No other planet has made human imaginations work harder than Mars. From ancient Roman times when it was viewed as the God of War because of it's reddish color, to Percival Lowell imagining that he saw canals on Mars, to the first successful Mars flyby pictures where scientists pronounced that it was dry, dusty and lifeless, to the present day - where we have discovered that water once flowed freely across the surface of Mars (and may (?) continue to do so in some places) and the question of life on Mars is wide open!
