Russian-U.S. crew arrives safely at the International Space Station for the start of a ground-breaking year-long stay. Paul Chapman reports.
This was the moment a Soyuz capsule carrying two Russian cosmonauts and an American astronaut arrived for the latest mission at the International Space Station. The mission for two of them - Scott Kelly and Mikhail Kornienko - is to stay for a whole year. It's a first for the ISS where missions until now have been about half that. Scientists are trying to find out how the human body fares during longer stays in space. It's the first time anyone's spent a year on the ISS although four Soviet-era cosmonauts did that and more aboard the Mir space station. Kelly's identical twin brother, a former NASA astronaut, is serving as the ground-based subject. The third crew member on this trip will return to Earth in September but not without setting a new record himself. Gennady Padalka will have racked up 878 days in space by then...the longest total time anyone's ever achieved.
