There are so many oddities of these impact "ejecta blankets" that I tend to think additionally of caldera "effusive blankets". These are the heady days of data collection; we still need to sit back and model processes.

Hot from LPSC - we were shown a well-exposed image of the large bright spot in Occator. It has central fractured dome surrounded by a shallow discontinuous 'moat' and slightly elevated outer parts. It is bright, but not ice, so some kind of salt or bright mineral.

I expect there will be a release soon, as it has now been shown.

Among today's image release is a large mosaic of Occator crater showing exquisite detail.

So, basically, there's a bright white mountain in the centre of the crater. I'd like to get an oblique view of that..

I am also reminded of Enceladus, though it was the similarity of the central dome to craters like that that struck me.

Haven't used this process for a while but here is a blink animation I did a long while back for sub-pixeling an image of Occator in Survey Orbit.

The image is blinking between the original cropped view from Survey Orbit #16, the sub-pixeling version and finally Occator in LAMO. The final LAMO image has been skewed because the original image of SO was somewhat oblique in view.

I'm rather intrigured so many details seem to remain consistent while others seem present but shifted due to the nature of the original low resolution.

The spots a fumaroles, unremarkable except for their size and presumably duration of activity. Even then, the whole Occator region is remarkable.

Looks almost like lava/mud flow at the edges of the PIA20350 where it appears to have pooled up and cooled as the level raised against the terrain barrier, forming the raised edge at the pool boundaries.

Also dont miss the enhanced color version.

Wonderful, and finally, Occator in exquisite detail. To backtrack a bit, the impact hypothesis is out, and the idea of water ice seem less likely now.
So salt is the winner, salts that have built up around fumaroles that carry salty water from the interior or Ceres.
Several images including one in colour linked from this page. smile.gif

here is a blink animation

Thank you. It highlights for me that there seems to be a 'bright spot within the bright spot', quite small, in the extended filigree at around 10-o'clock.

A very fresh salt patch? Brightly-lit sports arena?
