All newspapers today give this beautiful news: There is ice on Mars and this was the results of analysis by NASA Phoenix Mars Lander.

I have read this article from New York Times and I think next step would be the search for life, very elementary life. Indeed, looking at pictures from Mars it does not come as a surprise that water existed in liquid form on the planet time ago and Mars should have had a very different aspect. But it is also possible that life existed at that time and now it is completely disappeared. There has been a temporal window inside which some kind of evolution took place but all depends on the width of the window to define the complexity of such organisms. Anyhow, having such a large reservoir of water should make a manned mission on Mars easier in the future.
Due to the large success and to a wide availability of resources, NASA planned to extend this mission further. Please, folks do not give up the good work!
