Space Exploration Technologies Corporation (SpaceX) is an American aerospace manufacturer and space transport services company with its headquarters in Hawthorne, California, USA. It was founded in 2002 by former PayPal entrepreneur and Tesla Motors CEO Elon Musk with the goal of creating the technologies to reduce space transportation costs and enable the colonization of Mars. It has developed the Falcon 1 and Falcon 9 launch vehicles, both of which were designed from conception to eventually become reusable, and the Dragon spacecraft which is flown into orbit by the Falcon 9 launch vehicle to supply the International Space Station (ISS) with cargo.
Falcon – 9 : SpaceX has successfully landed an unmanned rocket upright, after sending 11 satellites into orbit. Now this return-to-flight mission has made history — no one else has ever landed a rocket that has gone as deep into space as the Falcon 9. This has happened in Dec -2015.
