Launches from Vandenberg, outside Lompoc, and the spiraling exhaust trails they leave behind are often visible across Southern California. Loud booms from Falcon 9's reusable first stage can rattle local windows as the stage angles for a landing on an autonomous barge off the California coast.

The final Falcon 9 launch of Starlink low-orbiting satellites from California this year is scheduled for liftoff this weekend, according to SpaceX. The launch window for 22 internet communication system satellites is between 5:48 p.m. and 9:31 p.m. PST. on Saturday, Dec. 28, from Vandenberg Space Force Base.

SpaceX is hoping to get in two more rocket launches before the year comes to a close − which will bring the record year in Florida to 93 launches. Federal Aviation Administration warnings show two possible launches in the coming days: Another attempt at the Astranis mission and the SpaceX Starlink 12-6 mission.
