Book Description
In response to the mandate contained in the National Aeronautics and Space Administration (NASA) Authorization Act of 2010, Pub. L. No. 111-267, Section 503(c)(2), for GAO to provide an evaluation of the accuracy and level of confidence in the findings contained in NASA's assessment of the essential modules, operational systems and components, structural elements, and permanent scientific equipment required to ensure complete, effective, and safe functioning and full scientific utilization of the International Space Station through 2020. Our objectives were to determine (1) how NASA will ensure that the ISS is structurally sound and that essential spares and replacement components are available to support safe functioning and full scientific utilization through 2020, and (2) the extent to which NASA's assessment of the essential spares necessary to assure continued operations of the ISS through 2020 is supported by sufficient, accurate, and relevant underlying data and appropriate and reasonable methodologies. NASA is using analytical techniques, physical tests, and inspections to assess primary structures and functional systems and determine sparing needed to support safe functioning and full scientific utilization of the ISS through 2020. These assessments are ongoing, so all results are not yet available. Our work indicates that NASA's assessments appear to be supported by sufficient, accurate and relevant underlying data. We found, however, that NASA's estimates of ISS sparing needs are sensitive to assumptions about hardware reliability.

Book Description
This CSIS Report examines the strategic implications of manned space exploration. The current phase of exploration is coming to an end, and nations are seeking the next step. The decisions of the United States and its partners on the future of space exploration will determine the strategic situation in space. There are difficult issues to consider in moving ahead: the target of exploration beyond LEO, the balance between manned and unmanned programs, the future of partnership and cooperation in space, and the ultimate fate of the ISS. How Western space powers answer these questions will determine both the pace and the future direction of exploration in space.

Book Description
The Hubble Space Telescope (HST) has operated continuously since 1990. During that time, four space shuttle-based service missions were launched, three of which added major observational capabilities. A fifth â€" SM-4 â€" was intended to replace key telescope systems and install two new instruments. The loss of the space shuttle Columbia, however, resulted in a decision by NASA not to pursue the SM-4 mission leading to a likely end of Hubble's useful life in 2007-2008. This situation resulted in an unprecedented outcry from scientists and the public. As a result, NASA began to explore and develop a robotic servicing mission; and Congress directed NASA to request a study from the National Research Council (NRC) of the robotic and shuttle servicing options for extending the life of Hubble. This report presents an assessment of those two options. It provides an examination of the contributions made by Hubble and those likely as the result of a servicing mission, and a comparative analysis of the potential risk of the two options for servicing Hubble. The study concludes that the Shuttle option would be the most effective one for prolonging Hubble's productive life.

Book Description
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.
