This book was released on 2012-01-30 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than four decades have passed since a human first set foot on the Moon. Great strides have been made in our understanding of what is required to support an enduring human presence in space, as evidenced by progressively more advanced orbiting human outposts, culminating in the current International Space Station (ISS). However, of the more than 500 humans who have so far ventured into space, most have gone only as far as near-Earth orbit, and none have traveled beyond the orbit of the Moon. Achieving humans' further progress into the solar system had proved far more difficult than imagined in the heady days of the Apollo missions, but the potential rewards remain substantial. During its more than 50-year history, NASA's success in human space exploration has depended on the agency's ability to effectively address a wide range of biomedical, engineering, physical science, and related obstacles-an achievement made possible by NASA's strong and productive commitments to life and physical sciences research for human space exploration, and by its use of human space exploration infrastructures for scientific discovery. The Committee for the Decadal Survey of Biological and Physical Sciences acknowledges the many achievements of NASA, which are all the more remarkable given budgetary challenges and changing directions within the agency. In the past decade, however, a consequence of those challenges has been a life and physical sciences research program that was dramatically reduced in both scale and scope, with the result that the agency is poorly positioned to take full advantage of the scientific opportunities offered by the now fully equipped and staffed ISS laboratory, or to effectively pursue the scientific research needed to support the development of advanced human exploration capabilities. Although its review has left it deeply concerned about the current state of NASA's life and physical sciences research, the Committee for the Decadal Survey on Biological and Physical Sciences in Space is nevertheless convinced that a focused science and engineering program can achieve successes that will bring the space community, the U.S. public, and policymakers to an understanding that we are ready for the next significant phase of human space exploration. The goal of this report is to lay out steps and develop a forward-looking portfolio of research that will provide the basis for recapturing the excitement and value of human spaceflight-thereby enabling the U.S. space program to deliver on new exploration initiatives that serve the nation, excite the public, and place the United States again at the forefront of space exploration for the global good.

This book was released on 2000-07-03 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: The frontier represented by the near solar system confronts humanity with intriguing challenges and opportunities. With the inception of the Human Exploration and Development of Space (HEDS) enterprise in 1995, NASA has acknowledged the opportunities and has accepted the very significant challenges. Microgravity Research in Support of Technologies for the Human Exploration and Development of Space and Planetary Bodies was commissioned by NASA to assist it in coordinating the scientific information relevant to anticipating, identifying, and solving the technical problems that must be addressed throughout the HEDS program over the coming decades. This report assesses scientific and related technological issues facing NASA's Human Exploration and Development of Space endeavor, looking specifically at mission enabling and enhancing technologies which, for development, require an improved understanding of fluid and material behavior in a reduced gravity environment.

