Available in PDF, EPUB and Kindle. Book excerpt: In recent decades, several lines of scientific investigation have converged to bring into sharp focus our understanding of the solar system. Intensive observations by spacecraft and other means, combined with extraordinary laboratory analytical methods and theoretical investigations, are beginning to paint an intelligible picture of our solar system's history, the mechanisms of its development, and the relationship between the formation of our Sun and its associated planets. Astronomical observations are providing important new information about the processes that give birth to stars and about the conditions in star-forming regions and around very young stars that might be conducive to establishing planetary systems. This progress leads naturally to a new line of inquiry: the discovery and characterization of planetary systems around other stars. This report describes a general plan and the pertinent technological requirements for TOPS (Toward Other Planetary Systems), a staged program to ascertain the prevalence and character of other planetary systems and to construct a definitive picture of the formation of stars and their planets. The first stages focus on discovering and studying a significant number of fully formed planetary systems, as well as expanding current studies of protoplanetary systems. As the TOPS Program evolves, emphasis will shift toward intensive study of the discovered systems and of individual planets. Early stages of the TOPS Program can be undertaken with ground-based observations and space missions comparable in scale to those now being performed. In the long term, however, TOPS will become an ambitious program that challenges our capabilities and provides impetus for major space initiatives and new technologies, which will be accomplishments of historical significance.

Download or read book Planetary Systems Formation Evolution and Detection written by Bernard F. Burke and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: `Are there other planetary systems like ours? Other planets like ours? Is there life elsewhere in the Universe?' So asks Dr. Lew Allen Jr. in the Foreword. In December of 1992, theorists, observers, and instrument builders gathered at the California Institute of Technology to discuss the search for answers to these questions. The International Conference, entitled `Planetary Systems: Formation, Evolution, and Detection' and supported through NASA's newly formed TOPS (Toward Other Planetary Systems) program, was the first of a series of conferences uniting researchers across disciplines and political boundaries to share thoughts and information on planetary systems. The conference was sponsored by NASA, hosted by JPL at Caltech, and endorsed by the 1992 International Space Year Association. These proceedings include discussions of topics ranging from stellar, disk, and planetary formation to new ways of searching for other stellar systems containing planets. The authors represent a wide range of nationalities, disciplines, and points of view. The second international conference took place in December of 1993.

Available in PDF, EPUB and Kindle. Book excerpt: During 1988, the National Research Council's Space Science Board reorganized itself to more effectively address NASA's advisory needs. The Board's scope was broadened: it was renamed the Space Studies Board and, among other new initiatives, the Committee on Human Exploration was created. The new committee was intended to focus on the scientific aspects of human exploration programs, rather than engineering issues. Their research led to three reports: Scientific Prerequisites for the Human Exploration of Space published in 1993, Scientific Opportunities in the Human Exploration of Space published in 1994, and Science Management in the Human Exploration of Space published in 1997. These three reports are collected and reprinted in this volume in their entirety as originally published.
Download or read book Space and the American Imagination written by Howard E. McCurdy and published by JHU Press. This book was released on 2011-03 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: People dreamed of cosmic exploration—winged spaceships and lunar voyages; space stations and robot astronauts—long before it actually happened. Space and the American Imagination traces the emergence of space travel in the popular mind, its expression in science fiction, and its influence on national space programs. Space exploration dramatically illustrates the power of imagination. Howard E. McCurdy shows how that power inspired people to attempt what they once deemed impossible. In a mere half-century since the launch of the first Earth-orbiting satellite in 1957, humans achieved much of what they had once only read about in the fiction of Jules Verne and H. G. Wells and the nonfiction of Willy Ley. Reaching these goals, however, required broad-based support, and McCurdy examines how advocates employed familiar metaphors to excite interest (promising, for example, that space exploration would recreate the American frontier experience) and prepare the public for daring missions into space. When unexpected realities and harsh obstacles threatened their progress, the space community intensified efforts to make their wildest dreams come true. This lively and important work remains relevant given contemporary questions about future plans at NASA. Fully revised and updated since its original publication in 1997, Space and the American Imagination includes a reworked introduction and conclusion and new chapters on robotics and space commerce.

This book was released on 2012-12-06 with total page 721 pages. Available in PDF, EPUB and Kindle. Book excerpt: ROSAT Observations G. HASINGER Max-Planck-Institut flir extraterrestrische Physik, D-85740 Garching, Germany Abstract. This review describes the most recent advances in the study of the extragalactic soft X-ray background and what we can learn about its constituents. The deepest pointed observations with the ROSAT PSPC are discussed. The logN-logS relation is presented, which reaches to the faintest X-ray fluxes and to the highest AGN surface densities ever achieved. The N(>S) relation shows a 2 density in excess of 400 deg- at the faintest fluxes and a flattening below the Einstein Deep Survey limit. About 60% of the extragalactic background has been resolved in the deepest field. Detailed source spectra and first optical and radio identifications will be discussed. The results are put into perspective of the higher energy X -ray background. Key words: X-rays, background radiations, active galactic nuclei. 1. Introduction The extragalactic X-ray background (XRB), discovered about 30 years ago, has been studied extensively with many X-ray experiments, in particular with the satel lites HEAO I and II (see ego Boldt 1987) and with ROSAT (e. g. Hasinger et aI. , 1993). Figure 1 shows a compilation of some of the most recent spectral measure ments for the X-ray background. Over the energy range from 3 to about 100 keY its spectrum can be well approximated by an optically thin thermal bremsstrahlung model with kT ~ 40 keY, while at lower X-ray energies a steepening into a new component has been observed observed (e. g.

Download or read book Advances in Spacecraft Attitude Control written by Timothy Sands and published by BoD – Books on Demand. This book was released on 2020-01-15 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spacecraft attitude maneuvers comply with Euler's moment equations, a set of three nonlinear, coupled differential equations. Nonlinearities complicate the mathematical treatment of the seemingly simple action of rotating, and these complications lead to a robust lineage of research. This book is meant for basic scientifically inclined readers, and commences with a chapter on the basics of spaceflight and leverages this remediation to reveal very advanced topics to new spaceflight enthusiasts. The topics learned from reading this text will prepare students and faculties to investigate interesting spaceflight problems in an era where cube satellites have made such investigations attainable by even small universities. It is the fondest hope of the editor and authors that readers enjoy this book.
