Live coverage: SpaceX launches another batch of Starlink satellites

China launched a Long March 2C rocket Friday with three Yaogan 30 military satellites, and tested new grid fins on the Long March’s first stage to help guide the spent booster away from populated areas.

A Falcon 9 rocket launching an Argentine Earth-observing satellite streaked across the skies of Southern California on Sunday night, then its booster stage returned to Vandenberg Air Force Base for an on-target landing, the first by SpaceX on the West Coast.

United Launch Alliance kicked off its 2018 launch campaign with a Delta 4 rocket flight at 2:11 p.m. PST (5:11 p.m. EST; 2211 GMT) Friday from Vandenberg Air Force Base in California. Gusty winds forced officials to call off a launch attempt Wednesday, and technical problems halted a countdown Thursday multiple times. The Delta 4 launched with a top secret spy satellite for the National Reconnaissance Office.
