Falcon Heavy is a partially reusable super heavy-lift launch vehicle designed and manufactured by SpaceX. It is derived from the Falcon 9 vehicle and consists of a strengthened Falcon 9 first stage as a central core with two additional first stages as strap-on boosters. 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 2018. SpaceX conducted Falcon Heavy's maiden 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. Falcon Heavy was designed to carry humans into space beyond low Earth orbit, especially to the Moon, Mars, and potentially to asteroids for mining, although as of February 2018, Musk does not plan to apply for a human-rating certification to carry NASA astronauts. At an appearance in May 2004 before the United States Senate Committee on Commerce, Science, and Transportation, Musk testified, " Long term plans call for development of a heavy lift product and even a super-heavy, if there is customer demand. We expect that each size increase would result in a meaningful decrease in cost per pound to orbit. ... Ultimately, I believe $500 per pound or less is very achievable." This $1,100 per kilogram ($500/lb) goal stated by Musk in 2011 is 35% of the cost of the lowest-cost-per-pound LEO-capable launch system in a circa-2000 study: the Zenit, a medium-lift launch vehicle that can carry 14,000 kilograms (30,000 lb) into LEO. As of March 2013, Falcon Heavy launch prices are below $2,200/kg ($1,000/lb) to low-Earth orbit when the launch vehicle is transporting its maximum delivered cargo weight. Launch contracts typically reflect launch prices at the time the contract is signed. In 2011, SpaceX stated that the cost of reaching low Earth orbit could be as low as $2,200/kg ($1,000/lb) if an annual rate of four launches can be sustained, and as of 2011 planned to eventually launch as many as 10 Falcon Heavies and 10 Falcon 9s annually. A third launch site, intended exclusively for SpaceX private use, is planned at Boca Chica Village, Texas. SpaceX started construction on the third Falcon Heavy launch facility in 2014, with the first launches from the facility no earlier than late 2018. In late 2013, SpaceX had projected Falcon Heavy's inaugural flight to be in 2014, but it did not occur until February 2018 due to limited manufacturing capacity and the need to deliver on the Falcon 9 launch manifest. By late 2013, SpaceX prices for space launch were already the lowest in the industry. SpaceX's price for reused spacecraft could be reduced up to 30% short term, and potentially even further in the future.