Download or read book Handbook of Life Support Systems for Spacecraft and Extraterrestrial Habitats written by Erik Seedhouse and published by Springer. This book was released on 2016-05-09 with total page 1200 pages. Available in PDF, EPUB and Kindle. Book excerpt: This reference work gathers all of the latest technologies, information, definitions and explanations of spacecraft life support systems, while providing in-depth coverage of the current knowledge of the business of keeping astronauts alive during their missions. It is intended that this MRW be the go-to reference work not only for aerospace engineers, but also for graduate and undergraduate aerospace engineers and space scientists. The area of spacecraft life support is comprised of dozens of specialties and sub-specialties within the fields of engineering, biophysics, and medicine. As space agencies around the world pursue cutting-edge life support technologies, much more information and data is accumulated. When humans move out into the solar system to stay for long durations, the most immediate challenge will be the provision of reliable and robust life support systems in locations devoid of food, air, and water. These life support systems must provide these commodities in each phase of spaceflight, including intra-vehicular activity (IVA) and extra-vehicular activity (EVA). Systems supporting human life must also fulfill myriad requirements: exceptional reliability in the space environment, allowing maintenance and component replacement in space; reduced resupply mass of consumables and spares; the ability to utilize local planetary resources for self sufficiency; and minimized mass power and volume requirements. These requirements will assume ever greater importance as bolder missions are envisioned and more sophisticated life support systems are required. For example, the next decade could see human missions to Mars and a return to the Moon. In the not-so-distant future, there is the prospect of Mars One and the creation of a permanent extraterrestrial colony. It may appear that a suitable environment can be created simply by reproducing terrestrial environmental conditions within a vehicle. In reality, it is first necessary to define the environmental characteristics humans require and match these requirements with the myriad design constraints. This is no easy task, because implementing these environmental parameters within a spacecraft can be challenging, while balancing the various requirements and constraints can test the abilities of even the most gifted aerospace engineer. Yet it is a crucial field of study and the experts contributing to this volume are on the very front lines.
Download or read book Fluid Mechanics and Tankage Design for Low Gravity Environments written by Robert G. Clodfelter and published by . This book was released on 1963 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electric propulsion systems for space vehicles must be able to restart and operate at zero and low gravity. This operation can be achieved if the tankage delivers only single-phase propellants. The requirements for feed systems of electric engines are described briefly. Also, the 1.85-second drop- test facility is described and the testing techniques are discussed. The minimum energy principle is presented along with a method for determining the direction of mass transfer in tapered tubes and liquid-vapor interface shapes in an annular space between concentric cylinders. Possible feed systems for electric engines are given, which utilize surface tension for fluid positioning and transfer. Zero-gravity and static-fluid configurations in cylindrical and spherical containers are discussed along with experimental observations. The interface 'overshoot' of the equilibrium zero-gravity configuration is also discussed.
Download or read book Pulling G written by Erik Seedhouse and published by Springer Science & Business Media. This book was released on 2012-09-26 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Performing in a high G environment is extremely demanding on the body: pulling G forces blood to the body’s extremities, putting the pilot, astronaut or driver at risk of G-Induced Lack of Consciousness (G-LOC). In “Pulling G” Erik Seedhouse describes what it feels like to pull 7 G in a fighter plane and the G pressures on the body when driving a Formula 1 car and many other gravity-defying vehicles. The book relates, for the first time, the effects of G in both hyper-gravity and microgravity. It describes the human response to increased and decreased G and the potentially dangerous effects of high G, with particular reference to dynamic injuries sustained in high acceleration environments. “Pulling G” provides an overview of G-related research and the development of intervention methods to mitigate the effects of increased and reduced G. As well as relating the training required to overcome G-forces on the Formula 1 track, Erik Seedhouse looks at the G forces encountered in such G environments as ejection from an aircraft, launch/re-entry, and zero-G. The book also considers how artificial gravity can be used to prevent bone demineralization and to reduce the effects of de-conditioning in astronauts. Erik Seedhouse is eminently qualified to describe the effects of large accelerations on the body. In addition to being the author of several previously published Springer Praxis books, he has developed astronaut-training protocols and is the training director for Astronauts for Hire (A4H). He is also the Canadian Forces’ High Risk Acceleration Training Officer.
Download or read book A Peacebuilding Tool for a Conflict Sensitive Approach to Development written by Asian Development Bank and published by Asian Development Bank. This book was released on 2012-03-01 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Asian Development Bank (ADB) works with a number of developing member countries facing fragile and conflict-affected situations---circumstances that complicate economic development, and might include domestic or international conflict, ethnic tensions, vulnerability to natural disasters, or a confluence of these factors. ADB piloted the peacebuilding tool in Nepal as a conflict-sensitive approach, a key to effective and safe implementation of projects in the country's post-conflict context. The peacebuilding tool is an analytical tool for assisting project team leaders and social experts in understanding the local context, and in identifying potential risks to implementation of development projects that are linked to social conflicts, as well as in formulating mitigation measures for addressing these risks.

This book was released on 2022-09-01 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has been prepared under the auspice of the European Low Gravity Research Association (ELGRA). The main task of ELGRA is to foster the scientific community in Europe and beyond in conducting gravity and space-related research.This publication is dedicated to the science community, and especially to the next generation of scientists and engineers interested in space research and in the means to use Earth to reproduce the space environment. ELGRA provides a comprehensive description of space conditions and the means that have been developed on Earth to perform space environmental and (micro-) gravity related research. .The book covers ground-based research instruments and environments for both life and physical sciences research. It discusses the opportunities and limitations of protocols and instruments to compensate gravity or simulate microgravity, such as clinostats, random positioning machines, levitating magnets, electric fields, vibrations, tail suspension or head down tilt, as well as centrifuges for hyper-g studies. Other space environmental conditions are addressed too, like cosmic radiation or Mars atmospheric and soil properties to be replicated and simulated on Earth. Future long duration of manned missions, personal well-being and crew interaction are major issues dealt with.
