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

Russia launched an early warning satellite Tuesday, deploying the first in a new fleet of military satellites to detect missile launches heading for Russian territory.

A Russian Soyuz booster climbed into orbit Monday with a U.S. Army colonel, a veteran Russian cosmonaut and a Canadian flight engineer, kicking off a six-hour chase of the International Space Station.

With plans for the first all-female spacewalk derailed by suit sizing issues, astronauts Christina Koch and Nick Hague floated outside the International Space Station Friday for a revised excursion to help fix a solar array battery problem and to connect a second set of replacement batteries as originally planned.
