How many craters on Mars have ice in them and which ones have permanent ice? I could only find Korolev and the unnamed one - strange for such a remarkable crater. http://www.esa.int/Science_Exploration/Space_Science/Mars_Express/Water_ice_in_crater_at_Martian_north_pole
One would expect all such craters to be famous already.
Which such crater is closet to the equator?
