Not likely. Won't visit for another year and the sun angle will no longer light up the south pole--See Carolyn Porco's Blog. View should get good again starting in 2025. blink.gif

VP Thanks for the great mosaic!!! Get some sleep now.

Interesting that jet VII is the only one not issuing from the heart of a sulcus itself. What might that say about the processes at work here, if anything?

Beautiful work, Jason; thanks very much! smile.gif

I'm still amazed at how rough this terrain is at this scale.

It could simply be that the predicted source location of VII was a bit off the mark. Projecting the jet sources back to the surface is no simple task!

Great mission and work Carolyn and Jason--but now that you have had two days of exclusive play--how about releasing the raw images for others to play with. cool.gif

Don't thank me so much as Paul Helfenstein, who did a great job once again targeting these images even as we were flying by so quickly. Some of the images were even off a bit from where he targeted, and they were even better.

Way to go, Paul! Awesomeness.

Thanks for the mosaic, Vikingmars, that's helpful.

I've been spending the morning trying to figure out where all the skeet shoot footprints fell, because they didn't quite match the preview map. Here's what I came up with. Yellow footprints are rev 91 (Oct 31); green footprints are rev 80 (August). Red dots are the plume sources. Numbers refer to the image source -- PIA images have been released on Photojournal, the N00 and W00 numbers are available as raws. There's the makings of a pretty fine high-res mosaic covering parts of Baghdad, Cairo, and Alexandria sulci, but I don't think I have the patience to attempt to assemble it.

Emily, for the sake of completeness, could the locations of PIA06252 and PIA06251 be added to your composite?

They could, if I had a clue where they fell. The WAC image in that pair (PIA06251) has a resolution of 37 meters per pixel, so its footprint should be similar in size to Skeet Shoot #9 from Rev 91. However, it was from much earlier in the season, when much more of the south pole was sunlit -- it's totally possible that it could fall in a dark area. Does anybody have any better information on where that fell? It should be in the metadata on the PDS but I don't have time at the moment to track it down.

The dark blue outlines represent the location of the Rev11 hires shots. The outer dark blue outline is PIA06251 and the inner dark blue outline is PIA06252. BTW, Emily, the sulci labels are not quite right. The fracture labeled "Damascus" is unnamed, "Baghdad" is Damascus, "Cairo" is Baghdad, "Alexandria" is Cairo, and Alexandria is in the shot.

The actual Rev91 Skeet Shoot footprints are now posted on the CICLOPS site:

And I echo volcanopele's congratulations to Paul Helfenstein for "pulling" off another spectacular Skeet Shoot!

Thanks very much for that, Jason, and woops on the sulci labels -- I'll fix in an hour or two, have to go interview someone for Phoenix now. --Emily

Thanks again to Jason for pointing me to the location of that Rev 11 high-res shot -- I'd never have figured it out without help. The different lighting geometry made it especially difficult to match features. Still, I think things match up pretty well, except in the lower right corner of the image (on the map below -- you have to rotate PIA06251 180 degrees to get it in approximately the right orientation), which doesn't match at all. Weird.
