CAPE CANAVERAL SPACE FORCE STATION -- SpaceX is gearing up for another Starlink launch on Monday morning.

The Falcon 9 rocket will send up Starlink 12-4 mission from Space Launch Complex 40 at Cape Canaveral Space Force Station, stated SpaceX.

The launch window will open at 11:43 a.m. ET and closes at 1:45 p.m. ET.

If it is scrubbed, the next attempt will be Tuesday at 9:32 a.m. ET.

This is the 15th mission for the Falcon 9's first-stage booster B1080. It has had 14 missions before this launch, including a couple of crewed ones:

After the stage separation, the first-stage rocket will land on the A Shortfall of Gravitas that will be in the Atlantic Ocean.

The 21 satellites from the Starlink company, owned by SpaceX, will be heading to low-Earth orbit to join the thousands already there.

And 13 of them have direct to cell capabilities, explained Starlink.

Once deployed and in their orbit, they will provide internet service to many parts of Earth.

Dr. Jonathan McDowell, of Harvard-Smithsonian Center for Astrophysics, has been logging Starlink satellites.
