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.
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 document communicates NASA’s strategy and progress to learn about the Red Planet, to inform us more about our Earth’s past and future, and may help answer whether life exists beyond our home planet. Together with NASA’s partners in academia and commercial enterprises, NASA’s vision is to pioneer Mars and answer some of humanity’s fundamental questions: • Was Mars home to microbial life? Is it today? • Could it be a safe home for humans one day? • What can it teach us about life elsewhere in the cosmos or how life began on Earth? • What can it teach us about Earth’s past, present, and future?
From September 2007 to June 2008 the Space Studies Board conducted an international public seminar series, with each monthly talk highlighting a different topic in space and Earth science. The principal lectures from the series are compiled in Forging the Future of Space Science. The topics of these events covered the full spectrum of space and Earth science research, from global climate change, to the cosmic origins of life, to the exploration of the Moon and Mars, to the scientific research required to support human spaceflight. The prevailing messages throughout the seminar series as demonstrated by the lectures in this book are how much we have accomplished over the past 50 years, how profound are our discoveries, how much contributions from the space program affect our daily lives, and yet how much remains to be done. The age of discovery in space and Earth science is just beginning. Opportunities abound that will forever alter our destiny.
This publication shares the successes of the International Space Station (ISS) in this second edition of the International Space Station Benefits for Humanity. The ISS is a unique scientific platform that has existed since 1998. The tremendous value of the ISS began through the engineering achievement evolving over a decade. Components were built in various countries around the world-all without the benefit of prior ground testing-allowing us to learn a vast amount about construction and about how humans and spacecraft systems function in orbit. This testament to the international achievement exemplifies cultural harmonization through cooperative teamwork leading to an international partnership that has continued to flourish and foster international cooperation. While each ISS partner has distinct agency goals for research conducted, a unified goal exists to extend the knowledge gleaned to benefit all humankind. In the first edition of the book released in 2012, the scientific, technological and educational accomplishments of ISS research that have an impact on life on Earth were summarized through a compilation of stories. The many benefits being realized were primarily in the areas of human health, Earth observations and disaster response, and global education. This second edition includes updated statistics on the impacts of those benefits as well as new benefits that have developed since the first publication. In addition, two new sections have been added to the book: Economic Development of Space and Innovative Technology. Economic Development of Space highlights case studies from public-private partnerships that are leading to a new economy in low-Earth orbit (LEO). Businesses provide both transportation to the ISS as well as some research facilities and services. These relationships promote a paradigm shift of government-funded, contractor-provided goods and services to commercially-provided goods purchased by government agencies. Other examples include commercial firms spending their research and development dollars to conduct investigations on ISS and commercial service providers selling services directly to ISS users. This section provides examples of the use of ISS as a testbed for new business relationships and illustrates successful partnerships. The second new section, Innovative Technology, merges technology demonstration and physical science findings that promise to return Earth benefits through continued research. Examples include robotic refueling concepts for life extensions of costly satellites in geo-synchronous orbit that have applications to the robotics industry on Earth, flame behavior experiments that reveal insight into how fuel burns in microgravity leading to the possibility of improving engine efficiency on Earth, and nanostructures and smart fluids examples of materials improvements that are being developed using data from ISS. This publication also expands the benefits of research results in human health, environmental change and disaster response and in education activities developed to capture student imaginations in support of Science, Technology, Engineering and Mathematics, or STEM, education, internationally. Applications to human health of the knowledge gained on ISS continue to grow and improve healthcare technologies and our understanding of human physiology. The ISS is a stepping stone for future space exploration, as the only orbiting multi-disciplinary laboratory of its kind returning research results that develop LEO and improve life on our planet. The goal of this publication is to serve as a source of pride to those who read it and learn of the unique shared laboratory orbiting our planet that provides ground for critical technologies and ways to keep humans healthy in space.
Space has become increasingly crowded since the end of the Cold War, with new countries, companies, and even private citizens operating satellites and becoming spacefarers. This book offers general readers a valuable primer on space policy from an international perspective. It examines the competing themes of space competition and cooperation while providing readers with an understanding of the basics of space technology, diplomacy, commerce, science, and military applications. The recent expansion of human space activity poses new challenges to existing treaties and other governance tools for space, increasing the likelihood of conflict over a diminishing pool of beneficial locations and resources close to Earth. Drawing on more than twenty years of experience in international space policy debates, James Clay Moltz examines possible avenues for cooperation among the growing pool of space actors, considering their shared interests in space traffic management, orbital debris control, division of the radio frequency spectrum, and the prevention of military conflict. Moltz concludes with policy recommendations for enhanced international collaboration in space situational awareness, scientific exploration, and restraining harmful military activities.
Progress in space safety lies in the acceptance of safety design and engineering as an integral part of the design and implementation process for new space systems. Safety must be seen as the principle design driver of utmost importance from the outset of the design process, which is only achieved through a culture change that moves all stakeholders toward front-end loaded safety concepts. This approach entails a common understanding and mastering of basic principles of safety design for space systems at all levels of the program organisation.
