Bounding the Spacecraft Atmosphere Design Space for Future Exploration Missions by National Aeronautics and Space Adm Nasa Pdf
The selection of spacecraft and space suit atmospheres for future human space exploration missions will play an important, if not critical, role in the ultimate safety, productivity, and cost of such missions. Internal atmosphere pressure and composition (particularly oxygen concentration) influence many aspects of spacecraft and space suit design, operation, and technology development. Optimal atmosphere solutions must be determined by iterative process involving research, design, development, testing, and systems analysis. A necessary first step in this process is the establishment of working bounds on the atmosphere design space.Lange, Kevin E. and Perka, Alan T. and Duffield, Bruce E. and Jeng, Frank F.Johnson Space CenterSPACECRAFT DESIGN; SPACE SUITS; DESIGN ANALYSIS; ATMOSPHERIC PRESSURE; LIFE SUPPORT SYSTEMS; SYSTEMS ANALYSIS; SPACE EXPLORATION; PRODUCTIVITY; INTERNAL PRESSURE

Recapturing a Future for Space Exploration by National Research Council,Division on Engineering and Physical Sciences,Aeronautics and Space Engineering Board,Space Studies Board,Committee for the Decadal Survey on Biological and Physical Sciences in Space Pdf
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.

Systems Medicine For Human Spaceflight by Mark J Shelhamer,Erik Antonsen Pdf
This edited volume makes the case that a systems approach is needed for long-term spaceflight missions. Due to distance from Earth and the impossibility of resupply or rapid return, these flights will entail unprecedented autonomy on the part of the crew. This autonomy includes the need for local clinical decision support and other assistance with urgent medical concerns. The advantage of a systems approach to medical needs in human spaceflight is that it enables a systematic and repeatable methodology for identifying and developing the individual pieces of the spacecraft systems based on the human system needs that are unique to that problem and environment.The book begins by introducing a systems basis for thinking about humans in space. It describes existing models and paradigms of systems medicine, as well as the tools and analytical approaches involved. A tantalizing peek at preliminary applications of systems medicine in NASA is provided. As systems in human spaceflight continue to evolve for the foreseeable future, it is argued that a systems approach will help to ensure that the evolution of the relevant sub-systems is centered on optimal human-system function across the unique spaceflight needs of the developing customer base. The discussions on balancing the needs of the mission versus the maintenance of crew health, medical risk and liability for commercial spaceflights, and the need to anticipate what the next medical issues might be, will hopefully leave readers cautiously optimistic about this new frontier of applied science.

Exploration-Related Research on ISS by National Aeronautics and Space Administration (NASA) Pdf
In January, 2004, the U.S. President announced The Vision for Space Exploration, and charged the National Aeronautics and Space Administration (NASA) with using the International Space Station (ISS) for research and technology targeted at supporting U.S. space exploration goals. This paper describes: What we have learned from the first four years of research on ISS relative to the exploration mission; The on-going research being conducted in this regard; and Our current understanding of the major exploration mission risks that the ISS can be used to address. Specifically, we discuss research carried out on the ISS to determine the mechanisms by which human health is affected on long-duration missions, and to develop countermeasures to protect humans from the space environment. These bioastronautics experiments are key enablers of future long duration human exploration missions. We also discuss how targeted technological developments can enable mission design trade studies. We discuss the relationship between the ultimate number of human test subjects available on the ISS to the quality and quantity of scientific insight that can be used to reduce health risks to future explorers. We discuss the results of NASA's efforts over the past year to realign the ISS research programs to support a product-driven portfolio that is directed towards reducing the major risks of exploration missions. The fundamental challenge to science on ISS is completing experiments that answer key questions in time to shape design decisions for future exploration. In this context, exploration relevant research must do more than be conceptually connected to design decisions - it must become a part of the mission design process.Rhatigan, Jennifer L. and Robinson, Julie A. and Sawin, Charles F.Johnson Space CenterSPACE EXPLORATION; MISSION PLANNING; NASA PROGRAMS; INTERNATIONAL SPACE STATION; AEROSPACE ENVIRONMENTS; BIOASTRONAUTICS; HEALTH; RISK
