SpaceX’s Falcon 9 is targeting the launch of 24 Starlink satellites to low-Earth orbit from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California.
A live webcast of this mission will begin about five minutes prior to liftoff, which you can watch here and on X @SpaceX. You can also watch the webcast on the new X TV app.
This will be the first flight for the Falcon 9 first stage booster supporting this mission. After stage separation, the first stage will land on the Of Course I Still Love You droneship, which will be stationed in the Pacific Ocean.
There is the possibility that residents of Santa Barbara, San Luis Obispo, and Ventura counties may hear one or more sonic booms during the launch, but what residents experience will depend on weather and other conditions.
