A British man is hoping to set a new world endurance record by living solo for 60 days on a remote island rock, to raise money for charity.
Rockall is a 21m high eroded volcano, lying 260 miles from the Outer Hebrides, in the North Atlantic.
Nick Hancock will stay in a pod on the rock, to protect him from the elements.
