SpaceX targets October 27, 2025, for a Falcon 9 launch of 28 Starlink satellites to low-Earth orbit from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base in California. The launch window opens at 2:12 p.m. PDT and closes at 6:12 p.m. PDT.

This is the 17th flight for the first stage booster supporting this mission, which previously launched USSF-62, OneWeb Launch 20, NROL-145, and 13 Starlink missions. Following stage separation, the first stage will land on the Of Course I Still Love You droneship, which will be stationed in the Pacific Ocean.

Residents of Santa Barbara, San Luis Obispo, and Ventura counties may hear one or more sonic booms during the launch, but what they experience will depend on weather and other conditions.
