SpaceX will try to land the Falcon's first stage on an autonomous vessel floating in the ocean.
The payload is the eighth and final set of satellites to be launched as Iridium replaces its entire globe-circling fleet with next-generation orbiters. Deployment of the satellites is scheduled to be completed a little over an hour after liftoff.

After launching the satellites, the Falcon 9 rocket successfully returned to land on solid ground near the launch site rather than at sea. The satellites will become part of a six-satellite constellation that will work in tandem with an Italian constellation known as COSMO-SkyMed.

If successful, Iridium will have a total of 75 new satellites in orbit, including nine spares.
