Dawn Survey Orbit Phase, First orbital phase Options

[antipode]

Hmmm, we're still a fair way away, but do I see some lobate flow features outside the rim of the lower torso of the snowman? That's also one HUGE boulder that seems to be sitting on what passes for a central peak! Finally, is it just me (or the lighting angles) but does the lower torso look sharper edged (and younger) than the upper torso?

I think there's one new image here:

The crater rim center top reminds me of old space art, with the ridiculous fumarole-like craters.

Two of six faces more or less complete. But I'm running out of 1x1 and 1x3 plates; the other 4 faces might have a little bit coarser resolution, or maybe a different color

Great model! My 7yr son approves!

Awww...

That looks ubercool thus far, Emily; thanks for a glimpse of the work in progress!

Re colors: Might be cool to do a topographical corolation with them of some sort, if that's at all feasible. The resolution of the model seems to be a couple square km per block or so..

Using two of the recent images of the snowman, I created a quickie anaglyph.

And it all started as a joke...

Cool!

Nice! It's interesting, that we still haven't true color images, only these with enhanced colors.

It's interesting, that we still haven't true color images, only these with enhanced colors.

The first press release after orbit insertion showed a color image from the imaging spectrometer that showed apparently visible wavelengths. It was completely white/gray with no visible color variation. I don't know if they normalized the reflectance to Vesta's average spectrum to get that, but even if they did, Vesta's actual color judging from Hubble data is very bland. I posted a colorized grayscale using Hubble 2-filter color data here, that should give you a rough idea on color intensity.

Oh, I already did one! I will do something more after dinner with Tayfun first model. See the old one here: http://youtu.be/qAkRunZl3eY (standard Celestia model for Vesta).

(It's not public, only accessible through that link because I used Adam Hurcewicz map found on this thread, and could not contact hime to ask for his authorization. Adam, is it OK if I make it public?)

Yes, Guillermo

I was in vacation and now I can write on forum.

Dawn's south polar region (from July 24, 2011)

That image was released 2 weeks ago -- why post it now? Was there something about it you wanted to discuss?

[elakdawalla]

I just noticed an oddity about how the Dawn images are posted. As usual, the punch line is: for the best quality version of an image, do not pass "Go," go to Photojournal and grab the TIFF.

Photojournal always has both TIFF and JPEG versions of an image. In rare, horrible cases, the TIFF has been made from a JPEG, but in most cases (including, as far as I can tell, Dawn), the TIFF is made from a file that was provided to the webmaster in some uncompressed format, and the lossily compressed JPEG made from that.

The NASA.gov website for Dawn is rarely updated with new image releases, so don't even bother going there.

As for the JPL Dawn website, you have to watch what you click on because there are a couple of different versions of each image. Go to the Image of the Day gallery and you'll see a bunch of thumbnails with brief captions. DO NOT CLICK ON THE THUMBNAILS. They take you to versions of the images that have been resampled to 700 pixels across, regardless of their initial size. Click instead on the "Full Image and Caption" link and then on the "Full Image and Caption" page go to the "Download Image > Full Size" link. The 700-pixel versions are the ones displayed on the "Full Image and Caption" page; they don't represent the original-res data. And they may even have been JPEG-compressed twice (once to make the "full size" JPEG, and again when saved as the 700-pixel version), but I'm not sure about that.

Or, like I said, just use Photojournal!

Will all the "images of the day" be going to Photojournal?
