This volume considers the role comets may have played in the origins and evolution of life. This is the only book dealing in depth with this subject. It is particularly relevant in light of recent investigations of Halley's comet, of new insights into organic synthesis in meteorites and comets, and of new results of numerical simulations of cometary orbits and impacts on Earth. The book is intended as a comprehensive review of current research.

Hermann Oberth gilt als einer der bedeutendsten Pioniere der Raketentechnik. Visionar waren nicht nur seine umfassende, akribische Untersuchung und Optimierung aller denkbaren Raketenparamter, sondern auch seine Vorschlage zur Raketeninstrumentierung fur bemannte und wissenschaftliche Missionen sowie Ideen fur Start- und Testanlagen. Die Neuauflage ermoglicht es, die Realisierung von Oberth's "Traum" nachzuvollziehen und mit der heutigen Raumfahrtrealitat abzugleichen. Reprint der 5. Auflage von 1984

This is quite simply the first volume of its kind dedicated to the area of high time resolution astrophysics. High time resolution astrophysics (HTRA) is an important new window on the universe and a vital tool in understanding a range of phenomena from diverse objects and radiative processes. Underlining this science foundation, technological developments in both instrumentation and detectors are described.

Written by two of the best US researchers in the field, this text investigates issues of astrobiological relevance in the context of cold aqueous planetary geochemistry. At the core of the technical chapters is the FREZCHEM model, initially developed over many years by one of the authors to quantify aqueous electrolyte properties and chemical thermodynamics at subzero temperatures. FREZCHEM is of huge relevance to scientists in a number of fields, including biogeochemists.

This fascinating book reviews the progress made in Mercury studies since the flybys by Mariner 10 in 1974-75. Thus far, it is the only book on Mercury which balances a wide range of Earth-based observations, made under difficult conditions, with the only available space-based data. The text is based on continued research using the Mariner 10 archive, on observations from Earth, and on increasingly realistic models of this mysterious planet's interior evolution.
