Falcon Heavy is a heavy-lift launch vehicle with partial reusability that can carry cargo into Earth orbit, and beyond. It is designed, manufactured and launched by American aerospace company SpaceX.
The rocket consists of a center core on which two Falcon 9 boosters are attached, and a second stage on top of the center core.[8] Falcon Heavy has the second highest payload capacity of any currently operational launch vehicle behind NASA's Space Launch System (SLS), and the fourth-highest capacity of any rocket to reach orbit, trailing behind the SLS, Energia and the Saturn V.
SpaceX conducted Falcon Heavy's maiden launch on 6 February 2018, at 20:45 UTC.[4] As a dummy payload, the rocket carried a Tesla Roadster belonging to SpaceX founder Elon Musk, with a mannequin dubbed "Starman" in the driver's seat.[9] The second Falcon Heavy launch occurred on 11 April 2019, and all three booster rockets successfully returned to Earth.[10] The third Falcon Heavy launch successfully occurred on 25 June 2019. Since then, Falcon Heavy has been certified for the National Security Space Launch (NSSL) program.[11]
Falcon Heavy was designed to be able to carry humans into space beyond low Earth orbit, although as of February 2018[update], SpaceX does not intend to transport people on Falcon Heavy, nor pursue the human-rating certification process to transport NASA astronauts.[12] Both Falcon Heavy and Falcon 9 are expected to eventually be superseded by the Starship super-heavy lift launch vehicle, currently being developed.[13]
