Final SpaceX rocket launch of 2017 lights up Southern California sky

LOS ANGELES -- Did you see something bright in the sky? You may have seen the launch of the 18th, and final mission of the year for SpaceX Friday night.

The launch happened moments ago right here in Southern California at Vandenberg Air Force Base.

This mission sends 10 satellites into orbit, using another used Falcon 9 rocket for the flight.

SpaceX says this is the fourth flight for long-time customer Iridium.

Both companies are under contract to launch a total of 75 satellites to provide communications services for regions all over the world.
