This is my attempt to reduce shading and jpeg artifacts and improve gamma/contrast fo everxposed region:

Is there any way of knowing the viewing angle? I'm wondering if Vesta is angled slightly oriented showing the south hemisphere, and we're looking into the South crater. You can vaguely see what looks like the rim of the big crater, and yes, very degraded.

Here's my shot at de-clipping the image. Warning: some artistic interpretation in the clipped border - I manually used a paintbrush to set the clipping mask.

Yeah, that is some kind of ugly processing that's been done on that photo...


You're not kidding. Add some lens flare and that could be one of mine...! laugh.gif

"Cleaned up" versions much better, well done everyone.

Yeah that one was uuuuugly. That swatch in the middle looks like it was cut with scissors and pasted on.

Images acquired from this time onwards should have over twice the resolution of the last released image. Can't wait to see more! smile.gif

Hi Greg,
Only for you (well, no, for everybody in the forum), a brand new image is now available here. Enjoy

I just now saw this. Thanks!

I usually tell people that UMSF is a place for serious amateurs who want to experiment with new ways to visualize data from unmanned space probes--and for the rest of us who just like to look at the pictures. I think it's very cool that you gave us a picture that was not just nice to look it; it gave people here a way to show off what they can do. :-)

Thanks again.

--Greg

Firstly, thanks to the Dawn team for posting this new image.

This can probably be seen by taking a look at the earlier rotation movie, even though its resolution is lower. Actually these approach images nicely illustrate the value of movies. The most recent image is much better than the earlier images but in some cases it's difficult to distinguish between topographic shading and albedo features. The difference between the two is more obvious in a movie. Here I get the impression that we are looking at both but it's difficult to be sure.

"Is there any way of knowing the viewing angle?"

Check out post 259 earlier in this thread. The movies are indeed very useful.

Today, Dawn is 60400 km from Vesta, which now appears as big to Dawn as the Moon appears to Earth observers. I suppose we could say that's some kind of milestone. An image of Vesta now would be close to 100 pixels across.

I prefer to look at this similarly to Earth received time for spacecraft events, only in this case it's a delay of N days until we all (the public) see that image. Not really much point in thinking how big Vesta appears to Dawn at this moment or how soon it's downlinked to the ground, is there? laugh.gif

True, and that's a problem, I think. Have to be honest here - and by this I mean no disrespect whatsoever to the fine efforts of the Framing Camera team's generosity with their time on this forum's Q&A, which is a brilliant gesture, thank you again! - but this is the first major mission in a long time that I haven't felt a part of, and that I've actually, sometimes, felt like my interest in the mission and its science isn't appreciated or wanted by the people at the head of it. That is probably very unfair, but it's how I feel. This lack of images is taking a lot away from Dawn and the revelation of Vesta for me personally. It feels more like we're in occasional contact with a submarine on a deep ocean mission, that only surfaces long enough to send back a burst of info before sinking beneath the waves again.

The images available now must be *wonderful*, but they're scattered across desks or sitting on hard drives, only being seen by a few people - who deserve to see them, obviously, but the world has moved on, and it means this is something of an "aloof" mission, I feel. Great shame.

Oh well. I'm sure the next image release will be fantastic, really looking forward to that. smile.gif

Agree Stu. It reminds me of the late 1970s when I used to have to wait for the weekly thin copy of Science News at the school library to get a photo or two from Viking. In fact under those circumstances I was seeing images MORE frequently than we are getting from Dawn.

I've agreed to host and present at a Vesta Fiesta event at our local museum to celebrate the arrival. I'm kinda hoping there are a few more images to show off or it's could be a less-than-enthralling presentation.....
