Traveling into space and visiting or even emigrating to nearby worlds will soon become part of the human experience. Scientists, engineers, and investors are working hard to make space tourism a reality. As experienced astronauts will tell you, extraterrestrial travel is incomparably thrilling. To make the most of the experience requires profound physical and mental adjustments by travelers as they adapt to microgravity and alterations in virtually every aspect of life, from eating to intimacy. Everyone who goes into space and returns sees Earth and life on it from a profoundly different perspective. If you have ever wondered about space travel, now you have the opportunity to find out. Astronomer and former NASA/ASEE scientist Neil F. Comins has written the go-to book for anyone interested in space exploration, including potential travelers.

He describes the joys and the dangers travelers will face--weightlessness, unparalleled views of Earth and the cosmos, the opportunity to walk on or jump off another world, as well as radiation, projectiles, unbreathable atmospheres, and potential equipment failures. He also provides insights into specific types of travel and destinations, including suborbital flights (nonstop flights to space and back), Earth-orbiting space stations, the Moon, asteroids, comets, and Mars--the first-choice candidate for colonization. Although many challenges to space travel are technical, Comins outlines these matters in clear language for all readers. He synthesizes key issues and cutting-edge research in astronomy, physics, biology, psychology, and sociology to create a complete manual for those eager to take the ultimate voyage, as well as those just interested in the adventure.
