Just finished watching two hours of Mars television on National Geographic. Interesting that the Mars images no longer show a red surface and pink skies. Chalk one up for the woo-woo’s.
The most interesting thing out of the Phoenix team is that perchlorate can reduce the freezing point of water to -70. They did not assign C or F. That makes this image a little more interesting. Water, perchlorate, temps above -70 in sunshine. Not only does it look like a damp spot, it most likely is.
