A Falcon 9 rocket carrying the next set of Starlink satellites could lift off early Saturday morning from Vandenberg Space Force Base, pushing the total number of spacecraft sent into orbit above 5,300.

Liftoff of the SpaceX rocket is scheduled to take place between 11:19 p.m. Friday and 3:39 a.m. Saturday from Space Launch Complex-4 on the South Base, according to one advisory issued ahead of Vandenberg missions.

On Friday afternoon, SpaceX would aim for 12:47 a.m. with three backup opportunities starting at 1:23 a.m. and ending at 3 a.m.

If the countdown gets delayed for any reason, six backup opportunities are also currently available starting at 11:26 p.m. Saturday until 2:50 a.m. Sunday.

The first-stage booster will return to land on the Of Course I Still Love You droneship positioned several hundred miles away from the Central Coast. 

Launch times are determined by where the satellites need to be placed in space.

While Central Coast residents will hear the rocket’s departure, they won’t hear sonic booms since the landing won’t take place at Vandenberg. 

West Coast Starlink missions typically involve 21 Starlink satellites. 

The Vandenberg launch will follow another mission that delivered 22 Starlink satellites from the East Coast on Tuesday.

Jonathan McDowell, who keeps a detailed tally of man-made objects in space, said the Florida launch pushed the total number of Starlink satellites to 5,287. McDowell is an astronomer and astrophysicist at the Harvard-Smithsonian Center for Astrophysics.

According to his tally, the total number of working Starlink satellites sits at 4,895.

SpaceX has said the Starlink constellation to provide Internet access to remote and rural areas would have approximately 30,000 satellites. 

Live webcasts of each mission are scheduled to begin on the SpaceX account of the site formerly known as Twitter about five minutes before liftoff.
