Live coverage: Soyuz crew arrives at International Space Station

A SpaceX Falcon 9 rocket lifted off from Vandenberg Space Force Base in California at 12:26 p.m. PDT (3:26 p.m. EDT; 1926 GMT) Friday with another batch of 52 Starlink internet satellites. The mission is the first of two SpaceX launches scheduled Friday, with another Falcon 9 poised for liftoff from Florida a little more than four hours later.

SpaceX conducted the first hold-down firing of an upgraded version of the Falcon 9 rocket Friday at NASA’s Kennedy Space Center in Florida, in preparation for launch next week with Bangladesh’s first communications satellite.

An electrical problem on SpaceX’s drone ship parked just off the coast of Cape Canaveral prompted SpaceX to scrub a Falcon 9 launch attempt early Friday, delaying the start of a resupply mission to the International Space Station by 24 hours.
