SpaceX launched a Falcon 9 rocket Saturday night from Vandenberg Space Force Base near Lompoc, Calif., It put 24 satellites into near Earth orbit in polar areas.

SpaceX aborted the launch of two communications satellites just before liftoff on Monday evening (July 21). A Falcon 9 rocket topped with two of SES' O3b mPOWER internet spacecraft was set to launch from Florida's Cape Canaveral Space Force Station at 5:27 p.m. EDT (2127 GMT) on Monday.

SpaceX, which has long deployed its Starlink satellites from Florida, is increasingly launching the missions from California. There's a good reason.
