Well, we've beat that horse regarding water-ice clouds in the sky...
...However, just as interesting (and some may say more interesting) is the possibility that the area in which Curiosity is now sitting could have once
been a relatively deep water lake.
Much of the low-lying floor of Gale Crater may have been the bed of an ancient Martian lake a couple of billion years ago -- although much of the lake
bed may have been covered up by blowing dust after the lake dried up. However, but there are exposed areas of strata on the sides of Mt. Sharp (the
mountain inside the crater) that could have been formed by muddy sediment being laid down inside the lake. NASA hopes to investigate these strata,
and perhaps find layers that existed during the time Gale Crater was still a lake.
There are also alluvial fans to the North of the site, which also looks to have been laid down by running water. Those alluvial fans could be the
remnants of localized flooding, and the investigation of that sediment could be quite exciting.
This is a great landing site, with the potential for some interesting discoveries.
