Someone tell him to feel free to violate the rule against in-line images. :-) --Greg Hi Greg, Only for you (well, no, for everybody in the forum), a brand new image is now available here. Enjoy -------------------- |

Fantastic! Thank you Pablo.
I wonder, could you tell us whether the protrusion at the bottom of the image is the central peak of the large south-polar basin? -------------------- |

Are my eyes failing me, or are there some darkish regions across the northern hemisphere of Vesta in this new image? Maria? (the lunar meaning of the word, not the Titanian one...)

I dunno if I'd go so far as to call them mares yet, but they do look like albedo features!

Careful- there seems to be an artifact in the released image apparently due to some glitch with the tone curve- you can trace a sharp boundary between two shades of gray all the way round the right limb and across the left-hand side.

Yeah, that is some kind of ugly processing that's been done on that photo...I'd like to post it but am hoping someone will come along and do something to it to make it look less artifacty. -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

I took my glasses off and a little blurred the picture is somehow more clear. Too much effort on the processing. |

Yeah - this is the point when I wish we could have the images at their native resolution and without the enlargement that's being applied.

My understanding was that some images would be relesed today?

Decepticon, on this very page of this very thread, an image released today has been linked to and is being discussed. You would almost have to be intentionally trying to miss it to not notice.

It looks like North is at the top, but I'm wondering if that south crater we had been anticipating based on the Hubble data is close to being as dominant as we had been anticipating.

"I wonder, could you tell us whether the protrusion at the bottom of the image is the central peak of the large south-polar basin?"
From what we have so far, I think that protrusion is on the rim of the big crater, not its central peak. The big crater is not going to look very dramatic except with grazing illumination as the seasons change. It's got to be quite old and battered - looks like quite a few superimposed younger craters.
