Musk was long convinced that for life to survive, humanity has to become a multiplanet species. However, he was dissatisfied with the great expense of rocket launchers. In 2002 he founded Space Exploration Technologies (SpaceX) to make more affordable rockets. Its first two rockets were the Falcon 1 (first launched in 2006) and the larger Falcon 9 (first launched in 2010), which were designed to cost much less than competing rockets.
