Live coverage: Atlas 5 rocket lifts off from Cape Canaveral

The launch of a European Ariane 5 rocket was aborted moments after its main engine ignited Tuesday. The dramatic last-second hold was the first time an Ariane rocket launch was aborted after engine start since March 2011. Arianespace has not set a new target launch date for the mission, which will loft two U.S.-built communications satellites for Intelsat and B-SAT.

An interplanetary space weather station rocketed away from Cape Canaveral aboard a SpaceX Falcon 9 rocket Wednesday, speeding toward a remote operating post a million miles from Earth to help forecasters warn of intense solar storms.
