New York (CNN Business) SpaceX just vaulted a rocket full of 60 satellites into the sky, marking a huge leap forward on its mission to put up a megaconstellation that could beam cheap broadband all over the planet.

This is the first dedicated mission for SpaceX's internet constellation, called Starlink. It kicked off when the company's towering Falcon 9 rocket blazed toward the sky from a launch pad at Cape Canaveral Air Force Station at 10:30 pm ET.

Around 11:30 pm ET, the second stage of the rocket deployed what's called a payload stack — holding all 60 satellites. It slowly began to drop the individual satellites into orbit.

Musk said the satellites would fan out in a way that will look like "spreading a deck of cards on a table."

He confirmed in a tweet not long after deployment that all 60 satellites were "online," and that the devices would soon spread out their solar arrays, which power the satellites while in orbit.
