Before the T9 data came down, I got a little bored, and played around with some Voyager data of Ariel. The mosaic (oft produced) I generated is below. Again, this mosaic has been produced by a number of folks on the net, so this isn't really new, but I thought I would get this product out there anyway. I stretched the image such that only a few crater rims would have a DN=255 (other mosaics boost the contrast a bit too much, overexposing the ejecta around Melusine, for example. I also ran this image through a high pass filter, sharpening the image.
Enjoy! -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

Ted's stuff is great - keep it up! I hope you recover from your recent crash OK.
Not to ignore Rob Pinnegar's request - Hi Rob! - but I've been too busy to deal with it. Teaching again this term. If somebody wants to find those posts and link back to them that would be fine. I'd rather not post a second time. But too busy to search for the old post. Oops - gotta go! Phil -------------------- ... because the Solar System ain't gonna map itself.

Today, January 24, is the twentieth anniversary of Voyager 2's flyby of the planet Uranus, the first probe to that world.
http://voyager.jpl.nasa.gov/science/uranus.html http://en.wikipedia.org/wiki/Voyager_2 Four days later, nearly everyone forgot about this mission and its images of a bland blue ball. http://www.fas.org/spp/51L.html -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |

Okay, I'm officially old. Is there a face icon with a long beard and a cane? You kids - in my day probes only flew by planets and took crude black and white images that had to be sent back at 8 bits per second. And it had to be done in a snowstorm uphill both ways! -------------------- "After having some business dealings with men, I am occasionally chagrined,
