SpaceX is planning a launch out of Vandenberg Space Force Base on Saturday night.
Base officials say the launch window for the Falcon 9 rocket carrying 24 Starlink satellites into low Earth orbit will begin at 7:05 p.m. and continue through 11:05 p.m.
The launch is on behalf of the Department of Defense.
The first-stage booster will land on a droneship in the Pacific Ocean.
A live webcast of the mission will begin about five minutes prior to lift-off.
This will be the fifth flight for the first-stage booster supporting this mission.
