SpaceX is the abbreviated name for Space Exploration Technologies Corporation, an aerospace company that focuses on the manufacture of rockets and supply of the International Space Station with cargo. The company was founded by Elon Musk, the CEO of Tesla Motors.
In 2008, SpaceX developed the Falcon 1, the first privately funded liquid-propelled rocket to reach orbit. In 2010, the company launched the Dragon spacecraft used to transport cargo to the Internationsl Space Station, or ISS, in tandem with the Falcon 9 rocket. The Dragon was the first privately funded spacecraft to be put into orbit and recovered, and also the first private spacecraft to reach the ISS.
As of 2015, SpaceX has a contract with NASA to regularly bring supplies to the ISS and has made several successful deliveries. They also contract with the United States military and a number of private companies. In June of 2015 the company suffered the high-profile engine failure of one of its Falcon 9 rockets during launch.
SpaceX has a number of vehicles in development, including a reusable Falcon 9, a new rocket called the Falcon Heavy, a propulsive lander called the DragonFly, and an as-of-yet unnamed super-heavy lift launch vehicle. The company performed its first test flight of a passenger spaceship in May of 2015.
