Liftoff took place 10:43 a.m. EST (1543 GMT; 7:43 a.m. local California time) after being delayed from Jan. 15.
SpaceX just launched its first Starlink mission of the year.
SpaceX brought another big batch of its Starlink internet satellites to orbit on Thursday (Jan. 19), and landed a fresh first stage of its Falcon 9 rocket as well.
The booster topped with 51 of SpaceX’s Starlink internet satellites lifted off from California’s Vandenberg Space Force Base on Thursday at 10:43 a.m. EST (1543 GMT; 7:43 a.m. local California time).
The launch was originally targeted for Jan. 9, but SpaceX stood down from that attempt due to bad weather. The company also scrubbed a potential try on Jan. 10 to take more time to examine data from the Falcon 9’s upper stage. SpaceX then targeted Sunday (Jan. 15) but changed that plan to Jan. 18 due to bad weather. The target date then slipped again, to Thursday.

The Falcon 9’s upper stage, meanwhile, hauled the Starlink satellites to low Earth orbit and was expected to deploy all 51 of them 29 minutes after liftoff, according to a SpaceX mission description.

Starlink is SpaceX’s broadband internet constellation, which currently consists of more than 3,300 operational satellites.
That number is ever-increasing, as Thursday’s liftoff shows, and may eventually become truly staggering. SpaceX has approval to launch 12,000 Starlink spacecraft and has applied for permission to loft nearly 30,000 more on top of that.
