The most powerful operational rocket in the world, SpaceX's Falcon Heavy, launched its first commercial mission from Florida in a key demonstration for billionaire entrepreneur Elon Musk's space company in the race to grasp lucrative military launch contracts. The 23-story-tall Heavy, which previously launched Musk's cherry red Tesla roadster to space in a 2018 debut test flight, blasted off from Florida's Kennedy Space Center carrying its first customer payload.
