To travel to the edge of space you can strap yourself into a capsule and ride atop of a carefully controlled explosion or you can enter a crew capsule and be gently lifted by a balloon into the stratosphere. Unlike a suborbital rocket flight lasting for a few minutes a ride under a balloon can give you several hours to enjoy the wonders of the Earth and its curvature against the back drop of space. Tucson based World View Enterprises is on track to take you on such a balloon ride to the edge of space for the price of a $75,000 ticket. This innovative company is getting started with an unmanned balloon borne capsule called the Stratollite.
