On Sunday, I posted that the Phoenix probe uncovered a white substance which might be frozen water, though it could have been a salt. Turns out it IS water. The evidence? Some of it disappeared by the time the next picture was taken--it must have evaporated. You can see that white chunks in the Sol 20 picture have disappeared within 4 Martian days. Salt doesn't do that. So Phoenix has found water ice on Mars!
As I said Sunday, this is the first contact with alien water. The probe will now look for evidence of the building blocks for life.
