Dr Claire Cousins and Mark Fox-Powell explain how scientists look at life that exists in extreme environments on Earth, to see what kind of life scientists might see on the surface of Mars. This knowledge helps scientists plan the best target for a rover.
Professor Cockell takes us through the astrobiology labs at Edinburgh University, where scientists recreate analogues of ancient Martian environments.
This video is part of a series of ten which look at the one of the elements of the European Space Agency’s Aurora programme – Europe’s journey to Mars.
