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.

With Hurricane Isaias threatening Florida’s East Coast, astronauts Doug Hurley and Bob Behnken are awaiting a go-ahead on plans to undock from the International Space Station Saturday, setting up a fiery plunge to splashdown Sunday, presumably in the Gulf of Mexico, to close out a 64-day flight.

A commercial Cygnus supply ship departed the International Space Station on Friday for an extended mission to deploy five nanosatellites and conduct other experiments before re-entering the atmosphere and burning up with more than two tons of trash.
