An Integrated Strategy for the Planetary Sciences: 1995-2010

199477570Washington DC: National Research Council 1994. Presumed First Edition First printing. Trade paperback. Good. xi 1 199 1 pages. Tables. Figures. References. Bibliography of Space Studies Board Planetary Sciences Reports. Cover has wear and soiling. An Integrated Strategy for the Planetary Sciences: 1995-2010 explains that a responsive planetary exploration program demands a mix of mission sizes ranging from comprehensive missions with multiple objectives such as Galileo and Cassini to small missions with highly constrained scientific objectives. 2 At the same time The Role of Small Missions in Planetary and Lunar Exploration concluded that a series of small missions present "the planetary science community with the opportunity to expand the scope of its activities and to develop the potential and inventiveness of its members in ways not possible within the confines of large traditional programs." In 1992 the National Research Council's Space Studies Board charged its Committee on Planetary and Lunar Exploration to: 1 summarize current understanding of the planets and the solar system; 2 pose significant scientific questions; and 3 establish priorities for scientific exploration of the planets for the period from 1995 to 2010. The scientific goals of solar system exploration include: 1 understanding how physical and chemical processes determine the major characteristics of the planets; 2 learning how planetary systems evolve; 3 determining how life developed particularly on Earth and in what ways life modifies planetary environments; and 4 discovering how simple basic laws of physics and chemistry can lead to the diverse phenomena observed in complex systems. COMPLEX maintains that the most useful programs to emphasize in the period from 1995 to 2010 are investigations of comets Mars and Jupiter and an intensive search for and characterization of extrasolar planets.

Health Effects to Exposure to Low Levels of Ionizing Radiation; BEIR V.

199074457Washington DC: National Research Council 1990. Presumed First paperback Edition First printing. Trade paperback. Good. xiii 1 421 1 pages. Illustrations. References. Glossary. Index. Ex-library with usual markings. Some markings blacked out. Cover has some wear and soiling and front corner creased. The Committee was asked to conduct a comprehensive review of the biological effects of ionizing radiation focusing on information that had been reported since the conclusion of the BEIR III study and to the extent that available information permitted provide new estimates of the risks of genetic and somatic effects in humans due to low-level exposures of ionizing radiation. These risk estimates were to address both internal and external sources of radiation and the procedures by which these risk estimates were derived was to be documented. The Committee on the Biological Effects of Ionizing Radiation BEIR is a committee of the American National Research Council. It publishes reports on the effects of ionizing radiation. This book reevaluates the health risks of ionizing radiation in light of data that have become available since the 1980 report on this subject was published. The data include new much more reliable dose estimates for the A-bomb survivors the results of an additional 14 years of follow-up of the survivors for cancer mortality recent results of follow-up studies of persons irradiated for medical purposes and results of relevant experiments with laboratory animals and cultured cells. It analyzes the data in terms of risk estimates for specific organs in relation to dose and time after exposure and compares radiation effects between Japanese and Western populations.

The Decade of Discovery in Astronomy and Astrophysics

199181246Washington DC: National Academy Press 1991. Presumed First Edition First printing. Trade paperback. Very good. xvi 2 181 1 pages. Tables. Figures some in color. References. Appendices. Index. Slight cover wear. The Committee on Astronomy and Astrophysics CAA provides an independent authoritative forum for identifying and discussing issues in astronomy and astrophysics with the research community the federal government and the interested public. The committee supports scientific progress in astronomy and astrophysics by providing advice to the federal government on the implementation of decadal survey recommendations. The CAA will issue reports that will provide guidance to federal agencies that support astronomy and astrophysics research. The CAA's scope spans the full range of astronomy and astrophysics research including space- and ground-based observations. The Committee's domain encompasses stellar galactic and extragalactic astronomy particle astrophysics cosmology the search for extra-solar planets and aspects of fundamental physics relating to astronomical objects. The CAA's scope also includes appropriate cross-disciplinary areas and consideration of budget and programmatic aspects of the implementation of the decadal survey. Astronomers and astrophysicists are making revolutionary advances in our understanding of planets stars galaxies and even the structure of the universe itself. The Decade of Discovery presents a survey of this exciting field of science and offers a prioritized agenda for space- and ground-based research into the twenty-first century. The book presents specific recommendations programs and expenditure levels to meet the needs of the astronomy and astrophysics communities. Accessible to the interested lay reader the book explores: The technological investments needed for instruments that will be built in the next century. The importance of the computer revolution to all aspects of astronomical research. The potential usefulness of the moon as an observatory site. Policy issues relevant to the funding of astronomy and the execution of astronomical projects. The Decade of Discovery will prove valuable to science policymakers research administrators scientists and students in the physical sciences and interested lay readers.
