Live coverage: Two satellites lift off aboard Ariane 5

The launch an Ariane 5 rocket with Brazilian and Korean communications satellites that was set for this week has been postponed indefinitely after protesters blocked access to the French Guiana spaceport.

Arianespace’s launch team in French Guiana rolled an Ariane 5 booster to its launch pad Tuesday and readied the rocket for liftoff Wednesday with an Inmarsat satellite to connect airline passengers over Europe and an Indian communications craft.

Putting new technology in the sky that will beam high-speed Internet to rural America, a United Launch Alliance Atlas 5 rocket lifted off from Cape Canaveral today to deploy the commercial EchoStar 19 satellite. Follow the ascent in our live journal.
