closest look at Mimas ... 30 minutes after periapsis on 02/13/10 at 17:25 UTC

"Thirty minutes after periapse, ISS will perform a targeted encounter with Saturn's innermost large icy satellite, Mimas. The altitude for this encounter is 9,510 kilometers (5,910 miles) the closest Cassini has ever gotten to this cratered moon. For this encounter, ISS will acquire three mosaics along with another observation where ISS will be riding along with the Composite Infrared Spectrometer (CIRS). ISS' first mosaic of Mimas, GEOLOG001, will start 30 minutes after closest approach when Cassini is 14,800 kilometers (9,200 miles) away from Mimas. GEOLOG001 is a seven-frame, multi-spectral mosaic of the region surrounding the crater Herschel. Herschel, at 130 kilometers (80 miles) across, is the largest impact basin on Mimas, so large that it caused significant amounts of stress on the lithosphere of the small moon and so distinctive that it helped give the satellite the nickname, "The Death Star Moon." These high-resolution observations of the basin will be used to estimate the age of the crater. Scientists will count the number of smaller craters on the basin floor, compared to other regions on Mimas, to set limits on how old the basin can be. The second mosaic, GEOLOG002, will also be a seven-frame, multi-spectral mosaic, this time covering most of the visible surface of Mimas, shown above left. The best resolutions for these two observations will be 87 meters (285 feet) per pixel for GEOLOG001 and 191 meters (626 feet) per pixel GEOLOG002. Next, Cassini will ride-along with a CIRS FP3 temperature map of Mimas' day side, acquiring six narrow-angle-camera images during the scan. Finally, ISS will acquire a full-frame, multispectral observation (GLOCOL001) of Mimas' anti-Saturn hemisphere from a distance of 70,000 kilometers (44,000 miles). Saturn will provide a backdrop for this observation."

Yes, exactly. These movies are taken over a non-insignificant fraction of the day for these moons. But it doesn't have to do with any interaction between the two moons.

[Poolio]

Okay, I get it. Thanks. So the rotation we're seeing is just the normal rotation of these moons. "Sunset", like Gordon said about 10 posts ago.

(I should know better than to post before doing my homework. The switching of orbits happened on January 21, more than three weeks ago.)

I finish colorize MIMAS. This dark areas are more visible.

Adam, it says "Limax 7" in the corner of your images. What does that mean?

It's my nick in polish forums: astro4u and astro-forum.org (the largest polish astro forums)
but also I use this nick in other groups: comet-ml

Final adjusted color composite RGB [IR1, GRN, UV3], with enhancement in the overexposed region:



The ridge at the limb to the upper right of Odysseus is likely a remnant of another large impact basin.

My mosaic is not of good quality, I hope that someone will do it better, but the view is impressive.

[ElkGroveDan]

My mosaic is not good quality,

It's underexposed.

Too contrast-stretched would be a better description.

Nice to see this moderately high resolution mosaic. Maybe advantageous for mapping.

I had already checked your site for a map update

[volcanopele]

I already tried updating my copy of Steve's map Steve, what size did you use for Mimas? Did you assume a spherical Mimas? I converted my mosaic to a simple cylindrical map and I can't get things to line up.
