SXM 7

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 called off the planned launch of a Falcon 9 rocket Friday at Cape Canaveral, halting the countdown less than a minute before liftoff to allow time to perform additional ground system checkouts before the mission’s next launch opportunity no earlier than Sunday.

A massive radio broadcasting satellite for SiriusXM is set for liftoff Friday on top of a Falcon 9 rocket, punctuating a busy week for SpaceX that included the debut of a new-generation cargo ship for the International Space Station and a spectacular atmospheric test flight of a prototype rocket over South Texas.
