Live coverage: Ariane 5 blasts off with two Intelsat satellites

A Boeing Starliner crew capsule fired off a stand early Monday at White Sands Missile Range in New Mexico on a mile-high test flight to validate the spacecraft’s emergency escape thrusters. Only two of the ship’s three main parachutes deployed on descent, but Boeing officials do not expect any impacts on the planned launch of an unpiloted Starliner demonstration mission to the International Space Station in December.

Flying through the sky at supersonic speed, a Falcon 9 rocket stage descended to a historic landing at Cape Canaveral on Monday, returning to the spaceport minutes after boosting 11 Orbcomm communications satellites toward orbit on SpaceX’s first mission since a major failure in June.

The forecast of stormy weather prevented rollback of the mobile service gantry and the continuation of the countdown at Cape Canaveral on Wednesday for the United Launch Alliance Delta 4 rocket.
