Falcon 9 is a family of rocket-powered spaceflight launch vehicles designed and manufactured by SpaceX, headquartered in Hawthorne, California. The family consists of the Falcon 9 v1. 0, Falcon 9 v1. 1, and the Falcon 9-R. Both stages of this two-stage-to-orbit vehicle burn liquid oxygen and rocket-grade kerosene propellants. The current Falcon 9 can lift payloads of 13,150 kilograms to low Earth orbit, and 4,850 kilograms to geostationary transfer orbit. All three Falcon 9 vehicles are situated in the medium-lift range of launch systems. The Falcon 9 and Dragon capsule combination won a Commercial Resupply Services contract from NASA to resupply the International Space Station under the Commercial Orbital Transportation Services program. The first commercial resupplymission to the International Space Station launched on October 7, 2012. Falcon 9 will also be human-rated for transporting astronauts under NASA's CCDev program. SpaceX has developed a new and 60percent larger launch vehicle—the Falcon 9 v1. 1—which flew for the first time on a demonstration mission on the sixth overall launch of the Falcon 9 on September 29, 2013. The Falcon 9 will be the base for the Falcon Heavy launch vehicle.
