The same image slightly sharpened by me using ImageMagick, then I added some color.

Now compare this to the old Mariner 10 image (approximately true color):

I am amazed at how much data we get on this first flyby. And note, it is the fastest one before orbit insertion. NASATV has an animation of the flyby replete with high resolution mosaics, and good WA color images.

Another attempt at identifying the various craters in this latest image:

Sure, Ted. Is like to see an old friend, lost after elementary school... rolleyes.gif
I made a resume with further processing of your picture (perhaps too heavy?), joined to original + VP tentative identifications:

Getting closer. This one really shows quite a bit of detail. Particularly clear near the terminator is the multi-ring basin Vivaldi:

This already fills a small gap in the Mariner 10 map! A small patch missed between high resolution frames. Also, this area was seen by Mariner 10 with very high sun - near the sub-solar point. The inbound mosaic will improve our existing maps enormously. Then the outbound mosaic will be mostly new territory.

I think we may have already learned something new. The Mariner 10 stuff, from as far as I can tell, doesn't indicate that Vivaldi is superimposed on an older, larger impact basin.

EDIT: May not be an older basin. May actually be two impact craters to Vivaldi's southwest.

I processed it and colorized it based on my Mariner-10 work.

I am seeing numerous news reports that 700 GBytes of data will be returned by MESSENGER over the next 2 days. This, being an absurd value for reasons too numerous to count, is obviously a result of a bits/bytes or order of magnitude error. So what is the real amount that will be sent back over this flyby? I see that there are 2 banks of 8 Gbit solid state memory, the amount of data sent back on the Venus flyby was 6 GBITS at 600 images and there should be double that number on the Mercury flyby, the average bitrate at Mercury is 18 Kbit/s and the expected data return for 1 year after orbit insertion is only 135 Gbits................. an obvious actual value for this flyby is not jumping out at me....
