Founded by Elon Musk in 2002, Space Exploration Technologies Corporation (SpaceX) is a space transport services company whose mission is to reduce space transportation costs and enable the colonization of Mars. It has developed several launch vehicles and spacecraft.

In 2006, NASA awarded SpaceX a contract to design a launch system to resupply cargo to the International Space Station (ISS); by 2014, SpaceX had flown four missions to the ISS. NASA also awarded SpaceX a contract to develop a human-rated spacecraft as part of its program to transport crew to the ISS. SpaceX is planning its first crewed flight in 2015.

SpaceX’s achievements include the first privately funded, liquid-fueled rock to reach orbit; the first privately funded company to launch, orbit and recover a spacecraft; the first private company to send a spacecraft to the ISS; and the first private company to send a satellite into geosynchronous orbit.
