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.
