Eight more satellites for Europe’s Galileo navigation fleet will be built by Germany’s OHB System AG and Britain’s Surrey Satellite Technology Ltd. under a contract worth more than $350 million.

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.

SpaceX has delayed the launch of the SES 12 commercial communications satellite from Cape Canaveral until Monday to conduct additional tests on the Falcon 9 rocket’s second stage, officials said Thursday.
