Live coverage: Ariane 5 blasts off with two Intelsat satellites

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.

Russian rocket technicians working in the French Guiana jungle transported a three-stage Soyuz booster to its launch pad Monday and erected it upright for liftoff Thursday with four communications satellites for O3b Networks.

A military communications satellite, built with international funding from Canada, Denmark, the Netherlands, Luxembourg and New Zealand, has been stacked atop a Delta 4 rocket to launch into a worldwide information-relay network operated by the U.S.
