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.

Fun With Io

Jason Perry’s most excellent Io blog (who would have ever expected there would be an Io blog one day) is loaded with his finely reprocessed Io images from the historic Galileo mission. Some of the more dramatic images were only captured in monochrome (that is black and white to most), so I thought I might try and colorize one of these images just for shits and giggles.

Fun with Jason Perry Images 01

The image is that of Hi’iaka Patera and two nearby mountains (taken in 1999). The tallest peak is about 11 kilometers high. The dark features are usually thought to be calderas, however the dark regions here could be depressions that were later filled by dark lava flows. Galileo took the images at from about 26,000 kilometers.

The colorized image is merely an artistic impression. You can see where missing data has been “filled” in with texture by comparing the two images and seeing where the composite left gaps. The color information is wholly interpretive and based upon colors that appear in many other Io images but are not at all matched up to the region specifically. The real image was processed by Jason Perry and the original image is located on his page of Galileo Io images from orbit 25.
