This image is taken directly from the Cassini raw images directory. Sometimes they are perfect with no need for adjustment or correction. The best detail is the subtle haze of the geysers spewing on the right edge. Taken April 26 from 987,839 kilometers away.
This composite has been kicked around a bunch on unmannedspaceflight.com. Contained within it are two separate images taken by the Cassini mission at nearly the same time but different exposures. Looking at this scene with human eyes, the big difference would likely be that the geysers would not be blown out and would look more like a multiple of gentle hazes spewing upward. The other big difference would be that you were somehow on a mission to Saturn and not browsing the web.
Above are the two original exposures. These were merely combined with a photo editing tool. The geyser haze was blurred in areas to clean out compression artifacts and the color was artistically added by Gordan Ugarkovic. While the color is artificially generated, it does accurately reflect the same overall appearance of most natural light images of Titan.
If you haven’t followed the work of Stephen v2 and his film “Outside In”, you might want to take a look at what he has in store for us. Using only still images from the Cassini mission, Stephen is making a very impressive tour of the Saturn system without using any CGI, 3D models or textures. While those techniques make great Hollywood films they often fall short of making something that is actually a real place… look real. See below for a very brief clip of how this all ends up looking with a much better and longer clip coming in the near future.

This is one of the tiny moons of Saturn seen up close around Jan 27, 2010 by Cassini. In case you do not recall, it is the moon responsible for some of the best ring disturbance movies of the mission.
Sort of getting over the whole, “hey, we got two moons in the same frame” thing on the Cassini mission. But this one of Tethys ducking behind Titan’s thick hazy atmosphere kind of looks like a scene from a Star Wars movie.
Commonly known by most as that “Death Star Moon” — Mimas, is seen here in the some of the finest detail ever (and seen here in sick detail). Flying to within 9,500 kilometers (5,900 miles) of the moon, Cassini captured the infamous Herschel Crater dead center in the still frame. Herschel, a feature which upon its originating impact, likely came close to shattering the tiny moon into another Saturnian ring.
The image itself is a mosaic of several high-resolution images carefully placed together to make a full disc image. The lower right hand corner segment is (sadly) in a much lower resolution than the rest, but I’ll bet you didn’t even notice until I pointed it out and ruined it for you.
What it might have looked like to be riding Cassini as it rounded the pole of Iapetus from the last encounter. The animation was compiled using images composed by Gordan Ugarkovic.
I had really always thought it would be so cool to do a poster set with great design for each of the planets. I actually started a design for the Cassini at Saturn mission, but have yet to complete it. Sure enough someone comes along and knocks the whole system out in one fantastic series. Beat me to it!
Prometheus is the small moon that shepherds Saturn’s outer “F” ring and causes those crazy waves in the particles that make up the ring itself. The phenomenon has been the theme of at least 3 different animations here on wanderingspace.net. The image above is what that small moon in those animations looks like from 60,000 km taken by Cassini on Dec 26, 2009.
Haven’t come across too much lately. When that happens, I like to post these images that have been sitting around collecting virtual dust. Cloud top formations on Saturn taken by Cassini in 2009.
Gordan of course.
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.
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.
More coming. Looks like a nice encounter.
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.
