Video: Soyuz MS-01 leaves the space station for landing

United Launch Alliance teams ran through an 11-hour countdown Friday at Cape Canaveral to rehearse procedures before the first flight of a modified Atlas 5 rocket with Boeing’s Starliner crew capsule Dec. 20.

SpaceX test-fired a Falcon 9 rocket Saturday at Cape Canaveral, a critical test before liftoff Wednesday with several tons of cargo heading to the International Space Station.

The launch of a Russian Progress cargo ship aboard a Soyuz rocket was aborted in the final minute of the countdown Sunday, forcing a delay of at least two days in the start of a resupply and refueling mission to the International Space Station.
