Comet Chury's jets - before, during, after

emission of a jet on comet 67P C-G imaged on Nov 30, 2014

Comparison of the neck area of comet 67P C-G on images from ESA's Rosetta blog

here with some contrast processing (HDR) applied

Inset upper left Nov 30, during emission, background Dec 09
The "rilles" which appear to be new are located at the origin of  the jet.
Also the dark "smear" to the left of them seems to be more prominent now.

Comparison of images taken 2014 Nov 30, Oct 02, and Dec 09
Comparison  Nov 30, Oct 02, and Dec 09, 2014

The interpretation by ESA of the Dec 09 Rosetta NAVCAM image is rather cautious.

Follow the discussion started on the UMSF forum
"The latest Navcam blog shows new - or apparently new - features in the neck. Here's a comparison between October and December images (December on the right). I would suggest a close examination of images would probably show more things like this.

3D views of comet 67P and Philae landing site

To illustrate Philae's trajectory from first touchdown at Agilkia to its final landing spot I produced a 3D view (anaglyph) from the Rosetta OSIRIS NAC image of comet #67P C-G on Aug 03, 2014 and a screenshot from the pre-landing video by DLR.

On the comet's smaller lobe at right the Agilkia landing site is near the upper rim. The trajectory of Philae past or over the large depression to its final landing spot near the equator and the shadow of the polar night  can be well imagined. Follow the discussion on the UMSF forum

More illustrations and 3D anaglyphs in this Google+ gallery  or on  Picasa

Also a comparison of the public shapemodel of #67P on Github with the latest analysis in Rosetta Blog Nov21 Homing in on Philae’s final landing site  on a much more detailed 3D-model

as well as the latest anaglyph from ROLIS images
