Available in PDF, EPUB and Kindle. Book excerpt: "Beyond Einstein science" is a term that applies to a set of new scientific challenges at the intersection of physics and astrophysics. Observations of the cosmos now have the potential to extend our basic physical laws beyond where 20th-century research left them. Such observations can provide stringent new tests of Einstein's general theory of relativity, indicate how to extend the Standard Model of elementary-particle physics, and-if direct measurements of gravitational waves were to be made-give astrophysics an entirely new way of observing the universe. In 2003, NASA, working with the astronomy and astrophysics communities, prepared a research roadmap entitled Beyond Einstein: From the Big Bang to Black Holes. This roadmap proposed that NASA undertake space missions in five areas in order to study dark energy, black holes, gravitational radiation, and the inflation of the early universe, to test Einstein's theory of gravitation. This study assesses the five proposed Beyond Einstein mission areas to determine potential scientific impact and technical readiness. Each mission is explored in great detail to aid decisions by NASA regarding both the ordering of the remaining missions and the investment strategy for future technology development within the Beyond Einstein Program.

This book was released on 2006-06-30 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the space exploration initiative was announced, Congress asked the NRC to review the science NASA proposed to carryout under the initiative. It also asked the NRC to assess whether this program would provide balanced scientific research across the established disciplines supported by NASA in addition to supporting the new initiative. In 2005, the NRC released three studies focusing on a portion of that task, but changes at NASA forced the postponement of the last phase. This report presents that last phase with an assessment of the health of the NASA scientific disciplines under the budget requests imposed by the exploration initiative. The report also provides an analysis of whether the science budget appropriately reflects cross-disciplinary scientific priorities.

This book was released on 2009-05-21 with total page 764 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space-based laboratory research in fundamental physics is an emerging research discipline that offers great discovery potential and at the same time could drive the development of technological advances which are likely to be important to scientists and technologists in many other different research fields. The articles in this review volume have been contributed by participants of the international workshop “From Quantum to Cosmos: Fundamental Physics Research in Space” held at the Airlie Center in Warrenton, Virginia, USA, on May 21-24, 2006. This unique volume discusses the advances in our understanding of fundamental physics that are anticipated in the near future, and evaluates the discovery potential of a number of recently proposed space-based gravitational experiments. Specific research areas covered include various tests of general relativity and alternative theories, search of physics beyond the Standard Model, investigations of possible violations of the equivalence principle, search for new hypothetical long- and short-range forces, variations of fundamental constants, tests of Lorentz invariance and attempts at unification of the fundamental interactions. The book also encompasses experiments aimed at the discovery of novel phenomena, including dark matter candidates, and studies of dark energy.
Download or read book A Performance Assessment of NASA s Astrophysics Program written by National Research Council and published by National Academies Press. This book was released on 2007-06-21 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2006-04-05 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both the President's commission on how to implement the President's space exploration initiative and Congress asked the NRC undertake an assessment and review of the science proposed to be carried out under the initiative. An initial response to that request was the NRC February 2005 report, Science in NASA's Vision for Space Exploration. While that report's preparation, NASA created capabilities and strategy roadmapping efforts which became the object of the next phase of the NRC review. The new NASA administrator modified that NASA activity resulting in changes in the NRC review effort. This report provides a review of six science strategy roadmaps: robotic and human exploration of Mars; solar system exploration; universe exploration; search for earth-like planets; earth science and applications from space; and sun-earth system connection. In addition, an assessment of cross-cutting and integration issues is presented.

Download or read book Controlling Cost Growth of NASA Earth and Space Science Missions written by National Research Council and published by National Academies Press. This book was released on 2010-10-21 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cost and schedule growth is a problem experienced by many types of projects in many fields of endeavor. Based on prior studies of cost growth in NASA and Department of Defense projects, this book identifies specific causes of cost growth associated with NASA Earth and space science missions and provides guidance on how NASA can overcome these specific problems. The recommendations in this book focus on changes in NASA policies that would directly reduce or eliminate the cost growth of Earth and space science missions. Large cost growth is a concern for Earth and space science missions, and it can be a concern for other missions as well. If the cost growth is large enough, it can create liquidity problems for NASA's Science Mission Directorate that in turn cause cost profile changes and development delays that amplify the overall cost growth for other concurrent and/or pending missions. Addressing cost growth through the allocation of artificially high reserves is an inefficient use of resources because it unnecessarily diminishes the portfolio of planned flights. The most efficient use of resources is to establish realistic budgets and reserves and effective management processes that maximize the likelihood that mission costs will not exceed reserves. NASA is already taking action to reduce cost growth; additional steps, as recommended herein, will help improve NASA's mission planning process and achieve the goal of ensuring frequent mission opportunities for NASA Earth and space science.

This book was released on 2010-03-25 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: NASA's space and Earth science program is composed of two principal components: spaceflight projects and mission-enabling activities. Most of the budget of NASA's Science Mission Directorate (SMD) is applied to spaceflight missions, but NASA identifies nearly one quarter of the SMD budget as "mission enabling." The principal mission-enabling activities, which traditionally encompass much of NASA's research and analysis (R&A) programs, include support for basic research, theory, modeling, and data analysis; suborbital payloads and flights and complementary ground-based programs; advanced technology development; and advanced mission and instrumentation concept studies. While the R&A program is essential to the development and support of NASA's diverse set of space and Earth science missions, defining and articulating an appropriate scale for mission-enabling activities have posed a challenge throughout NASA's history. This volume identifies the appropriate roles for mission-enabling activities and metrics for assessing their effectiveness. Furthermore, the book evaluates how, from a strategic perspective, decisions should be made about balance between mission-related and mission-enabling elements of the overall program as well as balance between various elements within the mission-enabling component. Collectively, these efforts will help SMD to make a good program even better.
