Presentations from the First Mars Express conference held in February
are available here:

First Mars Express Conference Presentations.

These reports are longer than the 2-page abstracts seen from the Lunar
and Planetary Science Conference, some over 30 pages long.

A great image of dense fog in Valles Marineris is shown in this
report:

And this report has a beautiful full-color image of this very dense
fog:

Adsorption water driven processes on Mars.

This article speculates on how adsorbed layers of water might be used
by microbes on Mars.

Valles Marineris is both low altitude and low latitude so should be
within the pressure and temperature range to permit liquid water for
this fog close to the surface.

Here is the full-color image from Mars Express of the dense fogs over Marineris:

These are clear images of the Martain fog. It would appear that we are almost on the surface. To all those who have made this possible may we
thank them with: Good Job! Well Done! Such a magnificent accomplishment!!!

Wow, that is some really thick fog. I didn't think there was enough moisture in the atmosphere to allow fog? I thought there was just the odd small cloud.

I don't know if there is any micobial life on mars... but with fog like that, I am sure we could engineer something.
