The most powerful rocket by lift capacity currently in service is the Falcon Heavy, made by American commercial rocket builders SpaceX. It is around twice as capable in lifting a payload as any other operational heavy-lift rocket, being able to carry payloads of as much as 63,800 kg (140,660 lb) into low Earth orbit. Its three booster cores and 27 engines create 22,819 kiloNewtons (5.13 million pounds-force) of thrust at lift-off at sea level, and 24,681 kN (5,548,500 lbf) in the vacuum of space. Its maiden flight took place on 6 February 2018, with lift-off at 3:45 p.m. (EST: 8:45 p.m. UTC) from Cape Canaveral Air Force Station in Florida, USA.The rocket is 70 m (229 ft 6 in) tall and weighs 1,420,788 kg (3,125,735 lb). In absolute terms it is second only to the US Saturn V (retired 1973) by payload. For its maiden flight it carried an unorthodox test payload: SpaceX founder Elon Musk's personal Tesla Roadster electric car, which was launched into heliocentric orbit with a cargo that comprised a mannequin in a space suit, a copy of the Hitchhikers Guide to the Galaxy and a towel.
