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.

Martian Avalanche!

Martian Avalanche Zoom Out

In the referential image above, two avalanches were captured in action by the Mars Reconnaissance Orbiter. The larger of these two (B) is around 180 meters wide, extends about 190 meters and the cliff heights are around 700 meters tall. The White material on the top that appears as snow is actually carbon dioxide frost which is currently receding as the Martian Spring moves closer. It is this very process which may be the cause of such falls as the carbon dioxide frost expands and contracts with the changing seasonal temperatures. Despite these seasonal changes, most areas of the Martian surface have likely been unchanged for millions of years, so it is quite rare to capture such cataclysmic activities in a single image from orbit.
