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?

    $\begingroup$ Looking at Google Mars, there appears to be a smaller one a bit closer to the equator. $\endgroup$ – Keith McClary Aug 2 at 3:42

  • $\begingroup$ The answer completely depends on what how you define your terms. Do you count craters on the ice caps? What season on Mars, given that the ice caps grow and retreat and frost can form in craters as close to the equator as 45° latitude? What is the minimum size you are interested in? Do you only count large ice deposits, or as I mentioned, the seasonal frost? Korolev is certainly one that lots of people point to as a type example, but I'm a fan of McMurdo (en.wikipedia.org/wiki/McMurdo_(crater)) which has a lot of seasonal frost and is within the seasonal (but not permanent) cap. $\endgroup$ – Stuart Robbins Aug 3 at 3:27
