Falcon Heavy is a reusable super heavy-lift launch vehicle being designed and manufactured by SpaceX. The Falcon Heavy (previously known as the Falcon 9 Heavy) is a variant of the Falcon 9 launch vehicle and will consist of a strengthened Falcon 9 rocket core with two additional Falcon 9 first stages as strap-on boosters.This will increase the low Earth orbit (LEO) maximum payload to 63.8 metric tonnes, compared to 22.8 tonnes for a Falcon 9 full thrust. Falcon Heavy was designed from the outset to carry humans into space and would enable crewed missions to the Moon or Mars.

The  Falcon Heavy in fully expendable mode can handle any previously flown mission, including all interplanetary and moon manned missions.
When Falcon Heavy lifts off , it will be the most powerful operational rocket in the world. With the ability to lift into orbit over 54 metric tons. It’s first stage is composed of three Falcon 9  – engine cores whose 27 Merlin engines together generate more than 5 million pounds of thrust at lift off, equal to approximately eighteen 747 aircraft. Falcon heavy was designed from the outset to carry humans into space and restores the possibility of flying missions with crew to the moon or mars.
