Live coverage: Ariane 5 blasts off with two Intelsat satellites

SpaceX’s Falcon 9 rocket is set for liftoff from Cape Canaveral early Friday, heading due east over the Atlantic Ocean to deliver the JCSAT 14 communications satellite into orbit 32 minutes later.

Europe’s fifth Sentinel Earth observation satellite will ride a four-stage Vega rocket into polar orbit 488 miles above Earth to begin tracking changes in agriculture and forestry patterns and monitoring natural disasters.

A SpaceX Falcon 9 rocket, built with extended propellant tanks and engines rated for higher thrust, is poised for liftoff on the company’s first launch since a catastrophic failure in June grounded the commercial booster.
