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.

Another “Color” View of Rhea

Color view of Rhea Against Saturn

Just as with the previous color image of Rhea, the same process was used to create this view of Rhea against Saturn.

This image was added to a set of images posted later as it was taken as part of the same approach as the others.

Rhea From about 50,000 km

Monday, September 3rd, 2007

Cassini actually passed within 5,000 km of Rhea (a moon of Saturn) on the 30th and took a multitude of images. All the closest images are quite bright and it is unclear if the moon is just that bright, if there was an anomaly in the process or if some basic calibration has yet to occur. At any rate here are more distant images from the flyby and what happens if you register the various filtered images into one RGB (red, green, blue) file in Photoshop. The IR1 (infrered) is placed in the red channel, the GRN is placed in the green channel and the VIO (ultraviolet) is placed in the blue and you get what is truly false color, but not very far from what other natural color images have shown in the past.

Rhea in IR1, GRN and VIO

Saturn (the solid color behind Rhea) seems a bit more green than expected… however, if the moon was starting to pass onto the side of the planet in darkness, it does tend to move toward green hues when in shadow.

Rhea from 5,000 km

Here is another one the further away images at 58,731 km in clear filter (B&W). You can see into one of the craters along the edge at the lower left side and peer across at the opposite side wall. It is similar to the close flyby images obtained of Dione and its deep canyon walls from last year.

And another clear filter from 61,602 km:


Wallpapers: 1024×768 Set 05

Saturday, August 4th, 2007


Managed to make the more common wallpaper size 1024×768 for the 14 most recent wallpaper posts (started with set 05 images, 1-4 to come). Download zip file here. Some were not produced as they just didn’t translate so easily into the format. However, the opposite is true in some cases such as for this image of the Martian south pole. Its resolution was hopelessly low for the larger landscape format, so now with the smaller size it was possible (just barely) to get it posted as a wallpaper.

Wallpaper: Rhea Portrait

Rhea is the second largest of Saturn’s moons but lacks any of the exciting features of some of the others. It has some of the “wispy” features that have been determined to be ice cliffs on Dione, but they are far less prominent here. Just another big ball of water ice for future earth visitors to mine for resources!

Wallpaper: Rhea and Saturn
The moon Rhea is pictured drifting across Saturn’s disc. Rhea is one of 3 medium sized moons (including Tethys and Dione) which are largely composed of ice with small amounts of rock and whose features consist mostly of craters. Rhea also displays the “wispy” lines that appear on Dione, so it is assumed that these are also ice cliffs as determined to be on Dione.

IMAGE NOTE: This image was not altered other than extending Saturn’s rings to fill the page on the right side. The original image was in square format so the subtle ring outlines were more cropped than seen here.
