Live coverage: Ariane 5 successful in middle-of-the-night launch

Elon Musk, SpaceX’s founder and chief executive, spoke with reporters via conference call May 15 as the company prepared for the launch of the first 60 satellites to build out a network of potentially thousands of broadband relay stations in low Earth orbit providing high-speed Internet to consumers around the world.

Inverted cables on the Vega rocket’s upper stage control system apparently caused the launcher to tumble minutes after liftoff Monday night, a failure that resulted in the loss of a Spanish Earth observation satellite and a French research probe, Arianespace officials said Tuesday.

The 13th and 14th operational members of Europe’s Galileo navigation satellite network are set for liftoff Tuesday aboard a Soyuz rocket from French Guiana. Track the progress of the flight with this timeline of key events.
