SpaceX's Falcon Heavy rocket is a heavy-lift booster that will be the largest, most powerful privately built rocket in history. See how SpaceX's Falcon Heavy rocket will work in this Space.com infographic. (Image credit: By Karl Tate, Infographics Artist) To gain a fuller understanding of Falcon Heavy's ambitious launch and to grasp the caliber of this megarocket, it is worthwhile to look at the numbers: 5 million: The lbs. of thrust that Falcon Heavy will generate at liftoff. If it succeeds, Falcon Heavy will be the most powerful rocket to launch since NASA's Saturn V — the iconic vessel that, with 7.5 million lbs. of thrust, accomplished the definitive Apollo-era feat of putting astronauts on the moon. According to Musk, Falcon Heavy is "twice as powerful as any other booster operating today," a comment that alludes to the modern-day space race between SpaceX and American flight company Boeing to win the opportunity of flying astronauts to the International Space Station.

This translates to about 70 meters tall. 140,700 - The payload size capability of the Falcon Heavy rocket in lbs. (equivalent to 63,800 kilograms). This is more than twice what its competitor, United Launch Alliance's Delta IV Heavy Booster, can transport. 3: The number of Falcon 9 rockets effectively being merged to become Falcon Heavy. SpaceX's new megarocket comprises two Falcon 9 first-stage boosters attached to a core booster, which itself is an altered version of a standard Falcon 9. 27: The number of Merlin first-stage engines that, firing in unison, will produce Falcon Heavy's powerful thrust. They are divided evenly among the three main boosters, with nine engines on each booster. SpaceX founder and CEO Elon Musk has said there's a good chance the Falcon Heavy rocket won't survive its upcoming liftoff, and that includes its cargo. "I hope it makes it far enough away from the pad that it does not cause pad damage," he said at a conference in July 2017.

SpaceX representatives confirmed that once the three boosters separate, the two side cores will attempt to land at Cape Canaveral Air Force Station while the core booster will attempt to land on the "Of Course I Still Love You" drone ship, stationed in the Atlantic Ocean. The boosters are equipped with fins and landing legs to control re-entry through the atmosphere. 21: The number of times that SpaceX Falcon 9 boosters have landed back on Earth, either at a designated landing zone or on robotic drone ships at sea. Six of those rockets have been reused on subsequent SpaceX launches. 6: The total of counties in central Florida that might hear a sonic boom as the two Cape Canaveral-bound boosters, from each side of Falcon Heavy, attempt controlled landings as they re-enter Earth's atmosphere. SpaceX representatives stated there's a possibility that "residents of Brevard, Indian River, Orange, Osceola, Seminole, and Volusia counties may hear one or more sonic booms during the landing attempts." 1: One mannequin will be sitting in the driver's seat of the Tesla Roadster that Falcon Heavy aims to launch into heliocentric orbit. Musk introduced an image of the dummy, called "Starman," via Instagram on Feb. 2. SpaceX will additionally pay homage to the late musician David Bowie by playing his song "Space Oddity" in the car as it travels through space.
