Book Description
The 2010 Astronomy and Astrophysics Decadal Survey report, New Worlds, New Horizons in Astronomy and Astrophysics (NWNH), outlines a scientifically exciting and programmatically integrated plan for both ground- and space-based astronomy and astrophysics in the 2012-2021 decade. However, late in the survey process, the budgetary outlook shifted downward considerably from the guidance that NASA had provided to the decadal survey. And since August 2010-when NWNH was released-the projections of funds available for new NASA Astrophysics initiatives has decreased even further because of the recently reported delay in the launch of the James Webb Space Telescope (JWST) to no earlier than the fourth quarter of 2015 and the associated additional costs of at least $1.4 billion. These developments jeopardize the implementation of the carefully designed program of activities proposed in NWNH. In response to these circumstances, NASA has proposed that the United States consider a commitment to the European Space Agency (ESA) Euclid mission at a level of approximately 20 percent. This participation would be undertaken in addition to initiating the planning for the survey's highest-ranked, space-based, large-scale mission, the Wide-Field Infrared Survey Telescope (WFIRST). The Office of Science and Technology Policy (OSTP) requested that the National Research Council (NRC) convene a panel to consider whether NASA's Euclid proposal is consistent with achieving the priorities, goals, and recommendations, and with pursuing the science strategy, articulated in NWNH. The panel also investigated what impact such participation might have on the prospects for the timely realization of the WFIRST mission and other activities recommended by NWNH in view of the projected budgetary situation. The panel convened a workshop on November 7, 2010. The workshop presentations identified several tradeoffs among options: funding goals less likely versus more likely to be achieved in a time of restricted budgets; narrower versus broader scientific goals; and U.S.-only versus U.S.-ESA collaboration. The panel captured these tradeoffs in considering four primary options: Option A: Launch of WFIRST in the Decade 2012-2021; Option B: A Joint WFIRST/Euclid Mission; Option C: Commitment by NASA of 20 percent Investment in Euclid prior to the M-class decision; or Option D: No U.S. Financing of an Infrared Survey Mission This Decade.

Book Description
Driven by discoveries, and enabled by leaps in technology and imagination, our understanding of the universe has changed dramatically during the course of the last few decades. The fields of astronomy and astrophysics are making new connections to physics, chemistry, biology, and computer science. Based on a broad and comprehensive survey of scientific opportunities, infrastructure, and organization in a national and international context, New Worlds, New Horizons in Astronomy and Astrophysics outlines a plan for ground- and space- based astronomy and astrophysics for the decade of the 2010's. Realizing these scientific opportunities is contingent upon maintaining and strengthening the foundations of the research enterprise including technological development, theory, computation and data handling, laboratory experiments, and human resources. New Worlds, New Horizons in Astronomy and Astrophysics proposes enhancing innovative but moderate-cost programs in space and on the ground that will enable the community to respond rapidly and flexibly to new scientific discoveries. The book recommends beginning construction on survey telescopes in space and on the ground to investigate the nature of dark energy, as well as the next generation of large ground-based giant optical telescopes and a new class of space-based gravitational observatory to observe the merging of distant black holes and precisely test theories of gravity. New Worlds, New Horizons in Astronomy and Astrophysics recommends a balanced and executable program that will support research surrounding the most profound questions about the cosmos. The discoveries ahead will facilitate the search for habitable planets, shed light on dark energy and dark matter, and aid our understanding of the history of the universe and how the earliest stars and galaxies formed. The book is a useful resource for agencies supporting the field of astronomy and astrophysics, the Congressional committees with jurisdiction over those agencies, the scientific community, and the public.

Book Description
New Worlds, New Horizons in Astronomy and Astrophysics (NWNH), the report of the 2010 decadal survey of astronomy and astrophysics, put forward a vision for a decade of transformative exploration at the frontiers of astrophysics. This vision included mapping the first stars and galaxies as they emerge from the collapse of dark matter and cold clumps of hydrogen, finding new worlds in a startlingly diverse population of extrasolar planets, and exploiting the vastness and extreme conditions of the universe to reveal new information about the fundamental laws of nature. NWNH outlined a compelling program for understanding the cosmic order and for opening new fields of inquiry through the discovery areas of gravitational waves, time-domain astronomy, and habitable planets. Many of these discoveries are likely to be enabled by cyber-discovery and the power of mathematics, physics, and imagination. To help realize this vision, NWNH recommended a suite of innovative and powerful facilities, along with balanced, strong support for the scientific community engaged in theory, data analysis, technology development, and measurements with existing and new instrumentation. Already in the first half of the decade, scientists and teams of scientists working with these cutting-edge instruments and with new capabilities in data collection and analysis have made spectacular discoveries that advance the NWNH vision. New Worlds, New Horizons: A Midterm Assessment reviews the responses of NASA's Astrophysics program, NSF's Astronomy program, and DOE's Cosmic Frontiers program to NWNH. This report describes the most significant scientific discoveries, technical advances, and relevant programmatic changes in astronomy and astrophysics over the years since the publication of the decadal survey, and assesses how well the Agencies' programs address the strategies, goals, and priorities outlined in the 2010 decadal survey.

