comment Why Aren't Saturn's Rings Clumping into Moons?
Sure, if you'd like to make one that's a reasonable file size for inclusion here, go for it. Those movies were over 200MB each, if memory serves, so I didn't embed it.

comment Why is infrared imagery of Mars' surface sharper / richer in contrast than that from the visible spectrum?
No. Really, what Olin said. Remember also that you're looking at different solar incidence angles, like when you take a picture of the full moon versus a crescent, the full moon looks less sharp than the crescent just because of the way the sun is hitting it. The IR mosaics that Google uses are from THEMIS which took images at late afternoon sun, while the optical (probably either Viking or Mars Orbiter Camera) were usually closer to noon sun.
