Here are a few of the observations I've finished up in the last few weeks: ... Beautiful! Some fascinating images there. Nice colors too. I really like the way the landscape changes on Io from a smooth plain to a mountain of volcano! -------------------- _______________________

Wow... the "Pillan deposits" image is simply stunning. Don't think I've ever seen Io looking more.. diseased! So, just wondering, what is it about Io? Scientific reasons? Aesthetic reasons? I guess a little bit of both. I first became interested in Io for aesthetic reasons. It is, dare I say, a beautiful place. Europa and the other Galilean never really appealed to me. And my scientific interest grew out of that, into an interest in active geologic processes, Geology you can watch. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

It is, dare I say, a beautiful place. Indeed, it is a visually striking place, even in natural colors where it doesn't look like a pizza. From a visual standpoint it's definitely in my top 4 Galileans list. -------------------- |

Here is my take on the e11 image. Amalthea's color here is a mess, Io is generated from the three available filters, with the one non-binned image used to bolster the grayscale.

Impressive! Funny how these narrow-angles can play tricks on the eye in combination with the lack of atmospheric perspective in space. You could almost swear Amalthea's orbiting Io if you didn't know better.

You could almost swear Amalthea's orbiting Io if you didn't know better. Not only is there a lack of atmospheric perspective, but there is a lack of any familiar frame of reference to assess relative size and distance. -------------------- |

I've added six mosaics from the I24 encounter to my Galileo Image page. These mosaics make use of the scrambled images (that were later reconstructed at JPL) from that encounter. As far as I know, the full mosaics from these observations were never publically released, though snippets of a few of them were (though one was released as part of an anaglyph). These mosaics include some over the Pillan, Zamama, and Prometheus flow fields and over the mountains: Ot Mons, Tohil Mons, and Dorian Montes.
The images can be found at http://pirlwww.lpl.arizona.edu/%7Eperry/io_images/i24.htm A more extended description of these images can be found in the first two posts on the front page of my blog: http://gishbar.blogspot.com/ -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

24ISSTEREO01 What happened to the two fotprints that got displaced and caused gaps in coverage there? -------------------- |

Could the high radiation levels caused the pointing errors Gordan?

Possibly. The targeting of the whole mosaic is slightly off the plan, and the gap is certainly not there.

On rare events, frames are offset from plan by 1/4 frame or so. here is a rendering of the color sequence from I29 showing the tvashtar plume. note the cylidrical map projection! paul -------------------- Dr. Paul Schenk, Lunar and Planetary Institute, Houston TX

Here is a view I recently finished showing Loki on the terminator using I32 data.
Here is one with some high pass filtering mixed in. The downside is that it looks less realistic, the upside is that the terminator is easier to view. -------------------- |
