daily Ceres picture from the survey orbit
http://dawn.jpl.nasa.gov/multimedia/images...tml?id=PIA19572 I started a new topic, as we are no longer in the first orbit phase |

it'real this color images of CerES? Hi there, is a bit of time that I cannot come back here (it's not a good time) but I'm continuing to read. So, Daniele the color of these images can not be obviously real (they are black and white). Original files are on our Flickr album: https://flic.kr/p/tPP6Cq - https://flic.kr/p/tG8GKv In the description you will find a "vc" which stands for "virtual color" (we'll try to be more explicit but generally we are always in a hurry!). They were obtained with the same technique that we used many times for the Rosetta's comet. Although the colors may match with a good approximation to reality, the main purpose of making a black and white image in color is to emphasize the details. On the other hand, we find that our eye perceives really better in color. -------------------- |

There is a (somewhat false-) global colour map of Ceres, taken at near-infrared, green, and blue wavelengths: Perhaps you could use that colour information in your images? I'd imagine that the surface's appearance at near-infrared would be similar to what it looks like at red wavlengths. ~~~ Regarding the "mountain", did NASA or any other scientific organisation post an estimate of what it could be? -------------------- Curiosity rover panoramas: http://www.facebook.com/CuriosityRoverPanoramas

Yes, I know, it would be possible but maybe be worth waiting for better definitions .. and they are coming! -------------------- |
