According to Dawn (who ought to know) the descent to the next mapping orbit is beginning now.
"NASA_Dawn NASA's Dawn Mission I'm done with Survey science operations today!! Time for a several-week transfer down to High Altitude Mapping Orbit (HAMO)!! 20 hours ago" Better pics on the way! Thanks, Dawn team, for the pictures so far. Will we learn of any preliminary nomenclature soon? Phil -------------------- ... because the Solar System ain't gonna map itself.

I haven't much informations about this, I know only, that it's from anonymous source in the Dawn team and it was one-time thing, so we must
wait now for another (raw) data until official release (~ end of year 2012). -------------------- |

Hi Machi, Our "raw" FC images are certainly not in 8 bit PNG format and we don't produce them in Photoshop, so what you obtained from this anonymous source cannot be described as raw. You had to work with what you had, and you did a fine job producing those color images, but it is beyond me how Emily can present your images on her blog as "nearly natural color". Stefan. |

Hi Stefan
QUOTE "Our "raw" FC images are certainly not in 8 bit PNG format and we don't produce them in Photoshop, so what you obtained from this anonymous source cannot be described as raw" Yes, I wrote this inaccurately. What I wanted to write is, that this kind of images (directly derived from real raw images, with some basic informations about them, which allow this kind of processing), will not be available until next year. All published images are without these informations, or they are strongly derived. QUOTE "You had to work with what you had, and you did a fine job producing those color images" Thanks! QUOTE "but it is beyond me how Emily can present your images on her blog as "nearly natural color"" Because source images are not in appropriate spectral bands and even more, I have no idea, if these are calibrated or not, I don't know exactly how close to "natural" these images are. Some published spectra looks flat for Vesta (in visible), so I tried similar settings for final images. For now, few images in "natural" colors was published (here) , so direct comparison is possible (btw these images are using red on 700 nm). ADMIN FORMATTING EDIT -------------------- |
