Live coverage: Ariane 5 launch aborted
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.
