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.

Its not something we are likely to see again anytime soon, so it is especially nice of Ted to re-image these old voyager images. These are the definitive best shots of each of these bodies, with perhaps the exception of Miranda (second from left, note there is a tiny dark moon which is first). Of the Uranian family, Miranda also happens to be the most interesting (of what know) with its cracks and ridges that somewhat resemble those processes happening on Enceladus and Europa.

Ariel is the third of the five larger moons or Uranus. It is somewhat similar to Saturn’s Rhea in composition, about 30% rock and 70% ices. There are obvious ridges and details that would appear to be somewhat “young” features (which is still quite old to you and me), but there is little known about this moon as it was only viewed once from 127,000 km by Voyager 2.
