The Falcon 9 mission, launched from Vandenberg Air Force Base in California at 8:27 p.m. Eastern in an instantaneous launch window, was the fourth of eight missions for Iridium, carrying the McLean, Virginia-based operator’s second generation satellites, called Iridium Next.

In what now is considered a rarity, SpaceX opted not to recover the rocket’s first stage, instead letting the booster fall into the Pacific Ocean. SpaceX has recovered 20 out of 42 first stage Falcon 9 boosters to date, with the first success following the launch of 11 Orbcomm satellites to low Earth orbit (LEO) in December 2015. Today’s launch was SpaceX’s fifth with a previously flown Falcon 9, using a first stage that had launched the second batch of 10 Iridium Next satellites back in June.

This was the fourth set of 10 satellites in a series of 75 total satellites that SpaceX will launch for Iridium’s next generation global satellite constellation, Iridium® NEXT.
