The Ansari X Prize garnered teams from countries as varied as Russia, Canada, Romania, Israel, England, Argentina and the United States. Contrary to the expectation that big aerospace companies would jump to get involved, many of the teams' companies were founded after the announcement of the contest, and teams often consisted of their founders. When Scaled Composites' SpaceShipOne took the prize, more than 20 teams were registered. Most only managed to complete the design or build the spacecraft, but a few did have test flights with demonstrator rockets -- some successful, others not so successful. Here's a breakdown of the successful ones:
