Elon Musk is the chief designer for SpaceX, overseeing development of rockets and spacecraft for missions to Earth orbit and ultimately to other planets. In 2008, SpaceX’s Falcon 9 rocket and Dragon spacecraft won the NASA contract to provide a commercial replacement for the cargo transport function of the space shuttle. In 2012, SpaceX became the first commercial company to dock with the International Space Station and return cargo to Earth with the Dragon.
At Tesla, Musk has overseen product development and design from the beginning, including the all-electric Tesla Roadster, Model S and Model X, and overseeing the rollout of Supercharger stations to keep the cars juiced up. (Some of the charging stations use solar energy systems from SolarCity, of which Musk is the non-executive chair.) Transitioning to a sustainable energy economy, in which electric vehicles play a pivotal role, has been one of his central interests for almost two decades. He co-founded PayPal and served as the company's chair and CEO.
