Dfrank, when you return, there's something that you should know that puts a hole in your idea about that image.

Quote:
Although the temperature on Mars can reach above 273K (0°C), liquid water is unstable as the atmospheric pressure is below water's triple point and water ice simply sublimes into water vapour.
Now, some hope does exist.

Quote:
An exception to this is in the Hellas Planitia impact crater, the largest such crater on Mars. It is so deep that the atmospheric pressure at the bottom reaches 11.55 millibars, which is above the triple point, so if the temperature exceeded 0°C liquid water could exist there.
However, as the Mars rovers aren't in that area, then your opinion on this image does not stand up to scientific fact.
