Live coverage: Ariane 5 blasts off with two Intelsat satellites

SpaceX’s Falcon 9 rocket is set for liftoff from Cape Canaveral on Tuesday, heading due east over the Atlantic Ocean to deliver the GovSat 1 communications satellite into orbit around 32 minutes later.

Ground controllers could try to salvage a Chinese television broadcasting satellite deployed in a lower-than-planned orbit Sunday by a Long March 3B rocket.

An Ariane 5 rocket is counting down to a second launch attempt Saturday to carry two communications satellites into space for DISH Network and Indonesian banking customers, taking the heaviest payload ever launched into geostationary transfer orbit.
