Falcon 1 was a small-lift launch vehicle that was operated from 2006 to 2009[5] by SpaceX, an American aerospace manufacturer. On 28 September 2008, Falcon 1 became the first privately-developed fully liquid-fueled launch vehicle to go into orbit around the Earth.[6][7]: 203

The two-stage-to-orbit rocket used LOX/RP-1 for both stages, the first powered by a single Merlin engine and the second powered by a single Kestrel engine. It was designed by SpaceX from the ground up.
The vehicle was launched a total of five times. After three failed launch attempts, Falcon 1 achieved orbit on its fourth attempt in September 2008 with a mass simulator as a payload. On 14 July 2009, Falcon 1 made its second successful flight, delivering the Malaysian RazakSAT satellite to orbit on SpaceX's first commercial launch (fifth and final launch overall). Following this flight, the Falcon 1 was retired and succeeded by Falcon 9.
SpaceX had announced an enhanced variant, the Falcon 1e,[4] but development was stopped in favor of Falcon 9.
