Yesterday, San Diegans who happened to look up got a surprise show. A comet-like streak cut across the skyline as a SpaceX Falcon 9 climbed out of Vandenberg Space Force Base, hauling 25 Starlink satellites into orbit and leaving a glowing white trail that looked straight out of science fiction.
The twilight liftoff carved a bright arc from the coast toward higher altitude, with a string of sharp points trailing behind it. Across the county, residents rushed to windows, patios, and social feeds, flooding local outlets with photos and video of the spectacle.
According to FOX 5 San Diego, viewers sent in images and clips from around the region, including San Marcos and Oceanside, after the Falcon 9 lit up the sky. The station also noted that the mission followed a planned Sunday attempt that was pushed to Monday, with SpaceX citing “upper-level winds” for the scrubbed try.
Mission details
Spaceflight Now lists the flight as a Falcon 9 launch from Space Launch Complex 4E at Vandenberg, carrying a batch of 25 Starlink V2 Mini satellites into low-Earth orbit. The West Coast mission used a polar inclination trajectory, a path that often turns routine launches into sky-filling twilight shows for people on the ground.
Local coverage from 10News (KGTV) reported that both the expanding exhaust plume and the “satellite train” that followed were visible across much of San Diego County.
Why it looked so bright
The dramatic glow is not a mystery to broadcasters and space watchers. The effect kicks in when a rocket climbs into sunlight shortly after local sunset, so the exhaust and upper-stage hardware stay sunlit while the ground below is already dark. That contrast turns otherwise invisible exhaust into a glowing, high-altitude cloud.
KFSN/ABC30 noted that clear skies and precise timing amplified Monday’s display, helping create the classic “jellyfish” plume that filled social feeds as quickly as it spread across the sky.
When it happened and the delay
SpaceX had originally planned to launch on Sunday, then postponed the attempt and reset for Monday. FOX 5 San Diego reports the company pointed to upper-level winds as the culprit. That brief weather-related hold was a reminder that conditions high above the surface, not just the local forecast, can decide whether a countdown turns into a light show or a rain check.
Why the launches keep coming
The flight is one in a steady stream of Starlink missions as SpaceX builds out its broadband megaconstellation. Space.com reported that the company recently crossed a milestone of more than 10,000 active Starlink satellites in low-Earth orbit.
That relentless cadence keeps Vandenberg Space Force Base busy and gives Southern California skywatchers plenty of chances to catch more twilight launches, comet-like plumes, and glowing satellite trains in the months ahead.
