This one is part of a campaign to monitor changes in the south polar cap as the season advances toward summer:

It's the first southern polar cap image I've seen from HiRISE - and whilst I've not looked too closely, I don't think I can find it in any MOC images either.

That's what I thought. Maybe this is the first in the campaign. Or maybe they're sitting on something.

It is only just now entering the season that we can take south pole pictures. I think it's been maybe a few weeks, not much more than that. So by the time our cycle has been able to be released, it's the first image of a series. I think it's just barely entering Martian Summer spring, so... |

I'm not exactly sure what I'm seeing in this image, but I'll take a stab at it. At full resolution, the main part of the light-toned unit has tons of cracks. To me, it looks an awful lot like the light-toned outcrop that Opportunity has been investigating at Meridiani Planum. However, his light-toned unit in Aram Chaos, however does not display a sulfate signature in OMEGA spectra. Now, the OMEGA team uses the presence or absence of three features related to bound water in minerals to identify sulfates and other hydrous minerals. I think it is possible that those cracks that we see in the HiRISE image are dessication cracks--meaning that this unit was once hydrated, but somehow the water was lost, and thus volume was lost, leading to the fracturing. If the light-toned unit no longer contains water, then OMEGA can't identify it as being sulfate-rich.
I don't know if any of this is right, but it seems to at least be plausible. |
