Thanks for giving me hope. Can a quick colorization of this image of Miranda http://www.planetary.org/multimedia/space-...t-image-of.html image using the low res color data be done through? I'll attempt it myself, I just have very little experience with graphics editing and have only GIMP to use. I just feeling a color picture is more immersive in a "feel like being there" way and I don't wanna have a BW wallpaper and the color data for Miranda seem to be near uniform (basically it's all a very mild pinkish color). I'd be really thankful if someone did it, through I am gonna attempt it myself.

Here is my very quick and very dirty attempt using GIMP:
http://tinypic.com/r/akuz5c/9 using color from the NASA pic
http://tinypic.com/r/2zio48m/9 using color from the wallpaper pic

To be honest it sucks.

as an example of what phil posted ( post # 103 ) about needing to remap to add color and the LARGE amount of time needed to do it scientifically correct ( not a very fast job )

see my thread here

http://www.unmannedspaceflight.com/index.php?showtopic=8198

and this was a very fast and very quickly done example that would need about 8 or so more hours for a better job on just that ONE AREA

this dose take a lot of time to do right

I know...could a rough approximation be made quicker?

i might have some time on sunday ? maybe

BUT!!!!! there will be NO!!! color band corection from the Orange,green,Blue,violet , and UV images other than a guess ( NO MATH INVOLVED)
nor will i have time ti unwarp the images do to the lens distortion

the reasue marks ann lens distortion lines can be removed easily , so can missing lines of the image

making control nets are VERY time consuming , but some minor warping in the mapping can be done with just 3,4,or5 points and not 100+ points
but that is a very basic realigning of the remaped color filter images

for a very fast done sets for
Ariel , Umbriel , Titania , Oberon , Miranda,
now for the "rocks" in orbit there are spectragraph sets of data for the over color

but even some very fastly done color images of the major moons WILL take time
a few days if not a week or more

and right now i really do not have much free time so 2 to 3 hours at most a night a few nights a week

will take some time

Thank you. I really appreciate this. I feel like the moons of Uranus are underappreciated because of the somewhat unphotogenic pictures of them generally published and the great coverage of the Saturnian satellites vs those of Uranus. That creates a false impression of the Uranus's moons as boring despite Miranda's crazy geology, Ariel's likely past ammonia-water solution volcanism, Titania's tectonic features, Umbriel's dark terrain with a single white crater (reminds me of the dark side of Iapetus). The Uranus system should be something different than just a source of scatological jokes to native English speakers (I am not mentioning native English speakers out of prejudice, but because the "Uranus" jokes don't really work in any other language... my native language is Slovak and Uranus is called Urán here, same as the element of Uranium, I thought as a kid that Uranus was radioactive before I read about Voyagers and stuff, but the word for well that body part is completely different in Slovak).

In a way, I acquired a mild obsession about the Uranus system after NH arrived at Pluto. Currently, the moons of Uranus and the planet itself are the least explored rounded bodies in the Solar System apart from Kuiper Belt Objects other than Pluto. In particular Ariel and Miranda fascinate me with their geology.
