CAPE CANAVERAL SPACE FORCE STATION — Despite pushing the launch time back, SpaceX was able to launch more than 20 Starlink satellites under good weather on Monday evening.  

The Falcon 9 rocket sent up Starlink 12-7 mission from Space Launch Complex 40 at Cape Canaveral Space Force Station, stated SpaceX. 

The launch window originally was set to open at 3:22 p.m. ET, but was pushed back to 5:05 p.m. ET. The window was set to close at 6:21 p.m. ET.

The 45th Weather Squadron gave a 95% chance of good liftoff conditions, with the only concerns being the cumulus cloud rule. .

About the mission

The 21 satellites, including 13 that have direct-to-cell service, are from the Starlink company. They will be going to low-Earth orbit.

SpaceX owns the Starlink company.

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

Harvard-Smithsonian Center for Astrophysics’ Dr. Jonathan McDowell keeps track of Starlink satellites.

Before this launch, McDowell recorded the following:

• 6,982 are in orbit
• 6,243 are in operational orbit
