PDF-(DOWNLOAD)-Interstellar Travel: An Astronomer\'s guide (Space Travel)

This book describes the many astronomical and humanscale issues that make interstellar travel a formidable challenge even with the right technology for making the actual trip Since the 1920s science fiction authors have invented dozens of ways to make interstellar travel a reality Sadly after nearly 100 years of effort scientists and engineers have yet to invent a single inexpensive technology to get us to the stars What is more disturbing about this challenge is that the actual technology to make the trip is mostly irrelevant Some of the issues are already known and being addressed such as What will be our destination How many travelers should go What will happen to human health along the way But the Big Picture of interstellar travel goes well beyond the design of the engines that power our starships Once we arrive at our destination what will we do Will our immune systems be so compromised from the travel that we can never actually visit the surface of a biologicallyactive planet What will we breath Will we be forced to live under a dome and never venture outside without a spacesuit What kind of a reward will that be for a decades or centurieslong voyage What will communication with Earth be like with time delays of 100 years These and many other questions will be covered as astronomer Sten Odenwald explores the other issues and challenges of interstellar travel that arise from living in an unfortunately very limited physical world He will also explore optimistic scenarios involving artificial intelligence and hibernation that could completely change the game in making interstellar travel a reality.

The Starflight Handbook A Pioneer\'s Guide to Interstellar TravelThe Starflight Handbook is an indispensable compendium of the manyand varied methods for traversing the vast interstellar gulf--don\'tleave the Solar System without it! --Robert Forward Verysensible, very complete and useful. Its good use of references andtechnical \'sidebars\' adds to the book and allows the nontechnicaltext to be used by ordinary readers in an easy fashion. I certainlywould recommend this book to anyone doing any thinking at all aboutinterstellar flight or the notion of possibilities of contactsbetween hypothetical civilizations in different stat systems.--Louis Friedman Executive Director, The Planetary Society TheStarflight Handbook is the first and only compendium on planetEarth of the radical new technologies now on the drawing boards ofsome of our smartest and most imaginative space scientists andengineers. Scientists and engineers as well as general readers willbe captivated by its: * In-depth discussions of everything from nuclear pulse propulsionengines to in-flight navigation, in flowing, non-technicallanguage * Sidebars and appendices cover technical and mathematical conceptsin detail * Seventy-five elegant and enlightening illustrations depictingstarships and their hardware \"
The touchstone for contemporary stargazers.
This classic, groundbreaking guide has been the go-to field guide for both beginning and experienced amateur astronomers for nearly 30 years. The fourth edition brings Terence Dickinson and Alan Dyer\'s invaluable manual completely up-to-date. Setting a new standard for astronomy guides, it will serve as the touchstone for the next generation of stargazers as well as longtime devotees.Technology and astronomical understanding are evolving at a breathtaking clip, and to reflect the latest information about observing techniques and equipment, this massively revised and expanded edition has been completely rebuilt (an additional 48 pages brings the page count to 416). Illustrated throughout with all-new photographs and star charts, this edition boasts a refreshed design and features five brand-new chapters, including three essential essays on binocular, telescope and Moon tours by renowned astronomy writer Ken Hewitt-White.With new content on naked-eye sky sights, LED lighting technology, WiFi-enabled telescopes and the latest advances in binoculars, telescopes and other astronomical gear, the fourth edition of The Backyard Astronomer\'s Guide is sure to become an indispensable reference for all levels of stargazers. New techniques for observing the Sun, the Moon and solar and lunar eclipses are an especially timely addition, given the upcoming solar eclipses in 2023 and 2024. Rounding out these impressive offerings are new sections on dark sky reserves, astro-tourism, modern astrophotography and cellphone astrophotography, making this book an enduring must-have guide for anyone looking to improve his or her astronomical viewing experience.The Backyard Astronomer\'s Guide also features a foreword by Dr. Sara Seager, a Canadian-American astrophysicist and planetary scientist at the Massachusetts Institute of Technology and an internationally recognized expert in the search for exoplanets.\" Observing the Sun is for amateur astronomers at all three levels: beginning, intermediate, and advanced.The beginning observer is often trying to find a niche or define a specific interest in his hobby, and the content of this book will spark that interest in solar observing because of the focus on the dynamics of the Sun.Intermediate and advanced observers will find the book invaluable in identifying features (through photos, charts, diagrams) in a logical, orderly fashion and then guiding the observer to interpret the observations.Because the Sun is a dynamic celestial body in constant flux, astronomers rarely know for certain what awaits them at the eyepiece. All features of the Sun are transient and sometimes rather fleeting. Given the number of features and the complex life cycles of some, it can be a challenging hobby. Observing the Sun provides essential illustrations, charts, and diagrams that depict the forms and life cycles of the numerous features visible on the Sun. If you’ve ever been interested in the night sky and the wonders above our heads, search no further: your ultimate resource for all things in the universe is here. From David Dickinson and Fraser Cain, publisher of the widely popular astronomy news site, Universe Today, comes the complete guide of the night sky, ranging from the best tips and tricks for viewing, an overview of the solar system and our galaxy to exclusive interviews with top NASA scientists, interwoven with exclusive, beautiful photography from top night sky photographers.Foreword is expected to be written by a top industry professional (hopefully Dr. Pamela Gay or Bill Nye). With calendars, charts and graphs, you’ll treasure this definitive resource for many night sky viewings from now and for years to come. When is travel . considered. University . Business. ? .
