Solar sail technology is very close to becoming an engineering reality and it will soon be used in the exploration of the solar system and beyond. This fascinating book provides an accessible introduction to solar sails and details how they work and what they will be used for in the exploration of space. It also examines current plans for solar sails and how advanced technology, such as nanotechnology, might enhance their performance. Coverage shows how solar sail propulsion will make space exploration more affordable and demonstrates how access to destinations within (and beyond) the solar system will become within reach.

What was our planet like before the advent of our modern civilization? What effects has our civilization had on the planet and its ecological systems? Paradise Regained discusses these questions and then creates a scenario for the re-greening of Earth. The authors introduce new and innovative ideas on how humankind might use the resources of the solar system for terrestrial benefit. Earth would then become a place for a technologically advanced human civilization to live in synchronization, if not in harmony, with the environment which gave us birth. Since the formation of our solar system, the resources and ecological state of Earth have undergone many changes. The environmental challenges facing humanity today, as the authors posit them, will not be resolved simply by conservation and Earth-based alternative technologies. Paradise Regained considers the environmental dilemma and highlights the risk of humankind's future extinction from environmental degradation. Human population growth, climate change, and the strained sustainability of the few remaining habitats for wild life are all discussed. The authors, however, are not discouraged and offer a potential solution through the development of space. Not only will extraterrestrial resources help avert environmental disaster, but will also provide the basis for continued technological and societal progress. The resources of the solar system will help meet our projected industrial needs and feed our industry once terrestrial sources are depleted. Space-based power generation systems will work synergistically with Earth-based conservation. Paradise Regained concludes with the discussion on how closed ecological systems in space will help us to build a prosperous and sustainable future for all humanity.

A Traveler’s Guide to the Stars

Review\n"What will it take to explore a distant star within 100 years? To illuminate the momentousness (and ethics) of sending humans light-years from home, NASA scientist Les Johnson helps us digest mind-boggling numbers―the distance between stars, the energy required to travel that far―while laying out the opportunities and limits of existing technologies. Whether we get there by solar sails or ion thrusters or nuclear bombs, the advances we make in pursuit of interstellar travel will likely also change the way we live on Earth."---Fionna M. D. Samuels, Scientific American\nA brief guide to the real science of interstellar travel\nWith known exoplanets now numbering in the thousands and initiatives like 100 Year Starship and Breakthrough Starshot advancing the idea of interstellar travel, the age-old dream of venturing forth into the cosmos and perhaps even colonizing distant worlds may one day become a reality. A Traveler’s Guide to the Stars reveals how.\nLes Johnson takes you on a thrilling tour of the physics and technologies that may enable us to reach the stars. He discusses the latest exoplanet discoveries, promising interstellar missions on the not-so-distant horizon, and exciting new developments in space propulsion, power, robotics, communications, and more. But interstellar travel will not be easy, and it is not for the faint of heart. Johnson describes the harsh and forbidding expanse of space that awaits us, and he addresses the daunting challenges―both human and technological―that we will need to overcome in order to realize tomorrow’s possibilities.\nA Traveler’s Guide to the Stars is your passport to the next great frontier of human discovery, providing a rare inside look at the remarkable breakthroughs in science and technology that will help tomorrow’s space travelers chart a course for the stars.
