While this list is not exhaustive (e.g., Russian aircraft and spacecraft options are not included), it does include all practical vehicles for near-term space tourism whose use can be addressed by changes in present U.S. government policies. They have been organized into four categories: parabolic aircraft flights to simulate weightlessness, high-altitude aircraft rides to the edge of space, suborbital rides into space, and orbital trips.
