SpaceX’s Falcon Heavy rocket is currently the most powerful launch system on Earth and Elon Musk puts his own midnight cherry Tesla Roadster as The dummy payload on its maiden flight. The car is bound for Mars orbit but first, the upper-stage rocket of Falcon Heavy has to survive about six hours of punishing radiation.

Falcon Heavy Rocket

falcon heavy,All About Falcon Heavy Rocket that You Should KnowFalcon Heavy is designed and manufactured by SpaceX. Falcon Heavy rocket is a reusable super heavy-lift launch vehicle, it is said reusable because its rockets are bound to come back to a certified region on earth after getting the payload to its path.

The rocket is consists of a Falcon 9 rocket core and it consists of two additional Falcon 9 first stages as strap-on boosters which makes the increase in the low Earth orbit (LEO) maximum payload to 63,800 kg from 22,800 kg for a Falcon 9 Full Thrust and compared to 140,000 kg for the Saturn V and 27,500 kg for the now-retired NASA Space Shuttle. The Falcon Heavy rocket is just a variant of the Falcon 9 vehicle.

Falcon Heavy rocket is functioned for the Orbital super heavy-lift launch vehicle manufactured by SpaceX.
If we talk about the size of the Falcon Heavy rocket, the height of the Falcon Heavy rocket is 70 mt (230 ft), the diameter of the Falcon Heavy rocket is 3.66 mt (12.0 ft), the width of the Falcon Heavy is 12.2 mt (40 ft), the mass of the Falcon Heavy rocket is 1,420,788 kg (3,132,301 lb). And there 2+ stages in the Falcon Heavy rocket.
The Falcon Heavy rocket is capacitive enough to place payload of 63,800 kg (140,700 lb) to Low Earth orbit (LEO), and payload of 26,700 kg (58,900 lb) to Geostationary transfer orbit (GTO), and payload of 16,800 kg (37,000 lb) to Mars and payload of 3,500 kg (7,700 lb) to Pluto.

Design of the Falcon Heavy Rocket

The Rocket is based on the Falcon 9 as its heavy configuration consists of a structurally-strengthened Falcon 9 as the “core” component and it consists with two more Falcon 9 first stages acting as liquid fuel strap-on boosters which increases the low Earth orbit (LEO) maximum payload to 63,800 kilograms.

Falcon Heavy rocket was designed so it can be fully reusable as both the center core and side boosters carry landing legs which make each core to land safely on Earth after the takeoff.
Aluminum-lithium alloy is used to make the tanks of Falcon Heavy’s three first-stage cores and the second stage which is stronger and lighter than aluminum by the addition of lithium.

First Stage

CORES                       : 3
ENGINES                    : 27
THRUST AT SEA LEVEL : 22,819kN (5,130,000 lb)
THRUST IN VACUUM    : 24,681kN (5,548,500 lb)

The first stage of Falcon Heavy rocket is powered by the three Falcon 9 derived cores and each one of them is equipped with nine Merlin 1D engines. The side cores are connected at the top of center core’s liquid oxygen tank and at the base.

The stage consists of the three cores with a total of 27 Merlin engines can generate 22,819 kilonewtons (5.13 million pounds) of thrust at liftoff at the sea level while thrust rises to 24,681 kN (5,549,000 lb) as the craft climbs out of the atmosphere.

The center core of the first stage throttles to full power for a few seconds at the time of launch for the for additional thrust, then throttles down which allows a longer burn time and After the side boosters separate, the center core again throttles back up to maximum thrust.

The upper stage of the Falcon Heavy rocket is powered by a single Merlin 1D engine modified for vacuum operation which can produce a thrust of 934 kN (210,000 lb) and an expansion ratio of 117:1 and the nominal burn time is 397 seconds.

Carbon fiber aluminum core composite structure is used to make the interstage connects the upper and lower stage for Falcon 9 and for the engine to restart again and again the engine has dual redundant pyrophoric igniters (TEA-TEB).

