Antarctica to Mars: The loneliest job in the world BBC

Mars is once again in the spotlight after Nasa successfully landed its biggest ever robot on the Red Planet – an achievement that naturally raises the question of when man will first set foot on the red Planet. Already, researchers are hard at work trying to understand what it would take to succeed in such a mission. One of those is Dr Alexander Kumar, based at the Concordia research station in the centre of Antarctica, a place so remote – and so cold – that it is only possible to get in and out for three months of the year.
He is trying to understand the physical and psychological effects of human space travel, particularly the role of extreme isolation. BBC Future spoke to Dr Kumar about life at the station and how his stay may be the fore runner for a manned mission to the red Planet.
