I considered this an, uh, occipital illusion, and briefly discounted a local slope phenomenon since this is not a grossly potato-shaped world, but the local slope phenomenon is likely the most tenable.

Still, ain't Kansas... smile.gif

Several of the recent images can be joined to make a rough mosaic - the first one (left end) in its raw form and the rest distorted to fit it, very uncontrolled.

Hi Phil,
First of all, great job at mosaicking. Second, I just would like to point out that the dark patch south east of the snowman (and including part of the middle crater) are the region formerly known as Olbers. This is the kind of surprises the Vesta holds for us.
We hope to see these mysteries resolved soon!
Regards

ohmy.gif ...again. (That's why I've been hooked on UMSF since Mariner 9...)

smile.gif Never gets old, not a bit. We NEVER find what we expect, and of course that's why we go.

Latest picture of the day - an unusual hill:


http://dawn.jpl.nasa.gov/multimedia/imageo...p?date=20110908


But they don't say what's unusual about it, so I'm forced to offer my own theory. It resembles a whale - eye, mouth, fin, tail... head at the top. I think it's the whale from the Hitchhikers Guide to the Galaxy. Of course it could be something boring like a volcano!

Assuming the magma chamber is not uranium powered - what is the smallest body that can support a volcano?
Wouldn't Vesta be below that limit?

it could be a shadow of an unknown moon ... wink.gif

A whale-shaped moon!

Vesta is well known for its basalt crust, as shown by spectroscopy and the meteorites thought to have come from Vesta. So volcanoes can't be ruled out. The idea of a minimum size for volcanoes may crumble in the face of evidence. That's what Dawn is all about.

Dawn is approaaching to final orbit through a complicate set of maneuvers:

Happy to see now precise distances indication on simulator (because we are under 1 thousand miles!):

A glimpse of Vesta in colour!

(Alongside a visual/infrared false-colour image of the same bit of terrain.)

I wonder where on Vesta this is.

Simulator didn't update images in the last 14 hours! ph34r.gif mad.gif
Do someone knows the reason?

Have you tried sending them a friendly email rather than post an angry face here?

Good suggestion, Dough (I was hoping someone here was informed, but direct contact is better).
I received a kind answer after only 7 minutes by Judy Counley (Dawn site webmaster) telling that the responsible for simulator is already working on the issue! smile.gif

This picture is starting to show some very fine surface detail and texture. I can see why the science pros are tossing out some of their early hypotheses. There is more than enough weird stuff not like anything else seen to make me want to shut up theorizing until I've had a closer look.
Some of the topics for thought on the shaping of Vesta...
Extreme seismic phenomenon from South Pole impact. Contributor to Equatorial grooves? To smaller terrain shapes?
Extreme-but-transient electromagnetic phenomenon. (Impact, CME?)
Large structurally detailed albedo features relatively independent of surface terrain. Impacts of globs of stuff? Exposed dike/craton forms?
Ring collapse onto wobbly Vesta? Unlikely, with many ridge-groove areas non-great-circle. But if the impact sent out heavily-"rayed" debris, could it produce the right terrain on fast-rotating Vesta?

So many questions. More than before Dawn arrived...
