Live coverage: Ariane 5 rocket launches TV broadcast satellites

Monday night’s blastoff of a Vega rocket from the northern shore of South America dispatched a 2,500-pound Earth imaging satellite for Europe and put on a light show across the tropical spaceport at the edge of the Amazon.

In one of the strongest public endorsements of SpaceX’s initiative to put a reusable launcher on the commercial market, a top official from satellite communications giant SES said Tuesday that the company wants to fly one of its pricey payloads on a used Falcon 9 rocket, perhaps even without a test flight.

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.
