About Space X
Space Exploration Technologies Corp., doing business as SpaceX, is a private American aerospace manufacturer and space transport services company.  It was founded in 2002 with the goal of reducing space transportation costs and enabling the colonization of Mars.  SpaceX has since developed the Falcon launch vehicle family and the Dragon spacecraft family, which both currently deliver payloads into Earth orbit.

Headquartered - Hawthorne, California
CEO – Elon Musk
Products – Falcon launch vehicles Dragon capsules ASDs landing platform

About Falcon Heavy
•    Falcon Heavy is a reusable super heavy-lift launch vehicle designed and manufactured by SpaceX. The Falcon Heavy (which was earlier described as the Falcon 9 Heavy) is a variant of the Falcon 9 vehicle and consists of a strengthened Falcon 9 rocket core with two additional Falcon 9 first stages as strap-on boosters.
•    This increases the low Earth orbit (LEO) maximum payload to 63,800 kilograms (140,700 lb), compared to 22,800 kilograms (50,300 lb) for a Falcon 9 Full Thrust, 27,500 kilograms (60,600 lb) for the now-retired NASA Space Shuttle and 140,000 kilograms (310,000 lb) for the Saturn V.
•    The Falcon Heavy is the world's 4th highest capacity rocket ever to be built, after Saturn V, Energia and N1, and the highest capacity rocket in current operation as of February 6, 2018, superseding the Delta IV Heavy payload by more than double.
•    SpaceX successfully launched the Falcon Heavy on February 6, 2018, at 3:45 p.m.  The dummy payload on its maiden flight was SpaceX founder Elon Musk's Tesla Roadster.

Design of Falcon Heavy
•    Falcon Heavy is the most powerful operational rocket in the world by a factor of two. With the ability to lift into orbit nearly 64 metric tons (141,000 lb) – a mass greater than a 737 jetliner loaded with passengers, crew, luggage and fuel – Falcon Heavy can lift more than twice the payload of the next closest operational vehicle, the Delta IV Heavy, at one-third the cost. Falcon Heavy draws upon the proven heritage and reliability of Falcon 9..
•    Its 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 approximately eighteen 747 aircraft. Only the Saturn V moon rocket, last flown in 1973, delivered more payload to orbit. 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.

Falcon Heavy missions will deliver large payloads to orbit inside a composite fairing, but the rocket can also carry the Dragon spacecraft.

Second Stage
Falcon Heavy draws upon Falcon 9’s proven design, which minimizes stage separation events and maximizes reliability. The second-stage Merlin engine, identical to its counterpart on Falcon 9, delivers the rocket’s payload to orbit after the main engines cut off and the first-stage cores separate. The engine can be restarted multiple times to place payloads into a variety of orbits including low Earth, geosynchronous transfer orbit (GTO) and  geosynchronous orbit (GSO).

Engine – 1
Burn Time- 397 sec
Thrust in Vaccum – 934 kN

First Stage
Three cores make up the first stage of Falcon Heavy. The side cores, or boosters, are connected  at the base and at the top of the center core’s liquid oxygen tank. The three cores, with a total of 27 Merlin engines, generate 22,819 kilonewtons (5.13 million pounds) of thrust at liftoff. Shortly after liftoff the center core engines are throttled down. After the side cores separate, the center core engines throttle back up to full thrust.

Cores – 3
Engines – 27
Thrust at sea level – 22819kN
Thrust in Vaccum – 24, 681 kN

Each of Falcon Heavy’s side cores, or boosters, is equivalent to the first stage of a Falcon 9 rocket with nine Merlin engines. At liftoff, the boosters and the center core all operate at full thrust. Shortly after liftoff, the center core engines are throttled down. After the side cores separate, the center core engines throttle back up.

Three Nine – Engine Cores
Inside each of Falcon Heavy’s three cores is a cluster of nine Merlin engines.  These same engines power Falcon 9, enabling efficiencies that make Falcon Heavy the most cost-effective heavy-lift launch vehicle in the world. With a total of 27 first-stage engines, Falcon Heavy has engine-out capability that no other launch vehicle can match—under most payload scenarios, it can sustain more than one unplanned engine shutdown at any point in flight and still successfully complete its mission.
