Live coverage: SpaceX launches first Falcon 9 mission of the year

Churning out the launches at a rapid pace, the Atlas 5 program sent another rocket soaring like clockwork Thursday for deployment of a national security satellite duo from California.

SpaceX scrubbed the planned launch of its next set of Starlink satellites Friday. A Falcon 9 rocket is awaiting liftoff from pad 39A at the Kennedy Space Center in Florida with 57 Starlink Internet satellites and two commercial Earth-imaging microsatellites for BlackSky.

Launching the commercial WorldView 4 Earth-imaging satellite for DigitalGlobe, a United Launch Alliance Atlas 5 rocket thunders away from California’s Vandenberg Air Force Base today at 10:30 a.m. local time (1:30 p.m. EST; 1830 GMT).
