The usual baffled and awestruck comments. But below are the items they are struggling with:
Article :
Some of the craters are truly intriguing. One, located on the comet's largest lobe, has tall, thin rims. It resembles the crown-like splash-back you see when a liquid drop hits water in slow-motion....If the impactor is dense (rocky/metallic) then it likely produces a very deep, carrot-shaped cavity, largely by compacting pore space inside the comet, which then collapses to form a shallow depression on the surface.
But if the impactor were to be another low-density comet or cometary fragment then it is possible the cratering process may be more similar to rock-on-rock impacts....Another factor is cohesion. At such low-surface gravities, even very small amounts of cohesive strength (think blancmange) can support towering cliff-faces ...This may help explain the crown-like rim of that fabulous crater.

Whatever they come up with must involve an obligatory "impact event." Everything is an "impact event".
Article :
But the form that is stirring perhaps the most debate is the streaks that are apparent in 67P's narrow "neck" region....Are they a consequence of erosion, and possibly connected in some way to the boulders that clutter the neck terrain?...Or are they the result of some layering process, maybe when the body first formed and was accumulating material?
I wonder what the shape of these boulders will be, would anyone expect to see round smooth surfaces? Ice tends not to form boulders, but rather blocks like glaciers, right? At the neck it looks like the grand canyon if it were to have excavated entirely around the planet's equator.
The surface features are so diverse - and go from the very sharp to the very smooth.
Every snowflake is unique I suppose.
Sadly, we have not had a new picture this week from the Osiris science cameras, which see much more detail....The Max Planck Institute for Solar System Research, who own the Osiris views, are keeping them under wraps for the moment.
Under wraps is an interesting choice of words...
This is so full of BS I don't know where to begin!
But wait... yes I do! They're doing exactly as I said they would--like they're reading from an old movie script! For that matter any 12 year old could have written this press release. Just give them the paint by numbers template of responses. And, voila, they have a press release. What is so disturbing is that nothing challenges them. They assume immediately that the impactor was there!
And thanks, frantic, for the acknowledgments
Everything must be an "impactor" despite the nearly zero likelihood of such things ever occurring on such a tiny object.
And their bafflement over the exposed rock "neck" section with the carved channels. They said it was from erosion!!! LOL!!! Now they will look for the leprechaun unicorn "subsurface ocean" on the comet that carved the channels!
And yet the diverse terrain on such a small object--which dumbfounds them--will in actuality NOT change their theory!
They will explain it using impact events and "collisions when the two lobes merged to form the strange shape of the comet" The "merging" of the comet into one body will also account for the deep channels and everything else--even though it will actually not explain how the forms actually formed! That is the tragic hilarity to this
They will say something like this: "When the comet merged into one body from two, the stresses and torques created by this impact event created the channels and grooves on the "neck" and varied terrain. This was obviously done at the heavy bombardment phase of the primordial solar system. This also accounts for the multiple impact craters clearly visible on the surface; after all, comets are from the very early solar system as the surface of this comet truly shows as heavy bombardment. Also, the computer modeling predetermined parameters of belief we have been using has been proven correct once again as the comet has been gushing water from its unseen but subsurface ocean for weeks now. This further substantiates that Earth's oceans came from this comet."
Money well spent--pass the popcorn! More bullsh1t is on the way!
