This is the first Mercury 3 image release enlarged and with the terminator brightened. The bright crater was seen last time too.

Latest image from the website, showing essentially the same thing as Phil Stooke was able to get by sharpening the image before.

And here's what he gets by enlarging, selectively brightening and sharpening this new image:

QUOTE (Ant103 @ Sep 30 2009, 05:38 AM)  My own sharpenning I just went to the Messenger site to see if any new pics down yet. But no. Although I liked yours, I thought I would take the "old" one and have a bit more of a look at the terminator while we're waiting.
Pardon my ignorance,but what's a wavelett????  |

Surprised no-one has commented on this glitch here:
http://www.planetary.org/blog/article/00002128/ I am hoping that whatever it was wasn't caused by something in the space environment close to Mercury, but was rather a purely internal programming thing that can be avoided by adjusting procedures. If it was a totally random event the timing is extraordinary (but not unprecedented - remember Iapetus). Anybody know anything more? |

That's reassuring, thanks Doug.
I think the latest image via peter59 already closes the gap at low latitudes. If I'm not mistaken the bright crater on the limb near the equator with the prominent northward trending ray is on the other side of 'terra incognita'. Also we can already see converging E-W rays in the southern hemisphere from the very prominent crater up ahead. |

This is the new view converted to an (approximate) stereographic projection. That makes craters near the limb circular so you can interpret features more easily. Very extensive smooth plains in the north.

The latest, via Twitter, is that MESSENGER safed just before closest approach. No high-res images on departure
 But since the flyby didn't involve any thruster firing, the gravity assist should have been successful. All approach imaging should have been done, so that last gore should be filled.

It also makes it look like Mercury just came out of the dryer.  -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/
