The launch of a SpaceX Falcon 9 rocket from Vandenberg Space Force Base is planned for Friday.
The launch, which will deploy 51 Starlink satellites, is set for liftoff at 11:12 a.m.
It will be SpaceX's third launch from Vandenberg this year.
Starlink is SpaceX's high-speed broadband satellite internet service designed to reach rural and remote communities.
Following stage separation, SpaceX plans to land the rocket's first stage booster on the "Of Course I Still Love You" drone ship stationed in the Pacific Ocean.
The same booster was previously used to launch Sentinel-6 Michael Freilich, DART, and six Starlink missions.
If for some reason the launch is delayed, the base plans to try the launch on Saturday at 10:58 a.m.
A live stream of the launch will begin about five minutes before liftoff.
