Live coverage: Soyuz blasts off on third mission for O3b

The third Ariane 5 flight of the year is on track for a late afternoon liftoff Thursday from French Guiana with two U.S.-built communications satellites to broadcast television channels to millions of DISH Network subscribers and improve banking services across the islands of Indonesia.

After waiting for a Soyuz crew ferry craft to launch and dock, a commercial Cygnus supply ship arrived at the International Space Station with a fresh delivery of more than 5,100 pounds of provisions and experiments Sunday. The rendezvous culminated in the spaceship’s grapple by the space station’s robotic arm at 7:28 a.m. EDT (1128 GMT).

Two European-made communications satellites destined to serve the Brazilian government and commercial customers across Asia are set to ride an Ariane 5 rocket into orbit Thursday.
