ZAZ: What comet? I see a couple dusty rocks.Or a fossilized mushroom. Hard to tell scale.
Mikey1969: Subby is technically right, as this is the only comet nucleus I've looked at today.Of course, this one came out a week and a half ago, and it's pretty much the same thing. Cool, but already waiting for something new. This is more or less a repeat.[www.esa.int image 700x525]
Twilight Farkle: [i.imgur.com image 640x584]That high-res image is not only gorgeous, it raises lots of questions. (I'm a layman, not a scientician, but I scribbled this together on the cropped pic because there's no such thing as a dumb question... )This thing's only spent about 50 years/fewer than 10 orbits that have taken it closer than 2.7AU to the Sun, so the answer to when some of these features changed may be sooner than one might ordinarily think. Best thing about this mission is that the spacecraft and lander will be along the ride through perihelion, so we might actually get to answer some of those questions in a few months' time.

HighZoolander: When I saw what you had done my first thought was that you were going Studman69 and sharp knees on the photo, as this comet had so many flaws it was way below your standards. But then I read your text and realized I probably spend too much time farking.
Tobin_Lam: With an escape velocity of only 1.5ft/s, an astronaut could jump from the head, over the neck, to the body. It would be a very slow and gentle jump, but it would span hundreds of feet, perhaps over 1,000! That would be so awesome.

jfarkinB: I was staring at that crosshatched patch, too. I see where you highlighted other faults that are parallel to one of the crosshatched directions. When I saw the scars running in the perpendicular direction, I got an immediate impression that they were scrapes.Imagine the "head" contacting the "body" for the first time. They're probably rotating independently, and if they're coming together slowly enough to stick without disintegrating, they're going to grind against each other until friction stops their relative rotation. I picture the head rotating slowly along its "horizontal" axis (as oriented in that photo), with the body gouging those "vertical" trenches as it turns. Plausible?
Lsherm: Not a geologist, so this may sound like a stupid question, but why are the faults at 90 degrees to each other a big deal? There's no "down" on a comet that's rotating, so wouldn't you expect faults to run in different directions depending on how they happened?
mark12A: Read an article somewhere (Slashdot??) that ESA is being a real dick and not releasing images promptly so *their* scientists could have the first crack at "making discoveries". And maybe "process" the images to cover up details so their scientists can reveal them later. Contrast this with NASA/JPL, who immediately release raw images as soon as they come in.
