Photos: Atlas 5 rocket aims for International Space Station

A high-throughput communications satellite developed as a joint venture between Telesat and APT Satellite lifted off on top of a SpaceX Falcon 9 rocket at 12:45 a.m. EDT (0445 GMT) Monday from Cape Canaveral, following a delay to wait for storms to clear the Florida spaceport.

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.

The next Delta 4-Heavy rocket was raised vertical Friday at Cape Canaveral, signaling the start of a comprehensive series of pre-flight tests before liftoff next year with a top secret U.S. government spy satellite.
