Iridium-6/GRACE-FO Mission

On Tuesday, May 22nd at 12:47 p.m. PDT, SpaceX successfully launched five Iridium® NEXT satellites and two GRACE-FO satellites from Space Launch Complex 4E (SLC-4E) at Vandenberg Air Force Base, California. Liftoff occurred at 12:47 p.m. PDT, or 19:47 UTC. The GRACE-FO satellites were deployed about eleven minutes and thirty seconds after launch, followed by the deployment of the five Iridium® NEXT satellites about an hour after launch.

Falcon 9’s first stage for the Iridium-6/GRACE-FO mission previously supported the Zuma mission from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station in January 2018. SpaceX did not attempt to recover Falcon 9’s first stage after launch. You can watch a replay of the launch webcast below and find out more about the mission in our press kit.
