Arianespace’s 2009 mission rate is being continuing apace as three Ariane 5 vehicles are now in the workflow for launches from French Guiana. One Ariane 5 rolled out today for liftoff with the JCSAT-12 and Optus D3 telecom satellites tomorrow night, while another launcher is ready for its move into the Spaceport’s Final Assembly Building. The third Ariane 5 arrived this week in French Guiana aboard a sea-going transport ship and will soon begin its build-up.
