As a human species, all of us have thought of the same idea: "Is there life on other planets?" We also know that to have life there has to be water on that planet. On May 21st, 2011 Roger Phillips, a man from the Southwest Research Institute in Border, Colorado believe that they have found a new reservoir of dry ice on Mars! Phillips says that this is very intriuging since Mars tilts on his axis about every 100,000 years. Since this occurs the frozen carbon dioxide on the planet is released. The more carbon dioxide there is in the atmosphere means the more chance of liquid water on that planet. So dry ice is very rare on Mars now, which with this discovery is arising questions about Mars. Therefore this discovery is very rare nowadays.