The three cores of the Falcon Heavy rocket arrange the engines in an Octaweb type of structural form to make the manufacturing process streamlined. Each of the cores has four landing legs covering a large area (these legs are made by carbon fiber with the aluminum honeycomb) and small grid fins are used to control the downward motion of the boosters and center core through the atmosphere these fins deploy from the vehicle after separation.

After the separation of the side booster’s the center engine in each core starts burning only for a few sec. to make the trajectory of booster’s safely away from the rocket and then the legs deploy as the boosters come back to earth landing each one of them softly on the earth.

Second Stage

ENGINE                  : 1
BURN TIME             : 397sec
THRUST IN VACUUM: 934kN (210,000 lb)

The second stage of the Falcon Heavy rocket is simply a shorter version of the first tank. This stage of the Falcon Heavy rocket uses most of the same material, tooling and manufacturing techniques. After the main engines cut off and the first-stage cores separate the second stage Merlin engine gets the payload to orbit.

To get the payloads into the low earth orbit (LEO), geosynchronous transfer orbit (GTO) and geosynchronous orbit (GSO) and into other variety of orbits the engine of the stage can be restarted many times.

The second stage of the Falcon Heavy rocket consists of 1 Merlin 1D Vacuum engine produce a total amount of 934 kN (210,000 lb) thrust and creates a total time of 348 seconds Specific impulse. And the burning time of the second stage engine is 397 seconds.


There are two boosters in the Falcon Heavy rocket and each of the Falcon Heavy’s side cores, or the boosters, is equivalent to the first stage of a Falcon 9 rocket with the nine Merlin engines which able to produce thrust of 7.6 MN (1,700,000 lb) (each) at sea level and 8.2 MN (1,800,000 lb) (each) of thrust at the vacuum and hence the total thrust of 15.2 MN (3,400,000 lb) at sea level and 16.4 MN (3,700,000 lb) of thrust at the vacuum.

These boosters give the Specific Impulse of 282 seconds at the sea level and produce 311 seconds of Specific Impulse at the vacuum. And the burning time of them is 154 seconds.

Elon Reeve Musk born on June 28, 1971, in Pretoria, Transvaal, South Africa, is a South African-born Canadian American business magnate, inventor, engineer and investor. He is the founder of SpaceX and he is also the CEO and lead designer of SpaceX and also the co-founder, CEO and product architect of Tesla, Inc.; and chairman of SolarCity.

Mother of the Elon Musk is Maye Musk, a model and dietician from Regina, Saskatchewan, Canada, and Father of the Elon Musk is Errol Musk, a South African electromechanical engineer, pilot, and sailor. He has two siblings one younger brother-Kimbal born in 1972 and a younger sister-Tosca born in 1974.

Musk was an avid reader during his childhood and he taught himself computer programming at the age of 12 and sold the code of a BASIC-based video game he created called Blastar to a magazine for approximately $500.

Musk moved to Canada in June 1989 at the age of seventeen to attend Queen’s University and after 2 years in 1992, he was transferred to the University of Pennsylvania where in 1997 he received a degree in physics from the College of Arts and Sciences and an economics degree from the Wharton School.

At the age of 24 Musk moved to California to begin a Ph.D. in applied physics and materials science at Stanford University but dropped out after 2 days to pursue an entrepreneurial career in the areas of the internet, renewable energy, and outer space.

After some time in the year of 1999, he co-founded Zip2 which was a web software company later the company was acquired by Compaq for $340 million. Then Musk founded, an online payment company which merged with Confinity in 2000 and became PayPal later which was bought by eBay for $1.5 billion in October 2002.

In the same year, Musk founded SpaceX, an aerospace manufacturer, and space transport services company in may 2002. Also, he is the CEO and lead designer of SpaceX. And in 2003, he co-founded Tesla, Inc., an electric vehicle and solar panel manufacturer

Recently in February 2018 he is listed as the 53rd richest person in the world with a net worth of $20.1 billion in the Forbes and was ranked 21st on the Forbes list of The World’s Most Powerful People in December 2016.
