In an early morning Twitter post, Musk revealed several views of the new rocket under assembly inside SpaceX's hangar at Pad 39A of NASA's Kennedy Space Center in Cape Canaveral, Florida. The images show stunning views of the Falcon Heavy from above and one imposing shot of the rocket's 27 first-stage engines, nine on each of its three main boosters.

"Falcon Heavy at the Cape," Musk wrote in the Twitter post.
SpaceX's Falcon Heavy is a heavy-lift launch vehicle powered by two first-stage boosters from the company's Falcon 9 rockets and a central core booster that itself is a modified Falcon 9. The rocket will stand 230 feet (70 meters) tall when complete and is designed to launch payloads of up to 119,000 lbs. (57 metric tons) into space.
