Live coverage: Ariane 5 lifts off with two U.S.-built satellites

A SpaceX Falcon 9 rocket stood atop historic launch pad 39A Saturday afternoon as teams counted down to liftoff with 52 more Starlink internet satellites  and two hitchhiker payloads.

Two direct-to-home broadcasting satellites have launched from French Guiana aboard an Ariane 5 rocket. Liftoff with DirecTV 15 and Sky Mexico 1 occurred at 2116 GMT (5:16 p.m. EDT) Wednesday.

Riding on its side aboard a rail car, a Proton rocket trekked to its launch pad Tuesday at the Baikonur Cosmodrome in Kazakhstan with a Eutelsat television broadcast satellite ready for liftoff Friday.
