Live coverage: Ariane 5 blasts off with two Intelsat satellites

A United Launch Alliance Atlas 5 rocket departed Cape Canaveral at 11:36 a.m. EDT (1536 GMT) to deploy the Global Positioning System 2F-10 navigation satellite.

SpaceX rolled a Falcon Heavy rocket back to its launch pad in Florida Tuesday night for liftoff Thursday with a high-power Viasat broadband satellite, following an eight-day delay for a launch vehicle engine swap.

The mission represents the fifth pair of Boeing-built O3b mPOWER satellites to launch into medium Earth orbit. The Falcon 9 rocket lifted off from pad 40 at Cape Canaveral Space Force Station on Tuesday, July 22, at 5:12 p.m. EDT (2112 UTC).
