This is SpaceX's fourth of eight launches in a half-a-billion-dollar contract with Iridium. The third one launched in October of this year, and most notably, this is the first Iridium NEXT flight to use a flight-proven first stage! It will use the same first stage that launched Iridium-2 in June, and Iridium-5 will also use a flight-proven booster.
