You are witnessing the world's most powerful rocket in flight right now
The Falcon Heavy, which has Elon Musk's personal Tesla on board, is the most powerful rocket.
SpaceX has said the rocket will be capable of sending humans to Mars (though SpaceX has plans to build a different rocket/spaceship system for Mars travel, called the BFR).
Musk himself said this launch could fail -- and if it did, it would be the "best fireworks display."
