Live coverage: Ariane 5 rocket deploys satellites for Australia, India

The first Soyuz launch from Kazakhstan carrying a full load of more than 30 Florida-built satellites for OneWeb’s broadband Internet network has slipped from December to mid-to-late January, OneWeb officials said.

Held down by heavy-duty restraints, a Falcon 9 rocket fired up its nine Merlin engines for more than three seconds Thursday evening in a key readiness test before launching with a commercial television broadcast satellite next week.

Six satellites are set to ride a light-class European Vega rocket into orbit from French Guiana on Wednesday night, the first Vega launch since a failure last year that officials attributed to human error.
