Live coverage: SpaceX Falcon 9 launches

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.

A Falcon 9 rocket is standing on launch pad 39A at NASA’s Kennedy Space Center in Florida for liftoff Thursday to carry the SES 10 communications satellite into orbit on the first mission SpaceX has attempted to re-fly one of its used boosters.

An Ariane 5 rocket launched Tuesday with the Arabsat 6B and GSAT 15 communications satellites to broadcast television across the Middle East, North Africa and Central Asia and link India with telecom and navigation services. Liftoff from Kourou, French Guiana, occurred at 2134 GMT (4:34 p.m. EST).
