...or at least those on Monday -- which is to say most of the important ones, dealing specifically with the latest results from ER and Mars Express. I've gotten another assignment from "Astronomy" to do a one-page piece on each of those subjects. (I would have loved to hang around for the remainder of the meeting to cover the Saturn and Titan meetings in particular -- but, alas I wasn't offered enough to even cover my motel expenses for that, since those meetings are spread across three more days. I do, however, intend to take careful note of the Saturn and Titan posters available on the first day.)

It's awfully late for me to give you this news -- but does anyone have any particular questions you'd like me to look into while I'm there?

Those images have had strong contrast enhancement, but the Noctis Labrynthus clouds Viking imaged are fairly opaque. I do not see resemblence to cumulus, there's no relief on the cloud's and they are not sharp edged. Rather, they appear to be unusually dense ice-fog. Note that Labrynthus Noctis is at such high altitude, the valley floors are at lower pressure than the triple point of water and liquid is not stable at any time.

I've been frustrated that the only version of these images is the NASA press release with terrible uncorrected color shading caused by bad early-mission orbiter camera calibration files. They were never reprocessed into high quality images.
