Why SpaceX’s Falcon Heavy Is Such a Big Deal

SpaceX has given the world a first look at its most powerful rocket yet – theFalcon Heavy. Not only is this beast the most powerful rocket that the Elon Musk-led SpaceX ever made, it will be “the most powerful operational rocket in the world by a factor of two,” according to their site.

Sharing the rocket’s photos and video on Twitter and Instagram, SpaceX put the space vehicle’s might in perspective, saying it’s equal to eighteen 747 aircraft “at full power”.

“With more than 5 million pounds of thrust at liftoff — equal to approximately eighteen 747 aircraft at full power — Falcon Heavy will be the most powerful operational rocket in the world by a factor of two,” SpaceX reps wrote.

To get that 5 million pounds of thrust and liftoff, the two-stage rocket has27 first-stage Merlin engines, as states SpaceX.  That’s three times as many engines as are on SpaceX’s current workhorse rocket – the Falcon 9.

In fact, the first stage for the Falcon Heavy essentially involves three Falcon 9 cores strapped together. The reusable boosters will get it into orbit, then fly back to Earth and land vertically like other Falcon 9s. The second stage will be powered by just one Merlin engine, same as the Falcon 9.

The new monster spacecraft will be able to lift into orbit over 54 metric tons (119,000 lbs), which is a “mass equivalent to a 737 jetliner loaded with passengers, crew, luggage and fuel” to continue the airplane comparisons. This capacity is the largest since the Saturn V rocket of the Apollo lunar program, which could carry 310,000 pounds to low-Earth orbit.

What will be the payload on the rocket’s maiden journey? As Musk announced cheekily in a December 2017 Instagram post, the rocket will carry none other than the original Tesla Roadster on its test flight. And it will be “playing Space Oddity, on a billion year elliptic Mars orbit,” he added.

Falcon Heavy is slated to take off from the Kennedy Space Center in Florida later in January 2018, barring delays. You can follow the launch schedule here.
