Live coverage: Proton launch runs into trouble

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.

The second of three robotic resupply ships going to the International Space Station in two weeks has arrived at its launch pad in Kazakhstan for liftoff Thursday aboard a Soyuz rocket.

SpaceX rolled a Falcon Heavy rocket back to its launch pad in Florida Tuesday night for liftoff Thursday with a high-power Viasat broadband satellite, following an eight-day delay for a launch vehicle engine swap.
