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

NASA astronaut Mark Vande Hei and two cosmonauts blasted off from Kazakhstan Friday and docked with the International Space Station after a two-orbit chase, the first step in a record crew rotation requiring two launches and two landings with four different spacecraft in just three weeks.

A Russian satellite reportedly designed to track enemy submarines and a spacecraft to help calibrate ground-based military radars lifted off Saturday aboard a modified Soyuz rocket, but one of the payloads apparently failed to deploy from the launcher’s upper stage, according to Russian media.

Ground teams at the Kennedy Space Center were packing last-minute cargo into a commercial Dragon supply ship Sunday, a day before the automated freighter is set for liftoff on top of a SpaceX Falcon 9 rocket on a two-day trek to the International Space Station.
