SpaceX launched another big batch of its Starlink internet satellites to orbit early Monday morning (June 12) and landed the returning rocket at sea.
A Falcon 9 rocket topped with 52 Starlink spacecraft lifted off Monday at 3:10 a.m. EDT (0710 GMT) from Cape Canaveral Space Force Station in Florida, in the first of two planned SpaceX launches for the day.
The Falcon 9's first stage returned to Earth about 8.5 minutes after liftoff for a pinpoint touchdown on the SpaceX droneship A Shortfall of Gravitas, which was stationed in the Atlantic Ocean.
It was the ninth launch and landing for this particular booster, SpaceX wrote in a mission description.
The rocket's upper stage, meanwhile, will continue carrying the 52 Starlink satellites to low Earth orbit, ultimately deploying them there about 65 minutes after liftoff.
SpaceX has launched more than 4,500 Starlink satellites to date, and nearly 4,200 of them are currently operational, according to astrophysicist and satellite tracker Jonathan McDowell.
But the Starlink megaconstellation is nowhere near complete: SpaceX has permission to deploy 12,000 of the broadband satellites and has applied for approval for another 30,000 on top of that.
The early-morning Starlink liftoff was the first leg of a planned Falcon 9 doubleheader on Monday. SpaceX also plans to launch the Transporter-8 rideshare mission at 5:19 p.m. EDT (2119 GMT) from Vandenberg Space Force Base in California. Transporter 8 will send 72 satellites aloft for a variety of customers.
