SpaceX has launched a rocket carrying the first 60 satellites of its "Starlink" constellation, which is intended to provide internet from space in an array that could one day contain over 12,000 orbiting transponders. One of the company's Falcon 9 rockets blasted off without incident from Cape Canaveral in Florida around 10:30 pm Thursday (0230 GMT Friday). An hour later, the rocket began to release the satellites at an altitude of 280 miles (450 kilometers).
