Book Description
The Spitzer Space Observatory, originally known as the Space Infrared Telescope Facility (SIRTF), is the last of the four “Great Observatories”, which also include the Hubble Space Telescope, the Chandra X-ray Observatory, and the Compton Gamma Ray Observatory. Developed over twenty years and dubbed the “Infrared Hubble", Spitzer was launched in the summer of 2003 and has since contributed significantly to our understanding of the universe. George Rieke played a key role in Spitzer and now relates the story of how that observatory was built and launched into space. Telling the story of this single mission within the context of NASA space science over two turbulent decades, he describes how, after a tortuous political trail to approval, Spitzer was started at the peak of NASA’s experiment with streamlining and downsizing its mission development process, termed “faster better cheaper.” Up to its official start and even afterward, Spitzer was significant not merely in terms of its scientific value but because it stood at the center of major changes in space science policy and politics. Through interviews with many of the project participants, Rieke reconstructs the political and managerial process by which space missions are conceived, approved, and developed. He reveals that by the time Spitzer had been completed, a number of mission failures had undermined faith in “faster-better-cheaper” and a more conservative approach was imposed. Rieke examines in detail the premises behind “faster better cheaper,” their strengths and weaknesses, and their ultimate impact within the context of NASA’s continuing search for the best way to build future missions. Rieke’s participant’s perspective takes readers inside Congress and NASA to trace the progress of missions prior to the excitement of the launch, revealing the enormously complex and often disheartening political process that needs to be negotiated. He also shares some of the new observations and discoveries made by Spitzer in just its first year of operation. As the only book devoted to the Spitzer mission, The Last of the Great Observatories is a story at the nexus of politics and science, shedding new light on both spheres as it contemplates the future of mankind’s exploration of the universe.

Book Description
This book introduces the reader to the field of nuclear astrophysics, i.e. the acquisition and reading of measurements on unstable isotopes in different parts of the universe. The authors explain the role of radioactivities in astrophysics, discuss specific sources of cosmic isotopes and in which special regions they can be observed. More specifically, the authors address stars of different types, stellar explosions which terminate stellar evolutions, and other explosions triggered by mass transfers and instabilities in binary stars. They also address nuclear reactions and transport processes in interstellar space, in the contexts of cosmic rays and of chemical evolution. A special chapter is dedicated to the solar system which even provides material samples. The book also contains a description of key tools which astrophysicists employ in those particular studies and a glossary of key terms in astronomy with radioactivities.

Book Description
This book summarizes the science to be carried out by the upcoming Cherenkov Telescope Array, a major ground-based gamma-ray observatory that will be constructed over the next six to eight years. The major scientific themes, as well as core program of key science projects, have been developed by the CTA Consortium, a collaboration of scientists from many institutions worldwide.CTA will be the major facility in high-energy and very high-energy photon astronomy over the next decade and beyond. CTA will have capabilities well beyond past and present observatories. Thus, CTA's science program is expected to be rich and broad and will complement other major multiwavelength and multimessenger facilities. This book is intended to be the primary resource for the science case for CTA and it thus will be of great interest to the broader physics and astronomy communities. The electronic version (e-book) is available in open access.

Book Description
The COSPAR Colloquium on Solar-Terrestrial Magnetic Activity and Space Environment (STMASE) was held in the National Astronomy Observatories of Chinese Academy of Sciences (NAOC) in Beijing, China in September 10-12, 2001. The meeting was focused on five areas of the solar-terrestrial magnetic activity and space environment studies, including study on solar surface magnetism; solar magnetic activity, dynamical response of the heliosphere; space weather prediction; and space environment exploration and monitoring. A hot topic of space research, CMEs, which are widely believed to be the most important phenomenon of the space environment, is discussed in many papers. Other papers show results of observational and theoretical studies toward better understanding of the complicated image of the magnetic coupling between the Sun and the Earth, although little is still known little its physical background. Space weather prediction, which is very important for a modern society expanding into out-space, is another hot topic of space research. However, a long way is still to go to predict exactly when and where a disaster will happen in the space. In that sense, there is much to do for space environment exploration and monitoring. The manuscripts submitted to this Monograph are divided into the following parts: (1) solar surface magnetism, (2) solar magnetic activity, (3) dynamical response of the heliosphere, (4) space environment exploration and monitoring; and (5) space weather prediction. Papers presented in this meeting but not submitted to this Monograph are listed by title as unpublished papers at the end of this book.
