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

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.

Three new space station residents blasted off Wednesday on a fast-track six-hour pursuit of the orbiting research complex, kicking off five months in space. The U.S.-Russian-Japanese space crew lifted off at 2102 GMT (5:02 p.m. EDT) from the Baikonur Cosmodrome in Kazakhstan, and docking occurred 0245 GMT (10:45 p.m. EDT).

Japan’s fifth HTV cargo freighter completed a five-day flight to the International Space Station on Monday, making a glacial laser-guided approach to the complex with a 9,500-pound package of food, spare parts and experiments.
