I've finally had time to chew on the approach color image. A first try resulted in progressive loss of color toward the terminator. This is not entirely bad, as the color signal-to-noise ratio goes to hell as brightness levels drop and fringing related to image registration imprefections increase with low-sun-induced contrast. Decolorize it in photoshop and it's probably to some extent a "best rendition" of the approach image. The second used the approach image with limb to terminator gradients removed and colorized it with color data separated out of the raw images separated out as R-B-versions. (Not quite raw, I had to subtract a zero-offset varying from 3 or 4 to 1 from each image to blacken data beyond the terminator.
Behold: The color diversity (in these bands) of Mercury (at least the approach crescent)

Fascinating. You can really see how Lava channels cut through the Highland terrain and flooded a multiring crater. Also, there is one of those funny pit craters in the middle of it (not sure if we have seen this one before or note.
I have attached an enchanced version of part of the image, both with arrows to show the channel, flooded crater, and pit crater, as well as a version with no arrows.

Wow...!!!
Just got back from holiday - can recommend Cyprus very highly, tho it tok some used to seeing Mars and Sirius so high in the sky! We saw a great Elvis impersonator on my birthday tho!  - and catching up with stuff... These latest MESSENGER images are nothing short of stunning, especially when you see them all in one go, like I'm doing now... BTW, anyone know what happened to the pics archive at: http://messenger.jhuapl.edu/gallery/sciencePhotos/pics ? There's nothing on that page when I go to it..? -------------------- |

They've locked that folder on their server I think - to stop the likes of us sneaking a peak of what's coming next.

QUOTE (Stu @ Jan 28 2008, 09:18 AM) Don't apologize for Caloris. Based on what I saw at APL, I'm sure that there will be important announcements at the press conference day after tomorrow. In NAC mosaic #2, it is *far* more interesting than it appears in the WAC pictures. I can't say more at this point, but prepare to see amazing detail across the N half of this hemisphere. |

I figured as much, which is exactly why I said in the poem: In the months and years to come I’ll share with you a better view, I swear: Great Caloris will be a gaping gunshot wound in Mercury’s furrowed forhead, but ‘til then instead you’ll know it as a mere memory of mayhem, an unknown wonder on a solar-wind baked stone… -------------------- |

Cool. Looks like it might be 2x2 binned, though. 288 full-res frames is a lot after all.
