Hypothetical Spacecraft and Interstellar Travel collects information about the latest and greatest hypothetical spacecraft.

Interstellar Travel: Purpose and Motivations is a comprehensive, technical look at the necessary considerations for interstellar travel addressed by leading experts in the field, from scientists studying possible destinations (exoplanets) and the vast distances between, to those concerned with building institutions and capabilities in society that could sustain such endeavors. In addition to the technical, medical, and anthropological aspects of deep space travel, the ethics and morality of spreading Earth-based life to other worlds is also examined. In the first book of a three-book compilation, Interstellar Travel: Purpose and Motivations offers in-depth, up-to-date and realistic technical and scientific considerations in the pursuit of interstellar travel and is an integral reference for scientists, engineers, researchers and academics working on, or interested in, space development and space technologies. With a renewed interest in space exploration and development evidenced by the rise of the commercial space sector and various governments now planning to send humans back to the moon and to Mars, so also is interest in taking the next steps beyond the Solar System and to the ultimate destination – planets circling other stars. Features detailed overviews with quantification of the technical challenges and potential benefits of interstellar missions Comprehensively covers the considerations for interstellar travel by the world's recognized leading experts in the field Features referenceable data and analysis for both new and experienced researchers in the interstellar and exoplanets fields

Sci-fi novels, movies, and TV shows have provided ideas on how interstellar space travel might be accomplished, allowing humans to travel far beyond the Milky Way galaxy. Many of these ideas are being explored by scientists today. In this enlightening book, readers learn about how human interstellar travel might be accomplished and how STEM skills are being used to solve the problems involved. Human interstellar space travel raises a variety of ethical questions as well, such as who goes on this one-way trip, traveling far from home for years or even generations? This resource provides a human and technical overview of a captivating, yet contentious, topic.

Louis Friedman, Executive Director of the Planetary Society, presents the first comprehensive look at the science and history behind solar sailing and other designs for space travel. Serious science readers and space buffs alike will be fascinated by designs for the square sail, disk sail, and the heliogyro (which features flexible sails many kilometers long). Friedman compares solar sailing to other proposed propulsion sytems such as ion drives and laser propulsion, and takes an insider's look at the million-dollar JPL project of the late '70s, which was the first attempt at a working model. Illustrated.

Some theoreticians contemplate and formulate the physics of tachyons, which are hypothetical particles, that would always travel faster than light but which could never slow down to the speed of light just as they anticipate sublight speed massive particles never being able to achieve light speed. So my theoretical work on the physics and kinematics of light-speed massive systems sets me apart from general trends in the theoretical field of relativistic astronautics. This book is a continuation of how and why we may be able to, at some future time, travel at the speed of light.

A detailed introduction is presented to the problems of interstellar space travel. The general topics discussed include: basics of travel in space, advanced propulsion methods; relativity and interstellar travel; relativistic drives and problems; starships as systems; missions; astrogation, observation, and communication; technological requirements and hazards; biological requirements; personal, social, and political considerations; interstellar life and civilizations; long-term prospects.
