SpaceX launched another batch of its Starlink internet satellites from Florida's Space Coast today (Jan. 27).
A Falcon 9 rocket carrying 21 Starlink spacecraft, including 13 with direct-to-cellphone capability, lifted off from Cape Canaveral Space Force Station today at 5:05 p.m. EST (2205 GMT).
The Falcon 9's first stage returned to Earth about eight minutes after liftoff as planned, touching down in the Atlantic Ocean on the SpaceX drone ship "A Shortfall of Gravitas."
Today's flight was the 20th launch and landing for this particular booster, according to a SpaceX mission description. Eleven of its 20 flights have been Starlink missions.
The Falcon 9's upper stage, meanwhile, continued carrying the 21 Starlink satellites to low Earth orbit. It will deploy them there about 65 minutes after liftoff.
