Hi Phil. All of those mosaics are in reduced-scale form at the flickr link at the bottom of my posts now...the site they had been linked to was deleted in my long absence last summer. I will eventually have those dead links connected to the flickr page, and hopefully get those images up there at full size once I scrape enough change out of my sofa to get a paid account.

Here is one mosaic I really like and which I found only recently:
http://berlinadmin.dlr.de/HofW/nr/080/ Just 4 pictures assembled out of 30 taken during E19 in order to search for plumes. Anyway, the perspective is amazing ! Marc. |

It's so nice to see mosaic footprints aligning nicely in Galileo imagery. That's what a scan platform and a fast camera gives you, I guess. Were it not for forced JPEG-like compression, the imagery would have been very crisp. The PSF of the Galileo SSI camera was pretty tight and images could be sharpened nicely. Galileo may have had a lower resolution CCD than Cassini, but the image crispness more than compensated for it. It really was a capable camera...
All the more reasons to regard the loss of the HGA as catastrophic. -------------------- |

Take a look at the raws from the lunar flybys. Gives you an idea of what could have been done had the antenna opened.

May be this is not really new, but I just found it on the USGS planetary nomenclature site:
The big albedo features (bright plains and mottled terrains) on Europa have now official names (as Regio): Name (LAT / LON / DIAM) : Annwn Regio (20.0 / 320.0 / 2,300) Argadnel Regio (-14.6 / 208.5 / 1,900) Balgatan Regio (-50.0 / 30.0 / 2,500) Dyfed Regio (10.0 / 250.0 / 1,750) Falga Regio (30.0 / 210.0 / 2,500) Moytura Regio (-50.0 / 294.3 / 483) Powys Regio (0.0 / 145.0 / 2,000) Tara Regio (-10.0 / 75.0 / 1,780) I already knew about Argadnel and Moytura Regiones, but the other names seem to be quite new. Some new crater and Lineae names have also been assigned. Marc. |

Here's my version of the Europa 14ESGLOCOL01 mosaic using all color that was available. A lot of synthetic color at places, the terminator is pretty much only green filter data. Too bad about that huge gouge of missing data at upper left.
Color balance was roughly based on a Cassini RGB image showing pretty much an identical vantage point. Still slightly exaggerated colors, I think. -------------------- |

Good work. I primarily stole from the G-1 mosaic to fill that nasty gap.

That is a fantastic image. It sure emphasizes the "bloodshot eye" appearance of Europa (but I have to go from memory as it has been years since I went to a college fraternity party).

Really amazing work, G. The long troughs near the terminator really stand out in this view; don't recall seeing them as well in previous global mosaics.
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Really amazing work, G. The long troughs near the terminator really stand out in this view; don't recall seeing them as well in previous global mosaics. the long troughs are part of a global pattern. several other troughs elsewhere form part of a set of two giant circles on opposite sides of the moon. They actually match the stress patterns produced if you rotate Europa's floating ice shell almost 90 degrees (aka polar wander). check out the story at http://www.lpi.usra.edu/science/schenk/europaCropCircles/ paul -------------------- Dr. Paul Schenk, Lunar and Planetary Institute, Houston TX

Merry Christmas to everyone on the site!
(It's one of the highest resolution mosaic of Europa from Galileo, with resolution around 10 m/pix horizontal. Artificially colorised by average color of this regio (Lat. -8.55;Long. 215)) -------------------- |
