SpaceX Sets 25-Starlink Launch From Vandenberg, With Potential Sonic Booms

SpaceX is prepping to launch 25 Starlink satellites from Vandenberg Space Force Base on March 20, 2026, using a Falcon 9 first stage on its fourth flight, with a mission window from 2:48 a.m. to 6:48 p.m. PT and a planned droneship landing on ‘Of Course I Still Love You’ in the Pacific. A live webcast will cover liftoff, and residents of Santa Barbara, San Luis Obispo, and Ventura counties may hear sonic booms depending on weather and trajectory. The ECOBOOM acoustic study, conducted with BYU and CSU Bakersfield, aims to better understand ground-level sound from launches amid ongoing outreach to affected communities.
