Photos: Atlas 5 rocket aims for International Space Station

Stormy weather at the Kennedy Space Center forced SpaceX to scrub the liftoff of a Falcon Heavy rocket Thursday night carrying the ViaSat 3 Americas broadband satellite to a near-geostationary orbit.

After calling a hold less than a minute before liftoff Friday, SpaceX launched the Maxar-built SXM 7 radio broadcasting satellite for SiriusXM Sunday. A Falcon 9 rocket lifted off from pad 40 at Cape Canaveral at 12:30 p.m. EST (1730 GMT).

More than three years after its launch was delayed by a corporate merger, a commercial Earth-imaging satellite has finally shipped to its California rocket base for liftoff aboard an Atlas 5 in September.
