SpaceX livestreams Falcon 9 launch to put 60 compact satellites into orbit

SpaceX sent 60 compact satellites into low Earth orbit on Thursday, livestreaming the event on Twitter. Video footage showed the rocket's boosters blazing a furious trail through the sky, to station the satellites as part of a constellation of networked devices known as Starlink.

SpaceX founder and chief executive Elon Musk plans to ultimately launch thousands of these compact flat-panel satellites to provide global internet service. Each spacecraft weighs just 260 kilograms.

The Starlinks are initially placed in a relatively low orbit of 290 kilometre, easily visible as a long, strung-out cluster parading through the night sky.

Over a few months, krypton-powered thrusters raise the satellites to a 550km orbit.

The service may start later this year in the northern US and Canada, then expand to the world's most populated areas after 24 launches.
