"The rocket's first stage is composed of three Falcon 9 nine-engine cores whose 27 Merlin engines together generate more than 5 million pounds of thrust at liftoff, equal to about 18 747 aircraft. Only the Saturn V moon rocket, last flown in 1973, delivered more payload to orbit.

SpaceX founder Elon Musk has been aiming to build a rocket that will eventually carry people to Mars to form a colony. In September, the billionaire/business mogul said he plans to design a rocket that will take up to 100 people per launch to Mars, with the first flights happening as early as 2023.

"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," SpaceX said on its website."
