Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive encyclopedia serves the needs of biomedical researchers, space mission planners and engineers, aerospace medicine physicians, graduate students, and professors interested in obtaining an up-to-date and readable introduction to bioastronautics, the science of humans in space. Following the excitement and progress of the birth of the space age in the fifties and sixties, with the successes in human space flight – culminating with the Moon landings – the field of bioastronautics retreated into the more workmanlike arena of successively longer stays in low Earth orbit. At this time, major new initiatives are ahead both in human and robotic space exploration. The International Space Station, along with the developing Chinese space station and lunar program, will permit the development and testing of the means of astronaut protection for long duration missions – eventually to Mars and its moons, as well as visits to asteroids, other NEOs, and the Lagrange points. New life support systems and innovative approaches to radiation protection beyond Earth’s magnetic field will all be developed and tested. Meanwhile, the search for extraterrestrial life, past or even present, is accelerating – with the spectacular finds of Martian water and the discovery of potentially habitable extra-solar planets. A new generation of scientists is ready to attack a new set of problems, and is in need of an efficient, accurate and searchable means of discovering the essentials of the field. This reference work also covers the challenges, past achievements, and potential solutions inherent to the safe exploration of distant space and the search for life off our planet. The entries summarize the tertiary literature and include sufficient data and illustrations to introduce each topic, while avoiding the length and detail of scientific review articles.

Download or read book Astronaut Extravehicular Activity written by Roedolph Adriaan Opperman and published by . This book was released on 2010 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extravehicular Activity (EVA) spacesuits are a key enabling technology which allow astronauts to survive and work in the harsh environment of space. Of the entire spacesuit, the gloves may perhaps be considered the most difficult engineering design issue. A significant number of astronauts sustain hand and shoulder injuries during extravehicular activity (EVA) training and operations. In extreme cases these injuries lead to fingernail delamination (onycholysis) or rotator cuff tears and require medical or surgical intervention. In an effort to better understand the causal mechanisms of injury, a study consisting of modeling, statistical and experimental analyses was performed in section I of this thesis. A cursory musculoskeletal modeling tool was developed for use in comparing various spacesuit hard upper torso designs. The modeling effort focuses on optimizing comfort and range of motion of the shoulder joint within the suit. The statistical analysis investigated correlations between the anthropometrics of the hand and susceptibility to injury. A database of 192 male crewmembers' injury records and anthropometrics was sourced from NASA's Johnson Space Center. Hand circumference and width of the metacarpophalangeal (MCP) joint were found to be significantly associated with injuries by the Kruskal-Wallis test. Experimental testing was conducted to characterize skin blood flow and contact pressure inside the glove. This was done as part of NASA's effort to evaluate a hypothesis that fingernail delamination is caused by decreasing blood flow in the finger tips due to compression of the skin inside the extravehicular mobility unit (EMU) glove. The initial investigation consisted of a series of skin blood flow and contact pressure tests of the bare finger, and showed that blood flow decreased to approximately 60% of baseline value with increasing force, however, this occurred more rapidly for finger pads (4N) than for finger tips (ION). A gripping test of a pressure bulb using the bare hand was also performed at a moderate pressure of 13.33kPa (100mmHg) and at a high pressure of 26.66kPa (200mmHg), and showed that blood flow decreased 50% and 45%, respectively. Excessive hyperperfusion was observed for all tests following contact force or pressure, which may also contribute to the onset of delamination. Preliminary data from gripping tests inside the EMU glove in a hypobaric chamber at NASA's Johnson Space Center show that skin blood flow decreased by 45% and 40% when gripping at 3 moderate and high pressures, respectively. These tests show that finger skin blood flow is significantly altered by contact force/pressure, and that occlusion is more sensitive when it is applied to the finger pad than the finger tip. Our results indicate that the pressure on the finger pads required to articulate stiff gloves is more likely to impact blood flow than the pressure on the fingertips associated with tight or ill-fitting gloves. Improving the flexibility of the gloves will therefore not only benefit operational performance, but may also be an effective approach in reducing the incidence of finger injury. Space Policy Abstract EVA injury is only one of many dangers astronauts face in the extreme environment of space. Orbital debris presents a significant threat to astronaut safety and is a growing cause of concern. Since the dawn of satellites in the early 1950's, space debris from intentionally exploded spacecraft, dead satellites, and on-orbit collisions has significantly increased and currently outnumbers operational space hardware. Adding to this phenomenon, the advent of commercial spaceflight and the recent space activities in China and India to establish themselves as spacefairing nations are bound to accelerate the rate of space debris accumulating in low Earth orbit, thus, exacerbating the problem. The policies regulating orbital debris were drafted in the 1960s and 1970s and fail to effectively address the dynamic nature of the debris problem. These policies are not legally enforced under international law and implementation is entirely voluntary. Space debris is a relevant issue in international space cooperation. Unless regulated, some projections indicate space debris will reach a point of critical density, after which the debris will grow exponentially, as more fragments are generated by collisions than are removed by atmospheric drag. Space debris proliferation negatively impacts human spaceflight safety, presents a hazard to orbiting space assets, and may lead to portions of near-Earth orbit becoming inaccessible, thus limiting mission operations. The aim of this research effort was to review current international space policy, legislation and mitigation strategies in light of two recent orbital collision episodes. The first is the February 2009 collision between a defunct Russian Cosmos spacecraft and a commercial Iridium satellite. The second is China's display of technological prowess during the January 2007 intentional demolition of its inactive Fengyun-IC weather satellite using a SC-19 antisatellite (ASAT) missile. In each case the stakeholders, politics, policies, and consequences of the collision are analyzed. The results of this analysis as well as recommendations for alternative mitigation and regulatory strategies are presented.

