Live coverage: Two satellites lift off aboard Ariane 5

An electrical problem on one of the Ariane 5 rocket’s two solid rocket boosters led to an on-pad launch abort Tuesday, likely delaying liftoff with two U.S.-built communications satellites until around the end of September, Arianespace officials said.

Arianespace plans 11 launches from French Guiana this year, including eight flights by the heavy-lift Ariane 5 rocket with up to a dozen large telecommunications satellites and four spacecraft for Europe’s Galileo navigation system.

A late-night liftoff Thursday lit up the forested shoreline of South America as a Russian-made Soyuz rocket streaked into orbit with two new satellites for Europe’s Galileo navigation system. Relive the launch with a video replay and photos of the fiery departure.
