Rosetta scientific results Options

[remcook]

Freely available new papers with early OSIRIS results now online:
http://arxiv.org/abs/1505.06888 (Spectrophotometric properties of the nucleus of comet 67P/Churyumov-Gerasimenko from the OSIRIS instrument onboard the ROSETTA spacecraft)
http://arxiv.org/abs/1505.07021 (Comet 67P/Churyumov-Gerasimenko: Constraints on its origin from OSIRIS observations)

the second paper is particularly interesting, as it shows that 67P appears to be a contact binary after all

Obviously these papers are not for the general public consumption, because I hardly understood any of it, and all those equations !

[Bill Harris]

They are looking at the mechanics and seeing if Kepler, et al think that the contact binary could happen.

In a way, with an object that has formed through accretion, where is the line drawn on the size of the accretionary elements? Parts up to one-quarter to one-half Km in size are identifiable, in addition to the two major lobes. And different morphologies of different regions can be attributed to differences in erosional characteristics.

It's a whole different world.

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?

scientific results from Philae are now out on Science!

and shame on ESA, they are behind the paywall! Ehi guys, I paid for that probe!

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

Do comet fractures drive surface evolution?

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.
