How do you thaw US-Russia relations? Launch them into the frozen depths of space

Scott Kelly and Mikhail Kornienko will spend a year together on the International Space Station and conduct research into the feasibility of a manned Mars mission

Their respective countries may be going through one of the worst periods of hostility since the end of the cold war, but this week an American astronaut and a Russian cosmonaut will fly up to the International Space Station to spend a year on board together.

Despite the enmities of the cold war and the frigid relations of their governments today, scientists and astronauts from Nasa and its Russian equivalent, Roscosmos, have a fruitful and friendly history of recent cooperation. As the US government has cut space program funding, for instance, Nasa has turned to its Russian counterpart to assist with mission logistics such as sharing a launch pad.
