SpaceX CEO Elon Musk said in a tweet after the static fire test that the heavy lift rocket's maiden voyage could happen in "a week or so", although launches usually happen about two weeks after a static fire text.
Photos posted by SpaceX chief executive Elon Musk then showed the new rocket inside its Florida hangar.
SpaceX's Falcon Heavy was tested in its own launch side LC-39A at NASA's Kennedy Space Center in Cape Canaveral, Florida. The first flight has been delayed by several years. The Falcon Heavy is essentially three of the California-based company's Falcon 9 rockets put together, with 27 Merlin engines instead of nine.
But hype surrounding the upcoming demonstration flight has been partially energized by a special payload encapsulated in the rocket's protective nose cone, or fairing - Musk's personal 2008 Tesla Roadster, an all-electric sports auto, will be hurtled into deep space.
According to the Verge, the Falcon Heavy will carry Elon Musk's personal Tesla roadster as its virgin payload, carrying the electric vehicle into an orbit around the sun that is the same distance away as Mars' orbit.

An unexpected uptick in United Kingdom weekly earnings in the three months to November prompted the Euro to Pound (EUR/GBP) exchange rate to slump sharply.
The first payload for the Falcon Heavy, however, is just a fun one. It also has three times more engines.
SpaceX intends to land the rocket's boosters back on Earth after launch - as is the company's usual practice today with the Falcon 9 - and that necessarily negates some performance.
For the test flight, however, SpaceX is going much crazier.
The Falcon Heavy can carry one of the largest payloads in the history of space travel. Musk has repeatedly warned the rocket could explode.
