Live coverage: SpaceX supply ship returns to Earth

The mission marked SpaceX’s second launch of the day. Liftoff happened at 8:47 p.m. PDT (11:47 p.m. EDT, 0347 UTC).

A Russian Soyuz booster arrived at its launch pad on the Kazakh steppe Sunday, the last stop before liftoff Wednesday with a three-person crew bound for the International Space Station.
