After the stage separation, the first-stage rocket landed on the droneship A Shortfall of Gravitas in the Atlantic Ocean.
The 29 satellites from the Starlink company, owned by SpaceX, head to low-Earth orbit to join the thousands already there.
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 documenting Starlink satellites.
Before this launch, McDowell recorded the following:
10,939 are in orbit
9,209 are in operational orbit
