Here's a broad view of this geographically distinctive region (insert National Geographic narrator here). This mosaic was made from two isolated frames of 17ESREGMAP01 at approximately 220m/pxl, three frames from 17ESAGNEOR01 at about 180m/pxl, and a reprojected background image from 14ESGLOCOL01 (taken from an opposite perspective and lighting geometry) at 1.4km/pxl.

Ah, so you've imaged Thrace thrice? (Special award to anyone who can identify where I stole that joke from.)

Bah. That didn't take long.

I'm loving these images!

It's like reexperiencing the Galileo mission.

Theriousthly, Bruth, this harrathmenth abouth my speeth hath to thtop.

Interestingly, neighboring Thera Chaos was one of the first medium-resolution targets for Galileo at Europa during the prime mission, as it was positioned on the terminator (along with Cilix far to the north) during the C3 nontargeted encounter. Most of the structure is lost in shadow and radiation noise in the image. It's frustrating to realize how many fantastic opportunities for imaging coverage were lost to the high-gain failure. I recall seeing a footprint plot for the C3 high-res map of the terminator in the January 1996 issue of Astronomy that obviously predated the problem...

Here's the C3 image in two projections: C3ESWEDGES01c

Face it... as wonderful as it was, the Galileo orbiter mission we got was a "Salvage Job". <grumble-sigh>

This is the first of several planned presentations of medium-resolution Galileo mapping. This mosaic consists of 19 images from four separate observations of the southern antijovian hemisphere of Europa, most from the very productive E17 pass. An annotated version is included, along with the low-resolution E6 view used as the backdrop.

Libya Linea at high resolution. This view has an excellent example of the subtle undulations visible in these broad, relatively smooth expansion zones, with prominent fractures at the peak. Similar features are visible in Astypalaea Linea.

Don't forget that good color is available over this southern area, too--the same E14 global color that ted used to make his beautiful mosaics.

False color is here: Photojournal Thrace-Thera color

Very very impressive work exploitcorporations. It's great to see some of the galileo imagery reprojected and presented in these formats.
I'm in awe of the image manipulation that is showcased by many who post on UMSF - thanks for sharing.

Thanks for the kind words. I'm starting to get somewhat of a grip on color compositing. Here's a portion of the E14 mosaic referred to in vexgizmo's post:

Galileo obtained two high-resolution views of Agneor Linea during E17. This is the eastern one, covering the "fork".

And you are the master of the understatement.

Wonderful imagery! Europa is now taking on the appearance of another world instead of a pastel abstraction. Thanks.

Here's the western view of Agneor Linea, covering the area south of the "eye" in Katreus Linea. A four-frame crop of this mosaic was released by JPL in 1999. In the context view, the brightness of the central stripe has been exaggerated to match the background images.
