It is pretty well known fact that there is water on Mars. What is new is this picture taken by ESA's (European Space Association) Mars Express Spacecraft. This is the clearest ever picture of water ice on Mars. It seems the Ice will be there all round the year as the temperature/pressure in that part of the planet does not allow it to condense and evaporate.
