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).

The U.S. Air Force fired a new rail-launched rocket into space from Hawaii at 10:45 p.m. EST Tuesday (0345 GMT Wednesday), but the Super Strypi vehicle failed about a minute after liftoff with 13 satellites on-board.
