Enlargement & enhancement of Crescent Mercury.
It looks like the Skinakas Basin exists after all, despite being written off, though it is still a bit too soon to jump to that conclusion. The crop & blow up I have just done shows a large feature foreshortened in the northern hemisphere. We will definitely know more tomorrow, as this afternoon's image will be approx 25% closer to Mercury than this one. There also appears to be another large impact feature in the southern hemisphere. There is clearly a smattering of much smaller craters with bright ejecta blankets in the equatorial region. Northern horn of crescent Mercury. Looks like there IS a large circular feature foreshortened. I think it is the suspected Skinakas Basin. Obviously we will know much more tomorrow as the second Navigation image will be down, from much closer in. Every feature here is new to human eyes, very interesting & exciting.

Here's another version of the new image.
Isn't Skinakas supposed to be a dark area? Nothing on here can be interpreted as a large impact basin or 'mare' from this image. I'm on record saying Skinakas doesn't exist - we will soon know. Phil -------------------- ... because the Solar System ain't gonna map itself.

This spacecraft is really, really exciting!
Please excuse the uninformed question, but what is Skinakas? |

Please excuse the uninformed question, but what is Skinakas? Skinakas is actually a mountaintop in Crete hosting an observatory. A short story of the proposed "basin" (unfortunately named after it) is found here : http://en.wikipedia.org/wiki/Skinakas_Basin |

The next pic is up - here's an enlarged and processed version. A nice new basin in the south but nothing like that visible in the north.

And the next...
Phil The new southern basin's slightly lighter interior and dark spots suggest it might be a mini-Caloris. -------------------- ... because the Solar System ain't gonna map itself.

Hi Phil,
Certainly Skinakas Does Not exist. I really hope that the fifth image will be available soon. That southern basin is impressive. Certainly is reminicent of a mini Caloris. I've had a go at enlargening & sharpening each hemisphere from the original. Northern Hemisphere enlarged. Southern Hemisphere enlarged.

Yeah, looks a lot like Tolstoj (that dark-rimmed bright-centered thing in the southern hemisphere on the limb in the flyby 1 departure images). --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

That's the one I was trying to think of. Thanks, Emily. Nice central peak on that basin too.

Image # 5.
#5 Image Northern Hemisphere. #5 Image Southern Hemisphere. That basin is really coming into its own now. More dark spots are starting to appear on it's floor.

To me it looks less like a basin with dark spots, more like a basin with a mottled floor. Thats a bit pedentic I know but I wonder if there's a partial covering of dark lava flows on the basin (mottled) or if later impacts have excavated darker material (spots).

The feature highlighted here may be another old impact basin, overlapped on the north side by a later double-ring basin.
