SpaceX launched 21 Starlink internet satellites from Florida's Space Coast early Monday morning (Dec. 23) and landed the returning rocket on a ship at sea.
A Falcon 9 rocket carrying the Starlink spacecraft — 13 of which can beam service directly to cellphones — lifted off from NASA’s Kennedy Space Center in Florida today at 12:35 a.m. EDT (0535 GMT).
The Falcon 9's first stage came back to Earth as planned, touching down in the Atlantic Ocean about eight minutes after launch on the SpaceX droneship "Just Read the Instructions."
It was the 15th liftoff and landing for this particular booster, according to a SpaceX mission description. Eight of those flights have been Starlink missions.
The Falcon 9's upper stage continued hauling the 21 Starlink satellites to low Earth orbit, where they will be deployed about 65 minutes after launch.
