Mars Life?

Can't definitively say anything yet, but this is the most promising indication of extraterresial life humans have found beyond Earth. To me it sure looks like the splotches lichens leave on rocks, but non living chemical origins have not been ruled out. Even if it is proof of ancient Mars life I suppose there is still the possibility that it originated on Earth and was projected over to Mars by an asteroid impact or some other exchange in the early solar system. Either way, scientists would Love to have this sample in an Earth based lab to do more extensive analysis. And as Edgar Mitchell,6th man to walk on the moon said in 1974: "You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do somethong about it. From out there on the moon, international politics look so petty. You want to grab a politician by the scruff of the neck and drag him a quater of a million miles out and say, "Look at that,you son of a bitch."
