pretty cool! Mars' southpole ice is receding fast. Made me cycle through Sebbie's Mars shots over the past 4 months and read a little on Wiki about seasons in a 25 degree tilt, CO2 dry ice cover subliming within days during spring/summer and exposing water ice, which, when it melts, sublimes as well due to low atmospheric pressure. Very interesting. Thank you!
