This combination of text and reference book describes the physical, plasma and chemical processes controlling the behavior of ionospheres, upper atmospheres and exospheres. It summarizes the structure, chemistry, dynamics and energetics of the terrestrial ionosphere and other solar system bodies, and discusses the processes, mechanisms and transport equations for solving fundamental research problems. This second edition incorporates new results, model developments and interpretations from the last 10 years. It includes the latest material on neutral atmospheres; the terrestrial ionosphere at low, middle and high latitudes; and planetary atmospheres and ionospheres, where results from recent space missions have yielded fresh data. Appendices outline physical constants, mathematical formulas, transport coefficients, and other important parameters for ionospheric calculations. This is an essential resource for researchers studying ionospheres, upper atmospheres, aeronomy and plasma physics.

Spacecraft formation flying (SFF) is of huge importance to the aerospace and space community. Not the stuff of science-fiction, SFF involves flying multiple small satellites together, to deliver benefits which far outweigh a single larger craft or space station. The first autonomous formation flying earth science mission was in 196 and NASA now has 35 SFF mission sets. By networking several smaller and cheaper craft, scientists can make simultaneous measurements that enable higher resolution astronomical imagery, provide robust and fault-tolerant spacecraft system architectures, and enable complex earth science and space science networks dispersed over clusters of satellites in space. This is the first book to introduce and explore SFF. It is a topic of enormous importance to aerospace engineers, astrodynamicists, satellite engineers, astronomers, physicists, and applied mathematicions. This book provides a complete introduction to the subject and is supported by graduate level student exercises plus Matlab and Maple code sets for running SFF simulations. The first book dedicated to spacecraft formation flying which is the enabling element of distributed spacecraft systems Written by the leading researchers and teachers in the field; perfect for research and graduate students Accompanied by Matlab and Maple code sets and exercises for graduate level students of aerospace science, astrodynamics and orbital mechanics

From a space shuttle fashioned out of a lemonade carton and felt to a Mars rover made from a cereal box and juice cans, the variety of imaginative projects in this resource can be built with simple everyday classroom and household items. Surrounding these activities are fun facts, illustrations, and related information on each space topic—all of which meets curriculum standards for early elementary science. For young students, their families, and teachers, this expedition through the galaxy is a perfect method for introducing astronomy in a way that also stimulates creativity and curiosity.

Energy, chemistry, solvents, and habitats - the basic elements of living systems - define the opportunities and limitations for life on other worlds. This class-tested text examines each of these parameters in crucial depth and makes the argument that life forms we would recognize may be more common in our solar system than many assume. It also considers, however, exotic forms of life that would not have to rely on carbon as basic chemical element, solar energy as a main energy source, or water as primary solvent. Finally the question of detecting bio- and geosignature of such life forms is discussed, ranging from Earth environments to deep space. While speculative considerations in this emerging field of science cannot be avoided, the authors have tried to present their study with the breadth and seriousness that a scientific approach to this issue requires. They seek an operational definition of life and investigate the realm of possibilities that nature offers to realize this very special state of matter and avoid scientific jargon wherever possible to make this intrinsically interdisciplinary subject understandable to a broad range of readers. The second edition thoroughly updates this text in view of the rapid progress in the field and a substantial amount of new material has been added, in particular sections and chapters on adaptation to extreme environments, the future and fate of living systems, life detection concepts based on the thorough analysis of the Viking missions and the issue around the meteorite ALH 84001, and - last but not least - recommendations for the optimization of future space exploration missions.

In six years, Galileo Galilei went from being a mathematics professor to a star in the court of Florence to a target of the Inquisition. And during that time, Galileo made a series of astronomical discoveries that reshaped the ideas of the physical nature of the heavens and transformed him from a university mathematician into a court philosopher. Galileo's Instruments of Credit proposes radical new interpretations of key episodes of Galileo's career, including his telescopic discoveries of 1610, the dispute over sunspots, and the conflict with the Holy Office over the relationship between Copernicanism and Scripture. Galileo's tactics shifted as rapidly as his circumstances, argues Mario Biagioli, and these changes forced him to respond swiftly to the opportunities and risks posed by unforeseen inventions, other discoveries, and his opponents. Focusing on the aspects of Galileo's scientific life that extended beyond court culture and patronage, Biagioli offers a revisionist account of the different systems of exchanges, communication, and credibility at work in Galileo's career. Galileo's Instruments of Credit will fascinate readers interested in the history of astronomy and the history of science in general.

There are many planetary systems other than our own, but it is only through a detailed understanding of the relatively accessible bodies in our solar system that a thorough appreciation of planetary science can be gained. This is particularly pertinent with the recent discovery of extra-solar planets and the desire to understand their formation and the prospect of life on other worlds.

The field of space and astronomy is devoted to the study of the heavenly bodies, their behavior, and characteristics. As the oldest natural science, knowledge of astronomy has come from some of the world's greatest scientists, including Copernicus, Galileo, Kepler, Newton, and Einstein. Astronomy experiments are not only historically important, but they also provide knowledge of basic scientific principles, such as how early thinkers disproved the notion that Earth is the center of the solar system. Modern astronomy relies on technology that has been invented in the last few decades, and current research includes space travel, satellites, and telescopes that interpret radiation from all parts of the electromagnetic spectrum. "Space and Astronomy Experiments" provides teachers with 20 new and original experiments that help students learn basic scientific principles and important skills. Presenting experiments from all areas, including physics and geology, the text contains proven classroom experiments that broaden understanding of both science facts and the nature of space and astronomy. Full-color line illustrations, tables, and charts round out this comprehensive resource.

This book describes the phenomena of cyclic activity as they are observed in the Sun and solar-type stars. Although there are many books currently available on the Sun, solar activity, and activity phenomena in stars, this is the only one that links these topics and attempts to define stellar parameters that are conducive to activity in general and cyclic activity in particular and to descibe the mechanisms responsible for the various modes of activity. The first seven chapters review our basic knowledge of the Sun, of the solar activity cycle, and of stellar activity cycles. Chapter 1 also describes some of the terrestrial effects of solar activity and stresses the importance of reliable predictions of the parameters of future cycles. Chapters 8 through 13 describe some of the latest research into the solar cycle, including extended activity cycle and the polar fields reversal. The latest contributions from studies of dynamo theory, of helioseismology, and of chaos theory are also covered. The last chapter discusses the methods currently in use to predict parameters of future cycles and their success (or failure) for the maximum of cycle 22.