Available in PDF, EPUB and Kindle. Book excerpt: Safe Passage: Astronaut Care for Exploration Missions sets forth a vision for space medicine as it applies to deep space voyage. As space missions increase in duration from months to years and extend well beyond Earth's orbit, so will the attendant risks of working in these extreme and isolated environmental conditions. Hazards to astronaut health range from greater radiation exposure and loss of bone and muscle density to intensified psychological stress from living with others in a confined space. Going beyond the body of biomedical research, the report examines existing space medicine clinical and behavioral research and health care data and the policies attendant to them. It describes why not enough is known today about the dangers of prolonged travel to enable humans to venture into deep space in a safe and sane manner. The report makes a number of recommendations concerning NASA's structure for clinical and behavioral research, on the need for a comprehensive astronaut health care system and on an approach to communicating health and safety risks to astronauts, their families, and the public.

Available in PDF, EPUB and Kindle. Book excerpt: As the National Aeronautics and Space Administration (NASA) retires the Space Shuttle and shifts involvement in International Space Station (ISS) operations, changes in the role and requirements of NASA's Astronaut Corps will take place. At the request of NASA, the National Research Council (NRC) addressed three main questions about these changes: what should be the role and size of Johnson Space Center's (JSC) Flight Crew Operations Directorate (FCOD); what will be the requirements of astronaut training facilities; and is the Astronaut Corps' fleet of training aircraft a cost-effective means of preparing astronauts for NASA's spaceflight program? This report presents an assessment of several issues driven by these questions. This report does not address explicitly the future of human spaceflight.

Download or read book Human Spaceflight and Exploration written by Carol Norberg and published by Springer Science & Business Media. This book was released on 2013-11-18 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Architecture for Astronauts written by Sandra Häuplik-Meusburger and published by Springer Science & Business Media. This book was released on 2011-10-18 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Living and working in extra-terrestrial habitats means being potentially vulnerable to very harsh environmental, social, and psychological conditions. With the stringent technical specifications for launch vehicles and transport into space, a very tight framework for the creation of habitable space is set. These constraints result in a very demanding “partnership” between the habitat and the inhabitant. This book is the result of researching the interface between people, space and objects in an extra-terrestrial environment. The evaluation of extra-terrestrial habitats in comparison to the user’s perspective leads to a new framework, comparing these buildings from the viewpoint of human activity. It can be used as reference or as conceptual framework for the purpose of evaluation. It also summarizes relevant human-related design directions. The work is addressed to architects and designers as well as engineers.
