You can actually see city lights and some lightning down below on the payload camera.

Fifth satellite is away, and that concludes this afternoon's mission.

53 successes out of the 55 conducted since June 2010 give Falcon 9 a 96.36% success rate.

Nice view of the fourth departing.

Reminder to all. No congrats on this thread. Use the Party and Discussion threads.

As the webcast comes to a close, I'll also sign off as well.

SpaceX's next mission will involve a Falcon 9 Block 4 launching SES-12, the customer's largest satellite, from Cape Canaveral on May 31st. From Vandenberg Air Force Base, good afternoon.

GRACE-FO Launch

NASA Jet Propulsion Laboratory
Streamed live 2 hours ago

Upcoming Broadcast: Launching NASA's GRACE-FO
May 22 at 12:15 p.m. PDT (3:15 p.m. EDT)
Launch expected no earlier than 12:47 p.m. PDT (3:47 p.m. EDT)

A joint mission with the German Research Centre for Geosciences (GFZ), GRACE-FO will provide critical measurements that will be used together with other data to monitor the movement of water masses across the planet and mass changes within Earth itself. Monitoring changes in ice sheets and glaciers, underground water storage, and sea level provides a unique view of Earth's climate and has far-reaching benefits. The mission is planned to fly at least five years.

The satellites will launch on a SpaceX Falcon 9 rocket no earlier than 12:47 p.m. PDT (3:47 p.m. EDT) May 22 from Space Launch Complex-4E at Vandenberg. GRACE-FO will share its ride to orbit with five Iridium NEXT communications satellites as part of a commercial rideshare agreement.

JPL manages the GRACE-FO mission for the agency's Science Mission Directorate in Washington. GFZ contracted GRACE-FO launch services from Iridium, and SpaceX is providing the Falcon 9 launch service.

We have good telemetry from all 5 Iridium NEXT satellites - and got it on the first pass! Thank you @SpaceX! Thank you @Thales_Alenia_S! Complete success!
