The white big chunk of rock dubbed Mazatzal turned to a clear ice, once brushed. I guess Sprit wake-up song today is from Vanilla Ice

At NO POINT did I say ANYTHING to flame this guy. I flamed his insane crazy hypothesis - that is all!

It is not possible for solid water ice to exist for long periods of time on the surface of Mars. Have you ever heard of "Sublimation"? It's the process whereby Ice turn directly into water Vapour without ever going through a liquid phase?
At 1% atmospheric pressure, Ice just evaporates into the atmoshere. It doesn't take that long either - you can measure it happening. This is why the Mars Polar Ice caps are covered in Dry Ice. The Dry ice snows or forms via "Hoar Frost" on top of the Water ice layer. This Dry Ice prevents the water ice below from sublimating.
The same process has been seen many times in images of Mars: a very thin layer of water ice frost can form on the surface, and it sublimates as soon as the sun comes up.
Class, this ends the lesson on the difference between correctly agrueing hypothesis and personally attacking an individual while doing so. While I'm at it, I'll second that "STFU Mobius" and add a...Mobius wrote:Now - please do us all a favour - and make your major form of exercise NOT just jumping to conclusions, or making unsubstantiated claims about Mars, and presenting them as facts.
Better yet, if you are so fascinated by Mars, go back to school and learn some physics and some chemistry.
