Regarding the few images released after the 6/5/2007 Messenger flyby of Venus:
http://photojournal.jpl.nasa.gov/catalog/PIA10124 The image caption states that 614 images were acquired. Are these available? After all these missions, there is still a lack of (available) visible-light (non-UV) images of the 2nd rock. |

That version did not correct for the nonsquareness of the pixels, so looks oval (and yellow). I like this version of the Mariner 10 global by Mattias Malmer. Also, here is a color (yes, color) view of Venus from the MESSENGER flyby data, processed by Gordan Ugarkovic.

That orange version is some derivative of my original image.
The original shows a gibbous Venus (Mariner 10 doesn't have that much distortion, the camera system is similar to Voyager's) and colors closer to Malmer's version. Mariner color data comes from Clear and Blue filters only. I subtracted the Blue data from the Clear (panchromatic) channel, thus creating a synthetic yellow chanel. Some interesting results also come from Venus Express ( http://www.astrosurf.com/nunes/explor/explor_vex.htm ): I feel that all those images hold up quite well. Some overall brightness and color variations are visible. The general tone is yellowish, but it depends a lot on the actual processing, image gamma etc. -------------------- www.astrosurf.com/nunes
