This is a collection of six papers that were presented at COSPAR96, in Birmingham, U.K. This session showcased current and planned exploration activities for the giant planets, Jupiter and Saturn.

The Sun as a Guide to Stellar Physics illustrates the significance of the Sun in understanding stars through anexamination of the discoveries and insights gained from solar physics research. Ranging from theories to modelingand from numerical simulations to instrumentation and data processing, the book provides an overview of whatwe currently understand and how the Sun can be a model for gaining further knowledge about stellar physics.Providing both updates on recent developments in solar physics and applications to stellar physics, this bookstrengthens the solar–stellar connection and summarizes what we know about the Sun for the stellar, space, andgeophysics communities. - Applies observations, theoretical understanding, modeling capabilities and physical processes first revealed by the sun to the study of stellar physics - Illustrates how studies of Proxima Solaris have led to progress in space science, stellar physics and related fields - Uses characteristics of solar phenomena as a guide for understanding the physics of stars

In order to reflect the increasing importance and interest of the microsatellites in high technology and scientific applications in space, the Colloquium on Microsatellites as Research Tools was organized to promote its usage and technology development and to foster the international cooperation, especially in the area of the Asia pacific region.Attended by 150 participants from 18 countries the colloquium was organized into five major themes: regional development, lessons learned, innovations, scientific applications, and education. A special session was organized as well by the organizing committee and supported by the National Space Program Office to present its development of the Taiwan's satellite program and the current status of ROCSAT-1 which is scheduled to be launched at the beginning of 1999.Two main conclusions were drawn from the material presented: microsatellite in general is a very good means for doing space research and technology development, and a suitable vehicle to promote international collaborations.

Have you ever wondered what comets are and why astronomers spend so much time studying them? Now, a comet expert and an astronomical historian have come together to produce this unique book. Using their several decades of teaching experience, the authors have concisely presented the information you need to comprehend these majestic apparitions that grace our night skies. No mathematical proficiency is needed. In fact, this book doesn't contain a single equation. Comets are cosmic Rosetta stones, bridging our current knowledge by digging back to the earliest days of our solar systems. How did life arise on Earth? Did comets play a significant role in bringing water and the necessary organic matter to our early Earth? How about the dinosaurs? Were they driven to extinction by a cometary impact 66 million years ago? Comets may be both the enablers and destroyers of life on Earth as we know it. These are some of the tantalizing questions discussed here. If you so desire, steps are given to join the ranks of amateur comet hunters. Astronomy is one of the last sciences where amateurs play a significant role. Your reward for discovery? A comet officially bearing your name in the history books. The next great comet is on its way, we just do not know when it will arrive. Armed with this book, you will be ready to enjoy this unforgettable event.

This book provides an annual update on recent space launches, missions and results. The annual, written for both young and older space enthusiasts, provides a regular, balanced review of all the world’s major space programmes. It covers space exploration from a variety of angles: looking back at past missions, reviewing those currently under way and looking to those planned for the future. The ten invited contributions each year will cover a variety of topics within these areas. The book is for space enthusiasts from teens upwards through to professionals working in the worldwide space industry and journalists covering space issues.

A complete history of human endeavors in space, this book also moves beyond the traditional topics of human spaceflight, space technology, and space science to include political, social, cultural, and economic issues, and also commercial, civilian, and military applications. In two expertly written volumes, Space Exploration and Humanity: A Historical Encyclopedia covers all aspects of space flight in all participating nations, ranging from the Cold War–era beginnings of the space race to the lunar landings and the Apollo-Soyuz mission; from the Shuttle disasters and the Hubble telescope to Galileo, the Mars Rover, and the International Space Station. The book moves beyond the traditional topics of human spaceflight, space technology, and space science to include political, social, cultural, and economic issues, and also commercial, civilian, and military applications. Produced in conjunction with the History Committee of the American Astronautical Society, this work divides its coverage into six sections, each beginning with an overview essay, followed by an alphabetically organized series of entries on topics such as astrophysics and planetary science; civilian and commercial space applications; human spaceflight and microgravity science; space and society; and space technology and engineering. Whether investigating a specific issue or event or tracing an overarching historic trend, students and general readers will find this an invaluable resource for launching their study of one of humanity's most extraordinary endeavors.

As this excellent book demonstrates, the study of comets has now reached the fas cinating stage where we understand comets in general simple tenns while, at the same time, we are uncertain about practically all the details of cometary nature, structure, processes, and origin. In every aspect, even including dynamics, a choice among several or many competing theories is made impossible simply by the lack of detailed knowledge. The space missions, snapshot studies of two comets, partic ularly the one that immortalizes the name of Sir Edmund Halley, have produced a huge mass of valuable new infonnation and a number of surprises. Nonetheless, we face the tantalizing realization that we have obtained only a fleeting glance at two of perhaps a hundred billion (lOll) or more comets with possibly differing natures, origins, and physical histories. To my personal satisfaction, comets seem to have discrete nuclei made up of dirty snowballs, as I concluded four decades ago, but perhaps they are more like frozen rubbish piles.
