The Falcon 1 was an expendable launch system privately developed and manufactured by SpaceX during 2006-2009. On 28 September 2008, Falcon 1 became the first privately-developed liquid-fuel launch vehicle to go into orbit around the Earth.
Falcon 9 is a two-stage rocket designed and manufactured by SpaceX for the reliable and safe transport of satellites and the Dragon spacecraft into orbit.
With the ability to lift into orbit over 54 metric tons (119,000 lb)--a mass equivalent to a 737 jetliner loaded with passengers, crew, luggage and fuel--Falcon Heavy can lift more than twice the payload of the next closest operational vehicle, the Delta IV Heavy, at one-third the cost.
Starship and Super Heavy Rocket represent a fully reusable transportation system designed to service all Earth orbit needs as well as the Moon and Mars. This two-stage vehicle — composed of the Super Heavy rocket (booster) and Starship (ship) — will eventually replace Falcon 9, Falcon Heavy and Dragon.
