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

A new satellite joined Russia’s Glonass navigation fleet Saturday with a successful launch on top of a Soyuz rocket into an orbit nearly 12,000 miles above Earth.

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.

One day after a Soyuz crew transport rolled out to a launch pad at the Baikonur Cosmodrome in Kazakhstan, a similar Russian booster made a comparable journey Monday halfway around the world in tropical French Guiana for liftoff Thursday with two European Galileo navigation satellites.
