way these two instruments are used to determine the solar wind flow regime on board the spacecraft. The book is of interest to all potential users of the data returned by the Genesis mission, to those studying the isotopic and chemical composition of the early solar system whose work will be influenced by the measurements made by Genesis and by all those interested in the design and implementation of space instruments to study space plasmas.

In the new space age after the end of the Cold War, orbit and frequency allocations, traffic control, safety, and a number of support services such as space weather forecast and orbital debris monitoring need to be coordinated transparently and effectively by clear rules at an international level. The establishment of an international civil space regulatory framework is the central theme of this book, in particular, the possible extension to space of the international regulatory framework model adopted for aviation more than 60 years ago with the establishment of the International Civil Aviation Organization (ICAO).

The book also highlights the increased reliance of aviation safety on space-based navigation and communication systems, the increasing space systems traffic through the international airspace under the jurisdiction of the ICAO, and the emerging hybrid systems such as aero-spacecraft and space planes, to advocate the practical benefits of directly expanding the ICAO Convention domain beyond the airspace to include outer space up to the geostationary orbits.
