Today's final voyage for Endeavor marks the second-to-last government-funded launch as NASA completes the phasing out of its shuttle program. From now on, travel into the cosmos will be strictly for the ultra-rich. Virginia-based Space Adventures, Ltd. is the world's leading private space exploration company and the only company currently providing opportunities for actual private spaceflight and space tourism today. For the last ten years, the company has been brokering rides to the International Space Station through a partnership with Russia's space agency, which provides the Soyuz spacecraft for the flights. A trip for two in the luxury spaceship that will orbit the moon costs $150 million per person.
