People near Vandenberg Space Force Base may hear sonic booms Thursday following SpaceXs latest launch.
The Transporter-18 mission has a 58-minute launch window opening at 11:18 a.m.
If the launch does not happen Thursday, crews will try again Friday at the same time.
Following stage separation, the Falcon 9 rockets first-stage booster is set to land at Vandenbergs Landing Zone 4.
The boosters re-entry is expected to produce sonic booms.
A live webcast of the mission will be available on SpaceXs website and on X, @SpaceX, beginning about 15 minutes before liftoff.
Vandenberg has supported more than 60 West Coast launches, many of them from SpaceX, so far this year.
