Space Exploration Technologies (SpaceX) is developing a family of launch vehicles intended to reduce the cost and increase the reliability of both manned and unmanned space transportation ultimately by a factor of ten. With its Falcon line of launch vehicles, SpaceX is able to offer light (with the Falcon 1), medium and heavy lift capabilities (with the Falcon 9) to deliver spacecraft into any inclination and altitude, from low Earth orbit to geosynchronous orbit to planetary missions.
