I thought the Martian Polar ice caps were frozen CO2 ? It also "melts".
Maybe there is something in the article that explains this.
I think NASA wants it to be ice. it's much more exciting, and congress is much more likely to fund ice than frozen CO2.
yes they do. its kinda funny as I recall an article a few days ago that seemed to indicate that the ice they suspected was there could not be found. and then this story happened.
I hope its ice, that means possible life which explains the little green men I have chained up in the garage.
