The V moon rocket, last flown in 1973,

The human race has indeed come a long way since the invention of combustion engines to inter-planetary and interstellar travels. Space tech, too, finds itself on a new level since the USSR sent the Vostok 3KA rocket with Yuri Gagarin on April 12, 1961. SpaceX’s innovation of re-flights of rockets took space tech to another pedestal. NASA’s Space Shuttle, used from 1981 to 2011, completing a total of 135 missions used to be the most powerful rocket with 24,000 kilograms of payload in the Low Earth Orbit (LEO). Yes, used to be.SpaceX’s Falcon Heavy, launched on Month Day, 2018 surpassed Space Shuttle by more than a factor of 2 with 63,800 kilograms of payload in the LEO. The Falcon Heavy is the most capable rocket flying with more than 5 million pounds of thrust at liftoff. That means, if we compare the liftoff thrust with the 747 aircraft at full power, the Falcon is equal to eighteen of the 747s. If we talk about orbit payload delivery, only Saturn V moon rocket, last flown in 1973, delivered more orbit payload than Falcon Heavy. This heavy lift vehicle by SpaceX is capable of lifting the equivalent of a 737 jetliner flying passengers, luggage and even the fuel.The first stage of the Falcon is made of three cores, with 27 Merlin engines to fire it up. The two boosters, or the side cores are connected at the base and at the top of the center core’s liquid oxygen tank. The central core engines, however, are throttled down shortly after the liftoff. They throttle back up to full thrust as the side cores separate.The second stage of the Falcon Heavy has one Merlin engine which is identical to its counterpart on Falcon 9, on which the Falcon Heavy draws its design from. It maximizes reliability and helps in minimizing stage separation events. After the main engines cutoff and the first stage cores, or the boosters separate, the second stage delivers the rocket’s payload to orbit after the main engines cut off and the first-stage cores separate. The payloads can be placed into a variety of orbits including Low Earth Orbit (LEO), Geosynchronous Transfer Orbit (GTO) and the Geosynchronous Orbit (GSO).The “Heavy” missions will be delivering large payloads to orbit inside a composite fairing, but the rocket is capable of carrying SpaceX’s own spacecraft Dragon as well.  An interesting fact about payloads is the fact that SpaceX Founder and CEO Elon Musk sent his personal Tesla Roadster as the payload in the maiden flight of the Falcon Heavy. He posted a picture of the car in December 2017 saying that the traditional way of sending mass simulators, which are in the form of concrete or steel blocks seemed “boring”. And according to Mr Musk, anything that is boring is terrible and that is the reason the company  decided to send something unusual. Also, Elon mentioned that the cherry-red Tesla will be playing Space Oddity on the Mars orbit.SpaceX had expected the maiden flight to have been in 2013-14. Although the plans were announced in a conference in April 2011, the concepts were discussed since about 2004. In an interview in July 2017, Elon Musk stated that the project was way more difficult that they thought and were pretty naive about that. The fact that Falcon Heavy isn’t supported by government finances at all seems pretty intriguing. Private capital is all there is. The vehicle is majorly based on its brother Falcon 9 which has proved to be a great success. Following the success, SpaceX announced Falcon Heavy on April 5, 2011 and later unveiled some plans to expand the manufacturing capacity.
