Live coverage: Ariane 5 blasts off with two Intelsat satellites

SpaceX’s Falcon 9 rocket is set for liftoff from Cape Canaveral early Thursday, heading due east over the Atlantic Ocean to deliver the Inmarsat 5 F4 communications satellite into orbit 32 minutes later.

SpaceX’s launch director halted a countdown Tuesday to replace a sensor on the upper stage of a Falcon 9 rocket set to blast off with the GovSat 1 communications craft, the product of a joint venture between the commercial satellite operator SES and the government of Luxembourg.

Ten new satellites joined Iridium’s global voice and data relay constellation Sunday after a successful launch, and landing, of a SpaceX Falcon 9 rocket from Vandenberg Air Force Base in California. Liftoff occurred at 1:25 p.m. PDT (4:25 p.m. EDT; 2025 GMT).
