Falcon Heavy is a reusable super heavy-lift launch vehicle designed and manufactured by SpaceX. The Falcon Heavy (which was earlier described as the Falcon 9 Heavy) is a variant of the Falcon 9 vehicle and consists of a strengthened Falcon 9 rocket core with two additional Falcon 9 first stages as strap-on boosters. This increases the low Earth orbit (LEO) maximum payload to 63,800 kilograms (140,700 lb), compared to 22,800 kg (50,300 lb) for a Falcon 9 Full Thrust, 27,500 kg (60,600 lb) for the now-retired NASA Space Shuttle and 140,000 kg (310,000 lb) for the Saturn V. The Falcon Heavy is the world's 4th highest capacity rocket ever to be built, after Saturn V, Energia and N1, and the highest capacity rocket in current operation as of February 6, 2018, superseding the Delta IV Heavy payload by more than double. Falcon Heavy was designed from the outset to carry humans into space, including the Moon and Mars, although as of February 5, 2018, there are no plans to use Falcon Heavy for crewed missions; it will instead be devoted to payloads such as large satellites.
SpaceX successfully launched the Falcon Heavy on February 6, 2018. The dummy payload on its maiden flight was SpaceX founder Elon Musk's Tesla Roadster
