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

Two NASA astronauts and an Italian flight engineer are sheltering in the space station’s Russian segment as mission control analyzes a possible leak of toxic ammonia coolant aboard the complex.

Three veteran space fliers rode a Soyuz rocket into orbit Wednesday from the Baikonur Cosmodrome in Kazakhstan, heading to the International Space Station for a five-month stay.

The International Space Station cargo ship launching from Cape Canaveral on March 22 has been given a name — the SS Rick Husband.
