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

Taking off and landing in the middle of the night at Cape Canaveral, a SpaceX Falcon 9 rocket successfully delivered a Dragon supply ship to orbit for the International Space Station as the launcher’s first stage booster swooped to a spectacular touchdown.

Russian officials could complete their investigation of a rocket failure Tuesday by mid-December, and multiple Russian news reports suggest the probe has narrowed to focus on the guidance computer on the Soyuz launcher’s Fregat upper stage.

A Russian Progress resupply and refueling craft launched Monday from the Baikonur Cosmodrome in Kazakhstan, riding a Soyuz booster into orbit on a perfectly-timed departure that set the stage for an on-target docking with the International Space Station less than four hours later.
