Live coverage: SpaceX Falcon 9 launches

The Starlink 17-30 mission sent the batch of satellites into a polar low Earth orbit. Liftoff of the Falcon 9 rocket from pad 4E at Vandenberg Space Force Base happened at 9:47:29 p.m. PST (12:47:29 a.m. EST / 0547:29 UTC).

Resembling a cocooned insect with antennas and appendages tucked snuggly to its body for launch, NASA’s latest communications relay hub will be shot into space Friday to blossom in geosynchronous orbit for routing signals to and from the International Space Station, the Hubble Space Telescope and three dozen science observatories.

A Northrop Grumman Cygnus supply ship carrying more than 7,200 pounds of provisions and experiments approached the International Space Station two days after its launch from Virginia, moving close enough for capture by the station’s robotic arm at 5:28 a.m. EST (1028 GMT) Monday.
