Ice on Mars!!

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.
