PARIS — Satellite fleet operator SES, which this year has suffered both predictable satellite-launch delays and unpredictable satellite failures, on Aug. 28 said it would move a satellite from launch-service provider SpaceX to Arianespace to minimize revenue losses.

As a result, the SES-14 satellite will launch aboard an Ariane 5 ECA rocket early in Q1 of next year rather than a less-clear Q1 launch date offered by SpaceX. SpaceX instead will launch the heavier SES-12 satellite, up to now slated for an Ariane 5, on a Falcon 9 vehicle . . .
