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

The Atlas 5 countdown leading up to Friday’s early morning liftoff from Cape Canaveral with Boeing’s Starliner crew capsule will be several hours longer than usual.

SpaceX’s 19th Dragon resupply mission to the International Space Station ended Tuesday with the capsule’s splashdown in the Pacific Ocean southwest of Los Angeles with nearly 3,600 pounds of cargo and experiments.

Space station commander Scott Kelly and Kjell Lindgren carried out a tedious seven-hour 16-minute spacewalk Wednesday, installing cables needed for a new docking mechanism, mounting insulation panels on a physics experiment to improve cooling and lubricating the latching mechanism of the station’s robot arm.
