Product Description
The availability of energy resources is expected to become an increasing concern in the next fifty years, as it is the key to industrial development, transportation and commerce. An alternative yet potential solution for energy problems lies in the utilization of space. For example, sunlight reflectors of several hectares in area could contribute to future power engineering or for illuminating designated regions of the planet with sunlight.
This book describes a feasible means of constructing such a reflector, as well as simple, reliable and low-cost structures for television and radio transmissions, debris removal from space and the development of solar sails for interplanetary missions. The aim of this book is thus to provide a comprehensive overview of the research in the technology of such space based structures expanded by centrifugal forces.
The most promising concepts and design solutions for different applications are addressed. Particular emphasis is placed on deployment dynamics of s ... Read more

Product Description
Humans have long thought that planetary systems similar to our own should exist around stars other than the Sun, yet the search for planets outside our Solar System has had a dismal history of discoveries that could not be confirmed. However, this all changed in 1995, after which astonishing progress can be seen in this field; we now know of more than 200 extrasolar planets. These findings mark crucial milestones in the search for extraterrestrial life - arguably one of the most intriguing endeavors of modern science. These proceedings from the 2005 Space Telescope Science Institute Symposium on Extrasolar Planets explore one of the hottest topics in astronomy. Discussions include the Kepler mission, observational constraints on dust disk lifetimes and the implications for planet formation, and gravitational instabilities in protoplanetary disks. With review papers written by world experts in their fields, this is an important resource on extrasolar planets. ... Read more
