Does mars have polar ice caps?

Sort of, depending on who is talking...

As seen through a modestly good telescope, the poles show white caps that grow and shrink with the seasons. They are not solid caps of ice, metres or even kilometres thick, such as we have on Earth, but just a thin frost of carbon dioxide crystals ("dry ice") and water crystals (snow or hoar frost) mainly on the ground surface. There is more material underground, but not very much and not visible from off the planet.

If that is what you are willing to call a planetary ice cap, then the answer is yes.

If not, then bad luck! No!
