Falcon Heavy is a reusable heavy-lift launch vehicle designed and made by SpaceX. It is inspired from the Falcon 9 vehicle. This increases the low Earth orbit (LEO) maximum payload to 63,800 kilograms (140,700 pounds), compared to 22,800 kilograms (50,300 pounds) for a Falcon 9 Full Thrust, 28,790 kilograms (63,470 pounds) for Delta IV Heavy, 27,500 kilograms (60,600 pounds) for the Space Shuttle and 140,000 kilograms (310,000 pounds) for Saturn V. Falcon Heavy is the world's fourth-highest capacity rocket ever built, after Saturn V, Energia and N1, and the most powerful rocket in operation as of 2020. SpaceX conducted Falcon Heavy's first launch on February 6, 2018, at 3:45 p.m. EST (20:45 UTC). The rocket carried a Tesla Roadster belonging to SpaceX founder Elon Musk as a dummy payload into a path around the sun. The first commercial launch was on 11 April 2019, for Arabsat. It was a success.
