SpaceX is an American aerospace manufacturer and launch services provider founded by Elon Musk in 2002 with the goal of making life multiplanetary. It developed the reusable Falcon 9, now by far the most flown orbital rocket in the world, the Dragon capsule that carries NASA astronauts to the International Space Station, and Starship, the fully reusable super-heavy vehicle intended for lunar and Mars missions. The company also operates Starlink, a satellite constellation of thousands of spacecraft providing broadband to consumers, aircraft, ships and militaries, which has become its largest source of revenue.

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.
