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.

Through the Plumes!

Gordan of course.

The Fountains of Enceladus

Friday, November 27th, 2009

This has to be one of the greatest, most alien images ever taken from robotic spacecraft. It approaches how I might expect Enceladus to be depicted if it were in a Star Trek movie. As if the plumes at the edge of the disk back-lit by the Sun were not enough… the trail of smaller plumes breaking through the darkness is absolutely fantastic. The above is a real image but the color is an artistic interpretation by someone would know. Considering how little color is usually found at Enceladus, we can image this is really as good as if it were compiled from a full RGB set of filters. A larger monotone of the same image here.

This image was compiled by Astro0 on unmannedspaceflight.com. Also one of the best views staring down the length of one of Enceladus’ “tiger stripes”.

Ever so sharp look straight down on the South Pole of Enceladus from 1,855 km.

Rosetta Skims Earth

Friday, November 13th, 2009

On its way to a 2014 rendezvous with comet 67P/Churyumov-Gerasimenko, the European Space Agency’s Rosetta spacecraft, with JPL instruments on board, flew past Earth today to pick up energy.

The Plumes of Enceladus in Color (kind of)

Friday, November 6th, 2009

Like the Saturnshine image posted earlier, this is only an estimation of a true color image. Five sources were used to compile this image; clear 1, clear 2, red, blue and another clear filtered image was used to replace the missing green to round it out (this work by S_Walker from unmannedspaceflight.com). We then additionally cleaned out artifacts from the original images and blurred the surrounding geyser haze largely to eliminate posterization noise.

This is the first time anyone has been able to attempt a true color view of the geysers with the availability of the red and blue images. Also a bonus is the considerable amount of Saturnshine seen on the dark side of the moon.

Enceladus at 9,988 km

More coming. Looks like a nice encounter.

Dueling Enceladian Light Sources

Monday, November 2nd, 2009

Gordan U compiled this image of Enceladus lit both by Sun and Saturnshine. The side lit by reflected light from Saturn is in infrared and in the original appeared in a green hue. I took some liberties and imaged it as I would imagine it really would appear to the eye in Saturn’s more orange/yellow hues.

Worth noting tomorrow the images are due in from Cassini’s closest approach yet through its plumes. Hoping for some amazing material.
