The key to opening the use of space to private enterprise and to broader public uses lies in reducing the cost of the transportation to space. More routine, affordable access to space will entail aircraft-like quick turnaround and reliable operations. Currently, the space Shuttle is the only reusable launch vehicle, and even parts of it are expendable while other parts require frequent and extensive refurbishment. NASA's highest priority new activity, the Reusable Launch Vehicle program, is directed toward developing technologies to enable a new generation of space launchers, perhaps but not necessarily with single stage to orbit capability. This book assesses whether the technology development, test and analysis programs in propulsion and materials-related technologies are properly constituted to provide the information required to support a December 1996 decision to build the X-33, a technology demonstrator vehicle; and suggest, as appropriate, necessary changes in these programs to ensure that they will support vehicle feasibility goals.

The purpose of this book is to share collective experience on human spaceflight operations. For the many authors, this is nothing less than a work of passion. They are sharing their life's work with the goal of passing on their experience to the next generation of space engineers, designers, operators, and crew.

Annotation Since the invention of the V-2 rocket during World War II, combustion instabilities have been recognized as one of the most difficult problems in the development of liquid propellant rocket engines. This book is the first published in the United States on the subject since NASA's Liquid Rocket Combustion Instability (NASA SP-194) in 1972. In this book, experts cover four major subject areas: engine phenomenology and case studies, fundamental mechanisms of combustion instability, combustion instability analysis, and engine and component testing. Especially noteworthy is the inclusion of technical information from Russia and China--a first.

The time of Carnival represents a "wild" time at the end of winter and pointing to the beginning of a new season. It is characterized by the irruption of border figures, animal masks, characters which recall the world of the dead and which bring within themselves the germ of a vital force, of the energy that produces the reawakening of nature and announces the growth and fertility of the new crops. This wild domain shows itself under the shapes of a contiguity between human and animal: the costumes, the masks, refer to a world in which the characteristics of the human and those of the animal are fused and intertwined. Among these figures, in particular, emerge those of the Wild Man, the human being who takes on animal-like attributes and aspects, and of the Bear, the animal that, more than all the others, gets as close as possible to the human and seems to reflect a deformed image of it. Such symbolic images come from far off times and places to tell a story that belongs to our common origins. The bear assumes attributes and functions alike in very different cultural contexts, such as the Sámi of Finland or North-American hunter-gatherers, and represents a boundary between the world of nature and the human world, between the domain of animals and the difficult construction of humanity: a process continued for centuries, perhaps millennia, and which cannot still be said complete.

This volume is the proceedings of the Atmospheric Flight Mechanics Conference, which took place in New Orleans, August 1997. It focuses on the technical progress, issues and challenges associated with atmospheric flight. Technical papers address stability and control, flying qualities (including one session dedicated to pilot-induced oscillations), unsteady and vortex aerodynamics, system and parameter identification, aircraft flight dynamic re-entry and aero assist technologies, and reusable launch vehicles.

The theory of natural pedagogy provides a model of social learning based on the direct communicative ostensive relation and aimed to the transfer of generic cultural knowledge. The pedagogical transmission of information originates from an explicit manifestation of teaching made by knowledgeable adults, who are naturally inclined to manifestly provide their cultural baggage to naïve conspecifics. The domain of transferable knowledge encompasses artifact functions, novel means actions, first words, gestural symbols, social practices, and rituals. This teaching process can be fast and efficient in virtue of a natural inclination possessed by infants to seek information and decode signals of ostensive communication. In this sense, the natural pedagogy represents, as the two proponents – György Gergey and Gergely Csibra – claim, «a communicative system of mutual design specialized for the fast and efficient transfer of new and relevant cultural knowledge from knowledgeable to ignorant conspecifics». This book suggests that natural pedagogy utilises early belief attribution competences, which are employed by infants in a variety of contexts to approach and navigate the social world. Therefore, the natural pedagogy, in cooperation with the early mindreading system, may represent one of the most efficient adaptive strategies to firmly create that deep wittgensteinian «nest of propositions» which build cultural shared beliefs structures to be relied upon and followed.

Space propulsion systems have a great influence on our ability to travel to other planets or how cheap a satellite can provide TV programs. This book provides an up-to-date overview of all kinds of propulsion systems ranging from classical rocket technology, nuclear propulsion to electric propulsion systems, and further to micro-, propellantless and even breakthrough propulsion, which is a new program under development at NASA. The author shows the limitations of the present concepts and how they could look like in the future. Starting from historical developments, the reader is taken on a journey showing the amazing technology that has been put on hold for decades to be rediscovered in the near future for questions like how we can even reach other stars within a human lifetime. The author is actively involved in advanced propulsion research and contributes with his own experience to many of the presented topics. The book is written for anyone who is interested in how space travel can be revolutionized.
