Live coverage: Ariane 5 lifts off on its first Galileo launch

Launching with a Spanish radar observation craft and the first two experimental satellites for SpaceX’s planned global broadband network, a Falcon 9 rocket fired away from California’s Central Coast shortly before sunrise Thursday after several days of delays.

An Ariane 5 rocket launched from French Guiana at 2150 GMT (5:50 p.m. EDT) Thursday with a pair of European-built communications satellites for the Brazilian government and KTsat, a South Korean telecom operator. Liftoff was delayed more than one hour to resolve a problem with ground equipment.

The U.S. military’s next GPS navigation satellite was ready for launch from Cape Canaveral at 9:43 p.m. EDT Friday (0143 GMT Saturday) aboard a SpaceX Falcon 9 rocket. But SpaceX aborted the countdown just two seconds prior to liftoff.
