Space: final frontier or ultimate tourist destination? Possibly both—provided you have the cash. Already, you can buy tickets for (as-yet-unscheduled) flights aboard SpaceShipTwo, the crew vehicle developed by Richard Branson’s Virgin Galactic. And at a NewSpace conference in Seattle last month, Blue Origin—helmed by Amazon founder Jeff Bezos—announced that it has plans to sell tickets to wannabe space tourists as early as next year.
