Very nice indeed. This appears to expose a few gaps in the coverage of my Enceladus map. I'm wondering about what date the images for this mosaic were taken? I was thinking perhaps Feb 17, 2005 though I couldn't find enough raw images on the JPL page from that date that would cover all that particular territory. Any further info? Thanks!

Regarding gaps in the data;
I usually fill in areas that have missing data if the area is small. I only fill in at maximum 5% of the image. The B/W image has some data added in the upper right corner (you can easily see the cloning) Usually I try to find real data in lower resolution to fill in the blanks. (from other flybys/missions) I think that it is ok to do this because a black cut is more disturbing to the eye. This Ganymede image for example has luminance from galileo and color from voyager and a little synthetic data to fill some of the small holes: Gaymede in color This Europa image has data from two galileo flybys and i have used the different colorchannels to fill in the missing data. only one channel had coverage on the terminator. Europa will fix the colorbalance in this picture later. its a bit to red in the reds... /Mattias Just making pretty pictures

Young Enceladus
Summary - (Wed, 08 Feb 2006) It's easy to see the "wrinkly" features on the surface of Saturn's moon Enceladus. This actually means that portions of its surface are relatively young, and largely clear of impact craters. Its geologically active southern polar region is seen at the bottom of the image. This photo was taken on December 24, when Cassini was 108,000 kilometers (67,000 miles) from Enceladus. http://www.universetoday.com/am/publish/yo...dus.html?822006 -------------------- "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 |

Thought I'd mention an Enceladus map update. The latest versions feature several improvements including some high-resolution images from March 9, 2005 obtained (with VolcanoPele's help) from the PDS. A notable feature is a map sheet (processed by VP) that takes my cylindrical map, then provides accompanying polar projections along with feature names and lat/lon grid. All of this is being done at the 8K resolution.

A very nice bit of mapping... From both Steve and Jason. I always say, you can't know a place until you have a map of it.

QUOTE (alan @ Feb 22 2006, 08:57 PM) New Enceladus image http://saturn.jpl.nasa.gov/multimedia/imag...fm?imageID=2006 It never hit me until I saw this image, but the Galilean that Enceladus truly resembles is not Europa but Ganymede. The patches of ancient crust bordered with swirling rounded faults. There is surely a great size difference leading to differences in how features scale, and Enceladus seems not to have been pounded with any massive impacts the way Ganymede (and most saturnian icy satellites) had, and, of course, Enceladus has a living surface today while Ganymede seems not to. But the crustal dynamics on Enceladus today seem to resemble those on Ganymede maybe 3GYA. Europa, with its entirely reworked crust, is an entirely different beast. Maybe there's a continuum of cumulative activity that goes: Dione/Tethys Miranda Ganymede/Enceladus Triton? (may play by categorically different rules) Europa etc. |
