Live coverage: Intelsat’s first “Epic” satellite in orbit after Ariane 5 launch

SpaceX’s launch team loaded liquid propellants into the company’s first upgraded Falcon 9 Block 5 rocket Friday at the Kennedy Space Center in Florida, and the countdown rehearsal culminated in a brief ignition of the launcher’s nine Merlin main engines on the launch pad.

The first launch of an Italian-made Vega rocket since an in-flight failure nearly one year ago has been postponed to no earlier than Monday night due to unfavorable upper level winds over the Vega launch base in Kourou, French Guiana.

Two communications satellites built in California launched Saturday aboard the third Ariane 5 flight of the year after unacceptable upper level winds kept the rocket grounded Friday. The European rocket lifted off from French Guiana at 2138 GMT (5:38 p.m. EDT) with payloads for DISH Network and BRI, a major Indonesian bank.
