I can't see an NHL expansion team on Mars, but I could see the KHL moving their operations there for a more favorable Martian exchange rate. Plus many of the players would be used to the conditions similar to Siberia.
I can see some of the single KHL players making the move to Mars. The married ones, not so much. Mars ain't the kind of place to raise your kids. In fact, it's cold as hell.
