Starlink is a satellite-based internet system that SpaceX has been building for years to bring internet access to underserved parts of the world.
A SpaceX rocket launch from the Santa Barbara County coast has been postponed from Tuesday to Thursday.
The Falcon 9 launch out of Vandenberg Space Force Base will usher 27 Starlink satellites into low-Earth orbit. Liftoff is scheduled for 3:54 p.m. with backup opportunities available until 7:54 p.m.
After separation, the first stage booster landed on the Of Course I Still Love You droneship in the Pacific. People in Santa Barbara, San Luis Obispo, and Ventura counties may hear one or more sonic booms.

The rocket and its exhaust plume are sometimes visible for hundreds of miles as it soars along the coast, if skies are clear and light conditions are right. Launches just after sunset and before sunrise usually provide the best views as the rocket reflects the sun's rays against the backdrop of a darkened sky.
SpaceX has a Starlink constellation of satellites orbiting Earth about 340 miles up, shuttled into space by the company's rockets. The Starlink network is designed to deliver high-speed internet anywhere around the globe.
If light conditions are right, the satellites appear in a train as they parade across the night sky. The satellites are sometimes visible in the first few minutes after sundown and before sunrise when the sun is below the horizon, but the satellites are high enough to reflect direct sunlight.
