Bezos owns Blue Origin, which is currently developing a reusable rocket that could take passengers on commercial suborbital space flights from as early as next year. "My business model right now for Blue Origin is I sell about a billion a year of Amazon stock and I use it to fund Blue Origin," Bezos said at the Space Symposium conference in Colorado on Wednesday. "So the business model for Blue Origin is very robust."

Last week, the spaceflight company released the first interior photos of its New Shepard capsule, revealing a spacious cabin with enormous windows. As passengers will be asked to hand over as much as $300,000 for a ticket to space, Bezos and co. believe comfortable recliners -- at least in comparison to SpaceX's Crew Dragon capsule -- and expansive views will make the cost worthwhile.

Bezos isn't alone in his dream, though. Both Elon Musk's SpaceX and Richard Branson's Virgin Galactic are working on reusable crafts that will reduce the cost of taking people into space. At the same conference, SpaceX President Gwynne Shotwell revealed that the company spent "substantially less than half" the cost of a new first stage for the Falcon 9 re-flight and that costs are only likely to fall as future spaceflights will require less maintenance between launches.
