Book Description
While NASA Earth Science missions are planned on the basis of a specified lifetime, often they are able to function beyond the end of that period. Until recently NASA had no formal mechanism for determining whether those missions should be extended or whether the resources necessary for the extension should be applied to new missions. In August 2004, when NASA merged Earth and space sciences, the agency began using the Science Review process to make those extension determinations. NASA had asked the NRC to assess extension review processes, and after the merger, this study focused on the Science Review process. This report presents an assessment of that process and provides recommendations for adapting it to Earth Science missions.

Book Description
Because of the Moon's unique place in the evolution of rocky worlds, it is a prime focus of NASA's space exploration vision. Currently NASA is defining and implementing a series of robotic orbital and landed missions to the Moon as the initial phase of this vision. To realize the benefits of this activity, NASA needs a comprehensive, well-validated, and prioritized set of scientific research objectives. To help establish those objectives, NASA asked the NRC to provide guidance on the scientific challenges and opportunities enabled by sustained robotic and human exploration of the Moon during the period 2008-2023 and beyond. This final report presents a review of the current understanding of the early earth and moon; the identification of key science concepts and goals for moon exploration; an assessment of implementation options; and a set of prioritized lunar science concepts, goals, and recommendations. An interim report was released in September 2006.

Book Description
The astronomy science centers established by the National Aeronautics and Space Administration (NASA) to serve as the interfaces between astronomy missions and the community of scientists who utilize the data have been enormously successful in enabling space-based astronomy missions to achieve their scientific potential. These centers have transformed the conduct of much of astronomical research, established a new paradigm for the use of large astronomical facilities, and advanced the science far beyond what would have been possible without them. Portals to the Universe: The NASA Astronomy Science Centers explains in detail the findings of this report.

Book Description
The Vision for Space Exploration (VSE) announced by President George W. Bush in 2004 sets NASA and the nation on a bold path to return to the Moon and one day put a human on Mars. The long-term endeavor represented by the VSE is, however, subject to the constraints imposed by annual funding. Given that the VSE may take tens of years to implement, a significant issue is whether NASA and the United States will have the workforce needed to achieve that vision. The issues range from short-term concerns about the current workforce's skills for overseeing the development of new spacecraft and launch vehicles for the VSE to long-term issues regarding the training, recruiting, and retaining of scientists and engineers in-house as well as in industry and academia. Asked to explore science and technology (S&T) workforce needs to achieve the nation's long-term space exploration, the Committee on Meeting the Workforce Needs for the National Vision for Space Exploration concluded that in the short term, NASA does not possess the requisite in-house personnel with the experience in human spaceflight systems development needed to implement the VSE. But the committee acknowledges that NASA is cognizant of this fact and has taken steps to correct it, primarily by seeking to recruit highly skilled personnel from outside NASA, including persons from industry and retirees. For the long term, NASA has to ask if it is attracting and developing the talent it will need to execute a mission to return to the Moon, and the agency must identify what it needs to do to attract and develop a world-class workforce to explore other worlds. A major challenge for NASA is reorienting its human spaceflight workforce from the operation of current vehicles to the development of new vehicles at least throughout the next decade, as well as starting operations with new rockets and new spacecraft. The committee emphasizes further that when evaluating its future workforce requirements, NASA has to consider not only programs for students, but also training opportunities for its current employees. NASA's training programs at the agency's various field centers, which are focused on NASA's civil service talent, require support to prevent the agency's internal skill base from withering. Furthermore, NASA faces the risk that, if it fails to nurture its own internal workforce, skilled personnel will be attracted to other government agencies and industry. Building a Better NASA Workforce: Meeting the Workforce Needs for the National Vision for Space Exploration explains the findings and recommendations of the committee.

Book Description
Understanding the effects of natural and human-induced changes on the global environment and their implications requires a foundation of integrated observations of land, sea, air and space, on which to build credible information products, forecast models, and other tools for making informed decisions. The 2007 National Research Council report on decadal survey called for a renewal of the national commitment to a program of Earth observations in which attention to securing practical benefits for humankind plays an equal role with the quest to acquire new knowledge about the Earth system. NASA responded favorably and aggressively to this survey, embracing its overall recommendations for Earth observations, missions, technology investments, and priorities for the underlying science. As a result, the science and applications communities have made significant progress over the past 5 years. However, the Committee on Assessment of NASA's Earth Science Program found that the survey vision is being realized at a far slower pace than was recommended, principally because the required budget was not achieved. Exacerbating the budget shortfalls, NASA Earth science programs experienced launch failures and delays and the cost of implementing missions increased substantially as a result of changes in mission scope, increases in launch vehicle costs and/or the lack of availability of a medium-class launch vehicle, under-estimation of costs by the decadal survey, and unfunded programmatic changes that were required by Congress and the Office of Management and Budget. In addition, the National Oceanic and Atmospheric Administration (NOAA) has made significant reductions in scope to its future Earth environmental observing satellites as it contends with budget shortfalls. Earth Science and Applications from Space: A Midterm Assessment of NASA's Implementation of the Decadal Survey recommends a number of steps to better manage existing programs and to implement future programs that will be recommended by the next decadal survey. The report also highlights the urgent need for the Executive Branch to develop and implement an overarching multiagency national strategy for Earth observations from space, a key recommendation of the 2007 decadal survey that remains unfulfilled.

Book Description
NASA operates a large number of space science missions, approximately three-quarters of which are currently in their extended operations phase. They represent not only a majority of operational space science missions, but a substantial national investment and vital national assets. They are tremendously scientifically productive, making many of the major discoveries that are reported in the media and that rewrite textbooks. Extending Science â€" NASA's Space Science Mission Extensions and the Senior Review Process evaluates the scientific benefits of missions extensions, the current process for extending missions, the current biennial requirement for senior reviews of mission extensions, the balance between starting new missions and extending operating missions, and potential innovative cost-reduction proposals for extended missions, and makes recommendations based on this review.

Book Description
Astrobiology is a scientific discipline devoted to the study of life in the universe - its origin, evolution, distribution, and future. In 1997, NASA established an Astrobiology program (the NASA Astrobiology Institute - NAI) as a result of a series of new results from solar system exploration and astronomical research in the mid-1990s together with advances in the biological sciences. To help evaluate the NAI, NASA asked the NRC to review progress made by the Institute in developing the field of astrobiology. This book presents an evaluation of NAI's success in meeting its goals for fostering interdisciplinary research, training future astrobiology researchers, providing scientific and technical leadership, exploring new research approaches with information technology, and supporting outreach to K-12 education programs.

Book Description
While a number of remarkable discoveries in astronomy and astrophysics have taken place over the past 20 years, many important questions remain. Continued progress in these fields will require NASA's leadership. To help determine if NASA can meet this challenge, Congress, in the 2005 NASA Authorization Act, directed the agency to have "[t]he performance of each division in the Science directorate...reviewed and assessed by the National Academy of Sciences at 5-year intervals." In early 2006, NASA asked the NRC to conduct such an assessment for the agency's Astrophysics Division. This report presents an assessment of how well NASA's current program addresses the strategies, goals, and priorities outlined in previous Academy reports. The report provides an analysis of progress toward realizing these strategies, goals, and priorities; and a discussion of actions that could be taken to optimize the scientific value of the program in the context of current and forecasted resources.
