Astrobiologist Dr. Lewis Dartnell talks from the Atacama Desert about a research trip to find extremophiles that might give scientists some clues as to the kind of life that may exist on the surface of Mars. Lewis shows how quartz can act as a natural sunscreen to enable cyanobacteria to grow in the dry desert environment.
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.