Book Description
NASA's exploration of planets and satellites during the past 50 years has led to the discovery of traces of water ice throughout the solar system and prospects for large liquid water reservoirs beneath the frozen ICE shells of multiple satellites of the giant planets of the outer solar system. During the coming decades, NASA and other space agencies will send flybys, orbiters, subsurface probes, and, possibly, landers to these distant worlds in order to explore their geologic and chemical context. Because of their potential to harbor alien life, NASA will select missions that target the most habitable outer solar system objects. This strategy poses formidable challenges for mission planners who must balance the opportunity for exploration with the risk of contamination by Earth's microbes, which could confuse the interpretation of data obtained from these objects. The 2000 NRC report Preventing the Forward Contamination of Europa provided a criterion that was adopted with prior recommendations from the Committee on Space Research of the International Council for Science. This current NRC report revisits and extends the findings and recommendations of the 2000 Europa report in light of recent advances in planetary and life sciences and, among other tasks, assesses the risk of contamination of icy bodies in the solar system.

Book Description
The National Research Council (NRC) has been conducting decadal surveys in the Earth and space sciences since 1964, and released the latest five surveys in the past 5 years, four of which were only completed in the past 3 years. Lessons Learned in Decadal Planning in Space Science is the summary of a workshop held in response to unforseen challenges that arose in the implementation of the recommendations of the decadal surveys. This report takes a closer look at the decadal survey process and how to improve this essential tool for strategic planning in the Earth and space sciences. Workshop moderators, panelists, and participants lifted up the hood on the decadal survey process and scrutinized every element of the decadal surveys to determine what lessons can be gleaned from recent experiences and applied to the design and execution of future decadal surveys.

Book Description
The National Research Council has conducted 11 decadal surveys in the Earth and space sciences since 1964 and released the latest four surveys in the past 8 years. The decadal surveys are notable in their ability to sample thoroughly the research interest, aspirations, and needs of a scientific community. Through a rigorous process, a primary survey committee and thematic panels of community members construct a prioritized program of science goals and objectives and define an executable strategy for achieving them. These reports play a critical role in defining the nation's agenda in that science area for the following 10 years, and often beyond. The Space Science Decadal Surveys considers the lessons learned from previous surveys and presents options for possible changes and improvements to the process, including the statement of task, advanced preparation, organization, and execution. This report discusses valuable aspects of decadal surveys that could taken further, as well as some challenges future surveys are likely to face in searching for the richest areas of scientific endeavor, seeking community consensus of where to go next, and planning how to get there. The Space Science Decadal Surveys describes aspects in the decadal survey prioritization process, including balance in the science program and across the discipline; balance between the needs of current researchers and the development of the future workforce; and balance in mission scale - smaller, competed programs versus large strategic missions.

Book Description
On November 8-10, 2010, the National Research Council's Space Studies Board (SSB) held a public workshop on how NASA and its associated science and exploration communities communicate with the public about major NASA activities and programs. The concept and planning of the workshop developed over a period of two years. In conjunction with the SSB, the workshop planning committee identified five "Grand Questions" in space science and exploration around which the event was organized. As outlined in the summary, the workshop concluded with sessions on communicating space research and exploration to the public.

Book Description
Through an examination of case studies, agency briefings, and existing reports, and drawing on personal knowledge and direct experience, the Committee on Assessment of Impediments to Interagency Cooperation on Space and Earth Science Missions found that candidate projects for multiagency collaboration in the development and implementation of Earth-observing or space science missions are often intrinsically complex and, therefore costly, and that a multiagency approach to developing these missions typically results in additional complexity and cost. Advocates of collaboration have sometimes underestimated the difficulties and associated costs and risks of dividing responsibility and accountability between two or more partners; they also discount the possibility that collaboration will increase the risk in meeting performance objectives. This committee's principal recommendation is that agencies should conduct Earth and space science projects independently unless: It is judged that cooperation will result in significant added scientific value to the project over what could be achieved by a single agency alone; or Unique capabilities reside within one agency that are necessary for the mission success of a project managed by another agency; or The project is intended to transfer from research to operations necessitating a change in responsibility from one agency to another during the project; or There are other compelling reasons to pursue collaboration, for example, a desire to build capacity at one of the cooperating agencies. Even when the total project cost may increase, parties may still find collaboration attractive if their share of a mission is more affordable than funding it alone. In these cases, alternatives to interdependent reliance on another government agency should be considered. For example, agencies may find that buying services from another agency or pursuing interagency coordination of spaceflight data collection is preferable to fully interdependent cooperation.
