A sophisticated communications satellite launches into orbit atop an Atlas 5 rocket Sunday to bring residential high-speed Internet to parts of the U.S. that must look to space for connectivity.

A United Launch Alliance Atlas 5 rocket with a new type of solid rocket booster emerged from its hangar Tuesday evening for the 1,800-foot rollout to pad 41 at Cape Canaveral, moving into position for liftoff Wednesday with a classified National Reconnaissance Office payload.

The experimental recovery of the first stage on an ocean-going barge was not a success.
