This book was released on 2018-06-04 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary aim of this research effort was to advance the current understanding of astronauts' capabilities and limitations in space-suited EVA by developing models of the constitutive and compatibility relations of a space suit, based on experimental data gained from human test subjects as well as a 12 degree-of-freedom human-sized robot, and utilizing these fundamental relations to estimate a human factors performance metric for space suited EVA work. The three specific objectives are to: 1) Compile a detailed database of torques required to bend the joints of a space suit, using realistic, multi- joint human motions. 2) Develop a mathematical model of the constitutive relations between space suit joint torques and joint angular positions, based on experimental data and compare other investigators' physics-based models to experimental data. 3) Estimate the work envelope of a space suited astronaut, using the constitutive and compatibility relations of the space suit. The body of work that makes up this report includes experimentation, empirical and physics-based modeling, and model applications. A detailed space suit joint torque-angle database was compiled with a novel experimental approach that used space-suited human test subjects to generate realistic, multi-joint motions and an instrumented robot to measure the torques required to accomplish these motions in a space suit. Based on the experimental data, a mathematical model is developed to predict joint torque from the joint angle history. Two physics-based models of pressurized fabric cylinder bending are compared to experimental data, yielding design insights. The mathematical model is applied to EVA operations in an inverse kinematic analysis coupled to the space suit model to calculate the volume in which space-suited astronauts can work with their hands, demonstrating that operational human factors metrics can be predicted from fundamental space suit information.Newman, DavaJohnson Space CenterHUMAN FAC

Book Quantifying and Modelling Adaptive Astronaut Movement

Download or read book Quantifying and Modelling Adaptive Astronaut Movement written by Philip Andrew Ferguson and published by . This book was released on 2006 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: (Cont.) Forces and moments from the push-offs and landings were recorded using 6-axis force-moment sensors. Joint angles were measured using a kinematic video analysis system. A suite of dynamic estimation filters was written to combine the kinetic and kinematic data. Experimental results showed significant motor control adaptation to the air-bearing floor experiments, evidenced by reduced peak push-off forces and increased sensor contact times. A model based on Golgi tendon organ (GTO) force feedback was proposed to predict the observed adaptation. Comparisons between the experimental data and the model predictions indicate that the GTO adaptation model can adequately predict the observed adaptation.

Download or read book Safe Passage written by Institute of Medicine and published by National Academies Press. This book was released on 2001-11-20 with total page 317 pages. 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: In Psychology and Human Performance in Space Programs: Research at the Frontier, leading space researchers from multiple fields of expertise summarize the recent growth of knowledge, the resulting tools and techniques, and the research still needed to protect humans in space. Making use of cutting-edge research and development related to composing, training, and supporting astronaut crews who will live and work together for future missions to Mars, this book examines the current practices of leaders in the field both at NASA and in academia. Presenting astronaut data alongside data from analogous extreme environments such as mission simulation habitats, this volume helpfully contrasts and compares to examine the lessons that can be learned from other approaches. Using the context of current International Space Station missions, the book discusses the influence of human factors and physiological health on individual and team job performance and social cohesion. With an overview of the physical and psychological hazards of space, and the challenges posed by conducting space-related applied psychology research, this volume uses the context of a long-duration Mars mission as a lens through which to discuss adaptation and resilience, technical and team training, technological advances related to working and living in space, and human interaction with onboard systems. Additionally, the book includes an essay from retired astronaut Clay Anderson on his experiences in space and thoughts on future missions to the moon and Mars. This first of two volumes will be of interest to professionals in the field of human factors and psychology at work, as well as academics examining human performance in extreme environments and aerospace.

Book Recapturing a Future for Space Exploration

Download or read book Recapturing a Future for Space Exploration written by National Research Council and published by National Academies Press. 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 2012-12-06 with total page 944 pages. Available in PDF, EPUB and Kindle. Book excerpt: A NATO Advanced Study Institute (ASI) on the Behavior of Systems in the Space Environment was held at the Atholl Palace Hotel, Pitlochry, Perthshire, Scotland, from July 7 through July 19, 1991. This publication is the Proceedings of the Institute. The NATO Advanced Study Institute Program of the NATO Science Committee is a unique and valuable forum, under whose auspices almost one thousand international tutorial meetings have been held since the inception of the program in 1959. The ASI is intended to be primarily a high-level teaching activity at which a carefully defined subject is presented in a systematic and coherently structured program. The subject is treated in considerable depth by lecturers eminent; in their :(ield and of international standing. The subject is presented to other scientists who either will already have specialized in the field or possess an advanced general background. The ASI is aimed at approximately the post-doctoral level. This ASI emphasized the basic physics of the space environment and the engineering aspects of the environment's interactions with spacecraft.

Book Technical Evaluation of the NASA Model for Cancer Risk to Astronauts Due to Space Radiation

Download or read book Technical Evaluation of the NASA Model for Cancer Risk to Astronauts Due to Space Radiation written by National Research Council and published by National Academies Press. This book was released on 2012-04-19 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: NASA's current missions to the International Space Station (ISS) and potential future exploration missions involving extended stays by astronauts on the lunar surface, as well as the possibility of near- Earth object (NEO) or Mars missions, present challenges in protecting astronauts from radiation risks. These risks arise from a number of sources, including solar particle events (SPEs), galactic cosmic rays (GCRs), secondary radiation from surface impacts, and even the nuclear isotope power sources transported with the astronauts. The serious early and late radiation health effects potentially posed by these exposures are equally varied, ranging from early signs of radiation sickness to cancer induction. Other possible effects include central nervous system damage, cataracts, cardiovascular damage, heritable effects, impaired wound healing, and infertility. Recent research, much of which has been sponsored by NASA, has focused on understanding and quantifying the radiation health risks posed by space radiation environments. Although many aspects of the space radiation environments are now relatively well characterized, important uncertainties still exist regarding biological effects and thus regarding the level and types of risks faced by astronauts. This report presents an evaluation of NASA's proposed space radiation cancer risk assessment model, which is described in the 2011 NASA report, Space Radiation Cancer Risk Projections and Uncertainties-2010. The evaluation in Technical Evaluation of the NASA Model for Cancer Risk to Astronauts Due to Space Radiation considers the model components, input data (for the radiation types, estimated doses, and epidemiology), and the associated uncertainties. This report also identifies gaps in NASA's current research strategy for reducing the uncertainties in cancer induction risks.
