Live coverage: SpaceX finally launches Falcon 9 rocket

A hefty new satellite to beam SiriusXM radio programming across North America rode a SpaceX Falcon 9 rocket into orbit Sunday from Cape Canaveral on course to replace an aging broadcast station launched more than 15 years ago.

SpaceX and SES, owner of a 5.8-ton commercial telecom satellite poised for launch from Cape Canaveral on Wednesday, struck a deal to tweak the Falcon 9 rocket’s launch profile to give the SES 9 spacecraft a stronger push toward its operating post more than 22,000 miles above Earth.
