High-Tech Tourism

Until recently the only people who could visit the most extreme environments, such as the ocean floor or outer space, were highly trained, often government-funded specialists like scientists, astronauts, and fighter pilots. But all that is changing. Today, or in the not-too-distant future, private individuals with the moxie and the money can or will soon be able to travel just about anywhere on or above Earth. In this slide show, get a taste of the possibilities.—Gaia Remerowski
