The six volunteers were to emerge from isolation on November 4, 2011 after spending almost one-and-a-half-years locked away from the world at a Russian research centre to test the effects on humans of a flight to Mars. The unprecedented experiment has simulated the duration and isolation of a return journey to the Red Planet, even including "walks" on a replica of the Martian surface and 20-minute time gaps in communication with outside.
