A collage of 4 views of Mercury provided by MESSENGER:
The top two shots are January flyby WAC shots in calibrated RGB color (contrast-stretched as noted in previous threads), below are the two highest resolution shots yet released in pseudo-color based on top composites. EDIT: Updated the inbound crescent with a higher resolution WAC shot just released. -------------------- |

Can we say that Skinakas doesn't exist? I don't see any basin.

Hmmm... no Skinakas? I see arc-shaped lobes of dark material, in some areas bounded by what appear to be old, degraded arcs of rimwall massif. I'm not a consummate image manipulator, but look within the crudely drawn red circle below: [attachment=16001:Maybe.JPG] I really do see a structure there that seems to be roughly concentric with that very roughly drawn red circle. Very degraded, yes -- the southern rim seems to have been obliterated by subsequent large craters. But this might be a basin, after all... -the other Doug From the longitude and latitude, the Skinakas Basin would've been the dark albedo circle just below yours. |

Skinakas was a ray-free area of cratered terrain, not a basin. I think a good analogy here is with the old Soviet Mountains in Luna 3 images - low resolution albedo interpreted as topography, which is unwarranted. See the link to the original Skinakas paper in post #56 above.

It looks like Tycho's all over...
The first close-ups are also in, I can't wait to see the pictures of the Caloris Antipoidal point. http://messenger.jhuapl.edu/gallery/scienc...mp;image_id=215 |

The level of detail in pic 217 looks eerily like a model of the lunar surface.

Here's the oblique view reprojected. So the feature on the right is the NW corner of what we've been calling the "southern basin" then? -Mike -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

Awesome, Ted! Thanks. I will say that the color is a bit wacky. I tried to tweak the images to match Messenger color. Since the filters don't come anywhere near matching, there were limits to how well this could be done. It is interesting how that one new ray crater dominates so much of the planet. -------------------- |

From caption for this image:
QUOTE "The crater in the upper right corner of this image is Boethius, which can also be seen in the WAC image released yesterday. These images overlap and will be used to produce the highest-resolution color mosaic ever obtained of Mercury’s surface."
