Live coverage: Ariane 5 blasts off with two Intelsat satellites

A new Chinese mobile communications satellite launched Thursday on top of a Long March 3B rocket, joining a similar spacecraft launched four years ago to provide voice and data services to users on the go.

The United Launch Alliance Atlas 5 rocket with the Air Force’s X-37B spaceplane lifts off at 11:05 a.m. EDT from Complex 41 at Cape Canaveral Air Force Station in Florida.

The launch of a commercial Bulgarian television broadcast satellite from NASA’s Kennedy Space Center in Florida is set for Monday after SpaceX ran through a mock countdown Thursday and test-fired a previously-flown Falcon 9 rocket’s Merlin main engines.
