You need to upgrade your Flash Player The theme of this blog is not only and obviously space, but in particular “terrestrial worlds”, places that tend to have surfaces on which one could walk or at least attach oneself to. These places sometimes also have other earth-like familiar features such as atmospheres, weather, volcanos, geysers and perhaps, we are finding, even exotic oceans, rivers or lakes that are not necessarily made of familiar materials we are used to here at home. The second theme is imagery. Occasionally I do some retouching of images when needed if an image is incomplete or sometimes “dirty” or noisy. I will attempt to correct image shortcomings based upon other images or well-accepted presumed attributes. When this is done, notes will be offered as to what was added, why and sometimes how it was done. This way no one should ever wonder if something they are looking at is real or photoshop.

Mars: Basal Unit and Dunes

A recent post on unmannedspaceflight.com inquired “What’s your favorite view of the poles?” and Philip Descarfino (who did the colorization work) responded with the above image. According to Philip, “I find this image one of the best of HiRise so far. You really get the feeling of staring off into the distance from just above the surface instead of looking directly downward. It’s mostly an illusion, but it works quite well in this image.”

NOTE: Technically the image itself is interpretive in that it is not an RGB composite but instead a colorized black and white image based upon other color images from the same region. Usually you can almost tell from a glance when this is done, but this one looks spot on.
