Live coverage: Ariane 5 blasts off with two Intelsat satellites

United Launch Alliance called off the planned liftoff of a Delta 4-Heavy rocket and a classified National Reconnaissance Office spy satellite from Vandenberg Air Force Base in California on Wednesday after indications of elevated hydrogen concentrations around one of the launcher’s main engines. Three previous launch attempts were scrubbed by technical concerns and bad weather.

Rocket Lab scrubbed a planned launch from New Zealand Wednesday with 10 small Earth observation satellites for customers in the United States and Japan. Officials have not confirmed a new target launch date for the Electron rocket.
