A SpaceX rocket launch is scheduled to take place this Friday at Vandenberg Space Force Base.
The Falcon 9 rocket is set to take off at 12:21 p.m.
It will be carrying 52 Starlink satellites into low-Earth orbit. Starlink is SpaceX's high-speed broadband satellite internet service designed to reach rural and remote communities.
If the launch is scrubbed for any reason, there are backup launch opportunities at 4:19 p.m. Friday, 12:07 p.m. Saturday, and 4:05 p.m. Saturday.
Following stage separation, about eight minutes after liftoff, SpaceX plans to land the rocket's first stage booster on the Of Course I Still Love You droneship stationed in the Pacific Ocean. The booster being used in this launch was used for seven previous missions.
A live webcast of the launch is scheduled to begin about five minutes prior to liftoff.
This will be SpaceX's fifth launch from Vandenberg this year.
