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!

1986, I was 4. I don't know when exactly my interest in planets began, but by 4th grade, I knew more about the planets than the teacher did. I could recite the orbital times of all the planets, and the diameters of some. Most of that information came courtesy of Isaac Asimov's Library of the Universe books, which were thin but informative books made shorlty after Voyager 2's flyby of Neptune. One per planet and one for the Sun.
Still remember seeing The Grand Tour video, and cringing that it would be awhile until the 1997 launch of Cassini...and then the 7 year trip too. Just seemed like forever. |

Just seemed like forever. By the 4th Grade I knew the names of all the moons of Jupiter (only 16 back then). Now, with 63, I've given up trying. My interest in present day planetary science (i.e. not just what I could find in books at the school library) started with Galileo orbit insertion. -------------------- &@^^!% Jim!

QUOTE (volcanopele @ Jan 25 2006, 07:10 PM) But only 48 of them have names yet -- and by the time the rest are named, there will probably be another twenty added... My goal in that regard is "passive recognition" -- that when I see the name, I can say "oh, that's a Jovian moon" but the only ones I feel I ought to know are the ones discovered before the mid-70s -- back when I was young and the solar system was simple . My approach for the moons of Saturn, Uranus, and Neptune is similar. For asteroids, I don't even bother, but then who does? |
