Rosaly Lopes has a new blog post on the Planetary Society blog on the mysteries still surrounding Everyone's Favorite Moon (and if it isn't your favorite moon, then may a giant, falling chunk of komatiite greet you ). She aludes to the upcoming observations by New Horizons to study surface changes and volcanic activity on Io, and to an upcoming book, on Io. The book, Io After Galileo, is currently on Amazon, but rest assured, it will be available until early 2007. here is a link to the book's Amazon.com page: http://www.amazon.com/Galileo-Springer-Pra...TF8&s=books -------------------- &@^^!% Jim!

Sorry if this is the wrong thread, but I didn't see one about the reprocessing of Io images.
As you may know, some of the Voyager 1 images taken during the Io flyby are heavily smeared due to movement of the scan platform. Thanks to machi's tip about using the Parallel Iterative Deconvolution plugin for imageJ, I realized that some of these heavily smeared images could be restored to at least some degree. Just as Voyager 1 was about to make its closest approach, it took two three-frame longitudinal scans of the Moon, centered at around 300 degrees west and 5 degrees west. Judging from volcanopele's mosaic page, these images have a resolution somewhere around 400m/px. (Jupiter Viewer seems to output a wrong range to Io - 400,000 km - so I can't use that to calculate the resolution better). So without further ado, the deblurred mosaics: Io Longitudinal Scan 1 by Justin Cowart, on Flickr Io Longitudinal Strip 2 by Justin Cowart, on Flickr The most severe smearing was in the first frame of each sequence, so I'm guessing that's a result of imaging before the scan platform had entirely stabilized after slewing. Unfortunately I wasn't able to recover fine detail, but some of the larger features spanning several pixels have been recovered to some degree. At any rate I'm just happy to see some fresh new Io pictures I hadn't seen anywhere else on the web! |
