SpaceX’s Saturday smallsat Starlink Mission 17-9 launch from foggy California

September 7, 2025

On Saturday, September 6 at 11:06 a.m. PT, Falcon 9 launched 24 Starlink satellites to low-Earth orbit from Space Launch Complex 4 East (SLC-4E) from Vandenberg Space Force Base in California. Photos captured by Satnews.

The flight expanded SpaceX‘s constellation to almost 9,000 units that comprise the network.

This was the 20th flight for the first stage booster supporting this mission, which previously launched SDA-0A, SARah-2, Transporter-11, and now 17 Starlink missions. Following stage separation, the first stage landed on the Of Course I Still Love You droneship, which was stationed in the Pacific Ocean.

There was the possibility that residents of Santa Barbara, San Luis Obispo, and Ventura counties may have heard one or more sonic booms during the launch, but what residents experienced depended on weather and other conditions.

SpaceX’s Falcon 9 is targeting the launch of 24 Starlink smallsats to join the Starlink constellation in low-Earth orbit from Space Launch Complex 4 East (SLC-4E) from Vandenberg Space Force Base in California.

A live webcast of this mission will begin about five minutes prior to liftoff, which you can watch on X @SpaceX. You can also watch the webcast on the new X TV app.

The forecast calls for a temperature of 63°F, few clouds, 22% cloud cover and a wind speed of 2mph.
