What is the best way to travel to space?
For the first half dozen decades of manned missions to space, the only way to participate was to earn a highly-competitive place in the national space programs of one of just a few countries that funded missions beyond the earth's atmosphere. Today, these national space programs are supplemented by a few private ventures that offer space tourism, typically for exorbitant fees.
