OSIRIS observations of meter-sized exposures of H2O ice at the surface of 67P/Churyumov-Gerasimenko and interpretation using laboratory experiments

Some of the images on the paper in color here:

new paper: Large heterogeneities in comet 67P as revealed by active pits from sinkhole collapse
and as reported on the ESA site: http://www.esa.int/Our_Activities/Space_Sc...s_generate_jets

The spectacular sinkhole discovery and images have quickly hit mainstream media: http://www.bbc.com/news/science-environment-33354872

Outgassing from the newly exposed sides of a sinkhole: Has anything similar ever been reported before in planetary science?

The ESA Rosetta Blog announces a couple of new papers out on Rosetta, plus a couple of articles in the ESA Web Portal:

And post-perihelion bursts of activity:

http://blogs.esa.int/rosetta/2015/08/28/co...ch-22-august-2/

Yes, it's annoying to not have them available to everyone for review, discussion, etc. As (distant) 2nd best, there is something of a summary of the results published in Science at Popular Mechanics.

Also, the main articles aren't available without a subscription, but the supplements are. Some of those have interesting material. Just for example:

• CONSERT results
• Landing(s) of Philae and comet surface mechanical properties

The Philae Landing paper in particular has a bunch of interesting data, diagrams, graphs, photos, etc, relating to Philae's landing and flight across 67P. Just for example, they found the shadow of Philae on the 15:45 (post-first-impact) image and they include a couple of different possible reconstructions of Philae's post-impact trajectory--see attached.

Three papers on arXiv :

Gravitational slopes, geomorphology, and material strengths of the nucleus of comet 67P/Churyumov-Gerasimenko from OSIRIS observations
http://arxiv.org/abs/1509.02707

Temporal morphological changes in the Imhotep region of comet 67P/Churyumov-Gerasimenko
http://arxiv.org/abs/1509.02794

(nice OSIRIS pictures)

http://arxiv.org/abs/1509.03179
Rapid temperature changes and the early activity on comet 67P/Churyumov-Gerasimenko

Has any of the OSIRIS made it to a public archive yet?




Interesting idea, but I was reflecting the other day how the near- and post-perihelion activity has shifted from the neck region to the plains on the two lobes.

EDIT
And a new paper out on “Temporal morphological changes in the Imhotep region of comet 67P/Churyumov-Gerasimenko” to be published in Astronomy & Astrophysics:

http://dx.doi.org/10.1051/0004-6361/201527020

authored by Olivier Groussin, et al. http://blogs.esa.int/rosetta/2015/09/18/co...-rosettas-eyes/

And an announcement that Rosetta is to be taking station at 1500Km from the nucleus in late September
http://blogs.esa.int/rosetta/2015/09/18/ro...-coma-at-large/ . Mebbe they are expecting a big Kerblooie? Or just simply want the opportunity to get a series of wide coma images?

new blog post and OSIRIS images: Comet surface changes before Rosetta's eyes
be sure to check also the free access A&A paper it refers to: Temporal morphological changes in the Imhotep region of comet 67P/Churyumov-Gerasimenko

After hearing two good talks about the Rosina Zoo of organic molecule at the Rosetta Science Meeting I wait for the publication of the newly found molecules. Nice compounds which will create a lot of dicussions on how they are formed and how they can survive on a comet.

http://www.sciencedaily.com/releases/2015/...50730172518.htm

Is it from this work or from later data? There will no doubt be fascinating geochemistry based on temperatures and pressures _over the time period involved_ that would be impossible to duplicate in the lab.

--Bill

Sorry, but on this paper I am one of the coauthors, so this is not "new" for me. But the Rosina material is another teams data and so I have to wait for the meetings to get an update. The Zoo is large and the amount of compounds which can be still in the data and not yet identified might be large. I liked the groups made up by Kathrin Altwegg. The large ones and the small and flying ones an so on. I hope for a nice paper from ROSINA soon.

I'll (we'll) be looking forward to the new paper then. There is so much new ground being covered in this mission that we (y'all) will be working with it for years to come. And it all ties in with accretionary processes and the primordial solar nebula, which is quite mind-boggling.

ROSINA detects argon at Comet 67P
The noble gas argon has been detected in the coma of Comet 67P/Churyumov-Gerasimenko for the first time, thanks to the ROSINA mass spectrometer on-board Rosetta. Its detection is helping scientists to understand the processes at work during the comet’s formation, and adds to the debate about the role of comets in delivering various ‘ingredients’ to Earth

A fall of comet dust and a field of boulders

New papers of note:

"Redistribution of particles across the nucleus of comet 67P/Churyumov-Gerasimenko"
http://www.aanda.org/articles/aa/abs/2015/...aa26049-15.html

"Size-frequency distribution of boulders ≥7 m on comet 67P/Churyumov-Gerasimenko"

an entire issue of Astronomy & Astrophysics dedicated to Rosetta pre-perihelion results!

many articles are in open access, others may require a (free) subscription

Am I missing something, or are all but one of the start times wrong for Figure 3 in Table A.1 of Morphology and dynamics of the jets of comet 67P/Churyumov-Gerasimenko: Early-phase development? I don't read as many papers as a lot of you probably do, so I'm wondering if I'm somehow misinterpreting the table.

New paper and ESA Blog post:

Characterization of the Abydos region through OSIRIS high-resolution images in support of CIVA measurements

new paper in Nature:
Exposed water ice on the nucleus of comet 67P/Churyumov–Gerasimenko

not sure if this is best thread to post this but here is.. from phys.org with nice simulation movie: Comet 67P/Churyumov-Gerasimenko is much younger than previously thought

In this article&simulation, I'm missing a consistent explanation of the stratigraphy/layering on apparently any scale. Wouldn't such an energetic impact cause a much more heterogenious stratigraphy on the respective lobes?
